In the modern digital landscape, conventional security measures fall short in defending against cyber threats, which necessitates that organizations embrace a Zero Trust Network approach. This model operates on straightforward principles: no user or device is trusted, whether they are within the internal network or external to it, and access is minimized based on verified identity. While these principles are easy to understand, the process of implementation can pose significant challenges, particularly when it involves costly and lengthy upgrades to current network systems that may deter organizations from transitioning to Zero Trust. However, Unisys Stealth offers a versatile cybersecurity solution that leverages identity-based encrypted microsegmentation to seamlessly convert your existing infrastructure—whether on-premises or cloud-based—into a Zero Trust Network. With Unisys Stealth, businesses gain access to a suite of products and services designed to enhance their security posture, ensure regulatory adherence, and safeguard their operations. This innovative approach empowers organizations to proactively address vulnerabilities while fostering a more resilient security framework.
