Vasu Gala - PeerSpot reviewer
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Network security has strengthened with next-generation firewall features and cost savings
I primarily use SonicWall NSA as a next-generation firewall for network security architecture. It is especially used for securing business operations with networks of more than 250 people SonicWall NSA's most valuable features are its SD-WAN and a system RTBI that blocks all attacks. These…
Alexander Azikov - PeerSpot reviewer
A robust appliance that is reasonably priced and straightforward to set up
Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The user interface is relatively easy. The devices are easy to deploy and figure out when you have experience with other security appliances."
"We've found the solution to be pretty stable."
"It enables our organization to become more productive. Also, it protects our NEtWare from viruses and malware."
"Fortinet FortiGate is one of the most solid and secure firewalls as long as you keep it up to date. The price is right; it's not very expensive."
"SSL-VPN is very useful for us and has been very reliable."
"The most valuable feature of FortiGate is FortiView which provides proactive monitoring."
"Whenever we raise a complaint with FortiGate, their response and resolution times are minimal."
"The scalability is good in Fortinet FortiGate."
"The functionality is the same whether it is on hardware or a virtual appliance. The interface is the same. It's nice that it's standardized."
"This product has kept us safe and we haven't had any breaches."
"With the deployment of the SonicWall NSA solution, we never suffered a problem due to invasion or contamination of any kind."
"Compared to Cisco, SonicWall NSa is much easier to configure."
"It is a brilliant product. It is a Unified Threat Management (UTM) system. It has got about 11 security services that take care of your perimeter security. It takes care of any kind of cyber threats that could come in. It takes care of creating VPNs between two SonicWalls instantly and very easily. It has got spyware in it as well as a firewall. It has also got a gateway antivirus and an application firewall that can block things from outside."
"Content filtering reduces the load on the available bandwidth and restricts employees from using distracting websites on the job, which leads to more productive hours."
"The solution can scale."
"The firewall feature is most valuable since my work is to analyze if there is any potential attack. SonicWall NSa gives the perfect analysis."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"This is a capable appliance and the standard features work well for us."
"The solution can scale well."
 

Cons

"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."
"A sandbox would be good in order to be able to inspect the emails containing spam and be able to validate the emails that contain malware, prior to delivering to the customer."
"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."
"It can be a little bit more user-friendly in terms of policy definition and implementation. It seems a little bit complicated, and it could be simplified."
"We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable."
"They could simplify their deployment process, especially when customers have existing devices."
"Pricing for it is a bit high. It could be cheaper."
"For Fortinet FortiGate, their code development would definitely be something they need to improve on to reduce vulnerabilities that need to be patched."
"It needs to be more monolithic, and more details in the analytical tools offered would be appreciated since it is not yet mature."
"Overall, Im satisfied with SonicWall NSa, but it would be better if they could add a small terminal to each device. This would help me deal with certain issues by running a small bot onto any PC."
"We have used other solutions such as pfSense and Linux native firewalls. I prefer SonicWall NSa but if you are going to use something for an enterprise you need another solution."
"SonicWall does not support DynDNS, yet this is an important feature for smaller companies that do not have a static IP address."
"We still get phishing emails that manage to come through from time to time."
"SonicWall NSa's reporting could be improved."
"The only thing that we would want would be single-pane management, which it has, but the GMS is not very good. It's purely the management of multiple devices for multiple customers, that's the only thing that it's lacking."
"The ongoing service fees are high."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
"Although manageable, the user interface is a little bit slow and could be improved."
 

Pricing and Cost Advice

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."
"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."
"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."
"The pricing is fair."
"The price of Fortinet FortiGate is the lowest in the market."
"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."
"The price is fair compared to the other competitors."
"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."
"SonicWall still is only a dollar or Euro per gigabit. This means, of the IPsec, it's the cheapest solution."
"While I don't know the exact amount off the top of my head, I would estimate the licensing package was about $15,000 to $20,000 a year."
"The pricing is lower and better than other products."
"The solution is cheaper than others."
"The price of SonicWall NSa is expensive."
"There is a license required for this solution and you can purchase a one, two, or three year term. Typically businesses choose the one year subscription and then later choose the three year licensing option if they are satisfied."
"Compared to Fortinet and Cisco, SonicWall NSa is a cheaper solution."
"You need their analyzer to properly generate reports. This is an expensive, licensed feature, with a complex application or appliance back-end."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
