Colossus is a professional services & staffing firm with deep roots in intelligence, defense, and enterprise cybersecurity. We advise, assess, and engineer programs across critical verticals including Healthcare, AI, Government, and Manufacturing.
Most firms ask you to choose between an advisory partner and a staffing partner — between thinking and doing. We don't. Engagements move between disciplines as your needs evolve, on one contract and one accountability line.
Cleared and commercial technical talent, placed by recruiters who have operated the roles they fill. Direct-hire, contract, and contract-to-hire engagement models.
Assessments, security engineering, managed detection & response, and incident response — aligned to NIST CSF 2.0, CIS v8, HIPAA, and CMMC.
AI readiness assessments, foundation-model integration, agentic systems, and platform modernization. From pilot to production.
Privacy engineering, WISP & 201 CMR 17.00 compliance, HIPAA programs, AI governance frameworks, and GRC program maturity.
Representative engagements. Client names withheld per confidentiality terms — references available on request.
