BOTHELL, Wash.--(BUSINESS WIRE)--March 19, 2003

Allied Telesyn, Inc. (www.alliedtelesyn.com), a world leader in network technologies for the access edge, today announced the expansion of its mid-range access router line.

The AT-AR410S includes essential security functionality that makes it ideal for telecommuting and branch office connectivity via the Internet.

The AT-AR410S includes a hardware accelerator for hardware-based VPN encryption, Stateful Inspection firewall and SMTP and HTTP Proxy application gateways.

Allied Telesyn's hardware-based VPN encryption is up to ten times faster than other well-known software algorithms. Because the encryption is performed on dedicated 32-bit encryption and compression processors, the router can maintain maximum DES or 3DES VPN speeds even when the CPU is under heavy demand from Stateful Inspection and IPSEC rule processing.

Allied Telesyn's ICSA-certified Stateful Inspection firewall provides the highest level of security possible by offering full application-layer awareness without breaking the client/server model. It protects against a wide range of Denial of Service (DoS) attacks including Ping of Death, SYN/FIN flooding, Smurf attacks, port scans, fragment attacks and IP spoofing.

SMTP Proxy, the first of two application gateways included on the AT-AR410S, inspects SMTP packets as they pass through the firewall. By accepting or rejecting packets based on source and destination address rules, abuse of e-mail servers is limited. The second, HTTP Proxy, inspects and filters outbound HTTP sessions as they pass through the firewall. The Proxy can inspect URLs and restrict cookie activity.

Unique for a product in this price range, the AT-AR410S supports port-based and 802.1q tagged VLAN operation across its 4 x 10/100Mbps switch ports. Hence, it offers a potent combination of wirespeed Layer 2 switching between VLANs as well as high performance Layer 3 routing between VLANs in one cost-effective device.

"With the inclusion of these security features, the AR410S router becomes the pinnacle product in the mid-range access router market," says James Mustarde, Vice President of Sales & Marketing. "No other manufacturer can offer the features of four separate devices consolidated into a single unit -- WAN connectivity, VLAN switching, Stateful Inspection firewall and hardware-based VPN encryption -- at such a compelling price point. This is proof that Allied Telesyn is changing the routing landscape."

At a list price of $1095, the AT-AR410S proves that VPN solutions can be simple and don't have to be cost-prohibitive. To learn more about Allied Telesyn's secure routing solutions, visit www.alliedtelesyn.com/security.
