What is an SSL VPN?

An SSL VPN refers specifically to a Virtual Private Network that leverages Secure Sockets Layer (SSL) encryption to create secure connections over the internet. This type of VPN allows users to access private networks remotely while ensuring that the data transmitted is encrypted, safeguarding it from eavesdropping and unauthorized access.

The primary function of an SSL VPN is to provide secure remote access for users, often through a web browser, rather than requiring specialized client software. This convenience, combined with robust security mechanisms offered by SSL, makes SSL VPNs popular for organizations looking to protect sensitive data while allowing flexible work arrangements.

When considering other options, a method for sending emails does not align with the purpose of a VPN, which is primarily about securing network communications rather than email services. While a firewall plays a crucial role in network security, it does not specifically pertain to the concept of a VPN. Lastly, a protocol for routing data packets does not capture the focused functionality of SSL VPNs, as it doesn't emphasize secure remote access or the encryption aspect that SSL brings to VPNs.
