Host & Kernel-Level
Server Hardening
Default server installations are riddled with insecure legacy protocols and open ports. We conduct forensic-grade hardening on Linux (Ubuntu, Debian, RHEL, AlmaLinux) and Windows Server machines, locking down kernel parameters, disabling vulnerable modules, and enforcing zero-trust isolation.
