    AI SPERA

    Criminal IP is a comprehensive threat intelligence search engine that detects vulnerabilities of personal and corporate cyber assets in real time and facilitates preemptive responses accordingly.

With Criminal IP’s 4 main features (Asset Search, Domain Search, Exploit Search, and Image Search), you can find IP risk scores and related vulnerabilities of searched IP addresses and domains, details on the exploit codes for each service, and assets that are left wide open to cyber threats in the form of images respectively.
