C-suite's role in cybersecurity

If you're a CEO, board member, or senior executive, here's what you need to know: you can now be held personally liable for your company's cybersecurity failures. This isn't a distant possibility. It's today's reality.

Cybersecurity has moved from the IT department to the boardroom. You can no longer treat cybersecurity as someone else's problem. 

This guide will help you understand what you need to know to protect your organization and your career. The changes to the regulatory and business environment now require that you both understand and address cybersecurity risks.

The days of leaving security entirely to your IT team are over, and the stakes have never been higher.

This fundamental change isn't happening by choice. New regulations such as NIS2 and DORA make executives personally liable for security failures. Consider the stakes:

• Cyber attacks cost organizations an average of $3.86 million per incident (IBM, 2025)
• Board members face direct personal liability
• Insurance companies scrutinize your security practices before issuing policies
• Customers increasingly make purchasing decisions based on vendor security ratings

Cybersecurity has become a core business competency, not a technical afterthought.

You don't need to become a cybersecurity expert. You need to understand the language, risks, and strategic implications well enough to make informed decisions and provide effective oversight.

Key cybersecurity terms for executives

Let's start with the vocabulary you need to know. These aren't just technical terms. They're business concepts that directly impact your organization's risk and competitive position.

1. Attack surface = your digital vulnerability footprint

Your attack surface is every digital point where hackers could break into your organization. This includes:

• Every website and web application
• All employee devices (laptops, phones, tablets)
• Cloud services and software
• Third-party vendor connections
  Employee email accounts

The larger your attack surface, the more opportunities hackers have to gain access.
Unlike your physical building with its clearly defined walls and limited doors and windows, your digital attack surface encompasses every device, application, network connection, line of code, user account, and data store.

Each element represents a potential vulnerability — whether you are aware of it or not. Attackers don't just exploit existing entry points. They also create new ones.

What you need to understand

Every website, server, cloud service, employee device, and third-party connection adds to your attack surface. It grows with each new app your team adopts, every remote worker you hire, and every cloud migration you complete.

The most dangerous part? 

Most executives face two critical problems: First, they don’t have an overview of their complete attack surface. Second, they don't realize cyber threats are part of the risks they need to manage. 

Why this matters to your business 

The bigger and messier your attack surface, the higher your chances of getting breached. It's simply because there are more potential entry points for attackers to discover and exploit.

This creates an inherently unfair dynamic. Some businesses naturally have larger attack surfaces than others. For example:

A global financial services firm with hundreds of applications, thousands of employees, and complex third-party integrations will always have a bigger attack surface than a local accounting practice with twenty employees and basic cloud tools.

The goal isn't necessarily to have the smallest attack surface. The goal is to understand what your attack surface includes so you can effectively minimize and manage it. 
Organizations that can't see and manage their digital perimeter face far more security incidents than those with clear visibility and control. This blind spot is exactly what External Attack Surface Management (EASM) platforms are designed to solve.

2. External attack surface management (EASM) = seeing what hackers see

Understanding your attack surface is critical. But first you need to see it. That's where External Attack Surface Management (EASM) comes in.

EASM reveals what hackers see when they examine your organization.

Traditional security tools only monitor what you already know about. EASM tools actively discover assets you didn't know existed — forgotten websites, old test servers still running, or unauthorized cloud apps your teams are using.

Organizations using EASM typically discover 30-40% more vulnerable assets than they knew existed. Each unknown asset could be your next breach point.

What you need to know

EASM platforms automatically discover digital assets you don't know exist:

• Forgotten subdomains and development environments
• Shadow IT applications adopted without approval
• Third-party services with lingering access to your systems

The critical gap most EASM tools miss: employee credential exposure

This last category represents the most common blind spot in traditional security approaches.

Example: An employee uses their work email to sign up for a shopping site. That site gets hacked. Now attackers have a real company email address to target with phishing attacks. And what if employees are using the same breached password for company accounts? 

Most security platforms focus exclusively on corporate infrastructure—servers, domains, and applications—while overlooking the human dimension of your attack surface.

You can't make informed risk decisions about assets you're unaware of. 

Modern EASM platforms provide continuous monitoring and turn complex technical vulnerabilities into actionable business insights. And the best ones include an employee risk score and password breach detection. 

3. Security score = your cybersecurity report card

Security metrics provide a picture that represents your organization's cybersecurity health and security resilience. It also reveals how attractive you are as a target in the eyes of an attacker.

It measures how vulnerable you appear to hackers.

Your security score works like a credit score, but for cybersecurity. Just as lenders check your credit score before approving a loan, customers and partners now check your security score before doing business with you.

The score (typically 0-100) measures your visible vulnerabilities:

• Unpatched software
• Misconfigured systems
• Exposed sensitive data
• Weak security practices

A low score doesn't just indicate risk. It’s also costing you business.

What you need to know 

Security metrics should be included in your standard business KPI dashboard and deserve the same executive attention because they directly impact all of your traditional business metrics.

Moreover, these metrics aren't just for internal use. Customers, partners, and insurers increasingly check security ratings before making business decisions.

The business impact

A security breach doesn't just affect your IT department. It disrupts revenue, destroys customer trust, and derails strategic initiatives. 

More importantly, security scores provide the quantifiable metrics that boards and investors expect when evaluating cybersecurity ROI. Organizations achieving scores above 95/100 demonstrate the kind of security excellence that becomes a competitive differentiator.

Modern security scores make cybersecurity tangible and measurable for entire organizations, from the CEO to individual employees. This quantified approach transforms cybersecurity from an abstract concern into a concrete business metric that drives organizational behavior and accountability.

Critical threats every executive must recognize

Now that you understand the key terms, let's look at the specific threats targeting your organization right now.

Understanding terminology gives you the vocabulary for informed decision-making. But knowledge alone isn't enough. You need to recognize the specific threats targeting your organization and the defenses available to counter them.

Phishing 

Deceptive messages are designed to trick employees into clicking malicious links, downloading infected files, or providing sensitive information. 

Phishing attacks have become increasingly sophisticated. They often come from trusted sources like vendors, partners, or colleagues. 

Since over 80% of successful cyber attacks involve human interaction, phishing represents one of your highest-priority security concerns.

Ransomware

Malicious software that encrypts your organization's data and demands payment for the decryption key. Modern ransomware attacks often include data theft and the threat of publishing sensitive information if ransom demands aren't met. 

Ransomware can cripple operations for weeks or months, making it one of the most disruptive cyber threats facing businesses today.

Zero-day attacks

A security flaw in software that is unknown to the vendor. The vulnerability exists in the code but hasn't been discovered or disclosed yet. The name refers to developers having zero days to fix the problem because they are unaware of its existence.

Zero-day vulnerabilities can remain undiscovered for months or even years before they are identified. When attackers find these flaws first, they can exploit them with no available defense or patch. These exploits are particularly valuable and are often sold on underground markets or reserved for high-value targets by sophisticated threat actors.

The good news? 

Zero-days represent a tiny fraction of successful breaches. Most attacks exploit known vulnerabilities that organizations have not yet patched.

Regulatory landscape: NIS2, DORA, and personal executive liability

Regulations create the legal framework. Understanding them drives home why this matters to you personally.

Cybersecurity compliance is no longer just a checkbox exercise. Today, it's a source of direct personal liability for executives.

Beyond good governance, understanding this landscape is also career preservation. Two major regulations now make executives personally accountable:

NIS2 directive: the new standard for European cybersecurity

The Network and Information Security Directive 2 (NIS2) represents the European Union's most comprehensive approach to cybersecurity resilience across critical sectors and essential entities.

Who does it affect? 

NIS2 casts a much wider net than its predecessor. It covers:

• Essential entities (energy, transport, banking, healthcare)
• Important entities (postal services, waste management, manufacturing, digital providers)
• Organizations with 50+ employees or €10 million+ annual turnover

Executive liability 

Here's where NIS2 breaks new ground. Management bodies of essential entities bear direct responsibility for cybersecurity risk management measures. Directors can face personal sanctions, including potential disqualification from management positions.

Key requirements

Organizations must:

• Implement appropriate technical and organizational measures
• Report significant incidents within 24 hours
• Demonstrate that cybersecurity is integrated into overall risk management frameworks

Consequences 

• Fines up to €10 million or 2% of total worldwide annual turnover, whichever is higher
• Personal sanctions for executives can include temporary prohibition from exercising management functions

DORA: financial sector digital resilience

The Digital Operational Resilience Act (DORA) specifically targets financial entities, creating stringent requirements for digital operational resilience.

Who does it affect?

All EU financial entities:

• Banks
• Insurance companies
• Investment firms
• Crypto-asset service providers
• Their critical third-party ICT service providers

Executive liability

DORA places explicit responsibility on management bodies to approve and regularly review digital operational resilience strategies. Personal accountability extends to ensuring adequate resources and maintaining appropriate oversight.

Key requirements

• Comprehensive ICT risk management
• Incident reporting within 2-4 hours for major incidents
• Digital operational resilience testing (including advanced penetration testing)
• Third-party risk management

Consequences

Member states can impose administrative sanctions, including temporarily prohibiting senior management from exercising management functions in financial entities.

Personal liability = your career is on the line

The regulatory shift has completely rewritten the rules of executive accountability. For decades, corporate executives relied on the legal principle that the corporation, not individual leaders, bore responsibility for most business failures.

Cybersecurity has shattered that protection.

Executives now face personal fines and legal consequences. Ignorance of cybersecurity risks is no longer a viable defense strategy. Regulators and prosecutors increasingly view cybersecurity failures as management failures with personal consequences to match.

You could face both personal fines and corporate penalties.

Board member due diligence has also taken on new meaning in this environment. Passive oversight is no longer sufficient when personal liability is on the table. This means:

• Asking informed questions during board meetings.
• Understanding the risk reports your security teams provide.
• Allocating adequate resources for cybersecurity programs. 

Career consequences extend far beyond regulatory penalties. Post-breach, executives often face career-ending consequences. Even if you avoid regulatory sanctions, the marketplace usually delivers its judgment on cybersecurity leadership failures.

The insurance landscape compounds these personal risks.

While cyber insurance policies now offer personal liability coverage for executives, this protection comes with strings attached.

Insurers require clear evidence that you understood cybersecurity risks and took reasonable steps to address them. Without that documentation, you could face regulatory penalties and personal financial exposure with no insurance safety net.

The $3.86 million reality: average cost of cyberattacks in 2025 (IBM report) 

The financial impact drives home why cybersecurity leadership matters.

According to IBM's 2025 Cost of a Data Breach Report, the average data breach cost reached $3.86 million globally. Yet this stark reality becomes even more concerning when examined through real business impact scenarios.

Understanding the full cost spectrum

Beyond the headline $3.86 million figure lies a more complex picture of organizational damage.

Consider a practical example: if 100 employees earning $40 per hour remain idle for 8 hours during a system outage, your organization loses $32,000 in productivity alone. And that's before counting the broader operational impacts.

Immediate operational costs include:

• Complete revenue loss for e-commerce operations during downtime
• Manufacturing and logistics disruption
• Emergency staffing and overtime costs for incident response
• Third-party cybersecurity firm engagement (often tens of thousands of dollars)

Regulatory and compliance costs are escalating:

• GDPR fines can reach €20 million or 4% of global annual turnover, whichever is higher
• New regulations like NIS2 and DORA create direct executive liability
• Ongoing compliance monitoring and reporting requirements

Long-term business impact often exceeds immediate costs:

• Customer churn and acquisition costs to rebuild trust
• Brand reputation recovery requires extensive marketing investment
• Increased cyber insurance premiums are affecting annual budgets
• Potential ransom payments (though not recommended by authorities)

The "cost of doing nothing" calculation

Rather than focusing solely on traditional ROI metrics, modern executives must evaluate cybersecurity through what leading practitioners call the "cost of doing nothing" framework.

This approach views cybersecurity investment as a form of business insurance against catastrophic loss.

The stark reality: 90% of security breaches are preventable through proper planning and investment, yet 60% of companies will experience cyber attacks within the next two years.

This means organizations have a narrow window to implement protective measures before joining the ranks of breach victims.

Understanding the skills gap and why leadership involvement is critical

The global cybersecurity workforce shortage represents a strategic business risk that hiring alone cannot solve. You must understand the scope of this challenge and why executive involvement becomes a force multiplier for organizational security.

The crisis in numbers

Over 80% of data breaches involve human interaction, yet organizations struggle to build adequate security awareness and capabilities across their workforce.

The skills gap extends beyond technical expertise. It includes strategic thinking, business risk assessment, and cross-functional security integration.

Why can't technical teams solve this alone? 

Most cybersecurity professionals excel at technical implementation but require executive support for resource allocation, cultural change management, and strategic decision-making.

Security teams understand what needs to be done. They need leadership authority to implement business-wide security initiatives that span departments and require organizational change.

Organizations with engaged executive leadership report significantly higher employee compliance with security policies and more effective security partnerships.

Executive involvement in cybersecurity creates measurable organizational improvements:

• Better resource optimization
• More substantial cultural transformation around security awareness
• Improved strategic alignment of security investments
• More effective vendor partnerships that serve business needs rather than just technical requirements

When you understand both cybersecurity terminology and its business impact, you can make informed trade-off decisions and ensure that security investments align with business objectives.

The shift from "IT responsibility" to "business responsibility"

Modern cybersecurity is recognizing that security is a business risk that requires business leadership.

The traditional model

Under the old model, IT departments owned all cybersecurity decisions:

• Security was viewed as a technical implementation challenge
• Business leaders expected IT to "handle" security without deeper involvement
• Security investments were judged purely on technical merit
• Incident response was considered an IT operational issue

This model was effective when organizations had clear digital boundaries and limited external dependencies. It fails catastrophically in today's interconnected, cloud-first, remote-work business environment.

The new reality

Modern cybersecurity requires business leadership because:

• Risk decisions are business decisions. Choosing what to protect, how much to spend, and what risks to accept requires understanding business priorities and trade-offs only business leaders can make.
• The impact on customers is immediate. Security incidents directly affect customer experience, trust, and revenue, requiring business leadership and communication expertise.
• Regulatory compliance is an executive responsibility. New regulations explicitly place cybersecurity accountability at the executive level, making it a governance and leadership issue.
• Competitive differentiation. Strong cybersecurity becomes a market advantage requiring strategic positioning and business development, not just technical implementation.

Four mindset shifts leaders must internalize

Your first shift: stop thinking of security as a cost center. 

Security investments create business value through risk reduction, regulatory compliance, customer trust, and market differentiation. When you frame security properly, it becomes a competitive advantage rather than a necessary evil.

Your second shift: Accept that perfect security doesn't exist. 

The goal isn't preventing every attack. It's building organizational capability to detect, respond to, and recover from inevitable incidents. Organizations that survive and thrive after security incidents are those that plan for resilience, not those that believe they are invulnerable.

Your third shift: measure security success in business terms. 

Customer impact, revenue protection, and operational continuity matter more than technical metrics. Your board and investors care about business outcomes, not vulnerability counts or patch compliance percentages.

Your fourth shift: understand who you're protecting. 

The primary "customer" of cybersecurity isn't your internal business users. It's your organization's actual customers whose data and trust you're protecting. This perspective alters how you approach security investments and trade-offs.

These mindset shifts require concrete changes in how you operate as a leader. 

You need regular briefings on security posture, threat landscape, and incident status that you can understand and act upon. Security resource decisions should involve business leaders who understand strategic priorities and can make informed trade-offs between security and other business needs.

You must also integrate security considerations into core business processes: 

• Product development
• Customer onboarding
• Vendor management
• Strategic planning

Security can't be an afterthought bolted onto business decisions. It needs to be part of the decision-making process from the beginning.

Finally, you must be prepared to communicate about security incidents, improvements, and investments to customers, partners, investors, and regulators.

Security communication is a CEO-level responsibility that cannot be entirely delegated to your technical teams.

Key takeaways

Your organization's security posture now directly impacts your career, your legal liability, and your company's survival. Understanding the concepts in this chapter isn't optional professional development—it's career insurance.

Before moving forward, assess: 

• Can you explain your organization's attack surface to your board? 
• Do you know your current security status? 
• Can you articulate which regulations create personal liability for you?

If not, those become your first action items. 

The era of delegating cybersecurity responsibility is over. Your next security decision could define your career. Make sure you're equipped to make it wisely.
