LexisNexis is an American data analytics company headquartered in New York, New York. Its products are various databases that are accessed through online portals, including portals for computer-assisted legal research (CALR), newspaper search, and consumer information.[3][4] During the 1970s, LexisNexis began to make legal and journalistic documents more accessible electronically.[5] As of 2006, the company had the world's largest electronic database for legal and public-records–related information.[6] The company is a subsidiary of RELX.

Key Information

History

[edit]
LexisNexis office in Markham, a suburb of Toronto, Ontario, Canada

LexisNexis is owned by RELX (formerly known as Reed Elsevier).[7]

According to Trudi Bellardo Hahn and Charles P. Bourne, LexisNexis (originally founded as LEXIS) is historically significant because it was the first of the early information services to both envision and actually bring about a future in which large populations of end users would directly interact with computer databases, rather than going through professional intermediaries like librarians.[8] The developers of several other early information services in the 1970s harbored similar ambitions (e.g., OCLC's WorldCat), but met with financial, structural, and technological constraints and were forced to retreat to the professional intermediary model until the early 1990s.[8]

An attorney named John Horty began to explore the use of CALR technology in 1956 to support his work on comparative hospital law at the University of Pittsburgh Health Law Center.[9][10] Horty was surprised to discover the extent to which the laws governing hospital administration varied from one state to another across the United States and began building a computer database to help him keep track of it all.[9][10]

In 1965, Horty's work inspired the Ohio State Bar Association (OSBA) to independently develop its own CALR system, Ohio Bar Automated Research (OBAR).[11] In 1967, the OSBA signed a contract with Data Corporation, a local defense contractor, to build OBAR based on the OSBA's written specifications.[11] Data proceeded to implement OBAR on Data Central, an interactive full-text search system originally developed in 1964 as Recon Central to help U.S. Air Force intelligence analysts search text summaries of the contents of aerial and satellite reconnaissance photographs.[12] (Before computer vision was invented, text summaries were manually prepared by enlisted personnel called "photo interpreters"; analysts then used those summaries as a catalog to retrieve photographs from which they could draw inferences about enemy strategy.[12])

In 1968, paper manufacturer Mead Corporation purchased Data Corporation for $6 million to gain control of its inkjet printing technology.[13] Mead hired the Arthur D. Little consulting firm to study the business possibilities for the Data Central technology.[13] Arthur D. Little dispatched a team of consultants from New York to Ohio led by H. Donald Wilson.[14] After Mead asked for a practicing lawyer on the team, Jerome Rubin, a Harvard-trained attorney with 20 years of experience was included.[15] The resulting study concluded that the nonlegal market was nonexistent, the legal market had potential, and OBAR needed to be rebuilt to profitably exploit that market.[15] At the time, OBAR searches often took up to five hours to complete if more than one user was online, and its original terminals were noisy Teletypes with slow transmission rates of 10 characters per second.[16] The original OBAR terminals were belatedly replaced with CRT text terminals in 1970.[16] OBAR also had quality control issues; Rubin later recalled that its data was "unacceptably dirty."[17]

In February 1970, Mead reorganized Data Corporation's Information Systems Division into a new Mead subsidiary called Mead Data Central (MDC).[15] Wilson and Rubin, respectively, were installed as president and vice president.[15] A year later, Mead bought out the OSBA's interests in the OBAR project, and OBAR disappears from the historical record after that point.[15]

After Wilson was put in charge, he became reluctant to implement his own study's recommendation to abandon the OBAR/Data Central work to date and start over.[18] In September 1971, Mead's management relegated Wilson to vice chairman of the board (i.e., a nonoperational role) and elevated Rubin to president of MDC.[15] Rubin pushed the legacy Data Central technology back to Mead Corporation.[15] Under a newly organized division, Mead Technical Laboratories, Data Central continued to operate as a service bureau for nonlegal applications until 1980.[19]

The old LexisNexis logo

Rubin then hired a new team to build an entirely new information service dedicated exclusively to legal research.[17] He coined a new name, LEXIS, from "lex", the Latin word for law, and "IS" for "information service".[18] After several iterations, the original functional and performance specifications were finalized by Rubin and executive vice president Bob Bennett in late summer 1972.[17] System designer Edward Gottsman supervised the implementation of the specifications as working computer code.[17] At the same time, Rubin and Bennett orchestrated the necessary keyboarding of the legal materials to be provided through LEXIS,[20] and designed a business plan, marketing strategy, and training program.[17] MDC's corporate headquarters were moved to New York City, while the data center stayed in Dayton, Ohio.[20]

Lexis was the first information service to directly serve end users. Rubin later explained that they were trying "to crack the librarian barrier. Our goal was to get a LEXIS terminal on every lawyer's desk."[8] To persuade American lawyers to use LEXIS (at a time when computer literacy was rare), MDC used aggressive marketing, sales, and training campaigns.[8]

On April 2, 1973, MDC publicly launched LEXIS at a press conference in New York City, with libraries of New York and Ohio case law as well as a separate library of federal tax materials.[21] By the end of that year, the LEXIS database had reached two billion characters in size and added the entire United States Code, as well as the United States Reports from 1938 through 1973.[20]

By 1974, LEXIS was running on an IBM 370/155 computer in Ohio supported by a set of IBM 3330 disk storage units which could store up to about 4 billion characters.[22] Its communications processor could handle 62 terminals simultaneously with transmission speed at 120 characters per second per user.[22] On this platform, LEXIS was able to execute over 90% of searches within fewer than five seconds.[22] Over 100 text terminals had been deployed to various legal offices (i.e., law firms and government agencies) and over 4,000 users had been trained.[22]

By 1975, the LEXIS database had grown to 5 billion characters and could handle up to 200 terminals simultaneously.[22] By 1976, the LEXIS database included case law from six states, plus various federal materials.[22] MDC turned a profit for the first time in 1977.[22]

In 1980, LEXIS completed its hand-keyed electronic database of all extant U.S. federal and state cases. The NEXIS service, added that same year, provided journalists with a searchable database of news articles.

In September 1981, Rubin and several of his allies (including Bennett and Gottsman) left Mead Data Central to pursue other opportunities.[22]

When Toyota launched the Lexus line of luxury vehicles in 1989, Mead Data Central sued for trademark infringement on the grounds that consumers of upscale products (like lawyers) might confuse "Lexus" with "Lexis". A market research survey asked consumers to identify the spoken word "Lexis". Survey results showed that a nominal number of people thought of the computerized legal search system; a similarly small number thought of Toyota's luxury car division.[23] A judge ruled against Toyota, and the company appealed the decision.[24][25] Mead lost on appeal in 1989 when the Court of Appeals for the 2nd Circuit held that there was little chance of consumer confusion.[26] Today, the two companies have an amicable business relationship, and in 2002 implemented a joint promotion called "Win a Lexus on Lexis!"

In 1988, Mead acquired the Michie Company, a legal publisher, from Macmillan.[27]

In December 1994, Mead sold the LexisNexis system to Reed Elsevier for $1.5 billion. The U.S. state of Illinois subsequently audited Mead's income tax returns and charged Mead an additional $4 million in income tax and penalties for the sale of LexisNexis; Mead paid the tax under protest, then sued for a refund in an Illinois state court. On April 15, 2008, the U.S. Supreme Court agreed with Mead that the Illinois courts had incorrectly applied the Court's precedents on whether Illinois could constitutionally apply its income tax to Mead, an out-of-state, Ohio-based corporation.[28] The Court reversed and remanded so the lower courts could apply the correct test and determine whether Mead and Lexis were a "unitary" business.

In 1997, LexisNexis acquired 52 legal titles (including the Lawyers' Edition) owned by the Thomson Corporation. Thomson was required to sell the titles as a condition of acquiring competing publisher West.[29]

In 1998, Reed Elsevier acquired Shepard's Citations and made it part of LexisNexis.[30] Before electronic citators like Westlaw's KeyCite appeared, Shepard's was the only legal citation service which attempted to provide comprehensive coverage of American law.[31]

In 2019, LexisNexis announced a joint venture with Knowable, a leader in contract data analytics.[32][33]

In February 2020, LexisNexis transitioned its database services to the Amazon Web Services cloud architecture, and shut down its legacy mainframes and servers.[34]

In 2020, Estates Gazette and the remaining business of Reed Business Information became part of LexisNexis.[35]

Acquisitions

[edit]
Main article: RELX § Significant acquisitions

In 2000, LexisNexis purchased RiskWise, a St. Cloud, Minnesota company.[36] Also in 2000, the company acquired the American legal publisher Matthew Bender from Times Mirror.[37] In 2002, it acquired a Canadian research database company, Quicklaw. In 2002, LexisNexis acquired the Ohio legal publisher Anderson Publishing.[38] In 2004, Reed Elsevier Group, parent company of LexisNexis, purchased Seisint, Inc, from founder Michael Brauser[39] of Boca Raton, Florida.[40] Seisint housed and operated the Multistate Anti-Terrorism Information Exchange (MATRIX).

In February 2008, Reed Elsevier purchased data aggregator ChoicePoint (previous NYSE ticker symbol CPS) in a cash deal for US$3.6 billion. The company was rebranded as LexisNexis Risk Solutions.[41]

In 2013, LexisNexis, together with Reed Elsevier Properties SA, acquired publishing brands and businesses of Sheshunoff and A.S. Pratt from Thompson Media Group.[42]

Sheshunoff Information Services, A.S. Pratt,[43] & Alex Information (collectively, SIS), founded in 1972,[44] is a print and electronic publishing company that provides information to financial and legal professionals in the banking industry, as well as online training and tools[45] for financial institutions. SIS was founded in 1971 by Alex and Gabrielle Sheshunoff. The company became recognized for providing guidance and analysis to the banking industry. In 1988 Thompson Media, a division of Thomson Reuters, acquired the company. Separately, the Sheshunoffs began publishing Alex Information products.

In 1995, SIS acquired A.S. Pratt & Sons. Established in 1933, Pratt's Letter is believed to be the second oldest continuously published newsletter in the country behind Kiplinger's Washington Letter, which began publication in 1923. A.S. Pratt is a provider of regulatory law and compliance work tools for the financial services industry.[46]

Gabrielle Sheshunoff returned in 2004 to unite the AlexInformation, Sheshunoff, and A.S. Pratt brands before it was sold to Thompson in 2008.[47]

In November 2014, LexisNexis Risk Solutions bought Health Market Science (HMS), a supplier of data about US healthcare professionals.[48]

In May 2022, LexisNexis acquired the behavioral biometrics technology provider, BehavioSec for an undisclosed sum.[49]

Data breach

[edit]

On March 9, 2005, LexisNexis made the theft of personal information of Seisint users public. It was originally estimated that 32,000 users were affected,[50] but that number greatly increased to over 310,000.[51] Affected persons were provided with free fraud insurance and credit bureau reports for a year. However, no reports of identity theft or fraud were discovered to have stemmed from the security breach.[52] The hackers stole passwords, names, addresses, and Social Security and driver's license numbers of customers of LexisNexis's Seisint division. Seisint collects data on individuals that's used by law enforcement agencies and private companies for debt recovery, fraud detection and other services.[53]

Commercial products

[edit]

LexisNexis services are delivered via two websites that require separate paid subscriptions.[54][citation needed]

In 2000, Lexis began building a library of briefs and motions.[55] In addition to this, Lexis also has libraries of statutes, case judgments and opinions for jurisdictions such as France, Australia, Canada, Hong Kong, South Africa, and the United Kingdom as well as databases of law review and legal journal articles for countries for which materials are available.

Previously, LexisNexis had a stripped-down free version (known as LexisOne) but this has been discontinued and replaced by Lexis Communities,[56] which provides news and blogs across a variety of legal areas.

Time Matters is a LexisNexis-branded software offering. Lexis for Microsoft Office[57] is a LexisNexis-branded software offering.

In France, the UK and Australia, LexisNexis publishes books, magazines and journals, both in hard copy and online. Titles include Taxation Magazine, Lawyers Weekly and La Semaine Juridique.

Lastly, LexisNexis focused on generative AI tool for attorneys called LexisNexis Precision that can produce memos defining key legal concepts, identify and summarize new case developments, and generate common legal documents.[58][59]

LexisNexis UK

[edit]

Butterworths

[edit]

The firm that became LexisNexis UK was founded in 1818 by Henry Butterworth (1786–1860).[60] He was a pupil at King Henry VIII School, Coventry. He left Coventry, was apprenticed to his uncle Joseph Butterworth, the great law bookseller of Fleet Street. In 1818, however, disagreement between them as to the terms of partnership made Henry set up on his own account at the corner of Middle Temple Gate (7 Fleet Street), where he became the well-known Queen's Law Bookseller.

Butterworths was acquired by International Publishing Corporation in 1965; IPC was acquired by the Reed Group in 1970.[61] Heinemann Professional Publishing was merged with Butterworths Scientific in 1990 to form Butterworth-Heinemann.[62] The Butterworths publishing business is now owned and operated in the UK by Reed Elsevier (UK) Ltd, a company in the Reed Elsevier Group. Publications continue to be produced by RELX (UK) Ltd using the "LexisNexis", "Butterworths" and "Tolley" trade marks. Such publications include Halsbury's Laws of England and the All England Law Reports, amongst others.

The Butterworths name is also used to publish works in many countries such as Canada, South Africa, Australia, and New Zealand.[63]

LexisNexis also produces a range of software, services and products which are designed to support the practice of the legal profession. For example, case management systems, customer relationship management systems ("CRMs") and proofreading tools for Microsoft Office.[60]

Other products

[edit]

InterAction is a customer relationship management system designed specifically for professional services firms such as accountancy and legal firms.[64][65]

Business Insight Solutions offers news and business content and market intelligence tools.[66][67] It is a global provider of news and business information and market intelligence tools for professionals in risk management, corporate, political, media, and academic markets.[68]

In 2025, LexisNexis launched Protégé, a personalized AI-powered legal assistant.[69]

Criticism and cases

[edit]

Illegal collection and sale of personal data

[edit]

In 2022, LexisNexis Risk Solutions was sued by immigration advocates for allegedly violating Illinois law by collecting and combining extensive personal information and selling it to third parties, including federal immigration authorities. The lawsuit claimed that the company's practices posed "a grave threat to civil liberties."[70]

[edit]

Critics accused LexisNexis of violating individuals' privacy rights by providing addresses, phone numbers, relatives' names, and more through the data being sold to Immigration and Customs Enforcement (ICE).[71]

In November 2019, several legal scholars and human rights activists called on LexisNexis to cease work with U.S. Immigration and Customs Enforcement because their work directly contributes to the deportation of undocumented migrants.[72]

Allegations of violating EU privacy legislation

[edit]

LexisNexis has been accused of violating the General Data Protection Regulation (GDPR) by collecting and storing personal data of European citizens without their explicit consent.[citation needed] The accusation was made by NOYB, a European privacy advocacy group, which filed a complaint with the Irish Data Protection Commission (DPC), the lead supervisory authority for LexisNexis in the European Union. NOYB alleges that LexisNexis collects personal data of European citizens through its legal research products and services, including Lexis Advance and LexisNexis® Academic. This data includes names, addresses, email addresses, and IP addresses.

NOYB also alleges that LexisNexis does not provide European citizens with an opportunity to opt out of the collection and storage of their personal data. This is a violation of the GDPR, which requires companies to obtain consent from individuals before collecting and storing their personal data.

In response to the complaint, LexisNexis has said that it is committed to complying with the GDPR and that it is currently reviewing its data collection and processing practices.

The DPC is currently[as of?] investigating the complaint and has not yet issued a decision. If the DPC finds that LexisNexis has violated the GDPR, it could impose a fine of up to €20 million or 4% of the company's global annual turnover, whichever is greater.

Withdrawal from China

[edit]

In March 2017, after being asked to remove some content, LexisNexis withdrew Nexis and LexisNexis Academic from China.[73]

Violation of Daniel's Law

[edit]

On March 4, 2024, two anonymous plaintiffs in New Jersey filed a class-action lawsuit against LexisNexis, stating that they violated Daniel's Law.[74][75] In New Jersey, Daniel's Law includes a clause requiring that if websites have published certain personal information regarding certain government officials, and a request to take it down by an authorized party is issued, such a request must be honored.[76] The lawsuit represents over 18,000 individuals, and alleges that not only were such requests not honored, but those who filed requests were punished by LexisNexis, who "campaign[ed] to freeze the credit reports of Plaintiffs and others", and incorrectly reported them as victims of identity theft. Furthermore, additional allegations state that LexisNexis published "comprehensive reports on other family members (including minor children as young as 13 years old)", and that as of the time of the lawsuit, none of the attempts to have LexisNexis unfreeze the credit reports have been honored.[74]

Privacy Class Action Lawsuit

[edit]

On April 17, 2024, a privacy class action lawsuit was filed against LexisNexis over its use of personally identifiable information. The lawsuit was filed in behalf of residents of at least California and Illinois.[77] The complaint claims that LexisNexis did so without plaintiffs' authorization in order to promote its Lexis Personal Records Products.

Other privacy cases

[edit]

LexisNexis has been in the news for a number of data privacy issues. In 2023, the company was fined €100,000 by the French data protection authority, CNIL, for failing to properly inform individuals about how their data was being used.[citation needed] The CNIL found that LexisNexis had not provided clear and concise information about its data collection and processing practices, and that it had not obtained the necessary consent from individuals to use their data.

LexisNexis has also been criticized for its use of facial recognition technology. In 2022, the company was sued by a group of privacy advocates[specify] who alleged that it was illegally using facial recognition technology to scan images of people without their consent.[citation needed] LexisNexis has denied the allegations; the case is still pending.[as of?]

The company has also been accused of collecting and storing excessive amounts of data about individuals. In 2021, a report by the Norwegian Consumer Council found that LexisNexis had collected data on millions of people, including their names, addresses, phone numbers, and social media activity.[citation needed] The report also found that LexisNexis was sharing this data with third-party companies without the knowledge or consent of the individuals involved.

However, the company has faced scrutiny over its data practices, including sales of personal information to entities for purposes, prompting debates on versus in an era of expansive data aggregation.

Corporate Overview

Founding and Evolution into Data Analytics

Mead Corporation established Mead Data Central, Inc. (MDC) in 1970 as a subsidiary following its acquisition of the Information Systems Division of Data Corporation, with the aim of advancing computerized capabilities. This initiative built on earlier experiments, such as the Ohio Bar Automated Research (OBAR) project initiated in the late to digitize state for efficient retrieval. Under the leadership of H. Donald Wilson, MDC's first president, the company developed proprietary technology to store and search full-text legal documents, marking a departure from manual index-based systems. In , MDC launched LEXIS, the world's first commercial online service, providing electronic access to full-text federal via dedicated terminals connected to mainframe computers. This revolutionized by enabling rapid keyword searches across vast document repositories, initially limited to Ohio and state courts before national expansion. By 1979, MDC extended its platform with NEXIS, a complementary service aggregating full-text news articles and business information from thousands of sources, broadening its scope beyond to general information retrieval and generating $22.9 million in revenues that year. The 1994 acquisition of MDC by Reed Elsevier for $1.45 billion led to the rebranding as , integrating legal and news databases under a unified while investing in technological upgrades, including delivery and . This period facilitated diversification, culminating in the formation of in 2000 to address growing demand for data-driven in sectors like and . Leveraging its expansive assets—encompassing billions of records from public and proprietary sources—LexisNexis shifted toward analytics platforms that apply statistical modeling, , and predictive algorithms to derive insights, such as fraud detection and evaluation, transforming from a retrieval-focused service to a comprehensive data analytics provider. By the , acquisitions like Lex Machina in 2015 introduced litigation analytics, enabling outcome predictions based on historical judicial patterns.

Ownership Structure and Headquarters

LexisNexis Legal & Professional operates as a business division of , a multinational information analytics and decision tools provider headquartered in London, United Kingdom. , formerly Reed Elsevier until its rebranding in 2015, is publicly traded on the London Stock Exchange (ticker: REL) and (ticker: RELX), with institutional investors holding the majority of shares as of its latest filings.

This structure prioritizes long-term customer retention over transactional sales, supported by continuous investment in AI and to enhance platform stickiness and value.

Historical Development

The development of automated legal research began in the late 1960s when Data Corporation, under contract with the Ohio Bar Association, created OBAR (Ohio Bar Automated Research), an early prototype for computerized access to Ohio Supreme Court opinions dating back to 1860. In 1968, the Mead Corporation acquired Data Corporation, integrating its information systems expertise. By February 1970, Mead reorganized Data Corporation's Information Systems Division into a new subsidiary, Mead Data Central (MDC), tasked with building a full-text, nationwide legal research database using advanced retrieval technology derived from military and early full-text systems. On April 2, 1973, MDC publicly launched LEXIS, the world's first commercial online service, initially providing full-text access to all and New York appellate cases, the U.S. Code, and select federal materials via dedicated terminals connected to mainframe computers. Early subscribers included four New York law firms, marking a shift from manual digest-based research to keyword-driven, full-text searching that allowed lawyers to query vast repositories remotely. This innovation relied on proprietary indexing and search capabilities, processing queries at speeds far exceeding print alternatives, though adoption was initially slow due to high costs—around $50 per hour—and the need for specialized training. Throughout the 1970s, LEXIS expanded its database to include federal circuit courts and additional state jurisdictions, reaching approximately 1,000 subscribers by decade's end, while MDC invested in user-friendly interfaces like the UBIQ terminal introduced in for major libraries. The system's causal impact stemmed from its empirical validation in reducing time; studies showed lawyers completing complex searches in minutes versus hours in libraries, though skeptics questioned its accuracy for nuanced legal interpretation without human oversight. In response to LEXIS's monopoly-like position, West Publishing launched competing in , incorporating topical digests alongside full-text, spurring market growth but highlighting LEXIS's pioneering role in digitizing primary legal sources. By the , LEXIS had grown to cover all federal and most state courts, with over 10,000 terminals installed by mid-decade, as declining hardware costs and improved enabled broader access beyond elite firms. MDC's focus remained on scaling the , including enhancements to citation validation and hyperlinking precursors, which solidified automated as a standard tool despite ongoing debates over and data completeness. This era's advancements laid the empirical foundation for LexisNexis's later mergers, proving full-text automation's viability through measurable efficiency gains in legal practice.

Expansion Through Acquisitions and Digital Shift (1990s-2000s)

In 1994, Reed Elsevier plc acquired Mead Data Central, the parent of Lexis-Nexis services, for $1.5 billion and rebranded the entity as LEXIS-NEXIS, providing capital and global reach for broader expansion beyond core legal and news databases. This ownership shift facilitated integration with Reed Elsevier's publishing assets, including mergers like Butterworth Legal Publishers and The Michie Company into a unified legal publishing arm. By 1998, LEXIS-NEXIS bolstered its legal publishing capabilities through the $1.65 billion acquisition of Matthew Bender and Shepard's Citations from Times Mirror, adding comprehensive treatises, citators, and secondary sources to its electronic offerings. Parallel to acquisitions, LEXIS-NEXIS pivoted toward internet-enabled access amid industry-wide movement from proprietary dial-up networks to web-based platforms. In 1996, it introduced ReQUESTer, a low-cost ($59/month) internet service targeting small businesses with basic public records searches. The following year, 1997, marked a key digital milestone with the launch of lexis.com, the first web-based legal research service for U.S. professionals, featuring streamlined case synopses and browser compatibility to reduce reliance on dedicated software. Complementary services like Xchange provided free web access to current legal news, signaling adaptation to open internet protocols while maintaining subscription-gated depth. Into the 2000s, acquisitions diversified beyond traditional into and international markets. In 2000, LEXIS-NEXIS established its Risk & Information Group and acquired CourtLink Corporation to enhance electronic court dockets and litigation . Subsequent deals included the 2002 merger with Quicklaw Inc. to form LexisNexis and acquisition of MBO Verlag for German legal content, alongside 2004's purchase of Seisint for advanced data linking in investigations. These moves, coupled with a 2004 global technology platform rollout, supported scalable online delivery and expanded content to over 40,000 databases by mid-decade, reflecting strategic layering of proprietary data with digital infrastructure.

Recent Growth and Technological Advancements (2010s-2025)

In the , LexisNexis expanded through a series of strategic acquisitions to bolster its data analytics, , and offerings, completing 33 acquisitions overall with peak activity in 2014 (six deals) and 2013 (four deals). Notable early-decade moves included the December 2010 acquisition of State Net, enhancing legislative tracking capabilities. This period marked a return to revenue growth following prior challenges, driven particularly by the risk solutions segment, with (LexisNexis's parent) reporting overall subscription revenue increases in legal and risk areas. The 2020s saw continued consolidation, with three acquisitions in 2022 and two more in the subsequent years through 2023, focusing on enhancing and compliance tools. Financial performance strengthened, as evidenced by RELX's underlying growth of 7% and adjusted operating profit growth of 10% across its divisions in , attributable in part to LexisNexis's expansions in AI-enabled risk and legal solutions.

Controversies and Responses

Data Security Breaches and Incidents

In December 2024, , a focused on data analytics and , experienced a security incident where an unauthorized accessed sensitive personal information stored in repositories used for . The breach, occurring on December 25, 2024, exposed data on 364,333 individuals, including names, addresses, phone numbers, addresses, Social Security numbers, dates of birth, and numbers. The intrusion went undetected until April 1, 2025, when LexisNexis was alerted by the third-party platform provider; subsequent investigation confirmed the . Notifications to affected individuals began on May 24, 2025, with filings to state attorneys general, such as Maine's, detailing the scope. In response, the company offered two years of complimentary credit monitoring and protection services to mitigate potential risks. The incident has prompted investigations by law firms into potential class-action lawsuits, citing delays in detection and notification as factors increasing vulnerability to , account takeovers, and financial crimes. No evidence of misuse has been publicly confirmed as of mid-2025, though the exposure of high-value identifiers like SSNs heightens long-term risks in a where brokers like LexisNexis aggregate vast personal datasets for commercial and purposes.

Privacy and Regulatory Compliance Disputes

, a focused on data analytics, faced a lawsuit filed on August 16, 2022, in state court, alleging violations of state laws through the unauthorized collection and sale of extensive —including names, addresses, phone numbers, and associations—to third parties, including immigration enforcement agencies.

In April 2024, another federal was initiated against LexisNexis and its parent Group in the U.S. District Court for the Central District of , accusing the companies of unlawfully disclosing vast troves of personally identifiable information (PII) from millions of Americans to third-party advertisers , purportedly to generate revenue. Plaintiffs argued this breached federal and state privacy statutes, including the (CCPA), by failing to provide mechanisms or transparent disclosures; the case highlighted broader concerns over data brokers' opaque monetization of consumer data. Compliance disputes under the (FCRA) have also arisen, as in the 2011 case Smith v. LexisNexis Screening Solutions, where plaintiffs alleged the firm neglected reasonable procedures to ensure maximum accuracy in employment background checks, leading to erroneous reports that caused job denials. Courts have partially dismissed related claims, such as in Ramirez et al. v. (filed 2022, ruled April 2024), ruling that certain privacy rights asserted by plaintiffs did not exist under existing law, underscoring tensions between practices and evolving statutory interpretations. A March 2024 class action in involved over 18,000 law enforcement personnel suing LexisNexis Risk Data Management for alleged retaliation—such as increased scrutiny or denial of services—following requests to remove their from databases, claiming violations of state laws. This suit raised questions about enforcement of data deletion rights under frameworks like the CCPA, though no regulatory fines were imposed. Following a December 2024 disclosed in May 2025, which compromised PII of 364,000 individuals—including Social Security numbers, addresses, and phone numbers—via unauthorized access to a third-party platform, LexisNexis faced a proposed federal alleging inadequate safeguards and failure to notify affected parties promptly, potentially breaching notification requirements under laws like the CCPA and state statutes.
