Questions buyers ask

Is Vercel ISO 27001 Annex A compliant?

CertReports does not decide that. It shows the public evidence that may support each ISO 27001 Annex A requirement that reaches vendors: evidence was found or is available on request for information security in supplier relationships (Annex A 5.19), security within supplier agreements (Annex A 5.20), the ict supply chain (Annex A 5.21).

What should I ask Vercel for?

Request data processing agreement, published subprocessor list, and confirm each is current.

This maps third-party obligations to the vendor evidence that may support them. It is not legal advice and never a statement that a vendor or its customers comply; confirm scope and sufficiency with your counsel or auditor. “No public evidence” means nothing public was found at the last check. Citations link to the official text.

Requirements reviewed 21 Sep 2026. The vendor lists the evidence on its trust centre behind a request or NDA; ask for it.
