Unisys Stealth®

Working both inside networks and remotely, Stealth reduces attack surfaces by creating dynamic, identity-driven microsegments called communities of interest, separating trusted systems, users and data from the untrusted. Encryption between endpoints cloaks assets from unauthorized users, while Dynamic Isolation™ capabilities quickly isolate devices or users at the first sign of compromise. As a result, authorized users and devices within microsegments are cloaked from attackers and data exfiltration is blocked.
