What is IPSEC/SSL VPNs?

IPSEC (Internet Protocol Security) and SSL (Secure Sockets Layer) VPNs (Virtual Private Networks) are technologies used to create secure, encrypted connections over a public network like the internet. IPSEC operates at the network layer, providing security for all traffic passing through the VPN tunnel. SSL VPNs, often referred to as TLS VPNs since SSL has been largely superseded by TLS, typically operate at the application layer, securing specific applications or web traffic. They are commonly used to enable remote access to corporate networks, ensuring data confidentiality and integrity during transmission.
