Methods, systems, and computer program products for providing anonymized account security services are disclosed. For example, a computer-implemented method may include an anonymous account security exchange for receiving anonymized user account information for a first user account identified as a security risk from a first organization associated with the first user account, receiving anonymized user account information for a second user account from a second organization associated with the second user account, determining that the anonymized account identifier associated with the first user account matches the anonymized account identifier associated with the second user account, and providing a notification to the second organization indicating that the second user account is associated with a different user account identified as a security risk by another organization.
