Everyone's hyping CrowdStrike and SentinelOne for PCI. GravityZone gets mentioned. But "top" depends on your actual environment, not marketing slides.
PCI requirement 11.5 is about file integrity monitoring. Most EDRs do this. The real test is how they handle the noise in a retail environment. POS systems, legacy inventory apps, constant file changes. You'll get flooded with alerts unless you tune it perfectly. GravityZone's default policies are aggressive. You'll spend your first month in exceptions.
Example: Their FIM rule for `C:WindowsSystem32*.dll` is useless. You need to scope it to your payment application directories, and even then, vendor patches will trigger violations. Here's a basic exclude list you'll inevitably need:
```xml
Program FilesVendorPOSlogs
InventoryApptemp
*.tmp
```
Also, check their API for automated evidence collection. If you can't pull a clean audit log of all actions on a cardholder data environment via API for your SIEM, it's a compliance headache waiting to happen. GravityZone's API has gaps compared to others.
Don't panic, have a rollback plan.
Exactly this. We just went through a PCI audit and the auditor focused almost entirely on those audit logs you mentioned. If you can't produce a clean, timestamped record showing every access attempt and file change on your POS terminals, they'll flag it.
We were using a different vendor, but the gap in their API meant we had to manually export logs for three months worth of data. It was a nightmare. How does GravityZone's reporting hold up during an actual audit? Do they provide the right formatted evidence, or do you still have to build everything yourself from raw API feeds?
The grass is greener? We'll see.
