Site-to-Site VPN
Private network connects to another private network
Software on both networks, users do not need apps
Creating a secure tunnel between two private networks
Remote Access VPN
User connects to a private network
Software installed on both a private device and the private network
Connecting to a private network from your home or personal location
Cloud VPN
User connects to a company's applications, data, and files in the cloud
Accessible via a website or desktop/mobile application; No need for VPN infrastructure on user's end
Secure access to both the company’s cloud and data center-based applications and data
SSL VPN
Devices establish a secure remote access VPN connection with a web browser
Modern web browser or client applications that enable direct access to networks. There are two primary types: VPN portal and VPN tunnel
Enterprises use SSL VPNs to enable remote users to securely access organizational resources and to secure the internet sessions of users
Double VPN
Use of two VPNs simultaneously, though practically challenging
Specialized software configuration or utility, but often results in conflicts
Enhanced security through multiple VPN layers, although challenging to implement properly
Link between two or more distinct networks, such as a company's main network, and its satellite office networks.
Secure connection of the off-site users to securely connect to company's main data center, encrypting all user data transmitted and received.
It creates a virtually private connection using a tunnel between the enterprise's network and a distant user.
This is achieved by encrypting the data, rendering it indecipherable to potential interceptors. Users can interact with their company's network as if they were on-site, ensuring safe data transfer without the concern of external interference or data breaches.
Remote user accessing internal networks using VPNaaS via a VPN tunnel through a private cloud setup.
Cloud VPN, sometimes referred to as hosted VPN or VPN as a service (VPNaaS), is a VPN approach tailored for cloud environments. This VPN allows users to securely access a business's resources, data, and applications in the cloud through a web interface or a dedicated app on desktop or mobile.
Unlike conventional VPNs that necessitate specific infrastructure at the user's location, cloud VPNs integrate seamlessly into a company's cloud distribution framework. One significant benefit of cloud VPNs is rapid worldwide configuration and deployment.
SSL VPN with a remote user connected through an SSL/TLS tunnel, passing a firewall to an SSL VPN gateway, linking to servers.
An SSL VPN, or Secure Sockets Layer virtual private network, allows remote users to connect to private networks in a secure manner. It employs the SSL security protocol, or its successor, the Transport Layer Security (TLS) security protocol, to ensure the encrypted transmission of data between the user's device and the VPN gateway. This encryption safeguards the integrity and confidentiality of data, ensuring that unauthorized entities cannot intercept or alter it.
It does not require specialized VPN client software on users' devices but it uses standard web browsers.
There are two types of SSL VPNs:
SSL Portal VPN In this model, users access a single webpage, or portal, which provides links to other private network resources. By visiting a specific website and entering credentials, users can initiate a secure SSL connection. This portal then grants access to designated applications or network services, as predefined by the organization.
SSL Tunnel VPN This variant is more comprehensive, enabling users to securely access multiple network services, not just those that are web-based. It establishes an encrypted tunnel under SSL, allowing for the secure access of various resources. To function optimally, SSL Tunnel VPN might require browsers equipped with additional applications, such as JavaScript or Flash.
Double VPN setup with data traveling encrypted through multiple VPN servers before reaching the internet.
A double VPN is more of a configuration versus a type of VPN technology. This setup involves channeling user traffic through two sequential VPN servers, providing two layers of encryption. In standard VPN use, data flows from the user's device to a single VPN server and then to the destination online. Using a double VPN configuration, the user's data is first encrypted and sent to an initial VPN server. Then it's encrypted again and directed to a second VPN server before reaching its final online destination.
While the double VPN method heightens security by adding an extra layer of encryption, it can also lead to slower connection speed due to passing through two separate servers and dual encryption processes.
