Critical Start

Managed detection and response pairing human analysts with AI-assisted alert triage.

Critical Start runs a 24x7 MDR service in which analysts investigate alerts from a customer's endpoint, SIEM, and identity tools, with AI used to speed triage. Customers can see the same evidence the SOC sees, and response commitments are contractually defined. Founded in 2012, the company serves mid-market and enterprise clients.
