Which technology does FortiGate use for secure remote access?

FortiGate employs Virtual Private Network (VPN) technology to facilitate secure remote access. VPNs create a secure and encrypted connection over a less secure network, such as the internet. This allows users to send and receive data as if their devices were connected directly to a private network, thus ensuring data privacy and integrity. VPNs can provide robust encryption options, authentication methods, and secure tunneling protocols, making them ideal for organizations needing to enable remote access while maintaining security.

The other options focus on different functionalities that are not related to secure remote access. Remote Desktop Protocol (RDP) is a protocol used primarily for remote access to desktop environments but does not inherently provide the encryption and secure tunneling needed for secure connections over public networks. File Transfer Protocol (FTP) is primarily used for transferring files and lacks built-in security measures. Hypertext Transfer Protocol (HTTP) is used for transmitting data over the web but, without enhancements like HTTPS, does not offer encryption or secure access, making it unsuitable for secure remote access scenarios.
