IP VPN: The Foundation for Your Communications

An IP VPN is the network foundation on which your communications are built. Enterprises can now converge multiple network into a MPLS-enabled IP VPN, allowing them to use a single network to support their voice, data and other business applications. IP VPNs provides the foundation that connects your corporate headquarters, data centers, branch offices, and remote and mobile workers to each other, and to the applications they need to be productive.

To be effective, employees need access to your mission critical applications while working from home, from the office and while on the road. An IP VPN helps you stay connected using an access method you choose, while delivering the performance your applications need.

IP VPN Considerations

Choosing the right kind of network can be critical to the success of your business. Here are some areas to consider:

Do you need a scalable, reliable foundation for all your applications?

VPNs were once just used to support data. But today's VPNs support data, voice, video, wireless and other applications to support all aspects of your business. And VPNs scale easily, so they are ready to grow when you are. Because you use the same infrastructure for all your locations, managing your network can be simpler, too.

Do you have workers in remote and home offices?

It's common today for companies to have multiple branches across the globe, or to have employees working on the road or in home offices. No matter where they are, employees need the same reliable, high-speed remote access to applications and other resources that they have in the main office.

VPN services support that connectivity for all applications - voice, video, data and more. This means your employees and others using your network have the same experience whether they're in the office, across town or somewhere across the globe.

Is your network ready for the future?

VPNs accommodate today's technologies and simplify the ability to adopt new technologies and applications with their change-ready architecture. VPN services are flexible enough to adapt to almost any new features or functions you need to add, and scalable so that your network can grow to meet your future needs.
