Deep dives
Threat Locker and Zero Trust Security
Threat Locker's EDR software uses a zero trust approach to enhance security on systems. By initially operating in a learning mode for a week, the software logs executables and processes, creating a tailored policy for the system. Once established, anything not on the allow list is automatically denied access, preventing possible exploits. This proactive stance, complemented by features such as ring fencing and dynamic access controls, significantly bolsters defense against malicious attacks.
