MISP

MISP (Malware Information Sharing Platform & Threat Sharing) is an open-source platform designed to collect, store, and share structured threat intelligence. It allows security teams to share indicators of compromise (IOCs), malware attributes, and threat events with trusted partners. MISP provides a powerful correlation engine, fine-grained sharing policies, and multiple export formats including STIX and OpenIOC. It supports automated ingestion via APIs and integrates with other threat intelligence platforms. Organizations use MISP to enhance situational awareness, improve detection capabilities, and collaborate efficiently on cybersecurity incidents.
