Frequently Asked Questions
What is the difference between site-to-site and remote access VPNs?
A site-to-site VPN permanently links two networks, while a remote access VPN connects an individual user to a network. Each suits different needs and security controls.
How does an IPsec VPN work?
IPsec negotiates keys in phase 1 and then builds secure tunnels for traffic in phase 2, providing encryption and integrity. It is widely used for site-to-site links.
What is the difference between IPsec and SSL VPNs?
IPsec works at the network layer and usually needs client software, while SSL/TLS VPNs work over HTTPS and are easier to use remotely. This free Codelivly room covers both.
