MQTT Service
The future of IoT demands more than connectivity — it requires secure, scalable, and flexible messaging. The Cumulocity MQTT Service delivers enterprise-grade performance with developer-friendly simplicity, enabling you to connect millions of devices and innovate with full visibility and control.
Secure. Scalable. Developer-friendly. IoT messaging, redefined
Built for modern IoT
Our MQTT Service is architected specifically for Industrial IoT; validated for 100 million connected devices and one million messages per second.
With support for arbitrary payloads and flexible topic structures, you can speak your device’s native language without reformatting or rewriting. Map your data to Cumulocity APIs your way, with full control and zero friction.
A platform, not just a broker
The Cumulocity MQTT Service isn’t a repurposed enterprise broker. It’s purpose-built for IoT; tightly integrated with Cumulocity’s device management, analytics, and automation capabilities.
That means faster onboarding, simplified operations, and future-ready scalability, supported by the same ecosystem trusted by 200+ enterprises and powering 20 million connected devices worldwide.
Ultra-scalable and secure
Handle millions of concurrent connections with low latency and horizontal scalability. Every connection is protected through bi-directional TLS, X.509 authentication, and built-in device and tenant isolation — ensuring end-to-end security across your entire fleet.
Cumulocity’s multi-tenant architecture guarantees separation by design, keeping each device and customer fully protected.
MQTT — your way
Use MQTT v5, SmartREST, or custom microservices to integrate on your terms.
Support existing Cumulocity devices using SmartREST alongside “generic” devices that connect over any MQTT or REST-based protocol. Publish and subscribe with any topic or payload format — no rigid schemas, no unnecessary translation. Just clean, flexible integration that fits your existing systems.
Deployment on your terms
Deploy in the cloud, on-premises, or at the edge, with consistent functionality, security, and performance across all environments.\
From air-gapped industrial sites to global SaaS deployments, your architecture, your rules.
