Layer 2 Tunneling Protocol (L2TP) enhances data security and is ideal for heightened security in Site-to-site configurations. Point-to-Point Tunneling Protocol (PPTP) is outdated and less secure. Secure Socket Layer (SSL) and Transport Layer Security (TLS) are common in remote access VPNs. OpenVPN offers high security for both remote access and Site-to-site setups. Secure Shell (SSH) suits remote access but requires close supervision. Wireguard, a newer protocol, emphasizes efficiency and safety, gaining traction for Site-to-site connections. Choosing the best protocol depends on business needs, setup preferences, risk models, traffic load, and data accessibility. For remote access, consider Wireguard, L2TP, SSL/TLS, and OpenVPN, while Site-to-site choices depend on hardware compatibility.

When to Use a VPN

Using a Virtual Private Network (VPN) can be a valuable tool in various online scenarios, providing enhanced privacy, security, and accessibility. Here are some situations when using a VPN is particularly beneficial.
