About Critical Start

Critical Start sells managed detection and response (MDR) that combines AI-powered triage with human-led investigation. The company says tools produce thousands of alerts every day, and that Critical Start MDR works to resolve every one and backs every response time with a contractual SLA.[2][6]

CORR is the MDR platform that Critical Start uses to give a security operations team visibility into every alert, every investigation and every response action. CORR connects to a security stack through native APIs, with no proprietary agents and no forced replacements. Critical Start says CORR connects to an existing stack through API-based integrations, with no agents to deploy, no network architecture changes and no additional infrastructure to manage.[1][4][5]

More than 30 of these are advanced integrations where Critical Start analysts contain threats directly in the customer's tools. Inside the platform, AI agents analyze enriched case data, including URL analysis, suggested verdicts and investigation summaries. A certified SOC analyst validates every finding, with two-person verification on critical alerts. The Trusted Behavior Registry uses deterministic behavioral validation to auto-resolve 99.83% of known-good behaviors before a human analyst sees them.[5]

Critical Start also offers MobileSOC, a native iOS and Android application for real-time security operations management. CORR supports compliance reporting for SOC 2, ISO 27001, PCI DSS, HIPAA, GLBA, CMMC and NERC CIP.

Every managed service follows an Essentials, Enterprise and Signature packaging model. That tier structure applies across MDR for Endpoint, MDR for SIEM and Vulnerability Management Services (VMS).

Every Critical Start managed service contract includes service credits, a prepaid, flexible currency that can be spent across 30+ services. Essentials includes 5 credits, Enterprise includes 10 credits and Signature includes 20 credits per subscription. MDR for Endpoint, MDR for SIEM and VMS each include credits, and credits stack into a single bank when a customer holds more than one.[7]

Critical Start says that in 2012 three security experts who had led incident response and threat hunting at Fortune 500 companies recognized a gap in the market. The company says it protects financial services firms, healthcare systems, manufacturers and utilities across 7 continents. For financial institutions, Critical Start delivers MDR with contractual SLAs and audit-grade investigation documentation.[4][5][6][8]
