Case Study: Brewin Dolphin achieves improved security visibility and faster incident resolution with ExtraHop

Brewin Dolphin Improves Security Visibility and Control with ExtraHop

Brewin Dolphin, a UK wealth manager founded in 1762 and listed on the FTSE 250, undertook a multi-year network refresh and cloud adoption across 40+ locations that revealed gaps in visibility for its Network and Security teams. The firm’s Digital Security & Resilience team needed a monitoring solution to provide comprehensive, contextual insight across an evolving technology environment.

After evaluating options, Brewin Dolphin selected ExtraHop for full‑stream analysis, traffic decryption, and machine‑learning–driven detections that surface meaningful events with low false positives. Deployed across the organisation and integrated with the SIEM, ExtraHop immediately exposed previously unseen activity (including a penetration test), helped resolve obscure domain‑controller drops, and delivered richer, cross‑team data that accelerated troubleshooting and improved operational effectiveness.
