Behind the reason we chose SonicWall for my company is it has excellent packet analysis of normal and SSL encrypted traffic, application intelligence visualization and control, multiple Gigabit Ethernet LAN and WAN ports, flexible configuration and redundancy options. Outstanding antivirus scanner, advanced security structures. Content Filter, anti-virus and security are worthy. Easy to set up and use modest user interface. Plenty of security features to satisfy the most demanding security administrator.
Room for Improvement:
Cutting-edge options can be complex to manage, add-on security services increase the cost. No DNS proxy aptitude for Split-Brain or Split horizon setup. Very weak DHCP server options, only basics. Poor documentation. Limitations in the core design such as the inability to scan outbound HTTP traffic. Load balancing is not stable. VPN setup ambiguous, to say the least. Pricing options are somewhat complex. Documentation will require downloading various manuals in PDF format.
