New free tier brings “invisible” Zero Trust networking to the Home Lab, solving the most annoying NAT issues and safely closing all open ports for hobbyists, students, and prosumers
SAN JOSE, Calif., Dec. 16, 2025 -- Atsign, the leader in “security through invisibility,” today announced the immediate availability of NoPorts Personal, a free-forever tier of its enterprise-grade networking solution designed specifically for personal and non-commercial use. By making the same technology used to secure critical infrastructure and build guardrails for Enterprise AI deployments at no cost, Atsign aims to empower the “Home Lab” community to take their security to the next level.
Unlike traditional VPNs, mesh overlays (e.g., Tailscale), or cloud proxies, NoPorts does not bridge networks or create tunnels that can be laterally traversed. Instead, it connects specific devices and applications using cryptographic identity. Crucially, this architecture ensures absolute data sovereignty: all traffic is end-to-end encrypted using keys generated and stored only on the endpoint. Atsign and NoPorts never possess these keys and can never see anyone’s data in the clear.
For years, the Home Lab has faced a growing “Connectivity Crisis.” As ISPs aggressively deploy Carrier-Grade NAT (CGNAT) to combat IPv4 exhaustion, traditional remote access methods like port forwarding and dynamic DNS have become obsolete or dangerous. NoPorts Personal eliminates these barriers, providing a secure, invisible way to access home infrastructure without exposing a single IP address to the public internet.
“We believe that the techies running Kubernetes clusters at home today are the ones who will architect the secure enterprise clouds of tomorrow,” said Colin Constable, CTO and Co-founder of Atsign. “They deserve the same world-class security that protects critical utilities and sovereign AI deployments. With NoPorts Personal, we are eliminating the open port, instantly encrypting cleartext protocols like HTTP, MQTT, or MCP, and giving data sovereignty back to the individual.”
The End of the “Open Port” Era
NoPorts Personal allows people to connect to up to two devices completely free of charge. Unlike traditional VPNs that require complex configuration or cloud-based reverse proxies that decrypt traffic at the edge, NoPorts utilizes a unique outbound-initiated architecture (with full bidirectional data flow).
This means:
Optimized for the Modern Home Stack
NoPorts Personal is engineered to fit seamlessly into the diverse hardware and software ecosystems found in modern home labs:
