Strategic Resilience

Know exactly where your risks are.
And what to do about them.

NIS2, DORA, ISO 27001, CRA: not paper compliance, but a clear plan that works. AI-assisted risk analysis delivers in days what traditional consultants take weeks to produce.

From CISO-as-a-Service to security awareness. Independent, vendor-neutral and directly actionable.

What are Security Advisory Services?

DEFION's Security Advisory Services help organisations translate compliance obligations into working security. From NIS2 and DORA readiness assessments to CISO-as-a-Service and security awareness training. Every engagement combines AI-assisted analysis with the judgement of senior consultants. You get a concrete action plan with prioritised steps. Not just a report full of findings. Typical duration: 2–6 weeks depending on scope.

Why organisations rethink how they buy security advice

The big-four report sits in a drawer

Two hundred pages of "should consider" and "is recommended". No priorities, no owners, no deadlines. So nobody acts. And the next audit shows the exact same findings.

NIS2 and DORA feel like a paper tiger

You know what they are; you don't know what to do tomorrow. Between legal text and operational execution is a gap most advisors don't close. And the board is personally liable.

A full-time CISO doesn't fit our budget

But you do need someone thinking strategically at board level. A compliance officer or IT manager is not a substitute. They lack the mandate and the scope to weigh security trade-offs across the organisation.

Why DEFION Advisory

Four traits that set us apart

No learning curve on your invoice. No vendor agenda. A roadmap your team can act on Monday.

Senior consultants, no juniors

Senior-only

Our NIS2, DORA and ISO engagements are run by experts with 10+ years of experience. No junior fees, no skill-building on your invoice. What lands in the report is lived experience, not a textbook.

Roadmap, not report

Directly actionable

Prioritised actions with owners, deadlines and lead times. Something to live by, not something to read. Your team knows what to do Monday. Without an interpretation session.

Vendor-neutral advice

No vendor stake

No kickbacks, no preferred partner, no disguised product sales. Our advice is worth half as much if we also sell you something. So we don't. There are other parties for that.

Available after the report

Ongoing partnership

We stay on for the implementation. Through CISO-as-a-Service, executive sparring or strategic advice. You're not on your own once the deck is delivered.

Frequently Asked Questions

FAQ

What is a NIS2 Readiness Assessment?
A structured analysis of your current security posture against NIS2 requirements. You get a gap analysis and a prioritised roadmap. Typical duration: 2–4 weeks.
What does CISO as a Service cost?
It depends on the number of days per month. DEFION provides senior security leadership from 2 days per month. You pay for expertise, not overhead.
How does DEFION differ from large consultancies?
We go technically deeper and move faster. No juniors running your assessment. No vendor agenda. And we stay available after the report is delivered.
Does my organisation need to comply with NIS2 now?
The implementation deadline in the Netherlands is 1 July 2025. If you fall within scope, you need to start now. Board members are personally liable.
What if I am not sure whether NIS2 applies to us?
We determine that in the first conversation. Based on your sector, size and activities, we assess whether you qualify as essential or important.
