The EE-ISAC is an industry-driven, information sharing network of trust. Private utilities, solution providers and (semi) public institutions such as academia, governmental and non-profit organizations share valuable information on cyber security and cyber resilience. EE-ISAC aims to improve the resilience and security of the European energy infrastructure, by sharing trust-based information and enabling a joint effort for the analysis of threats, vulnerabilities, incidents, solutions and opportunities. EE-ISAC offers a community of communities to facilitate this proactive information sharing and analysis, allowing its members to take their own effective measures.
