Our vision

At Critical Start, we are redefining Managed Detection and Response (MDR) to set a new standard in cybersecurity. Our mission is to minimize the likelihood and impact of breaches while empowering organizations to maintain business continuity. Guided by our Cyber Operations Risk & Response™ (CORR) platform, we deliver human-driven, AI-assisted threat detection and response, ensuring unmatched visibility and Complete Signal Coverage. By integrating proactive safeguards and tailored response actions, we enable businesses to strengthen their security posture, reduce risk, and thrive in an ever-changing threat landscape.

SCOTT FUNK

I would say that prior to the relationship with Critical Start, my SOC analysts were experiencing what we all call alert fatigue. Critical Start has really been able to reduce those alerts… I’ve been able to take our level three and four analysts and put them back to work at what they were hired to do.
