Server Hardening

Practical server hardening—access, exposure, patch posture, and prioritized remediation.

We harden servers against common failure modes and attack paths: SSH/RDP exposure, unnecessary services, privilege sprawl, patch posture, and basic audit logging. Deliverables prioritize what reduces risk fastest for your environment—without claiming certification outcomes you did not engage us to prepare for.
