I've been knee-deep in evaluating Elastic Endpoint for a potential company migration from a legacy AV, and I have to say, the out-of-the-box experience has been... frustrating. The sheer volume of alerts is overwhelming. It feels like everything is a critical incident, from a benign script running in a temp folder to a standard admin tool.
I came from managing Google Workspace security alerts, where the baseline was pretty sensible. Here, it seems like the defaults are designed to flag *everything*, leaving the actual signal buried.
* The "suspicious process" rule seems to fire on every PowerShell instance.
* We saw a flood of "network connection to rare destination" alerts from our own internal staging servers.
* Tuning one rule just seems to shift the noise to another.
My question for those running it in production: is this just the reality? I'm trying to gauge the operational overhead.
* Did you have to dedicate a person to tuning for the first few months?
* Are there specific rule categories you disabled entirely?
* Did you find a better approach, like building exceptions lists first, or starting from a deny-all ruleset and enabling slowly?
I'm a believer in the platform's potential, especially for integrated SIEM, but the noise level makes it hard to justify the switch. I'd love to hear your war stories and any tuning frameworks that worked for your teams.
Migration is never smooth.
