SAN JOSE, Calif., April 08, 2025 (GLOBE NEWSWIRE) — Atsign, the developer of the innovative NoPorts technology, announces NoPorts now makes MQTT broker, gateways, and subscriber devices secure through invisibility by completely eliminating network attack surfaces. Using NoPorts to create an “invisible” MQTT infrastructure virtually eliminates external threats improving overall IoT security.
MQTT (Message Queuing Telemetry Transport), while efficient for IoT messaging, traditionally relies on open ports, creating inherent security risks. Atsign’s NoPorts technology addresses this by establishing secure, peer-to-peer connections without requiring any open inbound ports on any devices. Without open ports, there is nothing for bad actors to find when they scan for vulnerabilities. This “invisibility” provides enhanced protection against unauthorized access and data breaches.
“The reliance on open ports in traditional MQTT deployments presents a security challenge,” stated Colin Constable, CTO at Atsign. “NoPorts addresses this by removing the need for these ports, rendering the MQTT infrastructure effectively invisible to external scans. This ensures that brokers and subscribers are better protected from external threats, providing a more robust defense against unauthorized access and data breaches.”
Additional Advantages of Using NoPorts for Invisible MQTT
Along with making MQTT more secure, NoPorts offers IoT installations several additional advantages:
- Expedited Deployment: Streamlines IoT deployments by reducing the complexities of port forwarding and firewall configurations.
- Enhanced Security with Zero Trust Architecture: Aligns with zero trust security principles, ensuring all connections between broker, gateways, and subscriber devices are authenticated and authorized, regardless of network location.
- Simplified Management with Key Automation: Eliminates the need to manage certificates on all devices by enabling them to cut their own cryptographic keys.
How NoPorts Creates Invisible MQTT
Atsign’s NoPorts technology establishes direct, secure connections between MQTT clients and brokers using the Zero Trust architecture of the atPlatform. This eliminates the need for open ports, making the communication less visible to external scanners and attackers. Furthermore, all data transmitted through the NoPorts connection is automatically end-to-end encrypted, ensuring data confidentiality.
As shown in demonstrations, Atsign’s NoPorts technology allows MQTT communications to occur across disparate networks, even when devices are behind restrictive firewalls or NATs. This capability is useful for IoT deployments in challenging network environments.
“Atsign’s NoPorts provides a valuable solution for creating invisible MQTT deployments, enhancing overall security,” said Gareth Owen, CRO at Atsign. “By combining the efficiency of MQTT with the robust security of NoPorts, we offer a solution that addresses the critical security considerations facing IoT today.”
Atsign is dedicated to providing solutions that enhance security and simplify connectivity for people, entities, and things, including IoT and Ai. NoPorts compatibility with MQTT is a significant advancement in securing IoT communications.
