Built on OpenNHP — The Internet Standard for Invisibility.
OpenNHP is a cryptographic protocol that makes infrastructure invisible to attackers while remaining accessible to authenticated users. Developed with the Cloud Security Alliance, it's the foundation of next-generation preemptive security.
How OpenNHP Works
Single Packet Authorization (SPA) flips the security model. Instead of exposing services and filtering bad actors, hide everything and only reveal to verified users.
Default Deny
All ports closed. No response to any probe. Your infrastructure is invisible to scanners.
Cryptographic Knock
Authenticated users send a single encrypted packet proving identity before any connection.
Micro-Authorized Access
Port opens only for that user, only to that resource, only for that session.
The result: Attackers can't exploit what they can't see. No reconnaissance, no vulnerability scanning, no lateral movement.
What Makes OpenNHP Different
Invisible by Default
Unlike firewalls that respond to probes, OpenNHP makes infrastructure undetectable. No ports, no banners, no attack surface.
Zero Latency Overhead
Single Packet Authorization adds <1ms latency. No VPN tunnels, no performance degradation.
Identity-First Architecture
Authentication happens before network access, not after. Integrates with your existing IdP (Okta, Azure AD, etc.).
Why LayerV?
OpenNHP is the protocol. LayerV.ai is the enterprise platform.
Enterprise-Ready
Production-hardened implementation with SLAs, support, and compliance documentation.
Managed Infrastructure
Global edge network, automated deployments, and monitoring — so you focus on your business.
Security Expertise
Direct access to the protocol co-authors. We don't just implement the spec — we wrote it.
