Huge thanks to our episode sponsor, ThreatLocker
An attacker uses AI to create a payload your security tools have never seen. Detection now has to recognize it before the payload can act. ThreatLocker approaches the problem earlier by controlling whether that code is permitted to run at all. Explore a deny by default approach for your organization at threatlocker.com/ciso.
