Why this combo
The decisions we made differently — and why they matter for trading specifically.
Cross-account order injection, IDOR on order modification endpoints, race conditions between cancel + fill, signed-payload tampering on order submission. We test these as the highest-severity items because they are.
Spoofed quotes injected via WebSocket, sequence-number gaps that aren't gap-filled, stale-price-presented-as-fresh. If your trader sees a fake quote and acts on it, that's a compliance + financial-loss event in one.
Most retail brokers don't speak FIX directly, but if you have institutional flow or partner-bank settlement, it's there. We audit FIX message integrity, session takeover, replay protection, and the often-poorly-tested administrative messages.
T+1 settlement (US equities) means your money-movement code runs daily on a tight clock. We audit the reconciliation jobs, partner-bank payout endpoints, ACH return handling, and the failure modes when settlement files arrive late or malformed.
A trader keying "10000" instead of "100" is operationally the same risk as an attacker injecting that order. We treat per-order, per-symbol, and per-account size limits as security controls — and we test what happens when they're missing or bypassable.
Executive summary + technical detail + remediation status + retest sign-off, formatted for FINRA / FCA / ASIC / partner-bank vendor reviews. Auditors and risk committees have seen our reports before.

Why Hayaiti
Trading-platform security is uniquely unforgiving: every order is potentially a financial-loss event, every market-data feed is a trust boundary, and every settlement-window slip is a regulatory conversation. The audit playbook covers broker dashboards, order-entry-surface manual testing, and settlement-flow attack tracing end-to-end. We are NOT a registered broker-dealer, NOT FINRA member, NOT a 3PAO — we do the technical engineering layer underneath the regulatory wrapper your compliance officer + counsel built.

Shape of work
A small fintech needed a penetration test ahead of their SOC 2 Type II audit. The win wasn't the report — it was the remediation playbook that gave the engineering team a clear week-by-week path to a clean audit.
Spec engagement built to set the bar — same playbook a real client gets. Real cases publish after launch with the client’s sign-off.
FAQ
It satisfies the technical-pentest portion. The full regulatory examination is broader (governance, supervision, books-and-records); we deliver the part the technical reviewer wants to see. Your compliance officer + outside counsel handle the rest. We've had reports accepted in FINRA exam packages and FCA periodic reviews.
Yes — session-level (logon, sequence reset, heartbeat, resend), message-level (NewOrderSingle integrity, ExecutionReport replay, OrderCancelRequest race conditions), and admin-level (Logon authentication, password rotation enforcement, IP allow-listing). FIX is older protocol territory; we know what to look for.
We test the consumption side: feed authentication, subscription tampering, sequence-number validation, gap-fill correctness, snapshot-vs-incremental reconciliation. We don't pentest the feed source itself (Polygon, IEX, etc. handle their own security); we test how YOUR system handles malformed or hostile data from those sources.
Yes — readiness, not attestation. We map your existing controls to SOC 2 TSC + ISO 27001 Annex A, with extra attention to the financial-services controls (segregation of duties on order-flow code, audit-log integrity for trade reconstruction). Formal certification is by a CPA firm or accredited body.
Same business day notification with reproduction steps and immediate remediation guidance. We don't sit on financial-loss-potential findings overnight — your trading desk gets a written summary while we keep working on the rest of the test.
Yes — mutual NDA + a written authorization-to-test (pen-test rules-of-engagement) before any active testing. We don't run unsanctioned tests against production; the access agreement defines scope, hours, and emergency contacts.
Web + API is in scope by default for the Pentest SKU. Adding the iOS app (or Android) adds scope; we'll quote it separately after kick-off. We do reverse-engineering, certificate pinning bypass, and API replay testing on the mobile clients.
Start with an audit, or jump straight to pricing. Either way, you talk to engineers — not a sales funnel.
