Critical Start was able to get operational and effective across many thousands of devices on multiple continents in a short amount of time and provides pretty excellent coverage. They were also fairly agnostic as to the endpoint client and were able to accommodate different EDRs simultaneously. We have used them for many years and have never been disappointed. We regularly test their detection capabilities, and they are able to accommodate our own custom detections without difficulty. Their MTTD & MTTR are fairly consistent and always well above industry standards. The phone app is feature-rich and comes in handy more often than you would think.
