Both overpriced. But since you're asking about detection rates, you're already asking the wrong question.
Detection rates on vendor slides are useless. They run curated malware zoo tests in a lab. Real work is about:
* Process tree visibility
* IO pattern capture during encryption bursts
* Telemetry noise that drowns your actual alert queue
Switched our 2000-node fleet off SentinelOne last quarter. Not because it missed things, but because:
* Resource overhead was inconsistent. Quiet one day, 40% CPU on an idle Jenkins agent the next.
* Their scripting engine "deep visibility" logs are a mess to parse. Try extracting a meaningful timeline from this JSON blob:
```json
{"event_type":"script","details":{"script_block":"...obfuscated garbage...","interpreter":"powershell","parent_image":"c:\windows\system32\svchost.exe"}}
```
CrowdStrike's query language is marginally better. But now you're just trading one dashboard for another.
Better question: which one lets you build actionable alerts without a PhD in their proprietary query syntax? Answer: neither. Write your own canary tokens and log the rest.

Senior SRE at a 600-node fintech shop. We run both, SentinelOne on workstations, CrowdStrike on servers, because our security team couldn't decide.
Detection rates in production: Don't care. Both catch the noisy stuff and miss the quiet, tailored attacks. The real metric is mean time to verdict from your SOC. CrowdStrike's UI is faster for triage once you learn it.
Resource tax: SentinelOne's variance is real. Saw 15-18% CPU on a quiet API box, spiked to 60% during a yum update. CrowdStrike sits at a boring 3-5% consistently. Memory is a different story - CrowdStrike chews 200-300MB per host, SentinelOne about half that.
Deployment pain: CrowdStrike's RPM/deb is clean. SentinelOne's installer had a habit of leaving zombie processes on RHEL 8 if you didn't use their exact uninstall script first. Took a day to clean up 30 failed rollouts.
Cost reality: We pay ~$7/endpoint/mo for CrowdStrike (Falcon Prevent). SentinelOne was ~$5.50. But CrowdStrike nickel-and-dimes for modules like Identity Protection. The real cost is engineering hours to build dashboards that filter their alert spam.
If you're ops-focused and just need a silent, stable sensor that won't blow up your monitoring, CrowdStrike. If you're building custom detections and can tolerate performance quirks, SentinelOne's data is richer. Tell us your team size and if you have a dedicated SOC.
If it ain't broke, don't 'upgrade' it.
> Detection rates on vendor slides are useless.
Agree completely. The slides are marketing. Your point about telemetry noise drowning the queue is the real operational cost.
CPU variance on idle systems you described tracks with what we've seen in our logs. It's a scheduler issue, not a detection one. Tells you more about their quality control than their threat intel.
I'd add that "actionable alerts" often means writing custom logic to filter out their own platform's background noise. You end up building a parser to clean their parser's output. Defeats the point.
Beep boop. Show me the data.
