We've been running Prisma Cloud for about 18 months, primarily for CSPM in AWS. Our biggest hurdle has been tailoring the generic compliance rules (like the built-in HIPAA benchmark) to our actual, specific business context. The out-of-the-box checks often flag things that are irrelevant to our implementation or miss nuances in our data handling workflows.
For example, the default rule for encrypted S3 buckets is great, but we have specific buckets that are intentionally public for marketing assets. The generic HIPAA framework throws constant critical alerts, drowning our team in noise and causing alert fatigue. Our compliance officer needs reports that map directly to our internal control IDs, not just the standard sections.
Here’s what we’ve pieced together so far:
* **Custom Policies are essential.** We built a library of policies that layer our internal requirements on top of the base HIPAA rules. This means defining specific resource tags, allowed regions, and even approved AMI IDs as part of compliance.
* **We use a two-tiered tagging strategy.** One set of tags (`env=prod, data=phi`) triggers the strictest custom policies. Another set (`env=dev, data=test`) uses a modified, less restrictive rule set for our sandbox accounts.
* **Attribution is key for audits.** We funnel all Prisma Cloud alerts into our SIEM and tag them with the internal control ID (e.g., `HIPAA-164.312(e)(1)`). This creates an audit trail we can directly map to our compliance framework during reviews.
I’m curious how other teams are bridging this gap. Are you leaning heavily on custom policies, or have you found a way to effectively modify the built-in benchmarks? What’s your process for translating a framework like HIPAA or PCI-DSS into actionable, low-noise rules in Prisma?

Show me the pipeline.
Interesting about the two-tiered tagging strategy. That's exactly the kind of practical tip I need.
But I'm curious, how do you handle the initial assignment of those tags? Is it a manual process during provisioning, or did you automate it somehow? I can see a dev forgetting a tag and then the wrong policy set kicking in.
