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

"The product works fine and I have never had any problems with it."
"The product's initial setup phase is easy."
"The most valuable feature of FortiClient is its high security level."
"The most valuable features of FortiClient are its VPN capabilities and its use as an anti-malware and anti-spam solution."
"It works well with the Fortigate Firewall."
"I use the tool to connect server to an ISP Data Center."
"FortiClient is very easy, useful, and practical."
"Fortinet FortiClient provides several benefits such as saving time, saving money, and improving security."
"It is stable."
 

Cons

"There is lagging in some of the authentication tools to support the newer versions, this is happening because they are not supported."
"Initially, the support was very poor."
"Fortinet FortiClient could improve the connection because sometimes it drops."
"Technical support is awful. Their online response time is not prompt. They should not respond after four or five days. Their support guys are not competent enough. Small issues are taking time."
"I heard that Fortinet is going to enhance the firmware to have mobile versions. One is like Linux long-term support SCS and one with new features, but there is no support here. We spoke with the vendor multiple times, and they said that they will release these features soon."
"The solution could add data to the endpoint."
"I don't think FortiClient is bad, but it's very buggy. We ran into some issues with the EMS, which amounted to more than 10 cases last year."
"The features of Fortinet FortiClient could be improved."
"The scalability could be a bit better."
 

Pricing and Cost Advice

"The price is okay and competitive."
"The solution is more cost efficient than Cisco, as FortiGate tends not to charge for the client license, which allows one to make free use of whatever is supported on the device."
"The pricing is reasonable."
"I don't have the licensing schema for the VPN solution because we just purchased the VPN gateway."
"The solution's scalability is inexpensive."
"It is not that expensive. It was within the range. A dollar per user per month is nothing."
"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."
"FortiClient is quite reasonably priced."
