The Defense Information Systems Agency (DISA) last Friday said it has awarded Booz Allen Hamilton [BAH] a potential five-year $1.9 billion other transaction authority agreement (OTA) for Thundersome, which will allow Defense Department agencies and military departments to acquire zero-trust security technology at scale.

Thunderdome is DISA’s zero-trust network access and application security architecture. The OTA is structured like an indefinite-delivery, indefinite-quantity contract.

“Awarding this Thunderdome production agreement is an important step on our zero-trust journey and furthers DISA’s mission to provide warfighters with a more secure operating environment,” Air Force Lt. Gen. Robert Skinner, the agency’s director and Joint Force Headquarters-Department of Defense Information Network Commander, said in a statement. “While DISA leverages these capabilities on our cyber terrain, this full-scale production agreement can be used to assist the military services and other DoD components in implementing key zero-trust activities.”

The award follows a successful 18-month effort by Booz Allen that DISA used to implement a prototype solution. The Thunderdome prototype ended earlier this year and showed that commercial technologies such as secure access service edge, software defined-wide area networks, customer edge security stack, and application security stacks, can improve security and network performance in an existing enterprise environment, DISA previously said.
