Zero Trust
Zero Trust is a security model that was developed in 2009 as an alternative to older perimeter-based security models. Since then, Zero Trust has evolved beyond its original focus on securing the network and is now being adopted by private-sector technology executives and by international and US government agencies. It is based on the principle of “never trust, always verify” and requires continuous verification of every user, device, and network request. The core principles of Zero Trust include eliminating implicit trust, enforcing least-privilege access, implementing comprehensive security monitoring, attaching cloud security to cloud management, and harnessing cloud-native deployment, rearchitecture, and migration initiatives. The model ensures comprehensive control over access to data and resources, regardless of where they are located. Learn more about Zero Trust and how it can be applied to your organization through Forrester Decisions For Security & Risk.
