Brief description of the ET-3300 and ET-6600
Encrypted Tunnels
Simple VPN Devices. No Software Required
The ET Series is a hardware security device. It provides a secure
encrypted Ethernet tunnel for connecting remote locations securely
through an insecure network, such as the Internet. Encryption
method is the AES, Advanced Encryption Standard. AES is an encryption
standard that is the recommended replacement for DES and 3DES. The
American government NIST fully endorses and recommends AES with no
restrictions: see FIPS-197 (Federal Information Processing Standard
number 197). Benefits:
• High Security
• Easy to install
• Low Cost
• Central Administration
• Tunnels all protocols
• Use low cost Internet connections for private line substitute
• Hardware solution for devices that do not support internal software
security ET Series - How it works,
key features
AES encryption (128 bit), key is periodically updated
Common pass phrase for ET to ET authentication, user pass phrase for
user authentication
Each ET6600 and ET-3300 supports up to 8 users, ET-6604 and ET-6620
supports 50 users
Links to the Internet from the ET can be Ethernet or serial
Ethernet links to the Internet can be configured for serial dial
backup
Very easy to set up using a web browser
Passes all protocols from one Ethernet network to another
Sustained throughput of approximately 800,000 bps

Common Applications
Utilities – Gas and oil production, pipelines, electric generation,
transmission and distribution
Retail – Stores, kiosks, credit card machines --- especially those
using wireless links
Law Enforcement – Small remote offices
Medical – AES encryption of the ET-6600 meets HIPAA requirement for
securing data over open networks such as the Internet. The medical
industry is mandated by HIPAA to meet HIPAA privacy and security
requirements over open networks.
Real Estate – Connecting to and updating the database of listed homes.
Field sales personnel working out of the home, hotel rooms wired for
high speed Internet access.
Financial industry – Additional security on internal corporate links,
branch offices, ATM machines, key personnel remote secure access.
Remote office with more than one device, with the ET-6600 shared with
switch or hub.
Added security within a large corporate network
Office to Home
2 nets at each end, bridged via the Internet
Remote network monitoring via the Internet
