ShadowNet is a threat intelligence feed provided by RiskAnalytics, offered free to members of participating ISACs and information sharing organizations globally. The service uses a patented Threat Correlation Engine combined with a network of global sensors to identify IP addresses and domains actively involved in cybercriminal activity. This dynamically generated blocklist is pushed directly into a subscriber's network infrastructure in near real-time upon identification. ShadowNet is positioned as a security augmentation layer, designed to complement and integrate alongside existing security controls rather than replace them. It is available to members of a wide range of industry groups and ISACs, including OT-ISAC, K12-SIX, GRF, LS-ISAO, H-ISAC, EE-ISAC, Elections Infrastructure ISAC, KraftCERT, DNG-ISAC, EASE, NRF, MS-ISAC, ONG-ISAC, ProSIX, and others. It is also available for MSSPs, insurance partners, and businesses directly. Access is granted through registration via the relevant ISAC or program partner.
