We ran both for six months. Here's the raw data from our SOC's actual workflow.
**The Setup:**
- 5000+ mixed Linux/Windows endpoints.
- EDR only, no firewall/cloud modules.
- Same alert feed, same Tier 1 analysts.
- Measured: mean time to acknowledge (MTTA), false positive rate on common alert types, resource overhead.
**The Punchline:**
Cortex is the over-engineered Swiss Army knife. Falcon is the scalpel.
Cortex's "machine learning" for process lineage is computationally expensive and mostly noise. Our analysts spent more time dismissing bogus "suspicious script" alerts than investigating real threats. The console is a maze.
```
// Example: Cortex alert for "suspicious PowerShell"
// Actual cause: a scheduled task for log rotation.
Alert Context: ParentProcess: 'svchost.exe' -> ChildProcess: 'powershell.exe' -> ScriptBlock: 'Get-ChildItem...'
```
Falcon's detection was simpler, often just a hash or signature match, but it was right. Their console is fast. The overhead on the endpoints was 40% less CPU on average.
**The Cost:**
Palo Alto's sales team talks "integration" and "platform." You pay for that. The per-endpoint cost was nearly double for features we didn't use. CrowdStrike's licensing was straightforward: you want EDR, you pay for EDR.
For a typical SOC that just needs to find and stop breaches, Falcon got the job done with less fuss and less cash. Cortex feels like a solution looking for a problem that most shops don't have.
