CIS Secure Computing

What CIS Secure Computing does

CIS Secure Computing (legal entity CIS Maxwell, LLC) is a privately held secure communications and cybersecurity solutions provider headquartered in Ashburn, Virginia, founded in 1992 and operating with 101-250 employees. The company designs, integrates, and supports an end-to-end portfolio of secure communications products for the U.S. defense, intelligence, homeland security, and Department of Energy communities. Its core hardware products include the TEMPEST Portable High Density Server Kit (HDSERV) for tactical edge computing, the Secure Personal Mobility Platform, the TSG Approved Poly CCX 600 VOIP Phone, and TSG USB Positive Disconnects for physical data isolation. These are supported by the proprietary altOS mobile cybersecurity platform and service categories spanning Secure Collaboration (TSG voice/video), Mobile Mission Support, Secure Edge/TEMPEST solutions, and Secure Services including Counter-UAS capabilities.

The company's revenue model is built on three streams: hardware sales of TEMPEST-certified and TSG-compliant equipment, professional services (engineering, integration, program management, intelligence analysis, mission support), and managed services delivered through MSSP partnerships including CMMC compliance support. Pricing is quote-based under multi-year government contracts, with distribution via direct enterprise sales, government contract vehicles, and select technology integration partners (notably Poly). CIS Secure holds rare regulatory accreditations including NSA Certified TEMPEST manufacturer and test facility status, CMMC Level 2 certification with a perfect score of 110, and ISO 9001, which collectively create high barriers to entry in the classified communications market. The company is backed by The Riverside Company (minority investment, April 2021) and Bluestone Investment Partners, acquired Intrepid Solutions and Services in August 2022, and appointed Joe Adams as CEO in January 2026 to lead next-stage growth.

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• L3Harris Technologies: L3Harris provides secure tactical communications, encryption, and mission systems for DoD/IC customers. It overlaps directly with CIS Secure's TEMPEST, TSG, and secure collaboration offerings but is a vastly larger incumbent that often primes programs CIS would participate in as a subcontractor.
• CACI International: CACI delivers secure communications, IT, and intelligence services to DoD and IC customers. Its federal secure communications and integration work overlaps with CIS Secure's TSG, TEMPEST, and mission support capabilities, though at significantly larger scale.
• Parsons Corporation: Parsons provides defense and intelligence services including mission solutions, cyber, and secure communications support to DoD/IC customers. Its services-plus-technology model and intelligence community footprint overlap with CIS Secure's integrated offering post-Intrepid acquisition.
• General Dynamics Mission Systems: GDMS is a major defense prime delivering secure communications, cryptography, and tactical networking solutions across the DoD and IC. It competes with CIS Secure at the program-of-record level for classified voice/video and tactical comms, but at a much larger scale and broader portfolio.
• Leidos: Leidos provides defense, intelligence, and homeland security solutions including secure communications systems and integration services. It competes for many of the same federal programs CIS Secure targets, with a much broader portfolio and prime contractor role.

Direct peers

• Curtiss-Wright Defense Solutions: Curtiss-Wright supplies rugged, secure tactical computing and network communications hardware for defense applications, closely analogous to CIS Secure's HDSERV portable server and secure mobility products. It serves overlapping DoD and intelligence customers with similar high-assurance hardware offerings.
• Sierra Nevada Corporation: Sierra Nevada delivers integrated mission solutions including secure communications, electronic warfare, and ISR systems for DoD and IC customers. Its portfolio of secure communications hardware and integration services closely parallels CIS Secure's TEMPEST and mission support offerings.
• Mercury Systems: Mercury Systems builds mission-critical, secure processing hardware for defense and intelligence platforms. It is comparable to CIS Secure in providing trusted, high-performance hardware for classified and tactical environments, though at a larger scale and broader technology base.
• ManTech International: ManTech provides mission-focused secure IT, cyber, and intelligence analysis services to DoD, IC, and federal civilian customers. Its services-and-integration model mirrors CIS Secure's combined hardware plus mission support delivery, particularly post the Intrepid Solutions acquisition.

Emerging players

• BlackBerry Government Solutions: BlackBerry's government-focused secure mobile communications and endpoint security products directly overlap with CIS Secure's altOS mobile cybersecurity platform and Secure Personal Mobility offering. It competes for the same DoD and federal mobile security procurements.
