MQ Extended Security Suite (MQESS) is a collection of security components designed to strengthen IBM MQ environments by providing additional controls that complement native MQ security features. The suite focuses on securing how applications and queue managers connect to MQ, how identities are validated, and how access decisions are enforced. It integrates with IBM MQ through supported extension mechanisms such as exits, ensuring compatibility with existing MQ infrastructures. MQESS is intended for organizations that require stronger, more flexible, or more auditable security controls than those provided by default MQ configuration options. It does not modify MQ internals or message data and is suitable for use in production environments.
