Products and Services

Core Incident Management Platform

PagerDuty's core platform serves as the foundational system for handling IT operations disruptions, aggregating alerts from diverse sources such as monitoring tools, customer feedback, and support tickets into a unified interface for rapid and response. It employs configurable on-call schedules and escalation policies to notify and mobilize the appropriate responders, ensuring incidents are acknowledged and addressed without delay. To delete a schedule in PagerDuty, go to People > Schedules, select the desired schedule, and choose "Delete this Schedule" from the actions on the right. Confirm the action in the dialog window. Deletion is permanent and cannot be restored. Alternatively, pause or deactivate the schedule by removing it from escalation policies (recommended if historical data preservation is needed). PagerDuty prevents deletion of an on-call schedule if it has associated open incidents to avoid disrupting active incident handling. To delete the schedule, users must first resolve or close all linked open incidents or reassign them to another schedule if possible. Deletion is then possible only if the schedule is not currently referenced by any active services or escalation policies. The platform supports mobile accessibility and real-time updates, enabling teams to manage alerts across devices. Key functionalities include incident creation with detailed timelines, role-based assignments—such as Incident Commander for oversight, for documentation, and Liaison for communications—and automated workflows that guide remediation steps from detection through resolution. Integration with collaboration tools like Slack and facilitates ChatOps, allowing teams to execute commands, share updates, and track progress within familiar environments. This structure minimizes manual errors and coordinates multi-team efforts during high-stakes outages. The platform extends to post-incident analysis, generating reports on metrics like mean time to acknowledgment (MTTA) and mean time to resolution (MTTR), which users leverage for process improvements. With over 700 native integrations and extensible APIs, it connects to existing IT ecosystems for seamless flow, though customization requires technical setup. PagerDuty reports that adopters achieve up to 70% faster incident resolution times, based on internal benchmarks, though independent verification varies by implementation scale and configuration.

PagerDuty incorporates through its AIOps platform, which leverages to enhance by reducing alert noise, improving visibility, and automating processes. This includes Event Intelligence, a -powered feature that groups related alerts into single incidents, filtering out up to 98% of noise using techniques to minimize interruptions and alert fatigue. Introduced as part of PagerDuty's evolution in operations intelligence, these capabilities enable teams to focus on high-impact issues rather than sifting through redundant notifications. In addition to core ML-driven grouping and noise reduction, PagerDuty's AI extends to automation of repetitive tasks, such as event processing and initial response orchestration, allowing for faster resolution times and reduced manual intervention in incident workflows. The platform has supported these AIOps functions for over a decade, emphasizing secure and reliable AI integration tailored for IT operations. Features like intelligent alert grouping dynamically consolidate alerts based on patterns, further streamlining response efforts without requiring custom rules for every scenario. On October 8, 2025, PagerDuty launched an end-to-end AI agent suite, marking a shift toward agentic AI for autonomous issue resolution. Centered on a generative AI assistant, the suite detects anomalies in real time, orchestrates complex workflows, and automates end-to-end incident handling from notification to post-incident review, aiming to slash response times and mitigate burnout. These AI agents learn from operational data to handle routine incidents independently, transforming reactive into proactive, scalable operations while integrating with existing tools for broader enterprise resilience.

PagerDuty's platform has shaped incident management practices in and (SRE) by promoting standardized automation for on-call rotations, escalation policies, and integration with over 700 tools, reducing operational toil and enabling faster incident resolution in distributed systems. This approach has influenced broader industry shifts toward measurable reliability metrics, bridging development and operations teams to prioritize system uptime over siloed firefighting. A pivotal innovation came with the introduction of Event Orchestration in 2024, which automates alert grouping, , and standardization, allowing organizations to handle high-volume events at scale without expanding teams proportionally. Building on this, the PagerDuty Operations Cloud, unveiled in May 2024, unified AIOps, automation, and into a resilient framework that anticipates disruptions through machine learning-driven signal prioritization. Subsequent advancements in October 2024 included enterprise-grade AI agents and generative AI assistants, such as PagerDuty Copilot, which automate root cause analysis, stakeholder communications, and preventive actions, shifting teams from reactive responses to proactive resilience. These features have accelerated industry adoption of AI in operations, with PagerDuty's tools cited for enabling 30,000+ enterprises to minimize and fuel innovation velocity by reallocating resources from alerts to development.

Criticisms and Competitive Challenges

PagerDuty has drawn criticism for its pricing model, which reviewers frequently describe as high and lacking transparency, with core features such as advanced reporting restricted to premium tiers starting at $39 per user per month for the . Unexpected costs from add-ons, incident volume-based fees, and frequent upsells have led organizations to report budget overruns, prompting some to explore alternatives. Usability concerns persist, including a user interface perceived as outdated and convoluted, which has discouraged broader team adoption since at least 2015. Alert management has also faced scrutiny for generating excessive and latency in notifications, contributing to user and delayed responses in high-volume environments. A service outage on August 28, 2025, exemplified reliability issues, as it prevented incident creation and delivery of alerts, exacerbating customer frustrations for affected users. In the competitive landscape, PagerDuty faces pressure from established rivals such as Atlassian's Opsgenie, Splunk On-Call (formerly VictorOps), and BigPanda, which provide comparable on-call scheduling, escalation, and integration capabilities often at lower price points or with stronger event correlation to mitigate alert fatigue. Emerging challengers like Datadog's On-Call and Zenduty emphasize AI-driven noise reduction and transparent pricing, appealing to cost-sensitive SRE teams. Analysts have noted that intensified competition, alongside softening demand, poses risks to PagerDuty's annual recurring revenue growth and margins, with some institutional investors signaling caution as of September 2025.

Controversies

Regulatory and Financial Scrutiny

In disclosures filed with the U.S. Securities and Exchange Commission, PagerDuty has acknowledged limitations in its annual recurring (ARR) and related operational metrics, noting that these figures rely on internal assumptions that may not accurately reflect actual , future , or account for factors like cancellations. Investors have been warned against over-relying on such metrics due to their potential to mislead on health and lack of comparability with peer companies, as highlighted in analyses of the firm's risk factors. These concerns contributed to market skepticism amid slowing ARR growth, with the company reporting only 5% year-over-year ARR increase to $499 million in its second quarter fiscal 2026 results announced on September 3, 2025. On the regulatory front, PagerDuty experienced a exposure incident in late August 2025 stemming from a breach in third-party vendor Salesloft's Drift integration, which compromised including names, addresses, phone numbers, and limited API keys stored in systems. The company promptly notified affected customers and conducted an internal review, but no public regulatory investigations, fines, or enforcement actions have been reported as of October 2025. Such incidents carry inherent risks of scrutiny under data protection frameworks like the or EU , particularly given the involvement of , though PagerDuty's disclosures emphasize compliance with notification obligations. No securities lawsuits or formal SEC inquiries into PagerDuty's financial reporting have been identified in public records, distinguishing it from peers facing more acute enforcement. However, the firm's emphasis on metric caveats in SEC filings underscores ongoing investor diligence on SaaS valuation practices amid macroeconomic pressures on growth.

Operational and Sales Execution Issues

In fiscal year 2026, PagerDuty encountered significant sales execution challenges, including inconsistent performance in its North American market and difficulties scaling its go-to-market strategy. The company reported elevated customer churn rates, which contributed to declining net revenue retention and pressured overall growth. These issues led to a lowered full-year revenue guidance following Q1 results in May 2025, despite meeting quarterly revenue expectations, as enterprise deal cycles lengthened and core incident management product expansion lagged. To address these shortcomings, PagerDuty appointed a new sales leadership figure and adjusted its approach to better align with enterprise transformation efforts, though analysts noted persistent risks in execution that differentiated it unfavorably from peers. By Q2 fiscal 2026 earnings in September 2025, revenue growth stood at 6.4% year-over-year, in line with estimates but indicative of ongoing pressures from competitive dynamics and pricing model transitions. Operationally, PagerDuty faced scrutiny over its own service reliability, exemplified by a major outage on August 28, 2025, stemming from a failure in its Kafka message queuing system. This incident caused over nine hours of significant degradation in the service region, with 95% of events rejected at peak for 38 minutes and 18% of incident creation requests failing for 130 minutes, effectively silencing alerts for thousands of customer organizations reliant on the platform for incident response. The , triggered by metadata overload from millions of connections, highlighted vulnerabilities in PagerDuty's internal , ironic given its in digital . An earlier degradation on August 7, 2025, further disrupted service integrations and access for customers. In response, PagerDuty published a detailed post-mortem outlining improvements to heap memory management and handling, but the event underscored execution gaps in maintaining uptime for a mission-critical service.
