Fractional technology leadership
Senior technology leadership on your terms. Protect the business, put AI to work, and build cloud foundations that scale.
Services
Technology leadership for startups and scale-ups, across security, privacy, AI, and cloud — engaged the way your business needs it, from a single project to an ongoing fractional role.
Seasoned security leadership on a part-time basis — all the strategy and accountability of a CISO without the cost of a full-time executive hire.
Practical, risk-based guidance to find and fix the gaps that matter most — and to be ready when something goes wrong.
Navigate GDPR, CCPA, and other regulations and frameworks with confidence and speed — and turn compliance into a business advantage.
Put AI to work across your operations — safely. We help you pick the right use cases, set up governance and guardrails, and move from pilots to production.
Securely design, migrate, and manage workloads across leading cloud platforms — with security, resilience, and cost built in from day one.
How it works
Start with a conversation. From there, the engagement is shaped around your stage, your goals, and your team — not a one-size-fits-all program.
A short call about where your company is, where it’s headed, and what’s keeping you up at night.
A focused look at your biggest risks and opportunities. You get a clear shortlist, not a 100-page report.
A practical plan, then hands-on help executing it — either as an embedded fractional leader or on a defined project.
Every interaction with your data, applications, and systems carries risk and opportunity. This is the lens we use to evaluate it — and the “5” in Interaction 5.

Whether you need a fractional CISO, a privacy and compliance roadmap, or a clear plan for putting AI and cloud to work, you’ll get straight answers and a partner who supports you through execution.
Insights
Practical thinking on security, AI, and technology leadership — for the people accountable for both speed and risk.
