Built for how Fairfield County works
The county's business mix — investment firms in Greenwich and Stamford, professional practices, and growing operators along the Metro-North line — needs two things from IT: security that satisfies sophisticated counterparties, and discretion. Our financial practice serves hedge funds and CPA firms under confidentiality we extend to our marketing: no client names, no borrowed logos. For firms that need a security executive without the salary, our vCISO program covers strategy, policies, insurance readiness, vendor risk, and board reporting.
A real footprint, described honestly
We won't pretend to have a Greenwich office — our headquarters is in Brooklyn, and Fairfield County is on-site coverage territory, reached the same way we cover the rest of the tri-state area. What's concretely here today: a multi-location client with an Old Greenwich location, the same operator whose Westchester work is quoted on our Westchester page, plus the financial-firm engagements we keep confidential.
Who this fits
Hedge funds and investment advisers needing vCISO leadership and questionnaire-ready security; CPA and professional firms protecting client financial data; and any Fairfield County business that wants engineers who show up, month-to-month terms, and a security-first stack — MFA, EDR, email protection, tested backups — behind everything.
