Challenge: Large financial institutions are regularly in need of applications that can securely connect their sites between data centers, disaster recovery centers, and also international locations.

Background: In this specific instance, one financial institution was in need of a solution that would encrypt data when transmitting information from the United States to their regional offices in Europe. Like many large institutions, this specific financial institution had a very large bandwidth for this type of requirement.

Typically SONET OC-12, OC-48, or even OC-192 is deployed across the Atlantic for these applications. Many solutions also utilize DWDM optical infrastructure as the basic transport. How does a financial institution cost effectively secure such a large connection?

Solution: To meet the security requirements and reduce overall network complexity, the financial institution selected Thales' Layer 2 SONET encryptors to encrypt all confidential data transmitted between sites in both the United States and Europe. Layer 2 is the data link layer of the protocol stack defined by the Open System Interconnection (OSI) model for data communications, which establishes the physical connection between local telecommunications devices and their associated remote destination.

A Layer 2 encryption solution is easy to deploy and the Thales solution is interoperable with most SONET and DWDM vendors. The Thales Datacryptor SONET solution encapsulates all the protocols crossing the link, thus significantly reducing network complexity and minimizing latencies.

Ease-of-use and quick setup made Thales' Layer 2 encryption solution a natural choice for this highspeed requirement, protecting the confidentiality and integrity of sensitive data over point-to-point WAN connections. The financial institution selected Thales e-Security as their "vendor-of-choice" because of these attributes, as well as its leadership in the data encryption industry, its overall financial strength and its capability to support both the current and future needs of the financial institution.
