Overall Satisfaction with SonicWall TZ

I have made the decision to deploy Dell SonicWall TZ 400 firewall as our primary outside firewall. We are using it as the main Internet security solution, content web filtering engine, and a VPN gateway. The device is responsible for managing all WAN and LAN traffic. Sonicwall TZ 400 gives us opportunities to use LT2P and SSL VPN connections for our employees and IPSec VPN connections to our AWS infrastructure and remote IT services.
  • Great security services package under Comprehensive Gateway Security Suite (GW AV, anti-spyware, intrusion prevention, app control, etc.).
  • Flexible customization of access rules, NAT policies, objects, etc.
  • Geo-location filtering cut a lot of bad and just suspicious traffic.
  • Ease of management and administration.
  • Good hardware and firmware performance (after an upgrade to the most recent version).
  • Low or competitive cost compared to other vendors.
  • Had issues with performance (CPU) until we upgraded the firmware to the most recent.
  • Would like to have more flexibility on logs sending and alerting.
  • Routing is a little bit over-complicated.
  • VPN access allowed employees to be more flexible and being able to get internal resources from anywhere.
  • Lower licensing price compared to competitors saved some money.
  • Protecting from unnecessary connections increased performance and uptime.
  • One of the firmware versions caused CPU performance degradation that slowed down the Internet speed which caused issues in the call center.
Pretty much similar functionality. SonicWall TZ400 compared to ASA 5506 has better hardware performance. SonicWall licenses cost less money which makes it better for the same needs and functionality. However, the Cisco ASA Internet unity and knowledge base are bigger then SonicWall and sometimes gives you the target solution faster.
SonicWall TZ (400) is a well-suited solution for small and mid-size companies. Very flexible and easy to configure and manage (at least for IT specialists). A lot of documentation on the Internet. A very good solution for quick VPN configuration for employees and VPN tunnels between branches or networks. For large companies, I would recommend having several devices to split roles or get a more suitable solution.
