# OpenNHP

> OpenNHP is an open-source, cryptography-powered Zero Trust network hiding protocol for the AI era. It makes infrastructure invisible by default — no exposed IPs, no open ports, no DNS discoverability before authentication. Backed by the Cloud Security Alliance and being standardised at the IETF.

## Blog

- [AI Has Crossed the Expert-Attacker Threshold — Here's What It Means](https://opennhp.org/blog/ai-has-crossed-the-expert-attacker-threshold/): The UK AI Security Institute's first Frontier AI Trends Report documents AI completing expert-level cyber attack tasks that typically require 10+ years of human experience, with the duration of unassisted cyber attack tasks doubling roughly every eight months. OpenNHP's Zero Visibility architecture removes the attack surface before AI can act on it.
- [The Internet Is Becoming a Dark Forest — And AI Is the Hunter](https://opennhp.org/blog/the-internet-is-becoming-a-dark-forest/): How AI is transforming network threats, why visibility equals vulnerability, and how Zero Visibility architecture (OpenNHP) addresses the AI-era attack surface. References PentAGI (autonomous AI pentesting) and Claude Code Security (500+ vulnerabilities found in production codebases).

## Key Concepts

- **Zero Visibility**: Infrastructure is invisible until cryptographic identity is proven. No exposed IPs, no open ports, no DNS discoverability before authentication.
- **Zero Trust vs Zero Visibility**: Zero Trust verifies identity after contact. Zero Visibility eliminates the attack surface before contact is possible.
- **NHP (Network Hiding Protocol)**: The underlying protocol that enforces cryptographic identity-first connectivity.
- **Dark Forest Theory**: From Liu Cixin's sci-fi novel — any entity that reveals its location will be targeted. Applied to AI-era network security: visibility equals vulnerability.
