Threat Intelligence

Threat Feeds

Free, machine-readable indicators enriched from our threat reporting. Only values that meet the current exact, fresh malicious-evidence policy enter these feeds; clean, unknown, pending, and unsupported values stay out.

7 live indicators·4 reports·checking live guard

Values are live and functional. Provider matches are evidence rather than universal ground truth, and fast-moving network indicators expire automatically. Stage the feeds in monitoring and review impact before enforcement.

Blocklists (plain text)

One indicator per line. Import into a review or monitoring workflow before enforcing blocks.

Domains0

Domains admitted by fresh exact-match malicious evidence for DNS and web-proxy monitoring.
