SigilArk

SigilArk is a WOSB-certified technology company focused on deploying AI within classified federal and defense environments. Rather than relying on public APIs, it runs open-weight models and agent teams inside customers’ IL4, IL5, and IL6 boundaries, with air-gapped options, hardened infrastructure, and auditable activity designed to support authorization and compliance. Its services combine AI-first engineering with program operations, cybersecurity, and RMF documentation, helping government teams build and deliver software under ATO requirements.

The company’s flagship product, Glyphon, coordinates AI agents for tasks such as vulnerability remediation, code security, system hardening, and eMASS documentation, with human oversight and a structured audit trail. Affirmark supports small and midsize DoD subcontractors with CMMC Level 1 self-attestation workflows, evidence management, and continuous control monitoring; it can also support Level 2 requirements. Both products are deployed within the customer’s environment. SigilArk also offers Colophon, an AI-first engineering bench, and Vallark, a mobile ATO compliance capability. Its delivery work includes air-gapped AI deployments, secure software development, and authorization-ready compliance tooling for federal programs.
