Who we serve

For financial firms where the logic is the attack surface.

In financial software the expensive bugs are rarely exotic. They are a transfer that can be replayed, a limit that is checked once, an approval step that can be skipped. We test for those first, and map the results to the frameworks your examiners and partners already use.

What we usually find

Where money moves, logic breaks.

01 Race conditions Two simultaneous requests that both pass a balance or limit check before either is recorded.
02 Skippable workflow steps Approval, verification or KYC steps enforced by the order of screens rather than by the server.
03 Rounding and precision Currency handled as floating point, so a thousand tiny transactions add up to real money.
04 Third-party exposure Aggregators, card processors and open-banking connections holding more access than the integration needs.
Frameworks this sector answers to

NIST CSF 2.0, PCI DSS v4.0.1 and SOC 2 — with the CIS Controls v8.1 for the infrastructure underneath.

Representative engagement. Client names, figures and identifying details are changed or combined; no client findings are published in identifiable form.
