DISA’s Thunderdome prototype represents a major shift in the Department of Defense’s cybersecurity strategy by replacing legacy systems with a modern Zero Trust architecture built on SASE and SD-WAN. Designed to improve security, performance, and interoperability, Thunderdome serves as a scalable, unified network solution that supports both classified and unclassified environments while enabling secure, seamless access for users and mission partners. Versa Networks plays a key role in the initiative by delivering integrated SD-WAN, Zero Trust Edge, and unified management capabilities critical to Thunderdome’s success.
