Commercial National Security Algorithm (CNSA) Suite Encryption

GoSilent uses CNSA Suite Encryption.

NIAP Approved Solution for Remote Access


NIAP certification is a commercial cybersecurity product certification that is mandated by federal procurement requirements (CNSSP 11) for use in U.S. National Security Systems (NSS). Its primary purpose is to certify commercial technology or products which will be used to handle sensitive data.


Archon’s GoSilent is NIAP-approved for use under the VPN Gateway Protection Profile.

CSNA Encryption for Your Outer VPN Tunnel

Archon’s GoSilent Cube is an enterprise-grade firewall and VPN product that has been NSA-certified for use as the outer tunnel component in CSfC mobile access solutions.CSfC_diagram

Using two nested, independent encryption tunnels helps to protect the confidentiality and integrity of data as it moves through an untrusted network. Each of the two tunnels helps protect data flow by using one of two independent encryption protocols:


Internet Protocol Security (IPsec) generated by a Virtual Private Network (VPN) Gateway

Media Access Control Security (MACsec) generated by a MACsec Device.


The outer tunnel of a dual tunnel VPN refers to the components that terminate the outer layer of encryption.


GoSilent utilizes AES 256-bit encryption for the outer tunnel to protect your private data and keeps it fully encrypted end-to-end. Data is never stored on an intermediary server. In keeping with Top Secret level encryption standards, there are no extra keys. Archon Security does not record, copy or have access to the encryption codes. This means that your data remains secure, even if compromised.

What does CNSA Encryption Mean?



14 rounds of encryption
Each 256-bit encryption key scrambles the data and divides into 128-bit blocks.
Top Secret level encryption standards
Data is never stored on an intermediary server. No record, copy or access to encryption codes.
AES 256-bit encryption
AES 256-bit end-to-end encryption is the most secure solution in the marketplace.
