Zero Trust Architecture
The days when a firewall at the edge of the network offered sufficient protection are over. Employees work everywhere, applications run in the cloud, and an attacker who gets in once moves on unimpeded. Digital Survival Company designs Zero Trust architectures that fit the reality of enterprise organisations in a pragmatic, step-by-step way.
Why Zero Trust Architecture?
Zero Trust is a security model in which no access request is automatically trusted, not even from within the corporate network. Every user, every device and every session is verified based on identity and context, with as few permissions as possible per user and session.
This breaks with the classic assumption that everything within the network is safe. If an attacker does get in, they cannot move around unimpeded (laterally): access is re-verified everywhere, supplemented where necessary with extra separation between applications (microsegmentation).
Our Zero Trust Architecture approach
- 1
Identity en apparaatcompliance als vertrekpunt
We design identity-based access control via Microsoft Entra ID, with conditional access policies that grant access based on user, device, location and risk level. Device compliance via Intune is linked to this, so only managed and up-to-date devices gain access to business applications and data.
- 2
Netwerksegmentatie en microsegmentatie
We design network segmentation that limits lateral movement, supplemented with microsegmentation for environments where applications require extra isolation.
- 3
Least privilege toegang
We design role-based access with minimal permissions per user and per application, and build in a review process to periodically assess and revise permissions.
- 4
Continue monitoring en detectie
We design the integration with Microsoft Sentinel so that anomalous access patterns are immediately flagged and placed in the context of other security signals.

Stapsgewijze implementatie
Zero Trust is not a big bang but a growth path. We design a roadmap that starts with the most critical risk areas and gradually covers the entire environment.
What does Zero Trust deliver?
Consistency
Consistent security for employees who work anywhere, without compromising on usability.
Compliance with security requirements
Demonstrable compliance with the security requirements of NIS2, BIO and other frameworks that call for risk-based access control.
An architecture that scales with you
A security architecture that scales with the cloud environment and new applications, without needing manual adjustment every time.
Safety
A foundation that makes AI use safer, because access rights are strict and auditable.

FAQ
Is Zero Trust also achievable for organisations without a large security team?
Yes. Zero Trust is an architectural principle, not a product you implement in one go. We design a step-by-step approach that starts with the highest-impact measures, such as conditional access and MFA, and expands from there. This is achievable for organisations of any size, even without large internal security capacity.
How does Zero Trust relate to NIS2 and BIO?
Zero Trust principles align directly with the requirements of NIS2 and BIO in the areas of access security, risk management and demonstrable measures. A Zero Trust design therefore also provides strong substantiation for compliance obligations.
Can you also take care of implementing the Zero Trust design?
Yes. After the Design phase, we guide the Build phase, in which we actually implement the design in your cloud and workplace environment, and the Run phase, in which we continuously manage security monitoring and access management.
