What C3 Integrated Solutions does

C3 Integrated Solutions is a privately held, Arlington, Virginia-based managed services provider that designs, implements and operates IT, cybersecurity and CMMC (Cybersecurity Maturity Model Certification) compliance solutions exclusively for the U.S. Defense Industrial Base. The company's flagship is the C3 Suite, anchored by C3 Command, a fully managed CMMC Level 2 compliance program built on a proprietary CMMC Reference Architecture and an 80/20 shared responsibility model in which C3 owns accountability for 234 of 320 assessment objectives. C3 Catalyst delivers the same technical foundation for organizations that retain an external compliance partner, with the CMMC Ready® Program bridging pre-assessment preparation and live assessment support. Adjacent offerings include C3 Core Managed Services, GCC/GCC High and Azure Government deployments, Managed Extended Detection & Response (MxDR), Virtual CISO, and Penetration Testing.

The technical stack is built on Microsoft Government Community Cloud (GCC) High, Azure Government and FedRAMP-authorized cloud services, with C3 operating as one of Microsoft's largest AOS-G partners and one of the first five authorized to sell GCC High licenses. C3 is among the first service providers to achieve dual CMMC Level 2 certification (both MSP and MSSP scopes) following a third-party assessment in February 2025, reinforcing its regulatory positioning. Customer scale includes 150+ defense industry organizations migrated to GCC/GCC High and hundreds of defense contractor clients overall.

The business model combines subscription managed services (C3 Command, C3 Catalyst, C3 Core, MxDR) with professional services engagements (GCC/GCC High deployments, architecture and implementation, vCISO, pen testing), sold through consultative direct enterprise sales with a complementary channel partner program. Pricing is quote-based, varying by environment size, user count and CMMC assessment boundary, and contracts are structured as multi-year engagements. C3 was formed from the 2011-founded C3 Integrated Solutions and the November 2022 merger with Steel Root, and currently operates with a leadership team of roughly 15 C-suite and SVP/VP executives focused on scaling CMMC compliance and managed security services across the DIB.

Core offering

C3 Integrated Solutions is a managed services provider that designs, deploys, and operates IT infrastructure, cybersecurity, and CMMC compliance solutions purpose-built for U.S. defense contractors. Its flagship offering, the C3 Suite, packages a proprietary CMMC Reference Architecture with managed IT, managed security, and compliance advisory services under an 80/20 shared responsibility model to help Defense Industrial Base contractors achieve and maintain CMMC Level 2 compliance.

Product overview

C3 Integrated Solutions operates as a specialized managed services provider delivering a unified portfolio of IT, cybersecurity, and CMMC compliance solutions purpose-built for the U.S. Defense Industrial Base. The company's core offering is the C3 Suite, which comprises two primary managed solutions — C3 Command and C3 Catalyst — both built on C3's proprietary CMMC Reference Architecture. C3 Command is the company's flagship fully managed CMMC compliance program, using an 80/20 shared responsibility model where C3 assumes accountability for 80% of CMMC Level 2 assessment objectives.

The CMMC Ready Program bridges the gap between implementation and assessment readiness for both solutions. Complementing the CMMC Suite, C3 offers C3 Core Managed Services (general DIB IT management without CMMC requirements), GCC/GCC High Deployment, Azure Government Services, IT Architecture & Implementation, Managed Extended Detection & Response (MxDR), Virtual CISO, and Penetration Testing services.
