HiveMQ MQTT Broker
The Trusted Enterprise-Grade MQTT Broker
At the heart of the HiveMQ Data Streaming layer, the MQTT Broker ensures reliable, event-driven messaging between connected devices and enterprise systems. Fully compliant with the MQTT standard and proven in mission-critical use cases, it delivers the resilience and scale for millions of connections and billions of messages.
From Spaghetti Connections to a Reliable Backbone
Point-to-point integrations create fragile webs that collapse under industrial scale, adding complexity, risk, and wasted effort. HiveMQ Broker replaces that mess with a clean, reliable backbone where every device connects once and data flows instantly without loss or fragile code. This scalable, event-driven architecture grows to millions of connections and becomes the foundation for real-time analytics, AI, and autonomous operations.
Why Enterprise-Grade Matters
Not all MQTT brokers are created equal. Some are designed for experiments, hobby projects, or small-scale device messaging. HiveMQ is built for something very different: mission-critical, enterprise-grade operations.
An enterprise-grade MQTT broker is infrastructure you can trust to move data securely and reliably at scale. It guarantees message delivery, provides high availability through clustering, enforces fine-grained security, and scales elastically to millions of devices and billions of messages. This is what makes HiveMQ the foundation for large-scale IoT deployments and real-time, data-driven industrial operations.
HiveMQ Broker Key Benefits
HiveMQ Broker is the enterprise-grade MQTT backbone for industrial data streaming. It enables reliable, secure, and scalable movement of data between connected devices and enterprise systems. Proven every day in mission-critical production deployments, it forms the foundation of event-driven architectures that power real-time insights, automation, and industrial AI at scale.
Always-On Reliability
Keep critical systems running with 99.999% uptime. HiveMQ’s high availability clustering, persistent storage, and hot upgrades prevent downtime and ensure no data is lost even during infrastructure failures.
Secure, Compliant Data
Protect data in motion with enterprise-grade security, including TLS 1.2/1.3 encryption, mutual TLS, fine-grained access control, pluggable authentication (such as OAuth 2.0 and LDAP), and detailed audit logging.
Proven Scalability
Scale confidently without re-architecting. HiveMQ delivers consistent performance across millions of connections and dynamically scales as you grow, proven by benchmarks of 200M concurrent connections and 1M messages per second.
Seamless Integration
Streamline enterprise integration by connecting IoT data to cloud, analytics, and business systems. HiveMQ’s open APIs and native extensions to Kafka, databases, and other enterprise systems enable real-time insights without custom middleware.
