Hey everyone, I've been tasked with looking after our SentinelOne deployment for the last two years. We're a mid-size shop, and I came from a more general sysadmin role, so this EDR world has been a learning curve!
After 24 months, I have some mixed feelings. On the love side, the automated rollback and remediation is fantastic for us beginners—it just *stops* things and tells us what it did. The threat hunting stories feature also feels like guided learning, which helps a lot.
But the things we struggle with... the console can feel overwhelming with alerts sometimes. Tuning it without creating blind spots is tricky. Also, the cost creep year-over-year was a surprise for management.
For those of you with more experience, especially at scale: how do you handle alert fatigue with S1? And any tips for justifying the cost in renewals? 😅
Oh man, that alert fatigue point is real. The console is a firehose. What worked for us was going hard on custom exclusions and policies, but you're right - it's a tightrope walk. We created a "noisy but harmless" policy group for dev machines that gets more exclusions and less aggressive scripting blocks, while servers are locked down tight.
For cost justification, I built a simple CI pipeline that runs a compliance check. It pulls our S1 agent health stats and open critical alerts via API, then slaps it into a weekly report. Showing management a graph of automated remediations vs. manual analyst hours saved usually shuts down the cost talk. It's about shifting the conversation from "cost of tool" to "cost of incident without it."
pipeline all the things
I felt the same way about the console at first. The guided stories are great, but the jump from that to the raw alert dashboard is huge.
For the cost part, I've found it helps to track the stuff that *doesn't* happen. We logged a few near-misses from phishing where S1 killed the process before it could even call home. Putting a dollar figure on a potential ransomware cleanup versus the license cost made the renewal much easier for us.
How granular have you gotten with your policies? We started with just one, but I'm thinking we need to split ours up like user200 mentioned.
Totally feel you on the cost creep surprise - that's practically a feature with these platforms. Management's eyes glaze over when you talk about "threat surface," but they understand unexpected invoices.
For renewal justification, I'd pair user200's idea with some hard numbers from your own environment. Use the S1 APIs to pull automated remediation counts and map them to a rough "analyst hours saved" figure. I've seen shops use a conservative $150/hour for a tier 2 analyst. If S1 auto-fixed 50 incidents last quarter that's... well, you do the math, but it usually dwarfs the license fee. Makes the conversation about ROI, not cost.
The alert fatigue is a tougher beast. We leaned heavily into policy groups - not just dev vs. prod, but web servers, CI/CD runners, and finance workstations all got their own. The initial setup is a pain, but it lets you be surgical with exclusions and scripting rules. Turns down the noise where you can afford to.
That's such a good idea about the separate policy for dev machines. I get so scared of making changes, worried I'll break something. Splitting them out like that, where it's okay if dev is a bit noisier, makes a lot of sense.
Your CI pipeline trick for reporting is brilliant. I'm still trying to get comfortable with the API myself. Was it tough to set up? I mostly use GA's API, so this feels...scarier for some reason 😅
