Harness SaaS Delegates only need outbound access to the Harness domain name (most commonly, app.harness.io) and, optionally, to logging.googleapis.com.
The URL logging.googleapis.com is used to provide logs to Harness support.
Users of the Harness Manager browser client need access to app.harness.io and static.harness.io. This is not a Harness Delegate requirement. It's simply for users to use the browser-based Harness Manager.
If you are using a Harness vanity URL, like mycompany.harness.io, you can allowlist it also.
Allowlist Harness SaaS IPs
The following list is optional. You can allowlist these IPs if needed.
Harness will not change IPs without 30 days notice to all customers. If a security emergency requires a change, all customers will be notified.
