Which protocol does the Firebox use for secure VPN connections?

The Firebox utilizes Internet Protocol Security (IPsec) for establishing secure Virtual Private Network (VPN) connections. IPsec is a widely adopted suite of protocols designed to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session. It ensures the confidentiality, integrity, and authenticity of the data transmitted over the internet, making it a robust choice for secure VPN implementations.

This protocol operates at the network layer and provides end-to-end security without needing modifications to applications. By using IPsec, Firebox can efficiently manage secure communication channels, making it ideal for remote access and site-to-site VPN connections.

While other options like Secure Sockets Layer (SSL), Point-to-Point Tunneling Protocol (PPTP), and Layer 2 Tunneling Protocol (L2TP) offer their own methods for establishing secure connections, IPsec is preferred for its comprehensive security features and standardized support in many network infrastructures.
