Financial Services Information Sharing and Analysis Center (FS-ISAC) is the most relevant choice for a financial institution seeking to share and receive threat intelligence that is specific to their industry. FS-ISAC is a member-driven organization that focuses on the gathering and dissemination of cyber and physical threat intelligence analysis specifically for financial institutions. While sector-specific ISACs focus on the particular threats to their sectors, InfraGard and FIRST are more general and do not necessarily concentrate on the financial sector. Although Interpol provides international police cooperation and might share financial crime-related information, it doesn't offer the same closeness and detailed sector-specific data as an ISAC dedicated to financial services.
