Unified security fabric has simplified multi-country deployments and strengthened threat response
FortiGate VM delivers exceptional performance and security with no degradation of service or protection (same features as the HW option). As part of the Fortinet Security Fabric, it extends across clouds and distributed locations, mitigating blind spots in virtual infrastructures. FortiGate VM can be rapidly deployed, managed through a centralized platform, and offers a range of purchasing options to suit every need. Also, FortiGate VM offers versatile deployment options across both public and private clouds, supporting all major public clouds including AWS, Azure, and Google as well as most hypervisors such as VMware, Hyper-V, and KVM. These deployments enable organizations to create scalable, high-performance firewalls that can be tailored to different virtualized environments and hyper-scale public cloud infrastructures. FortiGate VM integrates seamlessly with various infrastructure as code (IaC) tools such as Jenkins and GitLab, supporting security as code practices.

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

"High network throughput while providing leading edge network security technology for a competitive price.​"
"It gives all the features of a full-fledged firewall with great performance."
"The best feature of Fortinet FortiGate-VM is the deployment; I applied best practices for deployment with Fortinet FortiGate-VM by the VPN connection into the site, on-premise and cloud or hybrid for segmentation of level of security, the perimeter and inside zone."
"The solution is quite good; it is simple and fast."
"The most valuable aspect of the solution is the V-Scanner which is the monitoring software, as we are able to closely monitor the usages of individual users and see their usage habits and other items, including the data itself, which gives us quite a bit of visibility."
"The most valuable features of Fortinet FortiGate are the web filters, as we are using them mostly; our content is condition-based, so we are accessing the websites by using the web filters."
"Web filtering and the IPS functionality."
"The configuration, graphical interface and command line are easy to use."
"This is a capable appliance and the standard features work well for us."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
"The cost is very low."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
 

Cons

"The pricing is expensive."
"They could enhance the product's functionality for more comprehensive threat detection and mitigation, especially for large-scale deployments."
"We haven't attempted to scale the solution just yet. If we want to scale this solution we may have to look at other models. With certain requirements, we probably wouldn't be able to scale it so well as it is right now."
"In my experience, Fortinet FortiGate is not stable at all."
"It should have the SD-WAN feature. This would increase the number of features that are available in the box."
"The price of FortiGate-VM is high and should be more competitive."
"The solution's web-filtering configuration could be better."
"More monitoring should be included with Fortinet FortiGate-VM, in my opinion. It has a monitoring tool, but it could be improved."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"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. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
 

Pricing and Cost Advice

"Our license is yearly, but we're thinking of going monthly. I think it's somewhere around 100,000 for VM04. Nowadays, everyone wants to be a hacker, so we believe in security. That's why we also have third-party people that we involve to make sure that we're secure. I don't think the costs are too bad. You still want to get advice from people who worked in security for many years, so you add a third party. The third party also said they would give their share like 100K, or 200K or something like that, so I don't think it's too expensive for security. I think it just adds more trust."
"The price is expensive compared with other vendors, like Cisco and Huawei."
"I rate the product's pricing an eight out of ten."
"Installation does not require another license making it an inexpensive solution."
"I rate the product price a three on a scale of one to ten, where one is a high price, and ten is a low price."
"The solution could be better priced."
"​The basic pricing in Austria is OK, but asking for special offers, e.g., NPOs, NGOs, trade up, and/or trade in, is always useful.​"
"There is a need to make payments towards the licensing costs attached to the solution."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
