Case Study: Gossamer Bio boosts security ops performance 122% and cuts false positives 90% with ReliaQuest GreyMatter

Gossamer Bio Elevates Its Security Operations and Improves Team Performance by 122%

Gossamer Bio, a cloud-first biopharmaceutical company with a lean security team and a zero-trust architecture, was overwhelmed by noisy, redundant alerts from prior providers that limited time for strategic security work. Seeking a partner that could adapt to its cloud-native environment and provide customizable support, Gossamer Bio engaged ReliaQuest and its GreyMatter platform.

ReliaQuest implemented GreyMatter (including the GreyMatter Mobile App) to centralize telemetry, automate investigations, and tune detections to Gossamer’s environment; this reduced false positives by 90%, triaged 77% of alerts, improved security team performance and ticket closure by 122%, cut MTTR from 21 days to 1.8 days (~95% reduction), and increased security posture/coverage by 44%, while enabling better compliance reporting and improved cyber insurance terms.
