Knox Achieves 18th ATO with Tennessee Valley Authority at FedRAMP High

TVA becomes the latest federal agency to authorize the Knox Landing Zone, expanding the reusable path for commercial software and AI companies to serve the U.S. government

WASHINGTON, Sept. 17, 2026 /PRNewswire/ -- Knox Systems ("Knox"), operator of the largest and longest-running Federal and Department of War Managed Cloud, today announced its 18th Authorization to Operate (ATO), with the Tennessee Valley Authority (TVA) authorizing the Knox Landing Zone at the FedRAMP High baseline.

The authorization further expands the Knox Landing Zone: a pre-authorized, hardened cloud environment where commercial SaaS and AI companies can deploy their applications once and inherit an existing government security boundary rather than build, authorize and operate standalone government clouds.

Knox has built its Landing Zone model around a simple premise: government should be able to inherit security rather than repeatedly recreate it. TVA provides technology companies an additional, repeatable path to serve government customers across agencies.

"Government should not have to authorize the same infrastructure over and over again for every piece of commercial software it wants to use. The Knox Landing Zone changes that model," said Hemant Baidwan, Executive CISO of Knox Systems. "TVA marks our 18th ATO and another step toward a future where government agencies can securely access the best commercial technology without every company spending critical resources rebuilding the same federal infrastructure."

About the Knox Landing Zone

With the Knox Landing Zone, commercial applications deploy into an environment that already meets federal security requirements and inherit the underlying security controls, continuous monitoring, infrastructure and operational capabilities maintained by Knox. Agencies can then leverage an established authorization rather than starting the security review from zero for every new application.

The result is a shared security foundation that can support many commercial applications across many government agencies – expanding the number of modern technologies available to government users.

Knox's Landing Zones now span FedRAMP Moderate, FedRAMP High, DISA Impact Level 4 and Impact Level 5, with the company also recently launching the industry's first GovRAMP Accelerator for state and local government.
