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.
