VPNs are usually used for remote access by people who work from home or other locations outside the office. They can connect to the company’s internal network securely, which means that sensitive data remains confidential. VPNs use various protocols to establish secure and encrypted tunnels between the client device and the server.

What are the Benefits of Using a VPN?

There are many benefits of using a VPN, including:

Enhanced Security: VPNs use encryption to keep your data anonymous and secure from hackers, spies, and other malicious actors.

There are three main types of VPNs:

Remote Access VPN:

Remote Access VPNs are the most common type of VPN used by individuals and small businesses.

Remote Access VPNs use an encrypted tunnel to protect users’ data and identity from unauthorized access.

Site-to-Site VPN, also known as network-to-network VPN, connects two or more networks securely over the internet. Site-to-Site VPNs are commonly used by enterprises to connect their branches or regional offices with the main headquarters.

Cloud VPN:

Cloud VPN is a type of VPN that uses cloud-based technology from a service provider to connect securely to the internet. Cloud VPNs are easy to deploy, flexible, and scalable compared to other types of VPNs. Cloud VPNs are ideal for small businesses that do not have their IT team or require secure remote access to cloud-based resources.
