Reach Security Partners with Knox Systems to Pursue DISA Impact Level 5 Authorization
Partnership will accelerate Reach's path to bringing AI-driven security controls assurance to the Department of War and its mission partners
WASHINGTON, Nov. 11, 2026 /PRNewswire/ -- Reach Security, the AI that operates security defenses at machine speed, today announced it is partnering with Knox Systems (Knox), the largest, longest-running federal managed cloud, to pursue Defense Information Systems Agency (DISA) Impact Level 5 (IL5) Authorization. A rigorous U.S. Department of War (DoW) standard, IL5 authorizes cloud service offerings to host Controlled Unclassified Information (CUI) and unclassified National Security Systems data, accelerating the adoption of secure commercial cloud solutions for the DoW's most sensitive unclassified missions.
Defense and federal security teams run complex environments built from many tools, and misconfigurations, underused capabilities, and configuration drift can open blind spots that are slow to find manually and quick for AI-powered adversaries to exploit. Reach Security gives security teams a central source of truth for their security controls, showing which existing defenses already stop a given attack, prioritizing action according to real-world risk and available control capabilities, remediating weaknesses or deploying compensating controls, and continuously validating that controls remain aligned with security policy.
Reach Security's mission is to help security teams close gaps in defenses before AI-powered attackers can exploit them, while ensuring security controls remain aligned with organizational policy and established security baselines. Its platform provides an AI-native operating system for security controls, continuously analyzing the security control plane across identity, endpoint, email, firewall, Secure Access Service Edge (SASE), and other critical defenses.
"AI has given attackers the ability to find and exploit weaknesses at machine speed, and federal defenders need the blue side of that loop. Reach Security turns the attacks and exposures that adversaries and red teams uncover into defensive action, using the security controls agencies already own to rapidly deploy remediation or compensating controls before attackers can take advantage of them," said Garrett Hamilton, CEO and co-founder of Reach Security. "Partnering with Knox to pursue DISA IL5 is an important step toward bringing that autonomous defense to the sensitive, highly regulated environments where it matters most."
Knox's IL5 landing zone is purpose-built as a separate, dedicated boundary that meets the elevated security, isolation, and operational requirements necessary to support high-impact defense missions while simultaneously enabling technology companies to enter the environment faster. By eliminating the need to build and operate a standalone IL5 environment, Knox will help Reach Security significantly reduce compliance timelines and costs and provide agencies with a solution that delivers the speed, visibility, and automation needed to stay ahead of modern adversaries.
"Every network in the Department of War is layered with identity, endpoint, email, firewall, and SASE defenses, and each one is only as strong as its configuration," said Irina Denisenko, CEO of Knox Systems. "By clearing Reach Security's path to IL5, Knox is helping defense security teams get a continuously validated view of whether their controls are doing what policy requires, inside the boundary where their most sensitive unclassified workloads live."
