Firewalls, VPNs, DNS filtering, and secure remote access tools need consistent care to stay aligned with how your team works. CSS helps maintain these controls so access remains stable, documented, and appropriate for users, locations, and protected data flows.
Maintenance may include rule review, subscription visibility, threat prevention support, secure gateway checks, and coordination with identity controls. The goal is practical: keep legitimate work moving while reducing avoidable exposure from stale rules, unmanaged access paths, or unclear network boundaries.
