Understanding the 6 Main Types of VPN Connections

Cloud VPN

Cloud VPNs connect on-premises systems or users securely to cloud-based environments such as AWS, Azure, or Google Cloud. They enable seamless communication between company data centers and cloud resources over encrypted tunnels. This is ideal for hybrid networks or organizations running distributed workloads that require flexibility and scalability.

IPsec VPN

IPsec (Internet Protocol Security) VPNs operate at the network layer, encrypting and authenticating IP traffic. They are commonly used for site-to-site VPNs between offices or router-to-router connections, as well as for secure remote access. IPsec ensures both confidentiality and integrity by protecting data packets during transit.

SSL VPN

SSL (Secure Sockets Layer) VPNs work at the application layer and provide encrypted remote access through a web browser. They require no additional client software—users simply log in via HTTPS. SSL VPNs are perfect for mobile and remote workers who need to access internal tools securely from any device.

Client-Based VPN

Client-based VPNs rely on software installed on the user’s device. The VPN client authenticates and encrypts all traffic to the company network, allowing users to access shared files, printers, or internal apps as if they were physically in the office. This is the most common configuration for remote corporate employees.

Site-to-Site VPN

Site-to-Site VPNs link entire networks—such as branch offices and headquarters—so devices across both locations can communicate as one network. This setup is permanent and automated, with routers or firewalls at each end handling encryption and decryption transparently.

Remote Access VPN

Remote Access VPNs allow individual users to connect securely to a company’s private network from anywhere. Through strong encryption and identity verification, they protect sensitive traffic even on public Wi-Fi. These are the most common VPNs used by remote workers, freelancers, and IT support teams.
