What is the main advantage of using Secure Socket Layer Virtual Private Network (SSL VPN) in web mode?

The main advantage of using Secure Socket Layer Virtual Private Network (SSL VPN) in web mode is that it does not require the installation of client software on the user's device. This feature allows users to quickly access the VPN through a standard web browser, making it highly convenient, especially for deployment in environments where users may not have administrative privileges to install additional software or where quick access is required.

This characteristic is particularly beneficial for organizations that support a bring-your-own-device (BYOD) policy or need to provide remote access to users who are on the go. By using web mode, users can connect to the network securely from virtually any device that has a web browser, simplifying the user experience and minimizing setup time.

The other options, while they may describe characteristics associated with different VPN solutions, do not capture the unique convenience that comes with the web mode of SSL VPN, which is key for many users.
