VPN encryptor
CompuGuard VPN 4000 was an encryption/decryption device for the
end-to-end protection of IP-based Virtual Private Networks (VPN),
developed by Compumatica
in Uden (Netherlands) and Aachen (Germany)
in 2003. It was suitable for fast (100 Mbps) TCP/IP computer networks.

CompuGuard VPN 4000 is housed inside a deep heavy 1U 19" rackmount
case. Apart from the power switch, the unit has no physical controls.
At the rear are two RJ45 UTP sockets for the connection of the unprotected
outside network (cipher) and the Local Area Network (LAN)
that has to be protected (plain). At the front are four indicator lights
that show correction operation of the PSU, the status of the unit, any
network traffic and a failure of the fan. Also at the front panel
is an RS-232 configuration port for the connection of a standard
serial VT102 terminal.

In order to minimise downtime in case of a system failure, it was possible
to connect two VPN 4000 units together as a redundant system.
The two units were linked via a 9-pin RS-232 cross-over cable connected
to the redundancy ports at the rear.
In case of a system failure, the backup system would
automatically take over the identity and security tasks of the 'master'
system.
The CryptoGuard family of devices was initially developed by KryptoKom
(later Utimaco) in Aachen (Germany) in 1993. In 2002, Utimaco Safeware
GmbH was taken over by Compumatica and was renamed to Cryptomatica Aachen
GmbH. In 2004, the CryptoGuard products were approved by the
BSI for military use in Germany (VS-NfD).
In The Netherlands, the VPN 4000 was approved by the AIVD/NBV for the protection
of information up to the level of RESTRICTED.
