Security is a leadership responsibility
Article 5 of 5 in the series “When Security Fails – and Trust Breaks”
The Nordic region is among the most digitally advanced in the world. That is a source of pride, and a significant risk factor.
A recent survey of organisations across Finland and Sweden found that 54% had experienced at least one severe cyberattack in the past year. Nearly nine in ten expect the number of attacks to increase. Yet only 23% say their organisation is fully prepared for NIS2 and the regulatory requirements now entering into force.
The gap between exposure and preparedness is real. And NIS2 is unambiguous: responsibility for closing it sits in the boardroom.
This is the final article in the series. It draws together the threads from the four preceding articles and asks the question that determines whether the foundation is actually built: who owns the responsibility?
The Nordic gap – and why it is a leadership issue
The TEK Norge Nordic Cybersecurity Benchmark 2025 gives a concrete picture of where the region stands:
|
72 Finland |
69 Sweden |
66 Denmark |
64 Norway |
| Score out of 100 · TEK Norge Nordic Cybersecurity Benchmark 2025 (NyAnalyse, December 2025) | |||
The most striking finding is not the scores themselves, it is what lies beneath them. Even the highest-scoring countries in the region face a threat landscape that is outpacing their defences. Attacks on Denmark’s energy infrastructure, a fourfold increase in cyberattacks on Finland and Sweden following their NATO accessions, and Sweden leading all Nordic countries in ransomware incidents: these are not warning signs for the future. They are the present.
One observation from the benchmark deserves particular attention: a relatively low number of reported security incidents is not necessarily a positive sign. It may equally mean that attacks are not being detected. That is an uncomfortable, but important point for any leader.
The Nordic region has the talent, the infrastructure and the motivation to lead on cybersecurity. What is missing in too many organisations is ownership. And ownership starts in the boardroom.
Erik Ramstad, Head of Network, Infrastructure & Cybersecurity
What NIS2 actually requires of leadership
NIS2 is not primarily a technical requirement. It is a governance and leadership accountability requirement. What sets NIS2 apart from previous regulations is that it places responsibility explicitly – and personally – on senior leadership.
| NIS2 requirement | What it means in practice |
|---|---|
| Personal leadership accountability | The board and senior leadership can be held personally liable for breaches |
| Board-level risk assessment | The board approves the risk assessment – not just the CISO |
| Incident reporting | 24 hours: early warning to authorities. 72 hours: full report |
| Supply chain | Requirements extend to sub-suppliers and critical partners |
| Measure documentation | Organisational, physical and technical measures must be documented and maintained |
Many organisations assume NIS2 primarily concerns large actors in critical infrastructure. That is a misconception. NIS2 significantly expands scope compared to the predecessor directive – adding sectors including public administration, waste management and food production. Implementation is underway across the Nordic region, with full enforcement expected in 2026.
→ Do we have an up-to-date overview of which NIS2 requirements apply to our organisation and our supply chain?
→ Has the board approved a risk assessment covering organisational, physical and technical measures?
→ Have we documented the ability to notify authorities within 24 hours of a serious incident?
Three questions the board should ask – and receive concrete answers to
Throughout this article series we have covered four elements: security by design, network architecture, testing and operational response. For a board that wants to take genuine ownership, these three questions are a sound starting point:
1. Do we know which digital assets are most critical – and are confidentiality, integrity and availability secured for them?
2. Have we tested whether we would actually detect an attack – while it was happening?
3. What happens to us if a key supplier or critical partner is compromised?
These questions do not require technical expertise from board members. They require that the CISO or IT director can answer concretely – with documentation, not general reassurances. That is a highly reliable indicator of organisational maturity.
From compliance to competitive advantage
Compliance is the floor – not the ceiling. Organisations that only respond to regulatory requirements are always behind the threat landscape. The strongest use security actively as a strategic asset.
| Compliance mindset | Competitive advantage mindset |
|---|---|
| Responds to requirements – always behind | Acts in advance – always anchored |
| Security is a cost to be minimised | Security is an investment that differentiates |
| Reports to regulators what is required | Documents security posture as a customer argument |
| Supply chain security is someone else’s problem | Sets security requirements in all supplier agreements |
| CISO presents to the board once a year | Board requests security status updates quarterly |
Organisations that document and communicate their security posture to customers, investors and partners find that it differentiates them positively. In sectors such as financial services, healthcare and critical infrastructure, demonstrable security is rapidly becoming a baseline requirement for being considered as a supplier at all.
It is no longer a question of whether the organisation can prioritise security. It is a question of whether it can afford not to.
The foundation of digital trust – in full
This series has covered the four elements that build digital trust. Here they are together:
THE FOUNDATION OF DIGITAL TRUST · NetNordic
1. Security by Design – Security is built in from the start, not patched on afterwards → Articles 1 and 2
2. Network Architecture – Segmentation limits damage and stops lateral movement → Article 3
3. Continuous Testing – Pentest and red team uncover weaknesses before attackers do → Article 4
4. Operational Response – 24/7 monitoring and rapid handling when something does happen → Article 5
All four elements must be in place. That is what separates organisations that preserve trust from those that lose it.
NetNordic helps leadership build and document all four elements – and present the security status to the board in a way that provides genuine insight, not technical jargon.

80+ SOC clients with ~60 NPS score |
2.3 min Average detection time |
#1 Nordics Boss of the SOC 2025 |
Since 2014, NetNordic has handled hundreds of serious security incidents – without any of our SOC customers experiencing a compromised environment under our monitoring. That is not luck. It is the result of rapid detection (2.3 minutes on average), structured incident handling, and combining all four elements of the foundation. Experience with real incidents is also what makes us effective at what matters most: limiting the damage when something does happen.
Trust is built now – or repaired at great cost
Most serious security incidents do not start with advanced hacking techniques. They start with architecture choices, prioritisation decisions and judgements about what is “good enough.”
That means most serious security incidents are preventable. Not necessarily all – but most. And it is leadership’s responsibility to ensure the organisation does what is necessary.
The series “When Security Fails – and Trust Breaks” has shown that digital trust is not a technical problem. It is a leadership question. And the best time to take it seriously is always: now.
