SOLUTIONS / FINANCIAL SERVICES & FINTECH

Web security built for the sector where downtime means regulatory events.

Financial services organisations face the most demanding combination of attack volume, compliance pressure, and operational expectation. CrownWall is configured for all three.

Secure transaction flow

Authenticate → Inspect → Route → Protect

Abstract representation of a secure application flow with layered protection, low latency, and end-to-end evidence.

The financial sector is the most targeted. For good reason.

Fintechs and financial services organisations are targeted by both opportunistic attackers and organised groups. The threats are familiar — credential stuffing against customer login portals, card-testing attacks against payment APIs, transaction manipulation attempts — but the consequence of failure is amplified.

Lost funds, regulatory escalation, mandatory notification, and customer trust erosion arrive simultaneously.

High pressure, low tolerance for failure.

When downtime or abuse reaches regulated payment flows, the incident becomes technical, operational, legal, and reputational all at once.

Every layer, mapped to your compliance obligations.

Controls designed for payment flows, regulated workloads, and evidence-heavy reviews.

WAF + PCI-DSS v4

CrownWall's WAF satisfies PCI-DSS Requirement 6.4.2 with exportable evidence for QSA review — coverage reports, rule audit trails, and incident logs formatted for assessors, not engineers.

API protection for transaction endpoints

Granular L7 rate limiting at the endpoint level prevents card-testing, BIN enumeration, and high-volume API abuse against payment flows. Per-key and per-session limits — not blunt per-IP throttling.

Credential stuffing defence

Bot control tuned for authentication endpoints. Challenge options for high-risk login patterns without friction for legitimate customers.

Incident logging for regulatory reporting

Structured logs matching the categorisation frameworks regulators and insurers expect. Full request/response correlation for forensic reconstruction.

Data residency

Deploy in the jurisdiction your regulatory framework requires. EU, UK, North America, and APAC available — with explicit data location commitments in the contract.
