Department of War Authorizes Zscaler IL5 Platforms
March 23, 2026
The Department of War (DoW) has granted Impact Level 5 (IL5) provisional authorization to Zscaler's zero trust cybersecurity platforms, including Zscaler Internet Access (ZIA) and Zscaler Digital Experience (ZDX). This authorization permits these platforms to operate within unclassified defense environments, handling controlled unclassified information and national security system data. The milestone supports federal zero trust cybersecurity initiatives ahead of the FY 2027 deadline, enhancing secure cloud access and data protection for defense personnel.
- Why this matters: Procurement professionals should note that Zscaler's IL5 authorization positions the company as a key provider for zero trust solutions within DoW and related defense agencies.
- Agencies seeking to implement zero trust architectures can consider Zscaler's authorized platforms to meet IL5 security requirements for sensitive unclassified data.
- Contractors and partners working with Zscaler, such as Peraton and Lumen Technologies, may find expanded collaboration opportunities in defense cybersecurity projects.
- This development signals increased federal emphasis on zero trust compliance, guiding procurement strategies for cybersecurity solutions in defense environments.
The authorization covers Zscaler Internet Access, or ZIA, and Zscaler Digital Experience, or ZDX.
