The VPN Advanced Integration Module (AIM) for the Cisco 1841 Integrated Services Router and Cisco 2800 and 3800 Series Integrated Services Routers optimizes the Cisco Integrated Services Router platforms for virtual private networks in both IP Security (IPSec) and Secure Sockets Layer (SSL) Web and VPN deployments.The Cisco VPN and SSL AIM provides up to 40 percent better performance for IPsec VPN over the built-in IPsec encryption, and up to twice the performance for SSL VPN encryption. The Cisco VPN and SSL AIM supports all three of these functions in hardware: SSL encryption in hardware, VPN IPsec encryption in hardware using either Data Encryption Standard (DES) or Advanced Encryption Standard (AES), and the IP Payload Compression Protocol (IPPCP) in hardware. Cisco Integrated Services Routers with the Cisco IPsec and SSL VPN AIM are ideal for use in small and medium-sized businesses (SMBs) and small and large enterprise branch offices to connect remote offices, mobile users, and partner extranets. Cisco Integrated Services Routers offer the flexibility to deploy both IPsec and SSL VPN in a single-device solution, thus reducing the total cost of ownership, unlike other vendors' products requiring multiple devices and management systems. In addition, the Cisco IPsec and SSL VPN AIM is designed for service providers, offering highly scalable managed security services with zero-touch deployment ease.
