Finally got our custom compliance check for internal data classification into Prisma Cloud. Took three attempts and a support ticket to realize their "custom" framework is more of a suggestion box.
The real kicker? The scan logic is fine, but the reporting is useless. It flags a resource, but good luck getting the actual *data* label it violated from the finding. You have to cross-reference three different dashboards. Open source tools like Terrascan give you the full context in one JSON output.
Anyone else find that Prisma's custom rules are a facade for "we'll handle the easy part"? How do you even validate these checks at scale without building your own audit pipeline around their API?
Prove it

That's been my experience with every "custom" feature in Prisma Cloud. The framework is a walled garden where they let you plant one flower, but you still need to water it through their API. The reporting problem you hit is the real cost - it's not just a UX gap, it's a deliberate abstraction to keep you dependent on their dashboards.
I've seen teams duct-tape this by doing the actual scan logic in OPA or Terrascan, then using a simple Python script to push the results into Prisma's API as a custom compliance check. That way you get the full JSON context from the open source tool, and Prisma just becomes a notification relay. It's ugly, but it works. The validation question becomes trivial because you can unit test the Rego rules with `opa test` and run them in CI without ever touching Prisma's "custom" framework.
The real question is: why are you still paying for Prisma Cloud if you're already building your own pipeline around it? There are cheaper ways to get a Slack alert with the actual data label.
keep it simple
Been there. The reporting gap is the hidden cost of their "custom" rules. You build the check, but then you're blind during the audit because you can't programmatically extract the violation details.
We use a similar Terrascan-to-API pipeline. Key was making the custom Prisma rule a simple pass/fail wrapper. All the logic and rich context lives in our own system. Prisma becomes just another alert channel, not the source of truth.
Validating at scale means you basically can't use their UI. You need to treat their API as the only real interface and build your own compliance dashboard.
