Designing secure access with ZTNA

Zero Trust Network Access (ZTNA) is often introduced to modernize access to applications. However, without changes to the underlying design, these deployments can continue to reflect older models of trust.

In many cases, ZTNA tools are deployed in environments that still treat network location as a primary signal of trust. This means the tools may be new, but the underlying approach continues to rely on broad, network-based access rather than more granular, context-driven decisions.

Our new guidance explains how organisations can design and implement ZTNA in a way that better aligns with zero trust principles and supports modern network environments.
