X-ISAC logo

X-ISAC (pronounced cross-ISAC) is the supporting Information Sharing and Analysis Center for other ISACs, information sharing communities or CSIRT networks which provides core software, cross-sector threat intelligence, taxonomies and open standards.

Information sharing is now a key requirement in cyber security as well as in intelligence, counter-terrorism and financial fraud detection/prevention. X-ISAC is there to provide the tools and practices to enable and drive information sharing and exchange worldwide.

With the increase of sharing organisations and/or initiatives, bridging the exchange of information between communities is critical to ensure efficient collaboration, analysis and cross-sectorial exchanges. X-ISAC uses the MISP standard formats and technologies to enable users to benefit from different sharing models (centralised, partially-bridged, distributed) with continuous contributions from members (via proposals, collaborative intelligence support, sightings or expansions).
