Internet site-to-Web site VPNs
Site-to-web-site VPNs are typically employed by companies to attach several Workplace spots or branch workplaces to a central community. Such a VPN generates a protected tunnel in between the several websites, letting them to share sources, knowledge, and purposes securely, as if they ended up all part of precisely the same community community.

SSL/TLS VPNs
SSL/TLS VPNs, also called World-wide-web-centered VPNs, use the Secure Sockets Layer (SSL) or Transport Layer Safety (TLS) protocols to ascertain a safe link. This sort of VPN is frequently applied to deliver distant usage of Website-based applications or resources, and it can be accessed through a web browser with no need for specialised VPN shopper program.

Cell VPNs
Cellular VPNs are created to perform seamlessly with mobile devices, such as smartphones and tablets.
