An Information Sharing and Analysis Organization (ISAO) is a threat intelligence sharing community for organizations with common cybersecurity concerns and similar risk environments. ISAOs may choose to function as either for-profit or nonprofit entities and can be formed on the basis of industry sector, geography, or “any other affinity, including in response to particular emerging threats or vulnerabilities.” ISAO community Members, also referred to colloquially as Members, may be drawn from either the private or the public sector, or both.
