Case Study: Sera-Brynn achieves rapid threat detection and full network visibility with LogRhythm Network Monitor

Portable Network Forensics Empower Threat Detection and Incident Response

Sera-Brynn is a global top‑10 cybersecurity audit and advisory firm that provides penetration testing, incident response, post‑breach forensics and security consulting for clients across industries and governments. Their challenge was turning vast, complex network traffic into actionable intelligence in the field: manual and open‑source approaches were slow, error‑prone and hard to deploy quickly during time‑sensitive breach investigations, so they needed a portable, easy‑to‑use network forensics and analytics solution.

Sera‑Brynn deployed LogRhythm Network Monitor on portable Intel NUCs to provide full packet capture, deep visibility, passive/stealthy collection and powerful GUI/Elasticsearch search capabilities. The tool enabled rapid triage and investigation, uncovered hidden secondary compromises (for example, Zeus introduced via BitTorrent/Tor), helped contain a long‑running defense contractor breach within days, and significantly reduced investigation time while becoming part of the firm’s standard incident‑response kit.
