FirstSoft

A fintech handling regulated data

We re-architected a permissive internal platform into a zero-trust system — every request authenticated, authorized, and audited, with least-privilege access by default.

The problem

A single stolen credential could reach far more than it should — broad implicit trust, thin audit trails, and access rules nobody could fully explain or prove to an auditor.

  1. 01

    We replaced implicit trust with explicit policy: every request proves its identity and is granted only the access it needs.

  2. 02

    We scoped each service to least privilege and made every access decision auditable, so who-can-do-what is always answerable.

  3. 03

    We wired security scanning and policy checks into CI, so regressions are caught before they ship, not after.

The outcome

A platform where one compromised credential no longer opens the whole system — a tighter blast radius, clean audit trails, and access the team can actually reason about.

One senior team, end to end. Tell us what you're building and we'll architect the path to ship it.
