US Government Civilian Agency Secures Apps with the Zscaler Zero Trust Exchange
A U.S. federal civilian agency based in Washington, D.C., responsible for investigating major travel accidents, faced slow, complex access to cloud and datacenter applications caused by an aging firewall‑and‑VPN architecture and costly MPLS dependence. The legacy setup created latency, connection failures in remote offices, security gaps, and lengthy investigative workflows that needed a FedRAMP‑authorized zero trust replacement.
The agency deployed Zscaler’s FedRAMP‑authorized Zero Trust Exchange (ZIA and ZPA) to create a TIC‑in‑the‑Cloud and VPN‑free application access model, inspect encrypted traffic, and apply AI‑powered sandboxing for unknown threats. The move eliminated traditional firewalls and VPNs, enabled broadband and cellular paths in place of MPLS, cut incident investigation time by 50%, accelerated a secure AWS GovCloud migration, reduced IT burden and costs, and improved performance and inter‑agency collaboration.
