Leverage IPSec in a hybrid VPN

Provide exceptional protection for data with end-to-end encryption

Create a simple, highly secure VPN connection between remote users, satellite offices, or mobile employee and your network hub using IPSec tunnels.

IPSec is today’s most widely used encryption technology, and AT&T VPN Tunneling Service uses IPSec to create highly secure pathways that carry your data encrypted over public networks.

There are two main types of VPNs: (1) MPLS (Multiprotocol Label Switching), a solution that operates over a single carrier’s network, and (2) IPSec (Internet Protocol Security), which uses virtual tunnels to send encrypted data between sites over the public Internet.

Many organizations opt for a hybrid IPSec/MPLS solution. By connecting satellite locations to a centralized MPLS VPN via virtual tunnels, companies can benefit from the flexibility and reach of broadband as well as the quality of service offered by a managed MPLS solution.

Integrity checks help ensure that no one tampers with data in transit.

Authentication verifies that the user sending or viewing the data is authorized to do so.
