NoPorts Documentation

NoPorts improves remote access security and simplifies network and firewall configuration. Devices using NoPorts have no exposed ports, making them undetectable on a network scan.

Proactive Security

NoPorts shifts the security paradigm from “ports are open, I need to close them” to “ports are closed, I need to open them (securely).” Ports are closed and secure by default, allowing you to manage only the things you actively use.

Communication between devices is always peer-to-peer and end-to-end encrypted. Encryption keys are cut and stored securely on the device and controlled by the device owner.

Available via both command line and as a desktop application, NoPorts is already being used in the field to replace VPNs and firewalls, enable zero-trust remote access, improve cloud security, and apply Atsign’s preemptive security approach to a wide range of industries and use cases.
