Business operations have become more mobile than ever. New and advanced business applications have also created demand for faster VPN performance, which legacy firewall and UTM appliances cannot satisfy. To keep up with the dynamic business environment, business networks today need to provide branch offices, chain stores and mobile employees faster remote access to headquarter resources. Moreover, they must do so without exposing company resources and customer information to threat and data breach. ZyXEL's new ZyWALL Series VPN Firewalls are business-grade VPN gateways purpose-built to deliver the fastest performance for multi-site VPN deployments. These high performance VPN Firewalls feature multi-core CPUs and are fine-tuned to deliver ultra-fast performance with up to 3.6 Gbps firewall and 800 Mbps VPN throughputs. The new ZyWALL Series VPN Firewalls also feature the most advanced VPN functionality-SHA-2 encryption, VPN HA and L2TP-for more secure, more reliable and more mobile VPN connectivity. The new ZyWALL Series VPN Firewalls are designed with multi-core CPUs to deliver the fastest VPN and firewall performance on the market. High-speed networking performance is guaranteed with up to 3.6 Gbps firewall throughput and 800 Mbps VPN throughput-up to 9x the firewall performance and 4.4x the VPN performance of preceding models. Designed with completely new and advanced hardware platforms, the new ZyWALL Series VPN Firewalls deliver uncompromising performance for high-speed site-to-site and client-to-site VPN applications. Faster processors today have greatly boosted the capabilities of attackers to decrypt VPN tunnels. Legacy VPN encryption algorithms like Message Digest 5 (MD5) and Secure Hash Algorithm 1 (SHA-1) are no longer sufficient to guarantee secured external communications. Supporting the more advanced Secure Hash Algorithm 2 (SHA-2), the ZyWALL Series provides the safest VPN connections in its class and ensures maximum security for business communications.
