CacheGuard-OS vs Riverbed SteelHead

CacheGuard-OS turns an x86 or x64 machine into a Linux network appliance for securing and optimizing network traffic. Its combined functions include firewalling, IPsec VPN, web application security, content caching, antivirus inspection and traffic shaping. Install it on bare metal or as a virtual machine, including VMware, Hyper-V and Proxmox. Administrators can configure an appliance through a CLI or browser-based Web GUI; a Manager can centrally manage multiple Gateways. The firewall uses stateful packet filtering, NAT and PAT, and the maker says it blocks common attacks such as DoS, SYN flood and IP spoofing by default. URL filtering supports lists and regular expressions, with LDAP or AD/Kerberos authentication. The WAF offers generic and custom filters, IP reputation lists and antivirus scanning. WAN tools include HTTP compression and multi-WAN routing with automatic failover. The OS is free to use. Optional subscriptions cover URL blacklists and extended antivirus signatures; Standard and Premium support also require paid subscriptions.
