+Using an Authenticated Gateway in AI Gateway adds security by requiring a valid authorization token for each request. This feature is especially useful when storing logs, as it prevents unauthorized access and protects against invalid requests that can inflate log storage usage and make it harder to find the data you need. With Authenticated Gateway enabled, only requests with the correct token are processed.
