The RedCreek Ravlin 3200 is a cost-effective network security solution that performs encryption and decryption for T1 communications access. Network administrators use it to establish private communications within secure intranets (between corporate divisions, workgroups, branch offices, and individuals) or within secure extranets (between customers, suppliers, and strategic partners.) Its low cost allows organizations to establish security over private or public IP networks quickly and easily. ??The Ravlin 3200 is typically installed behind an access router connected to a full-duplex T1/E1 wide-area network (WAN) circuit. It provides data privacy using industry-standard 56-bit DES and 168-bit Triple DES encryption. Authentication and access control with DSS (Digital Signature Standard), Diffie-Hellman key exchange, and IKE key management. These security standards are part of the Internet Engineering Task Force (IETF) IP Security Standard (IPSec).
