Enigmätron, High-Security Data Encryption Equipment


Valiant’s Enigmätron is a high-security data encryption device that provides data encryption, including Ethernet frame encryption for Layer 2 networks, IP packet encryption for Layer 3 networks, and Layer 4 data payload encryption for IP and MPLS networks. The Enigmätron offers full-duplex encryption at speeds up to 12 MBits/s @ AES-256 algorithm, using TLS and SHA-1 for secure communication authentication.

Valiant’s Enigmätron is an easy-to-use encryption device with extremely advanced firewall features that may be installed to secure RTUs, SCADA Terminals, Smart Grid distribution systems. The Enigmätron may also be installed in centrally managed encryption networks consisting of multiple branch offices edge installations to secure installation such as Point-Of-Sale Terminals, ATM Networks.

Power Point Presentation (PPS)

The Enigmätron also includes a 4 port integrated Ethernet switch which allows a connection of up to 4 Terminals, such as RTUs etc. thereby reducing the cost by avoiding the need to deploy additional Ethernet switches at the network edge.


The Enigmätron uses Broadcast Encryption technology to provide scalable encryption Broadcast encryption enables encrypted message transmission to various local/remote clients having different keys.

Access to Enigmätron is password protected with advanced firewall capabilities that meet and exceed NERC as well as all mandatory requirements of Password Protection and Control as provided in the GR-815-CORE-2 specifications. Enigmätron can optionally be managed centrally from a RADIUS Server to provide enhanced levels of access security and central password management and control.
