Why an AI-Phishing Benchmark is Critical for Your 2025 Strategy
Discover the ranking of the most vulnerable sectors to AI-phishing in 2025. Learn key countermeasures to comply with NIS2 and protect your organization.

Why an AI-Phishing Benchmark is Critical for Your 2025 Strategy
Taking a proactive stance against AI-phishing is not just best practice, it’s a strategic and regulatory necessity. A sector-specific benchmark gives you the risk map you need to navigate this new environment, allowing you to move from generic defense to a precise, justified 2025 cybersecurity strategy.
The Qualitative Impact of AI-Phishing: Beyond Metrics
The true danger of AI-driven phishing is not its volume, but its quality. This technology disables the “instinct” your employees relied on to detect fraud. AI generates hyper-realistic lures, with perfect context and tone, and without the telltale mistakes of the past.
Imagine an email referencing last week’s conversation or a confidential internal project. AI doesn’t just automate phishing; it makes it virtually indistinguishable from reality, turning even your most cautious employees into potential victims.
According to IBM’s latest Cost of a Data Breach Report, the global average cost of an incident already exceeds €4 million—clear evidence of the need to anticipate increasingly sophisticated attacks.
NIS2 and the Requirement for Risk-Based Cybersecurity
The NIS2 Directive imposes a structural change: it requires senior management to oversee and approve cybersecurity measures based on ongoing, demonstrable risk assessment. It’s no longer enough to “do security”; now you must prove your actions are appropriate and effective.
Here’s where an AI-phishing benchmark 2025 becomes your best ally. It allows you to:
- Justify investments: Use benchmark 2025 data to show your board that investing in human risk management is a top priority, grounded in sector-specific evidence.
- Demonstrate due diligence: Prove to regulators that you’ve conducted a specific risk assessment and are implementing proportionate countermeasures.
Risk-based cybersecurity is not optional—it is the core requirement of NIS2 compliance. For further details, refer to ENISA’s official NIS2 Directive resources.
Ranking 2025: The 4 Most Vulnerable Sectors to AI-Phishing
While all organizations are targets, sectoral vulnerability is uneven. Our 2025 AI-phishing benchmark identifies four areas where risk is exponentially higher—based on data value, operational criticality, and regulatory pressure.
- Financial & Insurance (Banking, Fintech)
The financial sector remains the prime target for a simple reason: direct access to capital. AI enables attackers to bypass traditional defenses and carry out spear-phishing attacks at massive scale. Imagine hundreds of personalized emails sent to account managers or executives, each with the perfect context to authorize a fraudulent transfer. Here, the goal is direct access to funds—and AI makes it scalable. - Healthcare (Hospitals, Pharmaceuticals)
The sensitivity and value of personal health information (PHI) make this sector a top target for ransomware and extortion. High-pressure environments and operational urgency create ideal conditions for social engineering. Overloaded staff plus extremely valuable black-market data equals maximum risk for AI-phishing. An urgent, AI-generated email about a patient could be the perfect bait. - Critical Infrastructure (Energy, Water, Transportation)
In this case, attacks often go beyond financial motives and focus on operational disruption. A successful AI-phishing attempt against an engineer or operations lead could be the entry point for compromising Operational Technology (OT) systems. The risk extends far beyond data loss—to the potential paralysis of essential services. - Public Administration & Defense
With massive attack surfaces and strategically invaluable data, public administration is a high-profile target. Attackers can use AI to impersonate senior officials and gain access to classified information. Yet the greatest challenge is internal: engaging civil servants in cybersecurity is the primary protective factor for national security. Fostering a culture of constant vigilance here is as crucial as it is complex.

Essential Countermeasures and Strategic Recommendations
Identifying risks via an AI-phishing benchmark is only the first step. The next—and most critical—is to act. Strong defense rests on three interconnected pillars: technology, processes, and people.
Technology: AI-Augmented Email Defenses
Traditional Secure Email Gateways (SEGs) are no longer sufficient. They block known threats, but AI-phishing is a zero-day social engineering attack. Your first defense layer must be as smart as the attack itself. You need AI-powered solutions that:
- Analyze message context and intent, not just signatures or reputation.
- Perform dynamic sandboxing of links and attachments before reaching the user.
- Run real-time URL analysis to block newly created malicious domains.
Processes: Strengthen Your Incident Response Chain
Technology will detect many attacks, but some will reach employees. The goal is for employees to act as effective threat sensors. That means frictionless, safe reporting channels—with no fear of repercussions. Swift reporting integrated into your SOC workflows is key to rapid containment.
People: Security Culture and Human Risk Measurement
This is the heart of your defense. Forget annual theory-based training. Cybersecurity culture isn’t imposed—it’s built through continuous awareness and real behavior measurement.
- Run ongoing phishing simulations, including AI-driven scenarios.
- Tailor attacks by role, department, and risk level.
- Measure real behavior (report rate vs. click rate), not just theoretical knowledge.
Frameworks like MITRE ATT&CK® emphasize “Initial Access” as an industry standard tactic—these human-centered defenses directly strengthen resilience against it.
Drive a Continuous Awareness Program Aligned with NIS2
To defend against AI-phishing—a critical threat highlighted in this 2025 benchmark—and comply with NIS2, awareness must evolve. Abandon one-off events in favor of measurable, continuous resilience.
From One-Off Training to Measurable Security Culture
An annual course won’t cut it. NIS2 requires a cyclical, continuous improvement process. Adopt a strategic cycle:
- Assess: Identify initial risk level.
- Train: Deliver contextual knowledge.
- Simulate: Measure behavior with realistic attacks.
- Measure: Analyze results, adjust, and restart.
Measure What Matters: Behavior, Not Just Clicks
Click rates only measure failure. True security maturity is reflected in behavior—particularly reporting rates. The key KPIs for CISOs to present are:
- Phishing report rate
- Average detection time by employees
- Resilience index
This human risk management model not only fulfills NIS2, but also aligns with ISO/IEC 27001 global standards for Information Security Management Systems.
Frequently Asked Questions
Which sectors are most affected by AI-phishing in 2025?
Banking & Insurance, Healthcare, Critical Infrastructure, and Public Administration—due to high-value data, operational criticality, and strong regulatory pressure under NIS2.
How does a cybersecurity benchmark help with NIS2 compliance?
It enables identification and prioritization of sector-specific risks, a core requirement of the NIS2 Directive. It’s essential for justifying investments and demonstrating proactive, risk-based cybersecurity management to regulators.
Is technology alone enough to stop AI-phishing?
No. Technology is essential but must be complemented by well-defined response processes and, crucially, a strong security culture—treating human risk as the ultimate adaptive defense.
What’s the first step in creating a defense against AI-phishing?
Start with an initial assessment to measure employee resilience. A controlled phishing simulation provides the objective baseline needed to build and adapt a continuous awareness strategy.
