SonicWall TZ

We were using the Cisco ASA but there are lots of security features that are missing in these devices. SonicWall is a combination in advanced security and advanced routing. You can easy to use this firewall.

I have chosen SonicWall TZ over the Fortigate as more ease of use and support been outstanding.

We chose the Sonicwall TZ250 because it has reliability in the Dell Sonicwall brand. It is a reliable product, with excellent support and warranty with face-to-face service should the need arise. It is cheaper than the competition, does not take up rack space, does not heat up, and it is easy to configure the equipment through its very good graphical interface.

We like it is a small, portable, and has many features. I have confidence in the brand a long time. Support was also a differential to make the decision.

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.

Our previous firewall, from Xyzell, couldn't handle the bandwidth that video files needed within the internal LAN, so we looked at alternatives. SonicWall came recommend by a different IT professional for its solid performance and good documentation. We further researched the TZ lineup, and decided on a model that would fit our traffic needs.
In practice, the interface is a bit more difficult to use than Xyzell, but due to Xyzell's lack of documentation, and support of a 2 year old model, SonicWall has been a much more pleasant experience. Performance wise, there is a night and day difference between the two.

because it is multiprotocol, has continuous support and is also economical

SonicWall and WatchGuard are both fine appliances, but I am accustomed to the Barracuda NG. The Barracuda Control Center is so powerful and useful that it beats out the other two. SonicWall does a great job of dividing up firewall rules and NAT policies, but this is a preference among engineers.

SonicWall TZ is a much better product. Easier to administer and use and much more elaborate in its rules. I would choose it over Watchguard any day.

Costs, features and ease of use were the determining factors. The UI alone outweighs the CLI from the ASA and SRX, features were easier to understand and licenses were more easily obtained.
