Cybersecurity Assessment
Do you know how resilient your organization really is — or do you just think you do?
✓ Independent assessment against recognized frameworks (ISO 27001, NIS2, DORA)
✓ Measurable maturity score with a concrete priority map
✓ Reporting suitable for management, board, and supervisors
Many organizations have implemented security measures. But they lack an integral, independent view of their actual security maturity. The result: investments without prioritization, compliance gaps that remain undiscovered, and uncertainty towards management and supervisors about the organization's true status.
A DEFION Cybersecurity Assessment provides that view. Objective, structured, and immediately usable.
The problem: security without an integral overview
Organizations invest in isolated measures — an EDR here, a firewall upgrade there, an awareness training — but rarely see the whole picture. Without a structural overview, the following arises:
- Investments in low-impact measures while core risks remain uncontrolled
- Insufficient alignment between IT reality and what management believes is arranged
- Compliance activities that meet legal requirements but do not improve security
- Fragmented responsibilities — no one "owns" the security position integrally
- No demonstrable basis for audit, supervisor, or cyber insurer
- Missing insight into how your position compares to industry peers
A cybersecurity assessment brings structure, measurability, and direction.
What you get with a DEFION Cybersecurity Assessment
Our assessments combine strategic analysis with technical validation:
✔ Current security level — Analysis of existing measures, governance, processes, and technical setup
✔ Risk identification — Systematic assessment of technical and organizational risks, prioritized by impact
✔ Maturity score — Measurable level on people, process, and technology against recognized models (NIST CSF, ISO 27001, CMMC)
✔ Compliance gap analysis — Testing against NIS2, DORA, ISO 27001, CRA, or sector-specific frameworks
✔ Management reporting — Clear report for management, board of directors, and external regulators
✔ Priority map — Concrete ranking of improvements based on risk impact and feasibility
✔ Implementation roadmap — Phasing with ownership, timelines, and dependencies
No generic checklist. A substantiated, organization-focused tailored assessment.

What types of assessment does DEFION offer?
Security Maturity Assessment
Systematic evaluation of your security maturity based on recognized frameworks (NIST Cybersecurity Framework, ISO 27001, CMMC). You receive a measurable starting point and a clear growth path.
Risk Assessment
Identification and prioritization of your technical and organizational risks. Which risks are critical to your business operations? Where is the likelihood of incidents highest and the impact greatest?
Compliance Assessment
Structured testing against specific standards: ISO 27001, NIS2, DORA, EU Cyber Resilience Act, or sector-specific regulations. Focused on demonstrable compliance, not just ticking boxes on paper.
Technical Security Review
Evaluation of your architecture, configurations, network segmentation, and technical security measures. Identifies technical vulnerabilities that organizational assessments do not capture.
Threat Modeling
Identification of realistic attack paths given your organization type, sector, and threat profile. Which attackers threaten you, what do they want to achieve, and how would they do it?
OT Security Baseline Assessment
Assessment of your industrial environment's security maturity — specifically focused on OT architecture, segmentation, and the convergence of IT and OT. Relevant for manufacturing, energy, water, and transport sectors.
During the intake, we determine together which combination aligns with your objectives.
How an assessment at DEFION proceeds
-
Scope definition & objective
Together we determine the standards framework, the objective, and the involved stakeholders — IT, security, compliance, management, and any external supervisors. -
Documentation analysis
We review existing policy documents, architecture descriptions, risk registers, and previous audit reports. -
Interviews & technical validation
Structured interviews with key personnel, supplemented with technical checks to validate the actual situation — not just what is on paper. -
Scoring & prioritization
Maturity level is determined, risks are prioritized, and compliance gaps are identified. Findings are linked to business impact. -
Reporting & presentation
You receive a clear report — a technical version for IT and security, and an executive summary for management and supervisors. We present the findings in person and answer questions.

For which organizations is an assessment essential?
A cybersecurity assessment is indispensable for:
- Organizations with increasing compliance requirements (NIS2, DORA, ISO 27001, CRA)
- Boards that bear personal liability for security (NIS2) and need demonstrable insight
- Organizations that want to invest risk-driven instead of allocating budget intuitively
- Organizations that need audit assurance towards supervisors, insurers, or customers
- After an incident: understanding how it happened, and what must structurally change
- During mergers, acquisitions, or outsourcing: validating governance and security position before decision-making
- Organizations setting up a structured security program for the first time

“The sector and the partners we work with maintain increasingly high security standards for IoT-products and services. Protecting the privacy of individuals in the images and the sensitivity of the information the drones collect, such as on objects in critical infrastructure, requires our security to be airtight. With Defion, we are working with a professional partner who can support us at the right level. The collaboration also fits perfectly within our strategy to deliver reliable and secure drone technology to European customers.”
Benjamin van der Hilst Co-Founder & CEO

“New requirements from NIS2 for OT systems are increasing the focus on security. With Defion, we know we have the right expertise in-house to keep our systems secure. The collaboration was easy and pleasant; the specialists truly sat next to us rather than across from us. Thanks to their openness and expertise, we are working together toward the same goal: optimal security. This gives us the confidence to face the future.”
Alexander OdijkTeam Manager

“If you look at where we were ten years ago, we’ve made enormous progress. The sense of control is greater. With Security Assurance and MDR we have set up processes and control mechanisms that allow us to limit the impact of a potential attack. The collaboration also serves as a constant reminder to maintain focus on security and set the right priorities in that area. It keeps us alert and sharp. Moreover, Defion’s specialists are highly technical and passionate about their field. That clearly shows in their services.”

Frequently Asked Questions
How much does a cybersecurity assessment cost?
This depends on the size of your organization, the chosen framework, and the desired depth. An intake interview is free of charge. We provide an initial estimate within one business day.
How long does an assessment take?
Typically 4-8 weeks from intake to final report, depending on scope and availability of involved parties.
How does this differ from a pentest?
An assessment is strategic and organization-focused: we evaluate policies, processes, governance, and technical setup. A pentest is technical and exploratory: we actively try to exploit vulnerabilities. They are complementary — an assessment sets priorities, a pentest validates whether the defense works.
Can we share the report with our auditor or regulator?
Yes, and we recommend it. Our reports are prepared with external stakeholders in mind.
What if we have already had a previous audit?
We take previous reports as input and focus on what has changed since then and on blind spots that were previously missed.
Does DEFION also offer guidance on implementing recommendations?
Yes. We are happy to assist with priority planning and implementation support, including CISO as a Service for organizations that need structural security leadership.
Why DEFION — and not a large consulting firm?
Technical depth and strategic advice
Large consulting firms deliver compliance reports. DEFION provides technically validated insights supplemented with strategic advice — by specialists who also perform pentests and incident response.
Vendor-neutral and without a sales agenda
We do not sell products. Our recommendations are based on your interests — not on licensing opportunities.
IT and OT
Our assessors understand both IT environments and industrial OT architectures. In sectors where IT and OT converge — manufacturing, energy, water, transport — this is distinctive.
Born from twenty years of fieldwork
DEFION originated from Computest Security and Incide. Our assessors are also pentesters and incident responders. They not only know what is theoretically vulnerable — they know what attackers do in practice.
