Blue Coat has introduced data loss prevention (DLP) appliances to mirror its application delivery networking appliances.

A family of appliances that provide comprehensive DLP in a single integrated appliance have been introduced and integrate data loss protection for traffic on the network, including email and web content, and data at rest in databases or on servers with a unified management system.

Three new applications are available with facility for use by up to 250 users; up to 5,000; and up to 20,000. The company claimed it also creates a new agent for malware detection and adds another layer of defence.

Michael Cartsonis, senior manager of OEM at Blue Coat, told SC Magazine that in the past the company has protected what came into a network, and now with DLP it is protecting what goes out with a larger defence.

He said: “This is an appliance, easy and highly scalable. We are looking at multiple vendors and the solutions have to get full coverage with a simple appliance. It is a natural sophistication of the medium and a natural legal defence, and if something gets through and transfers out to phone home you have an extra layer of defence.

“It is a combination of multi-layered solutions, the system comes with network DLP, a checking capability with email and web management. This is all included and can scale up to multiple applications.

“You can have it on the network sniffing traffic and it gives visibility and then you can start to set policy. There is the potential for false positives, it depends on policy and the system and the finger printing of data which rules these positives. There is no perfect solution, but there are advanced solutions and there is 600+ file types and multi-language support. It is simple without complexity.”

The new appliances integrate with the Blue Coat ProxySG appliances using the secure ICAP protocol. Once connected, the ProxySG appliance enables the DLP appliance to inspect SSL-encrypted traffic and serve as the enforcement point to block, forward or encrypt sensitive information.

Andreas M. Antonopoulos, Nemertes senior vice president and founding partner, said: “Regulatory compliance, in addition to the high cost of responding to information leaks, is driving more and more companies to adopt data-protection solutions. However, many companies quickly discover that the cost and complexity of DLP solutions, added to the organisational and cultural challenges introduced by DLP, can lead to abandoned products or user backlash.

“Successful DLP projects are incremental in nature – they start off with a narrow set of well defined goals and build on success. In evaluating DLP solutions, companies should look for ease of use and flexible rules that support an incremental deployment.”
