Zero Trust Network Access
Why Zero Trust Network Access?
Hybrid working has become the norm. Employees work from home, on location, at client sites, and on the move. A security model that relies on network location as proof of identity no longer fits that reality. Zero Trust Network Access gives employees secure access to exactly the applications they need, regardless of location, while attackers attempting to piggyback on a stolen session or stolen credentials are blocked.
At the same time, organizations with ZTNA demonstrably meet the requirements of NIS2, BIO, and other frameworks that call for risk-based access control and demonstrable security measures.
Our approach
- 1
Access policy and device compliance
We implement conditional access policies (context-dependent access rules) that grant access based on user, device compliance, location, and risk level, using Microsoft Entra ID as the identity foundation. We link Intune device compliance to that policy, so that only managed and up-to-date devices get access to business applications.
- 2
Setting up application access per user group
We set up application access based on roles and least privilege (access limited to what is strictly necessary), so employees only have access to what they need for their work.
- 3
Reducing VPN dependency
Where VPN is replaced by ZTNA, we carefully guide the migration so employees transition seamlessly to the new access method without loss of productivity.
- 4
Monitoring and anomaly detection
We link access events to Microsoft Sentinel, so anomalous patterns are flagged immediately and placed in context with other security signals.
- 5
Adoption and communication
We support employees through the transition to ZTNA with clear communication and, where needed, brief instructions, so the change in access method doesn't become a barrier.
What does Zero Trust Network Access deliver?
Secure, seamless access
Employees who have secure and seamless access to applications, regardless of location or device.
Smaller attack surface
A smaller attack surface because access is limited to specific applications instead of the entire network.
Demonstrable compliance
Demonstrable security measures that align with NIS2, BIO, and other compliance frameworks.
Less VPN, more monitoring
Less dependence on VPN infrastructure and its management burden, with immediate flagging of anomalous access behavior via integrated monitoring.

FAQ
What is the difference between Zero Trust and Zero Trust Network Access?
Zero Trust is the overarching security principle: always verify, never trust implicitly. Zero Trust Network Access is the specific application of that principle to network access: access to applications based on identity and context, rather than network access via VPN. ZTNA is one component of a broader Zero Trust architecture.
Can we run VPN and ZTNA side by side for a while?
Yes, that's the usual approach. We migrate step by step, per user group or application, so employees aren't suddenly left without access. VPN is only switched off once ZTNA is fully set up and validated.
How long does a ZTNA implementation take?
An initial ZTNA implementation for an enterprise environment typically takes four to eight weeks, depending on the number of applications, user groups, and how far along the identity infrastructure already is. We start with a phased plan that delivers value immediately, so not everything needs to be converted at once.
