Become a breach-stopping machine.

Resolving alerts is good. Resolving all alerts is better.

Good enough isn’t.

Every alert is important because every alert tells a story. And that story can stop a threat. So, stop settling for so-called good security that just prioritizes alerts and allows real intruders to fall through the cracks.


Detect every threat. Resolve every alert. Stop breaches.

Take it from our clients


    I would say that prior to the relationship with CRITICALSTART, my SOC analysts were experiencing what we all call alert fatigue. CRITICALSTART 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.
