Let’s see the difference between Site to site VPN and Remote access VPN, which are given below:
| S.NO | Site to site VPN | Remote access VPN |
|---|---|---|
| 1. | In site to site VPN, IPsec security method is used to create an encrypted tunnel from one customer network to remote site of the customer. | In remote access VPN, Individual users are connected to the private network. |
| 2. | Site to site VPN does not need setup on each client. | Remote access VPN may or may not needed setup on each client. |
| 3. | Site to site VPN does not require every user to initiate the VPN tunnel setup. | Remote access VPN require every remote access user to initiate the VPN tunnel setup. |
| 4. | Site to site VPN supports IPsec technology. | While Remote access VPN supports SSL and IPsec technology. |
| 5. | In site to site VPN, multiple users are not allowed. | In remote access VPN, multiple users are allowed. |
| 6. | A site-to-site VPN, meanwhile, connects individual networks to each other. | A remote access VPN connects remote users from any location to a corporate network |
| 7. | Site-to-Site VPN is widely used in Office LAN users of branch offices that need to connect to servers located at the headquarters. | Remote Access VPN is used for Roaming users who want to access resources/servers securely. |
Conclusion:
Site-to-site VPN and remote access VPN serve different purposes and have different requirements. Site-to-site VPNs are used to connect multiple networks together, while remote access VPNs are used to provide individual users with secure access to a private network. The choice between these two types of VPNs depends on the specific needs of the organization and its users.
