Pick the vendors your company uses.
Browse the catalog of 263 — Stripe, OpenAI, AWS, Atlassian, Notion, and the rest of the usual stack.
We monitor every page for changes.
Each vendor publishes differently — HTML lists, PDFs, embedded tables, separate AWS-region lists. We normalize them so a change is a change.

FAQ
- Where does this data come from?
- Each vendor's official subprocessor page. We link the source and timestamp every check.
- Is this really free?
- Yes. It stays free for DPOs and vendor-risk teams. A separate paid product for vendors funds this side.
- How fast will I find out about a change?
- Within a week, while the catalog is hand-checked. Down to 24 hours once we automate — that's next.
- My vendor isn't in the catalog. Can you add it?
- Email hello@piilot.co. We prioritize by how many people ask.
- Are you affiliated with any of these vendors?
- No commercial relationship with anyone listed. We read their public pages, same as anyone.
- Who's behind this?
- Simon Turvey, solo for now. Built because no one should be tracking 80 vendors' subprocessor lists by hand.
