Remote Access VPN vs Site-to-Site VPN

Voice over Internet Protocol, or VoIP, allows customers to achieve flexible and affordable phone service anywhere in the world. This is because VoIP calls are transmitted via the public Internet. But, some businesses require additional security for calls that are delivered over the Internet. For these businesses, VPN solutions are the ideal option.

Businesses that require additional security for calls delivered over the public Internet often turn to VPN (virtual private network) solutions. But if you've done any research on virtual private networks, you know that there are several different types of solutions available, including remote access VPN and site-to-site VPN. Each solution has its own benefits, depending on the type of business that you are running.

In this post, we'll walk through the differences between remote access VPN solutions and site-to-site VPN solutions so that you can make the right choice for your business.

What is a remote access VPN?

Remote access VPN solutions connect individual users to private networks. In a remote access VPN situation, every user needs his or her own VPN client.

When the user is connected to the network via the VPN client, the software encrypts the traffic before delivering it over the Internet. The VPN gateway, which is located at the edge of the targeted network, then decrypts the data and sends the information to the appropriate host inside the private network.

Who uses remote access VPN solutions?

Remote access VPN solutions are ideal for teleworkers who need secure access to a main network. It's also a great solution for employees who travel frequently, or work remotely on a regular basis.

What is a site-to-site VPN?

Site-to-site VPN solutions enable businesses to connect and transport data using encryption and other security protocols. To securely relay information across the Public Internet, the VPN uses a security method called IpSec to build an encrypted tunnel from the provider's network to the customer's site. This secure path looks and acts like a private connection with additional security, even though it still uses the Internet to deliver voice calls and other forms of data.

Who uses site-to-site VPN solutions?

Since site-to-site VPN solutions connect entire networks to each other, they are ideal for businesses with multiple locations. For example, a site-to-site VPN can provide secure VoIP traffic from one office branch back to a company's headquarters.

Enabling Secure VoIP Communications

VPN connections allow businesses who need the additional security of an encrypted connection to leverage VoIP for full-featured phone services over the Internet. These businesses still enjoy all the benefits of VoIP communications, including lower costs, a wide range of features, and hosted operations of solutions provided in the cloud.
