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

"I find it very easy to configure and also very stable."
"The connection speed is fast, I can connect quickly at any time, and there are never any interruptions to the FortiClient connection, so I could easily code into the client's server with that connection with no lag."
"It's very stable."
"It is a fantastic product; its overall security is valuable, and we are very impressed with the web filtering and the application firewall it provides."
"Our customers are generally looking for a solution that works well and they get it with FortiClient."
"Previously, we worked with OpenVPN and Palo Alto, and we switched to Fortinet FortiClient because of the advantage that the free VPN connection device has helped us with implementation and adds value to the solution."
"The initial setup is very good."
"The solution has helped increase staff productivity by approximately 15 percent."
"It is stable."
 

Cons

"One area that could be improved is cost, but you've got to pay for what you get."
"The solution has some stability issues on the user side but is improving."
"The pricing of the solution should be less expensive."
"One challenge we faced was with the installation."
"I'm hoping they change the management system."
"There should be more frequent releases or updates."
"I haven't found that the solution does anything amazing; there is nothing special about it."
"We do not use the solution every day and there are times when the new users have trouble reconnecting."
"The scalability could be a bit better."
 

Pricing and Cost Advice

"The licensing fee varies with what one is trying to accomplish. It can range from being free to costing several hundred thousand dollars per year."
"It is not that expensive. It was within the range. A dollar per user per month is nothing."
"The cost per port is very less as compared to the other technologies."
"I rate the product's pricing a seven out of ten."
"Licensing was free up to ten users and after that, it was pretty reasonable."
"Generally, Fortinet is not cheap. The features that are available for free are only for FortiClient VPN clients, not other solutions. It includes web security, antivirus, and one more feature."
"Fortinet FortiClient comes free with the purchase of the FortiGate solution. There is a license required for this solution. You later can upgrade from the free version which will allow more endpoints. The cost of the license subscription is based on how many endpoints you require."
"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."
