Zero Trust Architecture

The days when a firewall at the edge of the network offered sufficient protection are over. Employees work from anywhere, applications run in the cloud, and an attacker who gets in once can move around unhindered. Digital Survival Company designs Zero Trust architectures that fit the reality of enterprise organizations 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 privileges as possible per user and session.

That breaks the classic assumption that everything inside the network is safe. If an attacker does get in, they can't move around unhindered (move laterally): access is re-verified everywhere, supplemented where needed with extra separation between applications (microsegmentation).

Our Zero Trust Architecture approach

  1. 1

    Identity and device compliance as the starting point

    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 get access to business applications and data.

  2. 2

    Network segmentation and microsegmentation

    We design network segmentation that limits lateral movement, supplemented with microsegmentation for environments where applications require extra isolation.

  3. 3

    Least privilege access

    We design role-based access with minimal privileges per user and per application, and build in a review process to periodically test and revise access rights.

  4. 4

    Continuous monitoring and detection

    We design the integration with Microsoft Sentinel so that deviating access patterns are flagged immediately and placed in context with other security signals.

  5. 5

    Step-by-step implementation

    Zero Trust isn't a big bang but a growth path. We design a roadmap that starts with the most critical risk areas and covers the entire environment step by step.

What does Zero Trust deliver?

Consistency

Consistent security for employees who work from anywhere, without compromising on ease of use.

Compliance with security requirements

Demonstrable compliance with the security requirements of NIS2, BIO, and other frameworks that call for risk-based access control.

Architecture that scales

A security architecture that scales with the cloud environment and new applications, without manual adjustment every time.

Safety

A foundation that makes AI use safer, because access rights are strict and auditable.

FAQ

  • Is Zero Trust also feasible for organizations without a large security team?

    Yes. Zero Trust is an architectural principle, not a product you implement all at once. We design a step-by-step approach that starts with the highest impact, such as conditional access and MFA, and expands from there. That's feasible for organizations 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 support for compliance obligations.

  • Can you also take care of implementing the Zero Trust design?

    Yes. After the Design phase, we guide the Build phase, where we actually implement the design in your cloud and workplace environment, and the Run phase, where we continuously manage security monitoring and access management.
