CacheGuard-OS vs Comodo Internet Security

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.

Comodo Internet Security is a Windows security suite that combines antivirus protection, a packet-filtering firewall, host intrusion prevention, and automatic isolation for unknown files. Its Auto Sandbox runs unfamiliar files in a separate environment. The firewall can block unauthorized inbound and outbound connections, manage which programs can access the internet, and hide computer ports. Secure Shopping isolates browser sessions and includes keylogger prevention, screen-capture blocking, and SSL certificate inspection; it can also run applications such as email clients, password managers, spreadsheets, and VPN clients in that environment. The product describes cloud antivirus scanning, behavior analysis, and whitelisting, alongside malicious-website filtering with custom block lists. Comodo lists a free plan and paid plans from $29.99/yr. Its guide lists Windows 10, 8, and 7, and says versions 12.0.0.6882 and later do not support Windows XP or Vista. Support resources include Comodo Support, an online help guide, and a user forum.
