Subprocessor register template for B2B SaaS
A subprocessor register helps buyers understand which vendors touch customer data, why they are used, and where to find the vendor's own security information.
Minimum columns
- Vendor or subprocessor name.
- Business purpose, such as hosting, analytics, support, email, billing, or AI assistance.
- Data handled, written plainly.
- Region or hosting location if known.
- Security page, DPA, or trust-center link.
- Internal owner and review date.
Be clear about AI vendors
If AI tools touch customer data, do not hide them in a vague vendor list. State the tool, approved use, prohibited data, human-review expectation, and how clients can request limits.
Keep it current
A short register reviewed monthly is better than a beautiful spreadsheet nobody trusts. Buyers mainly need evidence that the team knows which vendors exist and can explain why they are there.
