Full-Scale Security Audit & Penetration Testing

Our Approach

1. 1

   Reviewed LondonFin’s existing security policies, incident response playbooks, and architecture diagrams.

2. 2

   Conducted automated SAST/DAST scans across 12 microservices and a manual code review of authentication and payment flows.

3. 3

   Executed simulated attacks: SQL injection, XSS, CSRF, SSRF, and API fuzzing against staging and production-like environments.

4. 4

   Compiled a risk-rated findings report with CVSS scores and recommended remediation timelines.

5. 5

   Delivered a remediation workshop and re-tested all critical and high-severity findings within 30 days.

The Solution

We conducted a full-scope security audit spanning web application, API, and infrastructure layers. Our team identified 23 vulnerabilities (3 critical, 8 high, 7 medium, 5 low). Critical findings included an insecure direct object reference (IDOR) in the payment API and a misconfigured AWS S3 bucket exposing transaction logs. LondonFin remediated all critical and high-severity issues within two weeks. We re-tested and issued a clean security report that satisfied FCA requirements.

Client Testimonial

The depth of the WebCEO team’s analysis was outstanding. They found issues our own security team had missed for months, and the remediation workshop made fixing them straightforward.
