Just spent two weeks deep in CloudGuard's DLP policies and OMG the alert noise was insane. Went from 200+ daily alerts to maybe 20 that actually matter. 😅
Here’s my quick tuning playbook that worked:
* **Start with exclusions, not inclusions.** CloudGuard's default DLP profiles are broad. First, I added trusted internal IP ranges and approved cloud storage domains to the exclusion lists. This cut out 50% of the noise right away.
* **Adjust confidence levels per rule.** That "High Sensitivity" credit card rule? It flagged every order confirmation PDF. I duplicated the rule, set one to "Medium" for internal traffic and kept "High" for external. Way more accurate.
* **Use tags and groups.** Don't just review alerts—tag them. I created tags like "False Positive - Internal Comms" and "Valid - Customer Data." After a week, I filtered by the false-positive tag and built an exclusion group from those sources. Rinse and repeat.
Biggest lesson: tune in stages and let it learn for a few days between changes. You won't get it right in one shot.
Anyone else have tips for handling PII detection without blocking legitimate HR workflows? Still tweaking that part.
