Layer 2 encryption provides an effective solution to secure high speed point-to-point link data network while minimizing the negative impacts usually associated with encryption.
As secured wired and wireless point-to-point connections over WANs continue to proliferate, the new Layer 2 products better serves these markets with a superior security solution that can overcome the operational complexities associated with traditional IPSec applications. Layer 2 encryption introduces virtually no latency to the network. Because Layer 2 operates one layer below the network, the devices are protocol independent and not affected by changing network configurations. Consequently, Layer 2 security solutions are simpler and less expensive to manage as changes within the WAN do not affect the encryptor's operation.
Governments and large enterprises that have multiple sites and are connected via Frame Relay, Gigabit Ethernet, or SONET can utilize Layer 2 solutions to encrypt the entire WAN connection.
Layer 3 IP Network Encryption
Layer 3 applications are appropriate for meshed network architectures, which allow the customer the ability to leverage the public infrastructure to connect to multiple sites. Thales provides a full range of IP-based encryption solutions, which can be deployed in large scale network architectures.
