Protect your Critical Infrastructure with the atPlatform™
Eliminate open port vulnerabilities and cryptographically secure every connection. The atPlatform is advanced protection for your critical infrastructure.
The atPlatform redefines critical infrastructure security with innovations that remove weak points and safeguard your systems against evolving threats.
Eliminates Attack Vectors and Threats
Removes open port vulnerabilities and protects the application layer, preventing unauthorized access and ensuring comprehensive security.
Keys Cut and Encrypted at the Edge
Cryptographic keys are generated and encrypted at the edge, ensuring data security from origin to destination.
True Zero Trust Architecture
Every connection is authenticated and verified, delivering maximum security without assumptions or shortcuts.
Check out our atSDK to learn how to quickly build products and services with reduced attack surface, end-to-end encryption and zero trust security built in.
For over 50 years, the internet’s client-server model has relied on open ports, creating massive attack surfaces vulnerable to exploitation. Atsign eliminates this reliance by removing the need for listening ports on devices that hold sensitive data or services. Using our patented, open-source technology, we enable secure, seamless communication for critical systems and organizations—without requiring a major infrastructure overhaul—redefining internet security at its core.
How Atsign Protects Critical Infrastructure
The atPlatform enables secure, private communication for critical infrastructure by eliminating open ports, using cryptographically verified addresses, and cutting keys at the edge for advanced privacy and security at scale.
NoPorts is a tool built on the atPlatform that delivers secure remote access by eliminating open ports and using cryptographically verified, end-to-end encrypted connections. It enables secure communication between devices in different locations while being simple, scalable, and built for critical systems.

AI Sprawl: The Network Nightmare Caused by the AI Security Paradox
AI Sprawl is the resulting network complexity that occurs when enterprises must deploy many specialized AI agents to secure and govern the use of large language models (LLMs).
Why the Model Context Protocol (MCP) Demands a Structural Rethink of AI Security
AI agents using MCP bypass traditional network security, demanding an identity-first, Zero Trust architecture to eliminate the risks created by exposed ports and centralized tokens.
Why Our Cybersecurity Industry Is Fundamentally Broken
The $200B cybersecurity paradox is that breaches worsen because the industry's flawed economic model rewards liability transfer over true prevention, making a shift to preemptive, connectionless Zero Trust necessary.
