Remote access has become seamless and secure while deployment remains simple for our users
Performance could be improved today. People are now moving toward SASE, which stands for Secure Access, Secure Edge Solution. Fortinet also has that offering, which would be easier since it operates through the cloud, acting as a first line of defense. When the user connects to the internet, they connect to the cloud first for posture assessment and monitoring before connecting to the outside world. The impact is significant because nowadays people are adopting SASE. During COVID time, many users were trying to connect back to their office, causing the performance or CPU utilization of the firewall to increase tremendously, which slowed down performance. I have not worked with endpoint telemetry in Fortinet FortiClient that could have been helpful for threat mitigation.

Responsive support, fair pricing, and good performance
It's going very well. We are happy with its capabilities. The performance is good overall. We like that we can change the connection if you don't like the speed, for example, is limited. You can find the right one to get the performance you require. It is easy to set up. It is stable. Technical support has been helpful and responsive. Pricing is fair. It was not too expensive.

Quotes from Members

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

Pros

"From an application perspective, this solution is stable."
"Fortinet FortiClient helped me reduce the attack surface by providing the ability to centrally view what is happening, allowing me to view everything from a single pane of glass, making it very easy now to react or respond based on what I'm seeing on the network."
"It is very powerful."
"FortiClient has good signatures, good protection and, up until recently, it integrated really well with our firewall."
"The solution's TNA feature blocks devices from entering the network that do not meet compliance protocols."
"It’s easy to use."
"We find the VPN features valuable."
"It's got a very friendly user interface."
"It is stable."
 

Cons

"We'd like to be able to properly encrypt the data more effectively."
"The documentation could be improved."
"The endpoint side of FortiClient needs improvement, specifically the agent-based endpoint, which requires enhancements in detection and additional features to reduce bugs."
"The pricing is not cheaper compared to competitors. For price satisfaction, it rates at seven out of ten and could be improved."
"It has a horrible performance. It is one of the most unstable VPNs I have ever used."
"Occasionally, the solution may provide a slow connection. In addition, there may be initialization and authorization issues that one may need to take care of while using the solution."
"While I cannot think of new features to add, it would be nice if the reports were improved, to have these sent automatically."
"FortiClient's encryption key could be stronger so that it's not broken too easily."
"The scalability could be a bit better."
 

Pricing and Cost Advice

"FortiClient is costly."
"The price is okay and competitive."
"The solution's scalability is inexpensive."
"Its pricing is good. One thing that has always attracted us to the Fortinet range of products is that their pricing is very competitive. Our particular licensing is on a yearly basis. However, as part of this project, we did pre-purchase three years of maintenance and support at a fairly significant discount."
"As a technical team member, I am not responsible to look into the pricing matters. These aspects are typically handled by the management team, who have the authority to obtain the necessary licenses based on certain established principles."
"I don't know it by heart, but it is comparable to other solutions. It is based on the number of clients. It is probably 50 Euros per year per client. It greatly depends on the number of clients you're handling because the more clients you are ordering it for, the cheaper it will be."
"Fortinet requires you to buy a lot of product in order for you to have proper protection."
"Licensing was free up to ten users and after that, it was pretty reasonable."
