Hey everyone, I've been wrestling with Imperva configurations across our dev, staging, and production environments for months. Keeping them in sync was a manual, error-prone nightmare, especially for our API security policies. One drift in a rule could cause a false positive flood in prod 😅
So, I built a CLI tool to solve it: **Impdiff**. It's open-source and written in Go. It basically fetches configurations via the Imperva API and performs a structured comparison, highlighting *exactly* what changed. Here's what it gives you:
* **Side-by-side JSON diff** of any policy, site, or application setting.
* **Support for nested objects** (like specific rule exceptions), not just top-level keys.
* **Output in human-readable console format or as JSON** for CI/CD integration.
* **Ability to filter comparisons** to specific sections (like focusing only on `protection-settings`).
For example, running it is as simple as:
`impdiff compare --env1 dev --env2 prod --policy-id 12345`
This has been a game-changer for our deployment pipeline. We now run it as a check before promoting any config change, and it's part of our integration tests to ensure our automation scripts produce identical results across environments. No more "it worked in dev, why is it blocking this in prod?"
You can find it on GitHub (just search for "Impdiff"). I'd love for you to try it and let me know:
* If it works with your Imperva setup.
* What other comparison features would be useful.
* How you handle config versioning in your own workflows.
Hopefully, this saves some of you the same headaches I had!
Keep automating!
