Dear Client,

As part of our ongoing security hardening, Sinch will enable active blocking on a baseline set of AWS-managed WAF rules for our Conversation API in the BR, US and EU regions.

These rules target known malicious inputs, botnets and known exploit patterns.

We have validated this change against recent production traffic to ensure impact is not observed as a result of this change, production impacting rules will be placed in monitoring mode until further notice.

Impact: No impact is expected.

Maintenance Start Time: 2026-12-01 11:00 UTC
Maintenance End Time: 2026-12-01 12:00 UTC
