Building a Cyber Security Strategy for NIS2 and Growth

Compliance pressure can make cyber security feel like a defensive exercise. For CEOs, COOs, CROs, HR leaders and talent teams in fast-growing companies, that is too narrow. A strong cyber security strategy should help the organisation win enterprise customers, integrate acquisitions, protect revenue platforms, pass procurement reviews and scale across borders without creating avoidable risk.

NIS2 raises the stakes because it moves cyber resilience into the leadership agenda. It affects governance, accountability, suppliers, incident reporting and the skills needed inside the business. The companies that treat it as a one-off compliance project will usually end up with policies that look neat but fail under operational pressure. The companies that connect NIS2 to growth will build a security model that customers, investors and regulators can trust.

Why NIS2 has become a growth issue

The EU NIS2 Directive expands cybersecurity obligations across more sectors and places greater emphasis on risk management, supply chain resilience, incident handling and management accountability. Exact requirements depend on national implementation, so legal advice remains important, especially for organisations operating across several EU jurisdictions.

For leadership teams, the practical question is bigger than whether the business is in scope. NIS2 is part of a wider market shift. Enterprise buyers are asking tougher questions about security controls. Boards want clearer evidence of resilience. Insurers, investors and procurement teams increasingly expect documented governance, incident readiness and supplier oversight.

That is why a cyber security strategy should be built around business continuity and trust. If your revenue depends on SaaS platforms, customer data, industrial systems, regulated partnerships or cross-border delivery, weak cyber governance can slow sales and constrain expansion. Strong governance can do the opposite by shortening security reviews, improving customer confidence and reducing disruption.

Start with the business model, not the control catalogue

Many companies begin by asking which controls they need. A better starting point is how the business creates value and where disruption would hurt most. A strategy for a cloud platform company will not look the same as one for digital health, smart manufacturing or AI infrastructure. The threat profile, customer expectations and operational dependencies differ.

Leadership should begin with a clear map of the assets, services and relationships that matter to growth. That includes customer-facing platforms, identity systems, data environments, critical suppliers, support operations, finance systems and the people who can change or approve sensitive activity.

A useful executive conversation covers five questions:

• Which products, services or processes would cause material damage if unavailable for 24, 48 or 72 hours?
• Which data sets carry the highest regulatory, contractual or reputational risk?
• Which suppliers, cloud services and managed providers are essential to delivery?
• Which markets or customer segments impose the toughest cyber assurance expectations?
• Which executive owns the trade-off between speed, cost, resilience and acceptable risk?

This framing keeps the strategy commercial. It also prevents the common mistake of building an impressive security programme around systems that are not the biggest source of risk.

Build governance that your operating model can sustain

NIS2 makes governance harder to delegate informally. Leadership teams need a clear model for who decides, who implements, who monitors and who reports. In a scale-up, this may involve a founder, COO, CTO and fractional CISO. In a larger organisation, it may require a CISO, GRC lead, security engineering team, legal counsel, procurement leadership, HR and regional business owners.

The important point is authority. A cyber leader without budget influence, access to the board or power to challenge risky decisions is unlikely to deliver meaningful resilience. Equally, a board that receives technical updates without business impact will struggle to make sound decisions.

A practical governance model should define:

• Board or executive oversight of cyber risk, including reporting cadence and decision rights
• Named ownership for NIS2 readiness, risk treatment and evidence gathering
• Clear escalation routes for incidents, supplier failures and control exceptions
• Accountability for security in product, sales, procurement, HR and IT operations
• A talent plan that separates permanent leadership needs from specialist external support

If you are deciding which roles to prioritise, Optima has covered the sequencing in its guide to NIS2 hiring priorities for European leadership teams. The central lesson is that hiring should follow the operating model, not the other way round.

Translate NIS2 into a practical security programme

A strong cyber security strategy turns regulatory expectations into workstreams that leaders can fund, measure and improve. The detail will vary by sector and country, but most NIS2-ready programmes include the following building blocks.

Scope and criticality

Define which entities, geographies, services and systems are in scope. Then identify critical business services and supporting assets. This should include cloud environments, identity infrastructure, operational technology where relevant, third-party platforms and key data flows.

The output should not be a static asset inventory that disappears into IT. It should inform investment choices, business continuity planning and incident prioritisation. When everything is critical, nothing is.

Risk management and controls

NIS2 expects appropriate technical, operational and organisational measures. In practice, that means controls such as access management, multi-factor authentication, vulnerability management, secure configuration, backup resilience, logging, endpoint protection, secure development and employee cyber hygiene.

The strategy should set risk-based priorities. For example, privileged access, identity compromise and unpatched internet-facing systems are often more urgent than lower-impact policy refinements. The board does not need to debate every technical control, but it does need visibility on the risk accepted when remediation is delayed.

Incident response and reporting

NIS2 includes stricter incident reporting expectations, including early warning and follow-up notification timelines for significant incidents where applicable under national rules. That means companies need more than a document labelled incident response plan.

They need rehearsed decision pathways. Who confirms severity? Who contacts regulators or national authorities? Who speaks to customers? Who preserves evidence? Who decides whether to isolate systems, pause services or activate disaster recovery?

Tabletop exercises are especially useful because they expose gaps before a real incident. In many firms, the weakness is not technical detection. It is unclear executive ownership under time pressure.

Supplier and ecosystem resilience

Growth companies often rely on a complex ecosystem of SaaS tools, cloud providers, outsourced IT, delivery partners and specialist vendors. NIS2 increases the importance of supply chain security, but the commercial reason is simple: a supplier outage or breach can become your customer problem.

Supplier governance should segment vendors by criticality, not by contract size alone. A relatively inexpensive platform can still be business-critical if it handles identity, customer data, payments or production workflows. Procurement, legal, IT and security teams need a shared process for onboarding, monitoring and renewing high-risk suppliers.

Evidence and assurance

Policies matter, but evidence proves the operating model works. That evidence may include risk registers, control testing, supplier assessments, training records, incident exercise outputs, vulnerability remediation logs, backup test results and executive minutes.

Good evidence also supports sales. When enterprise customers ask about security maturity, a company with organised assurance materials can respond faster and with more credibility.

Make cyber security a commercial advantage

A growth-oriented cyber security strategy helps revenue teams as well as risk teams. CROs and sales leaders should care because customer security reviews can slow or block enterprise deals. Product leaders should care because security requirements influence roadmap decisions. HR leaders should care because employees, contractors and executives are part of the threat surface.

Security also supports market entry. If a company is expanding from Europe into North America, or managing distributed operations across the US and Europe, it needs consistent governance with local execution. A Southern California subsidiary, for example, may combine central risk ownership with regional providers such as VM Tech's managed IT services for cybersecurity-first IT support, cloud operations, backup and day-to-day technology resilience.

The same principle applies globally. The board sets risk appetite and operating standards. Regional teams and trusted partners adapt execution to local infrastructure, customer requirements and response needs.

Decide what to hire, outsource and upskill

Cyber security talent is expensive because the best people combine technical judgement, regulatory awareness and commercial maturity. Hiring every capability internally is rarely realistic, especially for high-growth companies. The aim is to own the roles that create accountability and outsource activities where specialist scale, 24-hour coverage or deep technical tooling is more efficient.

A common model is to keep cyber leadership, governance, risk ownership and business-facing security strategy close to the company. Specialist areas such as managed detection, penetration testing, forensic support or certain cloud security projects may be better delivered through external partners, provided internal ownership remains clear.

The first senior hire should usually be someone who can translate between the board, technology teams and commercial stakeholders. Titles vary: CISO, Head of Security, VP Security, Director of GRC or Security Programme Lead. What matters is the mandate. They must be able to influence priorities, budgets and behaviour across the business.

NIST Cybersecurity Framework can help leaders define capabilities in plain language. It is not a replacement for NIS2, but it gives a useful structure for discussing govern, identify, protect, detect, respond and recover. Optima’s guide to NIST CSF for European hiring leaders explains how to use the framework as a talent planning tool rather than a purely technical checklist.

A 90-day roadmap for leadership teams

A full cyber security strategy may take longer than 90 days to mature, but leadership can create momentum quickly if the work is sequenced properly.

Days 1 to 30: Establish the baseline

Start with scope, ownership and risk visibility. Confirm whether entities and services may fall under NIS2 or equivalent obligations. Identify critical business services, key systems, high-risk suppliers and existing security documentation. Create a concise executive risk register that separates urgent operational risk from longer-term maturity gaps.

This first month should also clarify governance. Name the accountable executive sponsor, decide reporting cadence and agree how cyber risk will be presented to the board or executive committee.

Days 31 to 60: Prioritise controls and response readiness

Use the baseline to prioritise control improvements. Identity and access management, multi-factor authentication, backup resilience, vulnerability remediation and logging often produce early risk reduction. At the same time, build or refresh the incident response model.

Do not wait for perfect tooling before testing escalation routes. A short tabletop exercise with leadership, IT, legal, communications, HR and customer-facing teams can reveal whether people understand their role in a significant incident.

Days 61 to 90: Build the investment and talent plan

Convert the first two months of learning into a 12 to 18 month roadmap. This should include control milestones, supplier assurance activity, hiring needs, outsourced support, training, budget and reporting metrics.

By day 90, the leadership team should be able to explain the strategy in business language: what risks are being reduced, what capabilities are being built, what investment is required and how progress will be evidenced.

Metrics that matter to the board

Cyber metrics can become too technical for executive use. The board needs measures that show whether risk is being managed and whether the organisation is becoming more resilient.

Useful executive metrics include the percentage of critical assets covered by key controls, time to remediate high-risk vulnerabilities, privileged access review completion, backup restore test success, incident exercise outcomes, high-risk supplier assessment coverage and open risk exceptions by business owner.

Commercial metrics also matter. Track how often security evidence supports customer procurement, how many enterprise deal reviews are delayed by missing controls and which customer requirements appear repeatedly. This helps connect cyber investment to revenue enablement instead of treating it only as cost avoidance.

Common mistakes to avoid

The first mistake is treating NIS2 as a legal project. Legal interpretation is necessary, but resilience is operational. If IT, security, procurement, HR, product and revenue teams are not involved, the strategy will not survive contact with the business.

The second mistake is hiring before defining the mandate. A strong candidate cannot compensate for unclear authority, fragmented ownership or an unwillingness to fund remediation. Define the operating model first, then recruit into it.

The third mistake is confusing documentation with readiness. Policies may satisfy an initial review, but incidents test behaviour. Evidence, exercises and measurable control performance matter more than polished documents.

The fourth mistake is ignoring suppliers until renewal. High-risk vendors should be assessed before onboarding, monitored during the relationship and reviewed when the business changes how it uses them.

Frequently Asked Questions

What is a cyber security strategy? A cyber security strategy is a leadership plan for managing cyber risk across people, processes, technology, suppliers and governance. It should connect security priorities to business objectives, regulatory obligations, customer trust and operational resilience.

How does NIS2 affect executive teams? NIS2 increases the importance of management accountability, risk management, incident reporting and supplier security. For executive teams, it means cyber security can no longer sit only within IT. It requires board-level oversight and cross-functional execution.

Is NIS2 only relevant to companies based in the EU? Not always. Non-EU companies can be affected if they provide services into EU markets, operate EU entities or serve customers that require NIS2-aligned assurance. The exact position depends on sector, structure and national implementation.

Should we use NIST CSF, ISO 27001 or another framework? Many organisations use recognised frameworks to structure controls and evidence. NIST CSF is useful for leadership communication, while ISO 27001 can support formal management system certification. The right choice depends on customer expectations, regulatory scope and maturity.

Which cyber security roles should we hire first? Start with the role that creates accountability and translates cyber risk into business decisions. This may be a CISO, Head of Security, GRC leader or senior security programme owner. Specialist engineering and operations roles should follow the strategy and risk profile.
