Norton and Symantec are Legacy AV solutions. They (and many others) rely on signatures for threat identification. SentinelOne Endpoint Security does not use traditional anti-virus signatures to spot malicious attacks. Instead, we use a combination of static machine learning analysis and dynamic behavioral analysis to protect systems. All files are evaluated in real time before they execute and as they execute. Because SentinelOne technology does not use signatures, customers do not have to worry about network intensive updates or local system I/O intensive daily disk scans.
