# Manage custom certificates

Manage trusted certificates in Cortex XSOAR 8.13 On-prem.

For backup and restore, you can manage the list of certificates Cortex XSOAR trusts for outbound integrations and custom CA roots. This saves time by automatically syncing certificates across the entire cluster, eliminating the need for manual, per-node updates.

To manage the list of trusted certificates, run the **`manage_certificates`** command via SSH with the following subcommands:

| Subcommand   | Description                                                                                                             | Example                                                                                                                 |
| ------------ | ----------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- |
| **`apply`**  | Adds trusted CAs from a file path. If run without flags, the command reconciles the existing bundle across the cluster. | <p>Add a trusted CA:</p><p><strong><code>manage\_certificates apply -cert /tmp/customer-root-ca.crt</code></strong></p> |
| **`get`**    | Lists all currently trusted certificates or displays details for a specific certificate.                                | <p>List trusted certificates:</p><p><strong><code>manage\_certificates get</code></strong></p>                          |
| **`remove`** | Removes certificates from the trust store by their Common Name (CN).                                                    | <p>Remove a certificate:</p><p><strong><code>manage\_certificates remove -cert customer-root-ca</code></strong></p>     |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsoar-8-on-prem/8.13/install-cortex-xsoar/post-installation/manage-custom-certificates.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
