On plans that include it, add a Blocklist reputation policy (every 6, 12 or 24 hours). It checks whether the IP address or registered domain of a verified asset is listed on public blocklists, over DNS only: your site is not contacted.
- The Reputation tab and the asset's Monitoring tab show, per source, Listed, Not listed or Not checked. A list that refused or did not answer is never shown as clean.
- A listing raises an event and the "Listed on a blocklist" notification. When the list drops you, the event resolves and a recovery notification follows.
- Blocklists are run by third parties and can be wrong. Treat a listing as a signal to investigate, then ask the list operator for removal once the cause is fixed.
- Google Safe Browsing and other providers are shown as "not configured" unless the platform operator has set them up.
