The ISC Security Team operates as a free, cooperative cyber threat intelligence network. We collect, analyze, and disseminate data on malicious internet activity — enabling defenders, researchers, and incident responders to act faster than adversaries.
Our mission is rooted in community: thousands of volunteers and organizations contribute firewall logs, honeypot data, and incident reports daily. This collective intelligence forms one of the most comprehensive threat landscapes available to the security community.
Aggregating and correlating data from thousands of distributed sensors to identify emerging attack patterns, malicious IPs, and campaign infrastructure before they reach your network.
Rapid coordination support for large-scale incidents affecting multiple organizations. ISC handlers triage reports, identify scope, and publish guidance within hours of confirmed threats.
Deep technical analysis of newly disclosed vulnerabilities, active exploitation in the wild, and patch effectiveness — delivered before most enterprise patch cycles complete.
Static and behavioral analysis of malicious code samples submitted by the global community. Detailed reports cover capabilities, persistence mechanisms, and C2 infrastructure.
Longitudinal port scan and protocol data revealing shifts in exposed attack surface. ISC DShield data powers research into global exposure trends and scanning campaigns.
Free security education through the SANS Internet Stormcast podcast, daily diaries written by handlers, and open datasets used in academic research worldwide.
