SentinelOne is an AI-driven endpoint, cloud and identity security platform. See 2026 pricing tiers, key features, pros and cons, and top alternatives.
SentinelOne is an American cybersecurity company founded in 2013 and headquartered in Mountain View, California. It went public on the New York Stock Exchange under the ticker S and has grown into one of the largest independent endpoint security vendors, competing directly with CrowdStrike and Microsoft in the extended detection and response (XDR) category.
The company's core product, the Singularity Platform, replaces traditional signature-based antivirus with an AI-driven agent that runs autonomously on each protected device. Rather than relying solely on cloud lookups, the agent can detect, contain, and even automatically roll back malicious activity, including ransomware encryption, without needing constant connectivity to SentinelOne's servers.
Beyond the endpoint, SentinelOne has expanded into cloud workload protection (CNAPP), identity threat detection, and managed detection and response (MDR) services, positioning Singularity as a broader XDR platform rather than a single-purpose antivirus replacement.
Storyline is SentinelOne's core differentiator: it automatically links every process, file, and network event related to an attack into a single visual timeline, so analysts do not need to manually piece together isolated alerts during an investigation.
Purple AI, SentinelOne's generative AI security analyst, lets teams ask natural-language questions about their environment, such as showing all PowerShell activity from a host in the last 24 hours, instead of writing complex query syntax, which speeds up threat hunting for teams with limited security staff.
One-click remediation and rollback is particularly notable on Windows endpoints, where SentinelOne can revert files encrypted by ransomware to their pre-attack state using built-in volume shadow copy technology, reducing recovery time after an incident.
SentinelOne does not publish a self-serve pricing calculator; instead it sells through a tiered per-endpoint annual subscription model, with published third-party estimates placing Singularity Core near $69.99 per endpoint per year, Singularity Control near $79.99, and Singularity Complete near $179.99.
Add-on modules, including Cloud Security (CNAPP), Identity Threat Detection and Response, and Vigilance MDR, are priced and quoted separately depending on the scope of coverage an organization needs.
Because pricing depends heavily on endpoint count, contract length, and which modules are bundled, most buyers should expect to request a custom quote from SentinelOne's sales team; total annual spend commonly ranges from roughly $30,000 for small deployments to well over $100,000 for larger enterprise rollouts.
SentinelOne is an AI-driven cybersecurity platform that provides endpoint protection, endpoint detection and response, cloud workload security, and identity threat protection through a single agent called Singularity.
SentinelOne is sold as a per-endpoint annual subscription. Third-party estimates place Singularity Core near $69.99 per endpoint per year, Control near $79.99, and Complete near $179.99, though actual pricing requires a custom quote from sales.
No, SentinelOne and CrowdStrike are separate, competing publicly traded companies that both offer AI-driven endpoint detection and response (EDR/XDR) products.
SentinelOne typically offers trials and proof-of-concept evaluations through its sales team rather than an open self-serve free trial.
SentinelOne supports Windows, macOS, and major Linux distributions, as well as cloud workloads and containers.
SentinelOne is primarily built for mid-market and enterprise customers; its enterprise pricing and feature depth can be more than very small businesses need.
Purple AI is SentinelOne's generative AI security analyst that lets security teams investigate threats and query telemetry using natural language instead of manual queries.
Yes, SentinelOne trades on the New York Stock Exchange under the ticker symbol S.
