Someone mentioned UUNET's DES box. I asked them for info, and received
permission to publish it, so here it is. I apologize to any of you who think
this is commercialism; *I* think it's relevant to the list.

UUNET Lan Guardian (TM)
Secure Connectivity over Public Internets
Introducing the Lan Guardian
The UUNET Lan Guardian is the first in a family of network
security products from UUNET Technologies, Inc., of
Falls Church, VA. The Lan Guardian is a hardware security
solution designed for companies that wish to benefit from
the cost savings of using Commercial Internet Service
providers (such as UUNET's AlterNet IP service) but are
concerned about the security of their confidential data
once it leaves their facility.
What does it do?
The Lan Guardian addresses those concerns by "splicing"
into the connection between the company's Ethernet and
external router and encrypting all data sent between company
networks, while also (optionally) allowing connections to
non-company facilities to continue without encryption.
Operation of the Lan Guardian is totally transparent to
network users and is simple for network administrators to
manage. Full configuration support is provided.
The Lan Guardian selectively encrypts or decrypts each packet
based on the information in the packet header. Only the data
portion of the packet is encrypted, thereby allowing the packet
to be transmitted with normal routers. The Lan Guardian may
also be configured to block selected or all external traffic
as well as to use a different key for each network.
By using fast processors and hardware encryption chips, the
Lan Guardian can encrypt/decrypt while only adding less than
a millisecond of delay. It is imperceptible to the network's
users, while providing peace of mind to the network's managers.
Using the Lan Guardian eliminates the concern that all users
are running the appropriate application packages and using
the appropriate level of security when sending sensitive
company data outside the company facilities. The Lan Guardian
ensures that company proprietary data sent to remote offices
is never in the clear. This allows companies to exchange
sensitive financial data or business plans with their remote
offices via a Commercial Internet Service provider without fear
that the data will be compromised.
How does it work?
Functionally, the Lan Guardian is a 50 MHz Motorola 68040,
with Dual Intel 82596CA Ethernet Processors, a CEI 99C003 Super Crypt
High Speed Encryption Chip and 4 - 32 Megabytes of Main Memory.
Keys are exchanged out of band via either a serial port or a
floppy disk. Support for Public Key based key distribution is
Optional "firewall" and other functionality will be available
later this year. Additional models including T-1 speed serial
interfaces will be available soon.
How can I get a Lan Guardian?
Existing AlterNet customers may purchase the Lan Guardian now
for US$6,000 or optionally lease for $500/month. The Lan Guardian
carries a one year hardware and software warranty.
