Keystrike Sanctum Guard ensures your servers receive only commands entered physically on your workstation, protecting remote servers from lateral movement compromise, even against stealthy attackers behind ransomware attacks. Sanctum Guard protects remote servers from lateral movement compromise, isolating stealthy attackers behind ransomware attacks. It ensures only authorized employees access servers, enhancing security without distracting them. Modern security practices segment computers into islands of trust. Keystrike Sanctum Guard secures the bridges between the islands. It integrates with your SIEM system and is compatible with your remote access setup. Sanctum Guard is officially supported in Microsoft Windows (8.1+) environments. Native macOS and Linux clients, and UNIX/Linux terminator for SSH/telnet sessions will be released in early 2024. Lightweight clients run in the background with a 20MB (client) and 40MB (terminator) memory footprint, ~0 CPU utilization, and a single outbound connection. Sanctum Guard ensures that traffic into sensitive areas originates from the authorized workstation, preventing unauthorized access. For sensitive or air-gapped environments, a fully on-prem Kubernetes version is available.
