 ## Solution: OpenNHP Fixes the Network Visibility Control
 
 **OpenNHP** is the open-source implementation of the NHP protocol. It is cryptography-driven and designed with security-first principles, implementing a true zero-trust architecture at the *OSI Session Layer*.

 ## Comparison between SPA and NHP
 The Single Packet Authorization (SPA) protocol is included in the [Software Defined Perimeter (SDP) specification](https://cloudsecurityalliance.org/artifacts/software-defined-perimeter-zero-trust-specification-v2) released by the [Cloud Security Alliance (CSA)](https://cloudsecurityalliance.org/). NHP improves security, reliability, scalability, and extensibility through a modern cryptographic framework and architecture, as demonstrated in the [AHAC research paper](https://www.mdpi.com/2076-3417/14/13/5593).
