Proofpoint ET Reputation

Proofpoint is a cybersecurity company that specializes in protecting organizations from digital threats. Their Emerging Threats (ET) Intelligence Rep List is a threat detection feed consisting of IP addresses and domain names associated with malicious activity, updated hourly from sensors deployed worldwide and a proprietary Malware Sandnet system. Each entry is categorized by behavior type and scored from 0 to 127 reflecting confidence in its malicious nature.

This connector imports malicious IP addresses and domain names from Proofpoint's ET Intelligence Rep List into OpenCTI as observables and indicators, with reputation scores mapped to OpenCTI confidence levels.
