High performance VPN concentrator The ZyWALL 1050 allows organizations to establish Virtual Private Network (VPN) connections among multiple locations (such as remote branch offices, business partner sites and remote teleworkers). Data is encrypted in a VPN to secure communication channels and prevent confidential information from being eavesdropped over the Internet. Communication through VPN tunnels is protected from session hijack attacks and information theft. These security features are integrated in the ZyWALL 1050 to provide seamless data protection before transmission to a trusted network over the VPN. The Hub and Spoke VPN feature dramatically reduces management overhead and complexity in a complex, multi-site corporate network infrastructure.User-Aware policy engine enables access granularity In addition to basic access control capabilities, the intelligent user-aware policy engine on the ZyWALL 1050 is designed to make packet-forwarding decisions based on multiple criteria (such as user ID, user group, time of access and network quota, etc.). In addition, you can apply access policies to other security features such as VPN, content filtering and application patrol. In conjunction with network partitioning, corporate security policies can be effectively enforced to prevent unauthorized access to network or network resources.Proactive network protection mitigates security breaches With the embedded signature-based IDP (Intrusion Detection and Prevention) engine, the ZyWALL 1050 performs L7 packet inspection for protocol anomaly or matched patterns. Thus, the ZyWALL 1050 provides comprehensive Intrusion Detection and Prevention capability to proactively detect and block potential worms, viruses, Trojans, VoIP threats, etc.. ZSRT (ZyXEL Security Response Team), ZyXEL's dedicated security experts, releases up-to-date IDP signatures/patterns in response to ever-evolving vulnerabilities/exploits. New updates are automatically downloaded and installed through ZSDN to your ZyWALL 1050.Customizable security zones deliver flexible policy management The ZyWALL 1050 supports L3 virtualization techniques (VLAN and virtual/alias interface). You can set VLAN or virtual interface to different physical ports as needed. In addition, you can group the VLANs and virtual interfaces in a zone to which consistent security policies are applied. With the virtualization and zone concepts, the ZyWALL 1050 offers flexible deployment and easy security policy management in large/complex networking environments.Bandwidth management ensures quality of service ZyWALL 1050 provides the bandwidth management feature for traffic prioritization to guarantee or restrict the bandwidth usage per connection. You can allocate bandwidth to traffic types or computer hosts in the corporate network. i
