What are the three types of VPN supported by Sophos XG Firewall?

The three types of VPN supported by Sophos XG Firewall are IPsec, SSL VPN, and L2TP.

IPsec (Internet Protocol Security) is widely used for securing Internet Protocol communications by authenticating and encrypting each IP packet in a communication session. This makes it suitable for site-to-site connections as well as remote access.

SSL VPN, on the other hand, utilizes the SSL (Secure Sockets Layer) protocol to provide secure remote access to users. It is particularly useful because it can pass through most firewalls and works seamlessly with web browsers, allowing for easier client access without the need for specific client software.

L2TP (Layer 2 Tunneling Protocol) combines the best features of PPTP and L2F (Layer 2 Forwarding), offering stronger security than PPTP by supporting IPsec for encryption. L2TP is often utilized when a more secure and scalable solution for remote access is required.

These three types of VPNs encapsulate a variety of needs for companies, from site-to-site connectivity to remote user access, and are integral to the Sophos XG Firewall’s capabilities.
