The problem

Malicious actors use IPs from known threat lists for fraud, account takeover, and attacks. Without blocklist checks, you allow known bad actors.

The solution

Check visitor IPs against our blocklist API. Block or flag IPs on inbound threat lists. Add an extra layer of security to your fraud prevention stack.

Everything this unlocks.
