Whistleblowing platforms with a public API
Platforms documenting a public API, for organisations that need cases to reach an existing case-management, GRC, or SIEM system.
9 of 116 platforms in the directory meet this requirement.
Most organisations that already run a GRC or case-management system do not want a second inbox. An API is what determines whether a whistleblowing channel becomes part of the existing compliance workflow or a silo somebody has to remember to check.
This is also the field vendors most often leave undisclosed, so treat absence from this list as unknown rather than unavailable, and confirm before it becomes a requirement.
