Symantec Endpoint Protection, developed by Broadcom Inc., is a security software suite that consists of anti-malware, intrusion prevention and firewall features for server and desktop computers.

The first release of Symantec Endpoint Protection was published in September 2007 and was called version 11.0. Endpoint Protection is the result of a merger of several security software products, including Symantec Antivirus Corporate Edition 10.0, Client Security, Network Access Control, and Sygate Enterprise Edition. Endpoint Protection also included new features. For example, it can block data transfers to unauthorized device types, such as USB flash drives or Bluetooth devices.

At the time, Symantec Antivirus Corporate Edition was widely criticized as having become bloated and unwieldy. Endpoint Protection 11.0 was intended to address these criticisms. The disk footprint of Symantec Corporate Edition 10.0 was almost 100 MB, whereas Endpoint Protection's was projected to be 21 MB.

In 2009, Symantec introduced a managed service, whereby Symantec staff deploy and manage Symantec Endpoint Protection installations remotely. A Small Business Edition with a faster installation process was released in 2010. In February 2011, Symantec announced version 12.0 of Endpoint Protection. Version 12 incorporated a cloud-based database of malicious files called Symantec Insight. Insight was intended to combat malware that generates mutations of its files to avoid detection by signature-based anti-malware software. In late 2012, Symantec released version 12.1.2, which supports VMware vShield.

A cloud version of Endpoint Protection was released in September 2016. This was followed by version 14 that November. Version 14 incorporates machine learning technology to find patterns in digital data that may be indicative of the presence of a cyber-security threat. It also incorporates memory exploit mitigation and performance improvements.

Symantec Endpoint Protection is a security software suite that includes intrusion prevention, firewall, and anti-malware features. According to SC Magazine, Endpoint Protection also has some features typical of data loss prevention software. It is typically installed on a server running Windows, Linux, or macOS. As of 2018, Version 14 is the only currently-supported release.

Endpoint Protection scans computers for security threats. It is used to prevent unapproved programs from running, and to apply firewall policies that block or allow network traffic. It attempts to identify and block malicious traffic in a corporate network or coming from a web browser. It uses aggregate information from users to identify malicious software. As of 2016, Symantec claims to use data from 175 million devices that have installed Endpoint Security in 175 countries.

Endpoint Protection has an administrative console that allows the IT department to modify security policies for each department, such as which programs or files to exclude from antivirus scans. It does not manage mobile devices directly, but treats them as peripherals when connected to a computer and protects the computer from any malicious software on the mobile devices.
