SentinelOne AI is an autonomous AI-powered cybersecurity platform that detects, prevents, and responds to threats across endpoints, cloud workloads, and identities in real time without human intervention. Its Singularity platform uses behavioral AI to identify and block attacks in milliseconds — including ransomware, zero-days, and fileless malware — and automatically executes remediation actions. Enterprise security teams rely on SentinelOne to replace legacy antivirus with a platform that gets smarter with every threat it encounters globally.
