Case Study: Guardant Health strengthens 24/7 security operations with Exaforce SIEM and MDR

Guardant Health disproves AWS compromise in 15 seconds with Exaforce

Guardant Health, a cancer diagnostics company, faced significant challenges with its previous SIEM. The system required a proprietary query language, forcing constant tradeoffs on log ingestion and leaving critical data like AWS CloudTrail inaccessible. It functioned as a passive, costly log archive with no meaningful detections, and their separate MDR provider delivered shallow, generic investigations that offered little support to their lean security team.

By implementing Exaforce as its primary SIEM and MDR provider, Guardant Health consolidated its security operations onto a single platform. Exaforce ingests all logs, correlates data across the environment in seconds, and uses natural language queries. The solution provides active detections and deep investigative support from the MDR team. Results include disproving a suspected AWS compromise in 15 seconds, reducing mean time to investigate to 12 minutes, and completing work equivalent to 30 people in 90 days through AI agents.
