Earlier prevention.
A place to understand the professional strand of our community work: careful review, proportionate marketplace engagement and learning that can help prevent avoidable harm.
The shared approach
From an observation
to an informed response.
Community contributions inform a process. They do not replace competent assessment or regulatory decisions.

Ask for product-specific evidence and authenticate technical documents with their issuer when appropriate.
Understand careful reviewPREVENTION03
Request proportionate action.
Seek trained human review, traceability and temporary suppression where a credible risk warrants investigation.
