HiveMQ Security

Security is a key concern for any IoT application. HiveMQ implements the security features required for safe and secure enterprise IT and OT deployments.

Key Features

TLS / SSL Encryption

  • Secure communication between HiveMQ and MQTT clients.
  • Secure communication between HiveMQ cluster nodes.
  • Native TLS/SSL support for increased performance.
  • OCSP Stapling caches the result of the OCSP responder with the Broker so individual MQTT clients no longer need to check OCSP.

Pluggable Authorization and Permissions

  • Assign fine grained permissions to clients to restrict the access and the actions to different MQTT topics.
  • Assign fine grained permissions to HiveMQ Control Center users to restrict the access to different pages and data available in the HiveMQ Control Center.

Overload Protection

  • Throttles overactive publishing clients so HiveMQ broker is not overloaded.
  • Dramatically improves the resiliency of a HiveMQ cluster.

Pluggable Authentication

  • Authentication of MQTT clients can be done through external sources, ex. device name and password in a database.
