Palo Alto

The CrowdSec Palo Alto integration connects CrowdSec's hosted blocklist endpoint to your Palo Alto firewall.
Palo Alto calls this feature External Dynamic Lists (EDL), which allow you to import and automatically update blocklists from external sources.

Ensure your Palo Alto device supports External Dynamic Lists (EDL).
The vendor documentation is available in the References section below.

Create a Palo Alto Integration Endpoint

1- Create an integration

Step 1 — Create an integration in the CrowdSec Console

In your CrowdSec Console account, navigate to the Blocklist tab in the top menu bar, then select the Integrations sub-menu. Choose the integration type you need, then click Connect.

If you don't have a CrowdSec Console account, sign up here. On mobile, use the menu icon in the top-right corner, tap Blocklist, then Integrations.

2- Remediation Component

Step 2 — Fill in integration details

Name the integration (must be unique to your account) Optionally, add a description and tags to help you identify it later. Then click Create.

3- Save your credentials

Step 3 — Copy your credentials

The credentials shown next are displayed only once. Copy them before closing this screen. If you lose your credentials, you can regenerate them via Configure → Regenerate Credentials on the integration page.

With this HTTPS endpoint and Basic Auth credentials, you can verify the endpoint with any HTTP client, for example:

curl -u 'usr:pass' https://admin.api.crowdsec.net/v1/integrations/$integID/content

4- Subscribe to blocklists

Step 4 — Subscribe to Blocklists

The integration endpoint will serve the deduplicated blocklists it's subscribed to. After creation, a subscription pop-up appears automatically. You can also access it later via the Add Blocklist button.

Select one or more blocklists available for your plan, then click Confirm Subscription. The blocklist name(s) will appear in the integration tile once subscribed.
