EDR Last Gasp
Protection against disabling security products
EDR Last Gasp provides protection against defense evasion techniques used by 78% of ransomware groups to disable security solutions. The system monitors the integrity of security product processes, detecting attempts at termination, memory modification, or bypass via safe mode. Even if an attacker gains administrator privileges, Last Gasp prevents protection from being disabled and sends an alert to the SOC.
