Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

Web filtering and traffic balancing have improved security for SMBs but threat insight still needs work
I assess the machine learning capabilities of SonicWall TZ in proactive threat detection to not be at the level of other vendors such as Palo Alto Networks, Fortinet, and Check Point. It is somewhere in between, so I would not recommend it for a large enterprise-level organization to rely on because it is not at that level. SonicWall TZ's content filtering service is reliable. We have used it, but it is not very reliable compared to brands such as Fortinet, Palo Alto Networks, or Check Point. What could be improved about SonicWall TZ is the threat intelligence, which by far is not at the level of vendors such as Fortinet, Palo Alto Networks, and Check Point. Their threat intelligence needs to be improved, as does the GUI, which is not as user-friendly compared to devices such as Fortinet. They could learn from their competitors by making the product more user-friendly. The product interface is not that user-friendly. By adopting a more user-friendly GUI, improving threat intelligence, and enhancing the available guides would be beneficial. In my understanding, in some cases, the KB articles and knowledge articles were not that efficient. They were useful, but they could have been more precise with the knowledge base articles. They need to provide more information about SonicWall TZ, specifically more documentation and more troubleshooting articles. Other than the threat intelligence and the user-friendly GUI, there are no other additional features that I can think of for SonicWall TZ in the future or at least in the next release to make it more competitive.

User has benefited from stable performance and effective completion of security tasks
I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

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

Pros

"Using this product makes the VPN seamless and almost invisible to me in the sense that I don't have to think about it."
"The initial setup is straightforward."
"Web filters, particularly web application controls, grant us the ability to regulate user access effectively."
"The solution's application control is very powerful."
"Fortinet FortiGate is scalable for our users. Right now, we have almost 70 users. We do not have any plan to increase our usage of FortiGate. For maintaining the firewall solution, one staff member is enough."
"I would rate the scalability of this product a nine out of ten because it is highly scalable. We have not had problems with customers in terms of scalability."
"Fortinet FortiGate positively provides my clients' organizations with a high return on investment."
"I find that Fortinet FortiGate is pretty easy to use and integrated, offering many features in one box at a decent price compared to other enterprise vendors."
"The product is easy to deploy."
"SonicWall TZ is stable."
"The solution's VPN is very good for stability and detecting threats."
"We like the central interface and we like the security features; additionally, we use SonicWall with VPN connectivity and we have had no problems with SonicWall all these years."
"It is used as firewalls are normally used and performance has been outstanding."
"The most valuable feature is the user-friendly navigation."
"The solution is priced fairly and competitively."
"The most valuable feature of SonicWall TZ is the double authentication, where it asks for one password and again asks for a four-digit code, which changes every 30 seconds."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"This is a capable appliance and the standard features work well for us."
"The cost is very low."
 

Cons

"The firewall engine is not so strong as of now, in my opinion... My second concern is that, while they have Zero-day vulnerability and anti-malware features, the threat engine needs to be strengthened, its efficiency can be increased."
"Technical support is a little slow and needs to be improved."
"I don't like that anything more than very basic reporting is not included."
"The license renewal process, annual renewal price, and the web application firewall features should be improved."
"The product needs to drastically improve its reporting capability."
"I would like some automated custom reporting."
"I feel that the reporting needs to be improved."
"One of the weaknesses of the solution is something we noticed, especially after comparing the tool with SD-WAN features, since, unfortunately, in a massive scale size environment, the solution is not good. I"
"In general, the company needs to think contingently and integrate more security options."
"The user support could be improved because you have to go outside and get that kind of support."
"I would like to see lower antivirus pricing."
"You need to be a certificate holder to set it up and configure it. It's really important because it looks easy, but it is complex."
"The marketing of SonicWall has to be increased. Currently, when it comes to firewalls, most people go for Cisco and Palo Alto."
"The price could be better for us in Bolivia."
"The product needs more free SSL VPN user licenses as the current offering is limited."
"I find that the user interface for the product configuration needs improvement."
"Sometimes it reboots when you least expect it, and that's the main issue."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Although manageable, the user interface is a little bit slow and could be improved."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"There is a subscription-based model to use Fortinet FortiGate. We pay annually for the solution along with the support. If you want to have all the updates, and security patches you will need to renew your support."
"Fortinet FortiGate IPS' licensing is quite simple to understand."
"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."
"I would rate the pricing a five out of ten"
"Fortinet prices are around $600 for the small 40F model, and for licenses, the simplest option is about $300 for a year. They sell licenses that can last for 1, 2, 3, or 5 years."
"The pricing is flexible."
"I rate the price of Fortinet FortiGate SWG a seven and a half out of ten since it is not a cheap solution, though I feel it is a good product for the money one pays."
"On a scale of one being cheap and ten being expensive, I rate the tool's price as an eight."
"Its price is very high, which makes it difficult to convince the clients to buy this solution."

"The price is fair for the solution for the quality you receive."
"The solution is moderately priced, where it's neither cheap nor expensive."
"Its pricing is okay as compared to other solutions."
"The product is not expensive, but it is not cheap."

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
