SentinelOne Singularity Platform

Modern IT environments have expanded in size and complexity, multiplying internal and external threat vectors and rendering perimeter-focused security insufficient for distributed networks, hybrid clouds, and remote work. This shift has pushed cybersecurity toward faster detection, analysis, and remediation before damage occurs. Endpoint Detection and Response (EDR) emerged to collect endpoint telemetry, enable remote investigation, and support response actions; long retention has become crucial because adversaries increasingly run slow, stealthy campaigns that may remain dormant for weeks or months, as illustrated by Sunburst’s delayed trigger. EDR tools have evolved into broader endpoint protection, detection, and response platforms, using machine learning to reduce alert fatigue and align detections with frameworks like MITRE ATT&CK.

However, endpoint-only visibility is incomplete in heterogeneous environments, driving parallel development of network and cloud-focused tools and culminating in XDR, which consolidates telemetry and analytics across endpoints, networks, and clouds. Unlike traditional SIEM approaches that pull logs, XDR emphasizes real-time telemetry pushed to the platform for faster correlation, AI-assisted detection, and automated hunting, forensics, and remediation workflows.

SentinelOne’s Singularity Platform is positioned as a unified security data ingestion and analytics platform that has expanded from “next-gen EDR” into true XDR coverage across endpoints, networks, cloud workloads, IoT, and mobile. A single autonomous endpoint agent supports Windows, macOS, and Linux (including VMs and Kubernetes workloads), performing real-time behavioral analysis and static pre-execution scanning to replace signature-based antivirus. The platform emphasizes autonomy (including offline operation), long historical visibility (up to 365 days), event correlation via Storyline, automated rule-driven response via STAR, network discovery and control via Ranger, and expanded cloud and mobile protection through Singularity Cloud and Singularity Mobile. An open ecosystem with integrations, marketplaces, optional retention, and managed services supports incremental adoption, while challenges remain around third-party remediation breadth, maturing mobile integration, and limited lower-tier packages.

• Traditional perimeter-focused security tools are described as inadequate for distributed networks, hybrid cloud architectures, and remote work.
• EDR solutions collect endpoint telemetry via agents, store it for a period of time, and allow remote investigation and mitigation.
• Adversaries commonly design slow attacks that can remain dormant for weeks or months before triggering.
• The Sunburst attack was designed to trigger after 15 days.
• SentinelOne is headquartered in Mountain View, California, and was founded in 2013.
• SentinelOne acquired Scalyr in February 2021.
• EDR benign and malicious data retention is available for up to 365 days.
• Storyline Active Response (STAR) became available in August 2021.
• Singularity Mobile was released in December 2021.
• Over 25 technology partnerships are mentioned, including Zscaler, Mimecast, and Azure AD, with SIEM export support to IBM QRadar and Splunk.

• “Traditional perimeter-focused security tools no longer can provide adequate protection in the era of distributed networks, hybrid cloud architectures, and employees working from home.”
• “Retaining a sufficient time span of historical data is more critical than ever since adversaries now commonly craft slow and stealthy attacks that might remain dormant for weeks or months before triggering.”
• “As opposed to SIEMs, telemetry is pushed into XDR platforms in real-time, not pulled from logs, allowing for much more rapid correlation and analysis.”
• “Powered by an autonomous AI engine built directly into its endpoint agent, the solution aims to respond to a wide range of threats in real-time without the latency of the cloud.”
• “In contrast to traditional EDR solutions, SentinelOne captures and analyzes all activities - good and bad - on each managed device…”
• “The agent can perform local AI analysis in real-time without the latency introduced by communicating with the cloud.”
• “A full attack storyline can be visualized in seconds…”
• “Essentially, this solution replaces manual proactive threat hunting with a highly automated, extensible alternative…”
• “Architected according to the Privacy by Design principle, Singularity Mobile is filling the remaining functional gap…”
• “Despite retaining the same name, the new SentinelOne Singularity Platform is a completely new, much more capable security analytics and incident response solution with an open ecosystem.”
