What is Single Packet Authorization (SPA)?

Single Packet Authorization (SPA) lets a receiver validate a cryptographic request before permitting a connection. The implementation determines the packet format, replay protection, and resulting access window.

SPA is an authorization mechanism. It does not mean that every service on the host is hidden or that application authentication is unnecessary.

How LayerV Implements This

LayerV uses OpenNHP network-hiding authorization as part of access to published resources. A shared access link is a bearer credential; possession of it alone does not verify the identity of the person opening it.

Pilot LayerV

Tell us what to protect, and we’ll scope a pilot.

Enterprise starts with a scoped, paid pilot on one application, typically 60 to 90 days, credited in full toward year one if you convert within 60 days. Then an annual package sized to what you protect. Not per seat.
