What is an SSL VPN?

An SSL VPN, or Secure Sockets Layer Virtual Private Network, is specifically designed to provide secure remote access to network resources through the use of the Secure Sockets Layer protocol. This protocol encrypts the data transmitted between the client and the server, ensuring that sensitive information is protected as it travels across potentially insecure networks, such as the Internet.

One of the key features of an SSL VPN is that it allows users to connect to a private network securely without needing to install additional client software, as many devices have web browsers that can handle SSL connections. This flexibility makes SSL VPNs particularly useful for accessing corporate networks from various devices, including laptops, smartphones, and tablets.

While the other options touch on different aspects of VPN technology, they do not accurately define the unique characteristics of an SSL VPN. For instance, the option mentioning IPsec relates to a different VPN technology often used in site-to-site VPNs rather than the browser-based access that SSL VPNs often provide.
