Whatoblock is a threat intelligence platform for security teams. Its HoneyBot sensors record unsolicited connections to exposed services, and you can investigate observed IPs and related activity. Modules include Heartbeat (proxy, Tor, datacenter and DDoS IPs), Scanners, Botnet C2 and Open Data (DNS, NTP, SSDP), plus a threat map and a status page.
Blocklists are offered in text, CSV, JSON and firewall formats through feed URLs. A free account lets you inspect the first five pages of live records and includes a sample blocklist feed. Paid plans add complete results, investigation tools and broader blocklist coverage. No prices are shown on the page. It is web only, and the call to action reads 'Start free, no sales call'.
Whatoblock is designed to make usable threat intelligence and IP blocklist feeds accessible to security teams and researchers without an enterprise sales process.
