One operating team. Four disciplines.

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.

Selected engagements

Work across sectors where downtime isn't an option.

Representative engagements. Client names withheld per confidentiality terms — references available on request.

Case · Healthcare

Regional public health plan

Partnered with executive leadership to assess cybersecurity maturity and build a security roadmap for one of the nation's largest publicly operated health plans. Designed and implemented Zero Trust access controls to secure PHI across 5,000+ staff during rapid organizational change.

Major metropolitan transit authority

Emerging platforms

Tools we're building from the work.

Each started as a problem we saw repeatedly across client engagements. They're in active development — not packaged products — and they inform our services practice as much as the other way around.

Sensus

AI intelligence & analysis

Synthesizes signals across operational, security, and strategic data — helping leaders see around corners faster than a dashboard allows.

Vigil

Managed detection & response

Continuous monitoring and response delivered by analysts with intelligence-community and enterprise security backgrounds.

Arcana

Threat & data intelligence

Curated threat intelligence contextualized for the decisions our clients actually make. Sector-specific briefings, not raw feeds.

What our clients say

Referred, retained, and re-engaged.

Colossus brought a level of rigor to our security program I hadn't seen outside of my time in government. The team understands the difference between compliance theater and real operational security — and they delivered the latter.

VP Infrastructure
Healthcare operator

We've worked with four staffing firms over the last five years. Colossus is the only one whose candidates consistently show up ready to do the work on day one. The difference is that their recruiters actually understand the roles.

Director of Engineering
Technology firm

Their AI governance work was the first time we got a framework that was actually usable by the product teams it applied to. Not a policy document nobody reads — real guardrails that moved faster than our lawyers expected.

Representative quotes from client engagements. Names withheld per confidentiality terms.

Resources

Field notes, from the work itself.

Long-form thinking on cybersecurity, AI governance, privacy engineering, and technical hiring — drawn from live engagements.

More pieces in development. Full library expands monthly.
