About SentinelOne

SentinelOne sells an AI-native platform with unified protection across endpoint, identity, AI, and cloud. SentinelOne describes its platform as powered by Autonomous Security Intelligence. SentinelOne states that attackers now use AI to generate code, move at machine speed, and exploit gaps. SentinelOne aims to stop attacks across AI tools, endpoints, identity, and cloud. SentinelOne offers solutions tailored to the regulatory, operational, and threat realities of specific sectors.[1][3]

SentinelOne's endpoint security platform combines endpoint protection (EPP), endpoint detection and response (EDR), and automated remediation in a single unified agent. SentinelOne combines EPP and EDR in a single platform, enabling prevention, detection, investigation, and response without separate tools or agents. SentinelOne uses behavioral AI to identify malicious activity based on how processes behave, not just what they look like. SentinelOne applies automated hardening to close gaps without manual intervention. SentinelOne's AI-powered EDR addresses ransomware, zero-day exploits, supply chain attacks, and fileless malware. SentinelOne provides autonomous, AI-powered protection across every workstation, every cloud workload, and every mobile device. SentinelOne deploys in SaaS, on-premises, hybrid, and air-gapped environments. SentinelOne's endpoint security integrates endpoint, identity, cloud, and third-party telemetry.[3][4]

SentinelOne contains identity threats from one console. SentinelOne detects credential theft, privilege escalation, and lateral movement as they happen. SentinelOne's identity protection addresses exposure across Active Directory and cloud identity providers including Entra ID, Okta, Ping, SecureAuth, and Duo. SentinelOne uses deception technology and conditional access policies to contain adversaries before impact.[4]

SentinelOne provides on-device mobile threat defense for iOS, Android, and ChromeOS users against phishing, malware, and risky apps. SentinelOne's mobile threat defense requires no MDM and works without connectivity. SentinelOne blocks network attacks such as man-in-the-middle, rogue Wi-Fi, and malicious profiles before they reach data.[4]

Purple AI and agentic workflows handle triage, correlation, and routine response. Purple AI investigates what analysts cannot reach in time. SentinelOne provides AI-native protection to detect, contain, and respond to threats in real time.[3][4]

Wayfinder IRR provides on-demand breach readiness, expert-led compromise assessments, and incident response. DFIR specialists conduct forensic analysis, identify root cause, and collect full-scope evidence, then contain the threat, evict the adversary, and guide teams through remediation. Breach Readiness exercises test plans and people against real-world threat scenarios. SentinelOne's exercises include tabletops, purple teams, war rooms, CTF challenges, and workshops. SentinelOne offers five assessment types: General, M&A, Post-Breach, Insider Threat, and Targeted. SentinelOne's incident response has a 4-hour SLA for initial expert response and a 24-hour SLA for preliminary findings. One retainer secures a renewable pool of expert hours used across readiness, assessments, and response. SentinelOne's response work covers end-to-end investigations, threat eviction, root cause analysis, IOC analysis, and malware reverse engineering. The response phase delivers executive reporting, compliance documentation, and actionable recommendations.[1][5]

Wayfinder Emergency Response delivers on-demand access with no commitment required. SentinelOne offers an immediate 40-hour on-demand DFIR block that requires no retainer. SentinelOne hunts for hidden, existing threats and undiagnosed malicious activity in the environment. Hidden threats are identified and neutralized by analysts and Google Threat Intelligence.[4][5]
