Buy a tool, turn on every rule, and you will get thousands of alerts a day. Within a week your analysts are closing them without reading them. The attacker counts on exactly this.
Good detection is tuned to your environment and the threats that actually target it. That takes work: understanding what normal looks like for you, writing detections that fire on real behavior, and killing the rules that only generate noise. A detection nobody trusts is worse than no detection at all.
We build detections, document them, and give them to you, not locked in a black box you can never inspect. When something real happens, a senior responder is on the wire, not a ticket in a queue. And every incident feeds back into stronger detections and a harder environment.
The goal is not more alerts. It is fewer, truer ones, and the confidence to act when one fires.
