So, you've just installed SentinelOne and your devs are already screaming that their custom build scripts are getting slaughtered. Welcome to the club. The coffee machine is over there, but it's been flagged as a potential threat. 😂
In my experience, the out-of-the-box policies, especially the **Execution Control** and **Script Control** modules, are set to "paranoid ex-bouncer" mode. That's not *entirely* a bad thing. For a fresh deployment, starting locked down and carving out exceptions is the right security posture. But if you just slap it on a developer workstation or a CI/CD runner without tuning, you'll grind productivity to a halt. I've seen it kill `npm run` scripts, Python virtual environment activators, and even certain `docker build` steps because they exhibit "script-like" behavior.
The real question is: what's your environment? For a hardened production fleet? The defaults are a decent starting point. For developer machines or build servers, you need to immediately look at creating a separate policy group. Here's a taste of what your exclusion list might start looking like:
```yaml
# s1_exclusions_sample.yaml
# Paths for CI/CD runners
- /var/lib/jenkins/**/*
- /opt/buildagent/work/**/*
# Tools
- **/node_modules/**/*
- **/venv/**/*
# Process names (be careful here!)
- python3
- node
- go
- make
```
The pain point is the learning curve. The console will light up like a Christmas tree for the first 72 hours. Your job is to sift through those "malicious behavior" alerts and decide: is this actually malicious, or is it just Frank's weird legacy deployment script? The brutality of the defaults forces you to do this inventory, which is honestly valuable.
So, are they too aggressive? For securing assets, no. For enabling developers, yes—out of the box. The key is to use the aggression to your advantage, then dial it back strategically with exclusions and custom policy rules. Skip that step, and you'll have a mutiny on your hands.
