Stop Connecting People to Networks. Connect Them to Services. NoPorts is a Zero Trust Service Access (ZTSA) tool designed to replace the broad "Network Access" model. Unlike VPNs or Mesh overlays that place devices on a virtual LAN, potentially exposing your entire subnet to lateral attacks, NoPorts creates a discrete, end-to-end encrypted tunnel to a single specific service on a device. Network Access vs. Service Access VPNs & Mesh Networks connect people to a network. If a device is compromised, the attacker can scan and move laterally across that network. NoPorts connects people, entities and devices to a service (e.g., localhost:22). They get no visibility into the rest of the network, the device's other ports, or the OS. If they are authorized for SSH, they get SSH and nothing else. Key Technical Features - True Invisibility - NoPorts uses an outbound-only architecture. There are no open listening ports on your firewall or device. Your infrastructure is invisible to Shodan, Nmap, and botnet scanners. - Granular Service Tunnels - Map a local port on your laptop directly to a remote service (SSH, RDP, VNC, HTTP, or MCP). The connection is peer-to-peer and service-specific. - Decentralized Identity - We don't store your keys. Authentication is handled via public-key cryptography on the device at the edge, ensuring NoPorts never sees your data or acts as a central point of failure. - Bypass Connectivity Hurdles - Works instantly behind CGNAT, Starlink, 4G/LTE, and firewalls without port forwarding or static IPs. Use Cases - Secure AI Agents & MCP Servers - Allow AI agents to access the various services they need to perform their duties by fully securing APIs and MCP servers, without having any of your endpoints be discoverable by unauthorized people or agents. - Starlink & Satellite Remote Access: overcome the limitations of Starlink's CGNAT (Carrier-Grade NAT) without needing to purchase a static IP or configure complex router settings. Perfect for maintaining reliable, secure connections to remote field sites, maritime vessels, and rural deployments where traditional VPNs fail. - Home Labs & Personal Servers - Securely access personal infrastructure (Home Assistant, NAS, Raspberry Pi) from anywhere without opening ports on your home router or configuring Dynamic DNS. Perfect for users behind CGNAT who need to reach specific services without exposing their entire home network. - IoT & Headless Devices - Manage remote edge devices (Raspberry Pi, industrial controllers) as if they were on your desk, even if they are buried deep behind a cellular NAT. - Sysadmin & Developer Access - Give contractors or developers access to a single server port without granting them VPN access to the corporate LAN.
