Catches malware before it runs and automatically restores infected machines to a clean state without anyone stepping in.
SentinelOne installs software agents deep inside the operating systems of corporate computers — using security frameworks provided by Microsoft, Apple, and Linux — to intercept suspicious processes before they finish running, capture a snapshot of the system at that exact moment, and automatically roll the machine back to that clean state if the behavior turns out to be malicious. The snapshot has to be taken before execution completes, which means the agents need uninterrupted access to the kernel at every second, not just when an attack is detected, so the entire chain of interception, detection, and rollback depends on Microsoft, Apple, and Linux continuing to allow third-party agents inside those frameworks. Because the timing and coordination required to pull this off reliably takes years of validated work against each operating system's specific API behavior, a competitor cannot simply buy the same kernel access and replicate it — and a customer who has already spent months testing the agents across thousands of hardware configurations has little incentive to start over. The risk that holds the whole structure together is also the one that could collapse it: if any of those three OS vendors restricts third-party kernel access — something Microsoft began discussing publicly after the 2024 CrowdStrike incident — the pre-execution snapshot becomes impossible, and the platform loses the autonomous rollback that distinguishes it from conventional tools that only send alerts.
How does this company make money?
Customers pay an annual subscription fee based on how many endpoints are protected. Larger organizations or those who want additional coverage — like cloud workload protection or identity security — pay more through tiered pricing for those modules. The company also earns one-time or project-based revenue when customers need help deploying the platform or building custom integrations.
What makes this company hard to replace?
Deploying the agents across a large enterprise takes months of compatibility testing across every hardware configuration in the environment, and that work would need to be repeated from scratch on a competing platform. Customers also build custom connections between the platform and their SIEM systems and security orchestration tools; reconfiguring all of those integrations is a major project. The behavioral AI models also learn the specific traffic and process patterns of each organization's network over time, and that learned baseline cannot be exported or transferred to a competitor.
What limits this company?
Every time Microsoft, Apple, or a Linux distribution updates its security architecture, the agents must be re-tested and re-certified before they can run safely on machines with the new OS version. That knowledge — how each vendor's specific APIs behave at the kernel level — takes years to develop per platform and cannot simply be hired in. So each OS release creates a delay where updated agents are not yet cleared to deploy, and enterprise endpoints sit in a gap.
What does this company depend on?
The company cannot function without five inputs it does not control: the Windows Defender ATP APIs from Microsoft, the Apple System Extensions framework for macOS, the Linux eBPF kernel interfaces for system call monitoring, AWS cloud infrastructure hosting the Security Data Lake, and third-party threat intelligence feeds that train the behavioral AI models.
Who depends on this company?
Enterprise IT security teams build their incident response playbooks around the platform's automated remediation — if the agents fail, those teams lose the containment speed their procedures assume and must respond manually. Managed security service providers (MSSPs) running 24/7 monitoring operations rely on the platform's automated triage to keep analyst workload manageable; without it, the same volume of alerts would require far more staff. Kubernetes environments using the platform for container runtime security would lose real-time behavioral monitoring across cloud workloads.
How does this company scale?
The behavioral AI gets more accurate as more endpoints feed telemetry into the Security Data Lake, and the cloud infrastructure behind that data lake can expand with standard capacity additions. What does not scale the same way is the kernel integration work — each OS update requires deep, vendor-specific expertise that takes years to build per platform, so the engineering bottleneck does not shrink as the customer base grows.
What external forces can significantly affect this company?
European GDPR rules and growing data residency requirements in other regions force the company to replicate infrastructure locally wherever endpoint telemetry cannot leave a jurisdiction, adding cost and complexity. Geopolitical export controls on AI and cybersecurity technology block deployment in certain countries entirely. On the other side, insurance companies increasingly require enterprises to have autonomous response capabilities as a condition of cyber liability coverage, which pushes new customers toward the platform.
Where is this company structurally vulnerable?
If Microsoft, Apple, or Linux distribution maintainers close off the kernel access that third-party security tools currently use — a conversation Microsoft began after the CrowdStrike incident — the agents lose the interception point. Without that, the snapshot cannot be taken before execution. Without the snapshot, the autonomous rollback has no clean restore target. The whole platform collapses into a tool that only sends alerts after damage is already done, the same as conventional endpoint detection products.
