Senior Technical Manager at Flexaccel
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

"Fortinet FortiClient offers a vulnerability test feature, allowing us to monitor end-user devices. This includes ensuring necessary updates, such as Windows updates, are not overlooked."
"This is a solid and stable solution."
"The performance of FortiClient is impressive."
"It's a good solution."
"The return on investment was very reasonable. It was low cost and it functioned, so the return on investment was excellent."
"It is a stable solution."
"Remote users connect to the office using FortiClient, where they can access business URLs through a VPN tunnel configured on the FortiGate firewall."
"The initial setup of this solution is easy."
"It is stable."
 

Cons

"While I cannot think of new features to add, it would be nice if the reports were improved, to have these sent automatically."
"Cloud services are very expensive for us."
"FortiClient needs improvement in restricting user information and ensuring more secure customer data to better protect source code and reduce the risk of security breaches."
"When we change our endpoint, we have to connect again, which means having to enter our credentials and permissions."
"The tool needs to improve its web filtering feature. Its support quality needs improvement. We speak different languages, and this can create misunderstandings."
"The support can be improved. They have room to improve by deploying more support resources."
"Sometimes users stay on the old version of FortiClient."
"Sometimes users stay on the old version of FortiClient. When new releases are not compatible, I need to reinstall newer versions, which can be problematic."
"The scalability could be a bit better."
 

Pricing and Cost Advice

"The solution is not expensive. We need more discounted rates in Pakistan. The price of the solution could be reduced to be more affordable for the solution."
"The price is okay and competitive."
"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."
"The pricing is reasonable."
"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."
"The pricing is good because you get and end-to-end security solution in one package price."
"Anyone can download this product for free, but you have to have a FortiGate gateway that you are connecting to."
"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."
