These certificates are subsequently used to establish secure connections to these third party systems. All trusted certificates are monitored and when any are approaching their expiration, the Controller will issue a warning in the dashboard 30 days prior. > [!NOTE] > **NOTE** > > Adding or changing a certificate requires rebooting all appliances for it to take effect. This feature supports: - Identity providers - Name resolvers - API calls to third party systems - Log forwarding > [!NOTE] > **NOTE** > > Trusted Certificates cannot be used to [configure secure log transfer via RSYSLOG](/v1/docs/secure-log-transfer-via-rsyslog-v6-6) as it still requires manual configuration on both ends. Use the Trusted Certificates page to: - View all the Trusted Certificates you have configured in the Collective. - Upload new Trusted Certificates. - Perform actions using the action buttons. See the [Configure Trusted Certificates](/v1/docs/configure-trusted-certs-v6-6) page when you are ready to upload a certificate. ## Action Buttons Action buttons are accessed by clicking clicking the three dots icon (![Three circular shapes stacked vertically on a dark background, selected to access a menu.](https://cdn.us.document360.io/e7482ce5-acfa-4c3b-b76c-b6c32472644a/Images/Documentation/three_dots.png?sv=2026-02-06&spr=https&st=2026-10-26T22%3A31%3A24Z&se=2026-10-26T23%3A31%3A24Z&sr=c&sp=r&sig=%2Ba8ih15UWLvQG1GFV4qQdVE3sHQAjIO5kGAhMX2Vzdg%3D)) to the right of each line item in the page or from the button within the item.
