Zero Trust Network Access
Zero Trust Network Access (ZTNA) is built around one simple principle: never trust anyone by default. Every access request is verified based on who the user is, which device is being used, and the circumstances under which access is requested. This gives employees the freedom to work from anywhere while ensuring that your organization maintains control over who has access to what.
Why Zero Trust Network Access?
Hybrid working has become the norm. Employees work from home, on site, at client locations 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, ZTNA allows organisations to demonstrably meet the requirements of NIS2, BIO and other frameworks that call for risk-based access control and verifiable security measures.
Our approach
- 1
Toegangsbeleid en apparaatcompliance
We implement conditional access policies (context-based 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 only managed, up-to-date devices can access business applications.
- 2
Applicatietoegang per gebruikersgroep inrichten
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
VPN-afhankelijkheid afbouwen
Where VPN is replaced by ZTNA, we guide the migration carefully, so employees transition seamlessly to the new way of accessing applications without any loss of productivity.
- 4
Monitoring en afwijkingsdetectie
We connect access events to Microsoft Sentinel, so anomalous patterns are flagged immediately and placed in context alongside other security signals.
- 5
Adoptie en communicatie
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, seamless access to applications, regardless of location or device.
Smaller attack surface
A smaller attack surface because access is limited to specific applications rather than the entire network.
Demonstrable compliance
Verifiable security measures that align with NIS2, BIO and other compliance frameworks.
Less VPN, more monitoring
Less reliance on VPN infrastructure and its management overhead, with immediate detection of anomalous access behaviour through 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 part of a broader Zero Trust architecture.
Can we run VPN and ZTNA alongside each other for a while?
Yes, that's the usual approach. We migrate step by step, by user group or application, so employees are never suddenly left without access. VPN is only switched off once ZTNA is fully configured 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 and user groups, and how far the identity infrastructure is already in order. We start with a phased plan that delivers value straight away, so not everything has to be converted at once.
