ThreatLocker vs. SentinelOne Pricing & Hidden Costs
ThreatLocker uses a custom, environment-based subscription model rather than public per-endpoint pricing. Quotes are built around factors like endpoint count, application landscape, and required Zero Trust controls such as application allowlisting and ringfencing. Additional capabilities, including network control or patch management, are typically scoped into the overall plan rather than added later as surprise fees.
SentinelOne offers public, annual per-endpoint pricing tiers, including Core, Control, Complete, Commercial, and Enterprise. Costs increase as organizations move into higher tiers to access features like extended data retention, managed threat hunting, MDR services, and cloud workload protection.
ThreatLocker’s core strength is Zero Trust enforcement, operating on a default-deny model that only allows explicitly approved software and actions. Its key controls include Allowlisting, Ringfencing, Elevation Control, Storage Control, and Network Control to restrict what can run, how it behaves, and what it can access, helping limit living-off-the-land abuse and unauthorized lateral movement while enabling enforceable technical compliance controls.
SentinelOne’s Singularity platform centers on AI-driven EPP/EDR/XDR, using static and behavioral AI engines to detect and autonomously respond to known and unknown threats. Its capabilities span real-time prevention, detection, and automated remediation across endpoints (and extended tiers support cloud, identity, and managed services), with tech like Storyline linking related suspicious activity for richer context. Singularity also offers rollback and forensic features to recover from ransomware or destructive attacks without manual intervention.
