In the previous article we talked about how virtual private networks work. Virtual private networks have become the need of the hour for modern business to ensure highest levels of safety.
Virtual Private Networks, abbreviated as VPNs, are a technology that allows users to connect to the internet securely and privately. A VPN creates a secure and encrypted connection between the user’s device and the internet, effectively creating a private network within a public one. It allows users to send and receive data securely and anonymously, protecting their privacy and preventing others from intercepting their data. Additionally, VPNs bypass geographic restrictions on internet content and make websites and services accessible irrespective of the region.
Today, we shall throw light on the different types of VPNs. So let us begin.
Different Types of VPNs
VPNs come in several different types, each designed to serve specific purposes and address various needs. Below are some of the most common types of VPNs briefly described.
- Remote Access VPN: This type of VPN allows individual users or employees to connect to a private network from a remote location. Remote access VPNs are particularly used for telecommuting and accessing company resources as if they were physically in the office.
- Site-to-Site VPN: Site-to-Site VPNs, also known as network-to-network VPNs, are used to connect entire networks or multiple branch offices of a company over the Internet in the most secure way. It enables seamless communication and data exchange between geographically dispersed locations.
- Intranet-Based VPN: An intranet-based VPN is typically used within an organization to interconnect various departments or teams. It operates within the organization’s private network and is often used to facilitate access for remote employees.
- Extranet-Based VPN: Extranet VPNs extend the functionality of intranet-based VPNs to include external parties such as business partners, suppliers, or customers. They allow controlled access to specific parts of an organization’s network for authorized external users.
- Client-Based VPN: Client-based VPNs are software-based solutions that individuals or employees install on their laptops or smartphones to establish secure connections to a remote network. They are commonly used for remote work, providing encrypted access to company resources.
- SSL/TLS VPN: Secure Sockets Layer(SSL) and Transport Layer Security(TLS) VPNs use standard web browsers to establish secure connections for remote access to web-based applications and services. SSL and TLS VPNs are convenient because they don’t require any specialized client software.
- OpenVPN: OpenVPN is an open-source VPN protocol known for its strong security and flexibility, often used for both site-to-site and client-based VPN connections and is available on a wide range of platforms.
- IKEv2/IPsec VPN: Internet Key Exchange version 2 (IKEv2) combined with IPsec is a robust and efficient VPN protocol. It’s known for its quick reconnection capabilities, making it suitable for mobile devices that frequently switch between networks.
- WireGuard: WireGuard is a relatively new and lightweight VPN protocol known for its speed and simplicity. It is gaining popularity due to its robust security features and efficiency required by modern businesses.
- Mobile VPNs: Mobile VPNs are usually designed for mobile devices optimized for maintaining a secure connection as devices switch between various networks, such as Wi-Fi and cellular data.
The choice of VPN type depends on the specific use case, security requirements, and the devices or networks involved. It’s essential to select the appropriate VPN type and configure it correctly to ensure the desired level of privacy and security.
