When should I configure a site-to-site VPN?

Summary

Advantages of Site-to-Site VPN

One key advantage of site-to-site VPN is the enhanced security it provides. With IPsec protocols, all traffic is encrypted in transit through the VPN tunnel, ensuring that data remains secure. Additionally, the site-to-site VPN tunnel only allows traffic from one end to the other, preventing any attempts to intercept the traffic from the outside.

Differences Between Point-to-Site and Site-to-Site VPN

A site-to-site VPN connection enables applications running in an entire external network to seamlessly access Azure SQL databases. On the other hand, a point-to-site VPN connection is specific to an individual client computer that is external to Azure.

Benefits of Site-to-Site IPsec VPN

Using a SASE (Secure Access Service Edge) allows companies to provide branch offices and retail stores with access to the cloud or data center. It also enables quick identification of users, devices, and applications, as well as consistent application of security policies across multiple locations.

Limitations of Site-to-Site VPN

One limitation of site-to-site VPN is limited scalability. As VPN only provides point-to-point connectivity, a unique connection is required for each pair of connected sites, resulting in the number of VPNs growing exponentially with the number of sites.

Types of Site-to-Site VPN

There are two types of site-to-site VPN:

1. Intranet-based VPN: Connects several offices of the same company
2. Extranet-based VPN: Connects the office of one company to another company

Difference Between Site-to-Site VPN and Remote Access VPN

Site-to-site VPN is commonly used in office LAN users of branch offices who need to connect to servers located at the headquarters. Remote access VPN, on the other hand, is used by roaming users who want to securely access resources or servers.

Difference Between IPsec and Site-to-Site VPN

In site-to-site VPN, the IPsec security method is used to create an encrypted tunnel from one customer network to the remote site of the customer. In remote access VPN, individual users are connected to the private network, and there is no need to set up on each client.

Challenges for VPN

Scalability, performance, and security can all become challenges with remote access VPN.

When Not to Use a VPN

There may be cases when you need to turn off your VPN, such as when accessing local content or devices, or when accessing streaming services that are unavailable in the countries you are virtually connected to.
