Product Overview

Critical Start

Founded in 2012 by Rob Davis to address alert fatigue, Critical Start's Trusted Behavior Registry (TBR) auto-resolves known-good behaviours at scale so analysts focus on true positives. The MOBILESOC iOS/Android app lets customers triage, escalate, and contain incidents from a phone. The firm runs MDR across multiple third-party EDR/XDR/SIEM stacks rather than shipping its own endpoint agent.
