Map a client's vendor chain, then check the rows that matter.
SaaS Trust Graph
Map the vendors in a stack.
A Vendor Chain Audit is a hand-built map of the vendors in one client's stack and the subprocessors those vendors name on their published lists.
- Multi-tier map, checked against published lists
- AI subprocessors flagged
- Evidence you can put in an audit file
Vendor Dependency Watch
Start from declared lists.
The free index shows declared subprocessor lists and candidate rows. A paid audit checks the rows that matter for a client.
- Declared lists and candidate rows on the free index
- Hand-checked rows in a Vendor Chain Audit
- A dated sample audit is public
Change notices
Ask to be told when a list changes.
The public tracker can store an email address and the vendors you want watched. Nothing is sent from that form. Paid monitoring is separate, and the pilot prepares change notices by hand.
- Watch requests stored from the public tracker
- Monitoring is $99/mo, sold separately
- Pilot notices are prepared by hand
