SOLUTIONS / FINANCIAL SERVICES & FINTECH

Protection and evidence for regulated finance.

Financial services organisations face high attack volume, strict compliance expectations, and zero tolerance for payment-flow downtime. CrownWall maps platform capabilities to the threats and evidence requirements common in regulated finance.

Sector threats

Finance and fintech applications are targeted through customer login portals, payment APIs, low-and-slow floods, and classic OWASP attacks against both web and API surfaces.

Finance risk profile

Credential stuffing

Automated login using leaked credentials.

Card testing

High-volume API abuse against payment endpoints.

L7 DDoS

Low-and-slow floods on login and transfer paths.

OWASP Top 10

SQLi, XSS and sensitive-data exposure.

Credential stuffing

Automated login against customer portals using leaked credentials.

Card testing & BIN enumeration

High-volume API abuse against payment and transaction endpoints.

Application-layer DDoS

Low-and-slow floods targeting login, transfer, and checkout paths.

OWASP Top 10 attacks

SQL injection, XSS, and sensitive-data exposure against web and API surfaces.

Recommended capabilities

Controls for payment and web application protection, transaction API abuse, credential stuffing, edge DDoS, resilient delivery, and assessor-ready evidence.

WAF for payment and web applications

Every hostname gets a dedicated Web ACL with managed OWASP Top 10 rule packs (SQL injection, XSS, sensitive data exposure) and custom rules for admin paths, API key requirements, and IP/CIDR policies.

Request and response inspection blocks attacks at ingress and catches error disclosures and data leaks in responses before they reach users.
Request normalization neutralises encoded and obfuscated payloads before rule evaluation.

See: Web application firewall

API protection for transaction endpoints

Protect payment and account APIs with limits that match real abuse patterns — not blunt per-IP throttles alone:

Per IP + URL path — cap POST to /api/login or /api/payment independently of other traffic.
Composite keys — mix IP, path, HTTP method, and named headers such as an API key header.
Custom rules — require API key headers on machine-to-machine endpoints.
Upstream signals — forward WAF disposition and verification status to your application layer.

See: API security

Credential stuffing defence

The managed bot control pack classifies credential-stuffing automation, CLI clients, and headless browsers. Apply challenge or proof-of-work captcha on authentication endpoints without blocking legitimate customers — verified humans receive a time-limited session token.

Allow verified monitoring bots; captcha or block aggressive automation. Labels integrate with WAF policy for stepped-up responses on repeat offenders.

See: Bot management

DDoS and reputation at the edge

Layer 7 rate limits absorb brute-force bursts and HTTP floods. Managed IP reputation labels traffic from suspicious hosting and scraper networks before a flood builds — chain to challenge, captcha, or block downstream.

Attack volume shed at the edge; rate limits scoped per endpoint so other routes stay unaffected.

See: DDoS protection

Delivery without single points of failure

Health-aware load balancing across multiple origins with HTTP, HTTPS, TCP, or gRPC probes. Dynamic DNS origin discovery as infrastructure scales. Request ID on every transaction for forensic correlation across edge and backend logs.

See: Load balancing & delivery

Evidence for assessors and incident response

Structured JSONL access logs capture domain, WAF terminating action, matched rules, security labels, cache status, and Request ID — ship to your SIEM for PCI, SOC 2, and incident investigations. Prometheus metrics and a live dashboard show blocks, challenges, and top matched rules without querying raw logs first.

Policy changes (WAF rules, rate limits, origins) apply on reload — no application redeploy.
