Alright, let’s set the scene. We were running one of those “legacy” AV platforms—you know the type, the one that basically just checks a box for compliance and sends you a green “all clear” report every morning. Felt like paying for a guard dog that sleeps through the burglary.
Switched to SentinelOne a few months back. Rollout was… fine. The real kicker wasn't the platform itself, but what it started digging up.
We went from maybe one or two "incidents" a quarter (usually just a weird tool our devs built) to a steady drip of actual, no-kidding threats. I'm talking:
* Credential dumpers living in temp folders for *months* that the old AV never peeped about.
* Legit, signed software (think: obscure PDF converters, driver updaters) acting as loaders for coin miners.
* A handful of compromised user accounts where the initial beacon was caught, but the follow-on lateral movement attempts were the real gold. Old system would have seen the first callout, maybe, and then gone blind.
The scariest part? The volume. It's not that we're being targeted by APTs daily, but the background noise of automated, low-sophistication attacks that were just… sailing through before. It’s like we upgraded from a blurry security camera to 4K with motion tracking, and suddenly you see all the rats in the alley.
Anyone else make a similar jump and get that sobering "oh, we've been living with our doors unlocked" feeling? I'm curious how other EDR/XDR platforms compare on this initial "uncovering" phase. Is it just that any modern EDR will show you how bad your legacy AV was, or did we pick a particularly good bloodhound?
