What you get with a firm our size
No account managers and no bench. You deal with the people responsible for the result.
Practitioner-led delivery
The CISSP-certified engineer who scopes the work is the one who performs it, with no handoff to junior staff.
Authorization experience from the inside
Our CTO has served as ISSO and ISSE on DoD systems, so deliverables arrive in the form assessors and authorizing officials expect.
Acquisition literacy
Our CEO has administered procurement records under FAR and DFARS, which keeps our proposals, invoicing, and documentation compliant.
Credentialed principals
Credentials include CISSP, CompTIA Security+, and graduate study in cybersecurity risk management and artificial intelligence.
Local and right-sized
Based in Hampton Roads near the region's Navy and defense installations, and structured for simplified acquisitions and subcontract roles under prime contractors.
