I mainly use FortiClient for the VPN connection from my home to the company where I work. It is a VPN client easy to use, configure and maintain.
It is constantly updated and with the option of VPN consumes few resources of the laptop.
FortiClient is not only based on a thin VPN client but also integrates a security suite of the Fortinet brand. You can choose what option to install as if it were modules.
These modules are antivirus, firewall, web filtering, application firewall, FSSO, FortiSandbox, SSL and IPsec VPN access.
Each section is optional at the time of installing the application and does not require in certain cases the use of a Fortigate in the network, since the same software offers all the benefits as if it were a business fortigate.
The points that highlights that FortiClient in my personal appreciation is web filtering and application firewall that adds a plus in a free software, has nothing to envy to premium security suites.
As a negative point of the program is that if you want to have all the benefits of the application, that is, all modules require a computer with good computing and memory capabilities, since it consumes a lot of resources to keep the computer safe in all the senses.
From the rest the software develops correctly.
More than problems to resolve, we have chosen to use FortiClient only for SSL and IPsec VPN access, as each company team uses its security (antivirus) tool.
