Questions
What is Critical Start's Trusted Behavior Registry (TBR)?
The Trusted Behavior Registry is a purpose-built component of Critical Start's Zero-Trust Analytics Platform (ZTAP). It eliminates false positives at scale by cataloging known-good behaviors and automatically resolving alerts that match those patterns. This allows Critical Start to resolve every alert — not just the high-severity ones — reducing the volume of escalated alerts to less than 0.01% and ensuring no alert is ignored or left uninvestigated.
Does Critical Start require a specific EDR or SIEM?
No. Critical Start takes a vendor-agnostic approach, integrating with major EDR platforms (CrowdStrike, SentinelOne, Microsoft Defender, Palo Alto Cortex XDR, Carbon Black, Cylance) and SIEM solutions (Microsoft Sentinel, Splunk, Sumo Logic). With over 100 log source integrations and direct APIs, organizations can keep their existing security investments.
What is MOBILESOC?
MOBILESOC is Critical Start's proprietary mobile application for iOS and Android that gives security leaders full alert triage, threat containment, and direct SOC analyst communication from their phone. It provides the same visibility analysts see — including alert timelines, actions taken, and real-time push notifications — enabling incident response without requiring desktop access.
