EDR

What is EDR — recording endpoint 'behavior' to detect and respond to attacks that slip through

EDR continuously records endpoint behavior, detects suspicious activity (IOA-style), and supports response (isolate, investigate). It catches fileless and living-off-the-land attacks that signature/IOC-based antivirus misses, via behavior and a timeline. Small teams often don't need full EDR — built-in OS protection plus logs plus the IOA mindset gets much of the value.
