Introduction
The modern enterprise is becoming increasingly more complex to secure, given the increasing popularity of trends like remote work, hybrid clouds, and BYOD. The traditional approach of securing a network perimeter no longer works in today’s environment, where the perimeter is blurred or almost non-existent. A new approach is needed to accommodate these trends and guarantee improved security posture, which is where Zero Trust comes in. Zero trust is a security
framework that empowers organizations to secure their networks, applications, and data by eliminating the inherent trust that came with older access solutions such as VPN and a firewall-based network perimeter.
Zero-trust Network Access (ZTNA) is needed because the traditional security model, where users are granted access to the network based on their role within an organization, no longer works in today’s multi-cloud and remote work world. Zero-trust network access (ZTNA) protects an organization’s networks, apps, and data from malicious actors by limiting access and verifying user identity at every step. A zero-trust security model denies access to an enterprise’s digital resources by default. It grants authenticated users and devices tailored, siloed access to only the applications, data, services, and systems they need to do their jobs.
The benefits of ZTNA include increased security, reduced complexity, and improved compliance, but it requires the enterprise to invest in proper solutions to support this technological and cultural shift.
