Unisys Brings 'Stealth' Enterprise Security to AWS Cloud

Patterson noted that Stealth originated a decade ago as part of a Unisys government project, and the company quickly realized its potential as a general use product. After several years of investment, Unisys brought it forth as a commercial product five years ago, and it now supports customers in the energy, public sector, U.S. Department of Defense, financial, retail, and healthcare sectors around the world.

In addition, Stealth on AWS allows organizations to extend entire workloads securely from data centers to the cloud; manage access via existing identity systems including Active Directory or LDAP; and easily add integrated supply chain partners to micro-segments without giving them broad access – at the packet level without any new hardware, firewall rules, or application changes.

Patterson says AWS has a lot of strong security built into its underlying framework. Yet, “Stealth helps users easily add layers of security that they control into their instances that run on top of AWS security,” he added. “This solution adds VM to VM encryption; extends micro-segments from the rest of their infrastructure directly into the cloud; lowers overall security management costs with identity-based management; and closes gaps between their data centers and the cloud with the use of a single security system where they can control their own encryption keys.”

Asked if there is any overhead associated with using Stealth, Patterson said: “Stealth works at the packet level, between layers two and three of the IP stack, which dramatically reduce any overhead normally associated with controls higher up the stack.  Additionally, our users report instances of improved performance since we greatly reduce the flow of unexpected packets that would otherwise need to be processed.”

Enterprises can acquire Stealth directly from the AWS Marketplace, where Unisys also offers an AWS Test Drive that enables organizations to access a private sandbox using Stealth. Using a step-by-step lab manual and video, they can learn more about Stealth and how it works, with no charges incurred as part of the AWS Free Tier.

Alternately, enterprises that want to dynamically extend their on-premise infrastructure to AWS can use Stealth’s “cloud bursting” capability, which automates the shifting of secure workloads directly into AWS.

Patterson told eWEEK that using Unisys Stealth has advantages over going private cloud.

"The public cloud holds intrinsic cost, scale, surge and agility advantages over building a private cloud on one’s own," he said. "By adding Stealth security on top of AWS to provide the additional security needed for many privately-controlled networks, users can now enjoy the business benefits of the public cloud without having to change their security scheme. Our new Extended Data Center option for Stealth makes it both easier and more agile than building your own private cloud."

Unisys Stealth for AWS offers two subscription choices: an hourly subscription for 25 cents per hour and an annual subscription for $1,300 per year. Every endpoint to be Stealth-protected requires a subscription.
