​McAfee Validates Unmatched Security of Unisys ClearPath®​ OS 2200 Software​​​

​Leading cybersecurity company deems secure scalable environment for high-volume enterprise computing as "exceptional" in resource protection

BLUE BELL, Pa., July 6, 2017 Unisys Corporation (NYSE: UIS) today announced that, after a rigorous two-month evaluation, leading cybersecurity company McAfee, Inc. has rated the Unisys ClearPath® OS 2200 operating environment "highly secure" and the secure control it affords over resources in Unisys ClearPath Forward™ systems "exceptional."

The McAfee finding provides further expert validation of the unmatched security of the ClearPath OS 2200 operating environment – a secure, scalable software environment for high-volume enterprise computing. Along with its counterpart ClearPath MCP, OS 2200 is the only operating environment on the market in which user data has never been forcibly extracted.1

"This validation not only spotlights the unsurpassed security of ClearPath OS 2200, but also underlines Unisys' commitment to continue enhancing a secure software environment that affords clients maximum protection for their long-term investments in strategic applications," said Tarek El-Sadany, senior vice president and chief technology officer, Unisys.

McAfee unit Foundstone Services conducted the multi-phase evaluation early in 2017 for both the OS 2200 operating system and Apex, a web-based application for management and administration of the OS 2200 environment.

After the testing, the Foundstone team reached the following conclusion:

. . . Throughout testing, architecture and design discussion with Unisys it is evident that the OS 2200 operating system has had security design principles such as "deny by default" and "least privilege" as a foundation throughout its evolution. . . The granularity of management control over system resources within the Security Level 1 systems under review as part of the Foundstone engagement was exceptional.

OS 2200 is also designed to provide a secure environment for program execution which protects against attempts to inject and execute malicious code. OS 2200 access control capabilities allow administrators to employ several means of identifying users and controlling their system access. . . OS 2200 provides an integrated technology stack in which all system components, including resource allocation, system monitoring, and account management have all been designed, implemented, and tested to collaborate and promote system-wide security.
