U.S. Federal Agencies Push Zero Trust Security Overhaul

Federal civilian agencies are mandated by the Office of Management and Budget’s M‑22‑09 memorandum to adopt a zero‑trust security model, measuring progress against the CISA Zero Trust Maturity Model. The shift moves away from perimeter‑based defenses toward continuous verification of every user, device, network, application and data access. Implementation faces hurdles such as legacy systems, identity sprawl, cultural change and procurement timelines, often requiring specialised integrators to modernise infrastructure.

Operationally, organizations report a widening gap between zero‑trust intent and policy reality. Frequent cloud migrations, temporary access grants and outdated firewall rules create policy drift, where rules become broader than needed and compliance evidence erodes. Security teams must manually reconcile fragmented identity data, logs and change tickets to validate and tighten access, a process that slows remediation and expands the attack surface. Experts warn that without automated governance, the daily residue of changes can undermine the effectiveness of zero‑trust programs.
