Frequently Asked Questions

How does SentinelOne compare to CrowdStrike Falcon?

The biggest architectural difference is that SentinelOne's agent runs behavioral AI locally on the endpoint, providing protection even when offline. CrowdStrike Falcon relies more heavily on cloud-based analytics, which means stronger threat intelligence feeds but reduced offline capability. On pricing, SentinelOne publishes list prices starting at $69.99/endpoint (Core) up to $229.99/endpoint (Commercial), while CrowdStrike's Falcon Go starts at $59.99/device but caps at 100 endpoints. Both achieved top marks in the 2024 MITRE ATT&CK evaluation, though SentinelOne reported 100% detection with zero delays, while CrowdStrike scored 100% detection and 100% protection.

Does SentinelOne work offline without an internet connection?

Yes. SentinelOne's agent uses on-device static and behavioral AI to detect and block threats without needing a cloud connection. Ransomware rollback and endpoint isolation also function offline. The agent does need periodic connectivity for management console updates, policy changes, and uploading telemetry data, but core protection continues on disconnected endpoints.

What operating systems does SentinelOne support?

SentinelOne supports Windows (including legacy versions back to Windows XP), macOS (including Apple M1/M2 chipsets from agent version 21.5+), and 13 Linux distributions. It also covers Kubernetes containers, cloud workloads on AWS, Azure, and Google Cloud, and IoT devices. Mobile support includes iOS, Android, and Chrome OS. SentinelOne consistently leads in time-to-support for new Windows and macOS releases.

Does SentinelOne offer ransomware rollback?

Yes. SentinelOne can reverse ransomware-encrypted files to their pre-attack state using Windows Volume Shadow Copy (VSS). The rollback is a single-click operation from the management console. SentinelOne also offers a ransomware warranty for Windows agents that guarantees no ransomware attack will cause irreparable damage, provided specific deployment and policy configurations are in place.

How does SentinelOne compare to Microsoft Defender for Endpoint?

Microsoft Defender for Endpoint is included in Microsoft 365 E5 ($57.00/user/month), making it significantly cheaper if you already pay for that license. SentinelOne's advantage is stronger cross-platform support (Windows, macOS, and Linux treated equally), on-device AI that works offline, and autonomous ransomware rollback. In MITRE ATT&CK evaluations, SentinelOne has consistently outperformed Defender, which logged 24 missed detections in recent rounds. Defender is the practical choice for Microsoft-heavy environments using Azure AD and Intune; SentinelOne is stronger for mixed-OS fleets.

What is SentinelOne Purple AI and which plans include it?

Purple AI is SentinelOne's generative AI security analyst built into the Singularity platform. It lets analysts query threat telemetry using natural language instead of writing structured search queries, which accelerates investigation and threat hunting. Purple AI is included starting from the Singularity Complete tier at $179.99/endpoint. The Enterprise tier adds an Agentic AI SOC Analyst that can autonomously triage alerts without human involvement.

What compliance certifications does SentinelOne hold?

SentinelOne holds SOC 2 Type 2, ISO 27001:2022, ISO 27017, ISO 27018, GDPR, HIPAA, PCI-DSS, Common Criteria, CSA STAR Level 1, and Cyber Essentials certifications. In 2024, the Singularity Platform and Data Lake achieved FedRAMP High authorization, which is the U.S. government's most rigorous cloud security compliance standard. The platform supports SSO with MFA and role-based access control across all tiers.

Will SentinelOne slow down endpoint performance?

SentinelOne's agent is designed for minimal resource impact. It uses static file AI and behavioral AI instead of traditional signature-based scanning, which eliminates the need for constant .dat file updates and daily full-disk scans. System requirements are modest: 1 GB RAM (2 GB recommended) and a 1 GHz dual-core CPU. Users and reviewers consistently report that the agent runs silently in the background without noticeable performance degradation, though resource consumption will vary with system workload.
