CER & NIS2 Advisory
Turn Regulatory Obligation Into Operational Resilience
The Critical Entities Resilience Act (CER-laki 310/2025) and the NIS2 Directive set a new baseline for protecting Finland's critical infrastructure. Sonarix helps you meet it — and use it as the foundation for a genuinely stronger security posture, not just a compliance exercise.
Why This Matters Now
CER and NIS2 apply across all eleven of the EU's critical sectors, not only the handful most commonly discussed. That creates real urgency and, often, real budget — but many organisations don't yet have an internal roadmap for meeting the requirements, let alone extending them down into their own supply chains.
We deliberately lead with regulatory and governance credibility rather than a technology pitch. Critical infrastructure operators are, rightly, cautious about new vendors and new hardware. A grounded conversation about compliance obligations opens doors that a sales pitch cannot — and it's usually the more useful conversation to have first.
Our Four Building Blocks
Security Planning
A structured gap analysis of your organisation against CER and NIS2 requirements.
Training & Workshops
Leadership and staff-level programmes, including scenario-based exercises and role-based training.
Situational Awareness
Technology-enabled visibility into physical and cyber-physical threats, drawing on our Monava and sovereign edge compute solutions.
Ongoing Service
Continuous training and care, so your resilience keeps pace with a changing regulatory and threat landscape.
How We Work Together
Step
What Happens
1. Management Briefing
A focused session for leadership on what CER and NIS2 actually require, and where the organisation stands today.
2. Current-State & Gap
Workshop
A structured assessment identifying the specific gaps between current practice and the regulatory baseline.
3. Targeted Pilot
A focused, real-world pilot addressing the highest-priority gap identified.
4. Ongoing Training & Care
A continuing programme of training and support to keep resilience current.
Built for the Whole Supply Chain
CER and NIS2 place new resilience obligations not only on critical entities themselves, but on their subcontractors and suppliers as well. Most advisory providers in Finland focus their attention on the critical entity alone. Sonarix has built a dedicated readiness and training programme specifically for subcontractors and suppliers — closing a gap we consistently see left unaddressed in the market.
Scenario-Based Training
Our workshops use structured, scenario-based exercises with clearly defined roles, so teams can practise decision-making under pressure before they ever need to do it for real — for both leadership and operational staff.
Sector Coverage
The CER Directive covers eleven sectors: energy, transport, banking, financial market infrastructure, health, drinking water, waste water, digital infrastructure, public administration, space, and food production, processing and distribution. See our Sectors page for how Sonarix's work applies across them.
