KlasOS Fastnet

Network Switch OS

KlasOS Fastnet Overview

Fastnet is a NIAP Common Criteria (CC) certified network operating system developed by Klas for its suite of Voyager products.

Fastnet supports L2/L3 switching for seamless integration of Klas modules as part of a wider network architecture.

Furthermore, Fastnet provides proven compliance in cryptographic implementations for secure configuration and management of Klas switch modules, in adherence with NIST Cryptographic Algorithm Validation Program (CAVP).

Fastnet on Klas Switch Modules

Fastnet ships on Klas switching modules of  VoyagerSW12GG and VoyagerTDC10G.

Fastnet Use Cases

Fastnet and Klas switch modules are used where the highest level of protection is required, protecting against sophisticated attempts of malicious actors who are targeting administration ports in order to gain access to networks. Government agencies, government contractors, and private-sector enterprises can trust that administrator identity, and administrative functions of device management and operations are safe no matter where the Klas switch module is deployed.


Furthermore, in adherence with NIST Cryptographic Algorithm Validation Program (CAVP), Fastnet has proven compliance in its cryptographic implementations. Validated capabilities include key management, random bit generation, encryption/decryption, digital signature, secure hashing, and key hashing features supporting high-level cryptographic protocols, including SSHv2.

Fastnet Packaging and Certification

Fastnet is delivered as a single image (.bin) file, signed with a digital signature for ease of secure updates.

The Common Criteria certification listing for Fastnet, on the VoyagerTDC10G and VoyagerSW12GG switches can be found at – https://www.niap-ccevs.org/Product/Compliant.cfm?PID=11188

Fastnet package differentiators:

  • Packaged as a single image file containing the entire operating system.
  • Digitally signed package, malformed or malicious images will not load in Klas modules.
  • Fastnet runs in RAM, and is not corrupted by the sudden loss of power.
  • Several versions of Fastnet images can be stored locally on the module for failover or fallback operations.
