KoolSpan Secure LAN Bridging Solution

KoolSpan securely and simply connects LANs with a cost-effective and scalable security model that dramatically reduces the complexity of network design and application access.

Designed to protect and extend an enterprise network geographically and across dissimilar network topologies, KoolSpan operates without modification to existing networking equipment or mission-critical applications that run on the network. Applications such as e-mail, VoIP, groupware, disaster management, and CRM systems become instantly available, without modification or infrastructure replication in the field.

Compatible with all networks and applications, KoolSpan’s operation is transparent to its users, offering the following benefits for a wide range of LAN-to-LAN bridging configurations and applications:

• LAN Simplicity – Establish easy-to-use-and-manage LANs across any geography, and even across disparate network domains
• Public Networks – Migrate from private circuits to public networks with trusted links
• TCO and ROI – Provide access to business applications without replication of expensive servers and data center resources
• Business Continuity – Deliver all network services accross instantly established Ethernet links
• Strong Security – Deliver award-winning 256-bit AES encryption with per-packet keying and little or no network overhead
• Automated Security – Secure unicast, multicast and broadcast traffic automatically

Strongest Security Available

KoolSpan uses Smart Cards, a proven technology for robust and secure authentication. Embedded in each KoolSpan network appliance, Smart Cards are used as trusted components that independently authenticate each other and securely compute 256-bit AES session keys, which are then used to protect all network communications.

KoolSpan provides Layer 2, on-chip Ethernet Encryption, and the encryption key is changed with every packet. Layer 2 implementation provides true bridging, and results in transparent operation for all higher-layer protocols and IP applications. The AES algorithm encrypts without expanding the size of the source data, resulting in no impact on performance or speed.
