Case Study: Leading UK Financial Firm achieves enhanced cybersecurity and app security with Trustwave Co‑Managed SOC & Penetration Testing

How a Leading UK Financial Firm Strengthened Cybersecurity with Trustwave’s Co-Managed SOC & Penetration Testing

Leading UK Financial Firm, which manages billions in client assets and stores highly sensitive financial data, had relied on a Trustwave Co‑Managed SOC with Splunk as its SIEM since 2017. Despite a skilled in‑house team, the firm lacked 24/7 SIEM monitoring and ongoing fine‑tuning to turn raw alerts into actionable intelligence, limiting its ability to fully realize its SIEM investment and address an expanding threat surface.

Trustwave delivered Co‑Managed SOC services for Splunk, fine‑tuned the SIEM, and rapidly stood up a penetration‑testing program for a new mobile app within two months. Trustwave completed three rounds of testing with iterative remediation guidance, which led the firm to expand testing hours, commission a Red Team engagement (which found no problems), and pursue a Purple Team event — strengthening detection and response, improving SIEM ROI, and measurably hardening protection of client data.
