Cybersecurity is evolving, and the traditional idea of “trusted internal networks” no longer holds. Zero Trust Network Access (ZTNA) offers a new paradigm: “Never trust, always verify.” With ZTNA, every user, device, and application is treated as potentially untrusted—even if they’re already within your network.
How It Works
Consider your company as a castle. In the past, once someone entered, they could move freely inside. ZTNA changes this model by enforcing that every single “room”—like OneDrive, Outlook, or SharePoint—requires separate permission. Security checks act like guards that verify identity at each step, and users are only allowed access to what they specifically need.
Key Principles of ZTNA
- Every user and device must prove their identity.
- Access is granted according to the principle of least privilege, ensuring that users can only reach necessary resources.
- The system continuously monitors user behavior to spot anything unusual.
- Being inside the network no longer equates to inherent trust.
Why ZTNA Matters
By adopting ZTNA, organizations protect against internal threats such as compromised accounts. It provides robust security for remote work and cloud service access. Furthermore, when something goes wrong, ZTNA limits the impact of cyberattacks by restricting how far attackers can penetrate the network.
Microsoft 365 in Action
Imagine an employee working from home, needing access to Outlook or SharePoint. With ZTNA in place, they must first confirm their identity through multi-factor authentication. The system then verifies whether they are using a devices with proper security settings and evaluates the context of the login—where, when, and how it’s happening. Access is granted only to what’s needed for their tasks, and their behavior is continuously monitored. If anything seems off, access can be blocked or flagged.
Even if credentials are compromised, attackers cannot freely move through Microsoft 365 resources—every step is verified, and access stays tightly controlled.
