What ATX Defense does
ATX Defense is a veteran-owned consulting firm headquartered in Austin, Texas, that delivers cybersecurity compliance and digital transformation services to the U.S. Department of Defense (DoD) and Defense Industrial Base (DIB) contractors. The company's flagship product, CMMC Space, is a FedRAMP Moderate Equivalent Virtual Desktop Infrastructure (VDI) solution built on Google Workspace and operating within Google Cloud's FedRAMP High environment. The platform is pre-configured with CISA baselines, a secure Chrome browser, and mission-specific virtual machines, and addresses 307 of the 320 NIST 800-171 assessment objectives required for Cybersecurity Maturity Model Certification (CMMC) Level 2. ATX Defense is also an authorized Certified Third-Party Assessment Organization (C3PAO) under the Cyber AB, making it the first and only Google Partner to hold both CMMC Managed Service Provider (MSP) status and C3PAO authorization.
The business model combines a subscription SaaS product (CMMC Space, $299/user/month with a 5-user minimum), an ITAR compliance add-on ($30-$36/user/month), fixed-price C3PAO assessment engagements, and ancillary DoD digital transformation services. Pricing is publicly disclosed with transparent tiers, positioning CMMC Space at roughly an order of magnitude below the cost of a comparable Microsoft GCC High VDI deployment. Distribution runs through direct sales via atxdefense.com and cmmcspace.us, the Army's $49 million five-year NCODE contract vehicle, a separate Defense Innovation Unit (DIU) contract, and federal acquisition pathways including GSA MAS and OASIS+. Customer segments split between small and mid-sized defense contractors (primary, handling CUI and pursuing Level 2 certification ahead of the November 10 deadline) and DoD program offices (Army Software Factory, Marine Corps Software Factory) for digital transformation engagements.
The platform is in use by more than 300 organizations, with 70+ defense contractors certified to CMMC Level 2. ATX Defense operates as a Service Disabled Veteran Owned Small Business (SDVOSB) with reported headcount of 1-10; co-founders Zach Walker (formerly of NSA, CIA, DIU, and the Pentagon; Federal 100 honoree) and Shawn Kotoske lead the firm. The company debuted at #1779 on the 2025 Inc. 5000 list with a three-year growth rate above 245%, and CMMC Space achieved FedRAMP Moderate Equivalent certification via independent 3PAO assessment in January 2026.
