When a major cyber incident hits, all eyes are on the CISO.

They become the invisible CEO of crisis, steering the entire enterprise through the storm, managing stakeholders and making major decisions under immense pressure. The clock is ticking. Every minute can mean more systems affected, more data exposed, greater operational disruption and a growing risk to customer trust and corporate reputation.

And this on top of an already expanded day-to-day role, where they are expected to make decisions with incomplete information, brief the board, support legal and communications teams, manage technical response and reassure the business, all while knowing that any delay could increase the damage.

But a troubling pattern often emerges once the smoke clears. The CISO may find themselves held responsible for the incident that just happened, and in some cases personally liable, while still being expected to prevent the next one. Yet, at the same time, their influence over the strategic decisions that shape cyber risk can quickly diminish. 

This cycle takes a toll. Across EMEA, we are seeing the personal and organisational impact of that pressure, from burnout and leadership turnover to growing concerns about long-term resilience.

That pressure often comes at a demanding stage of life too. Many security leaders reach the CISO role when career responsibility is peaking at the same time as responsibilities outside work, from ageing parents and family commitments to their own health.

With an average CISO tenure now reduced to between 18 and 26 months, and nine out ten reporting feeling moderate to high stress, a more sustainable model is needed for structural and personal resilience.

Cybersecurity is far more complex than it was a decade ago. AI-powered attacks and autonomous agents are increasing the speed and scale of threats. At the same time, the CISO has never had more potential influence over business strategy. The challenge is ensuring the support around the role evolves as quickly as the threat landscape.

That is why it’s time to stop treating cybersecurity as a technical function alone and recognise the CISO as a strategic business leader.

Structural equity - breaking the cycle of isolation

The burden of cyber resilience should not rest on one individual. Yet too often, organisations place responsibility on the CISO without providing the support, influence or measures of success needed to help them thrive.

Part of the problem is how the role is measured. CISOs are judged by whether incidents happen, rather than by the quality of preparation, resilience planning, risk reduction and secure business enablement.

And preparation can really help reduce the pressure. Regular red teaming, tabletop exercises and incident simulations mean the CISO is not carrying the crisis alone when a breach happens. The organisation has rehearsed its roles, decision points and escalation paths before the stakes are at their highest. 

But after a crisis, organisations also often fall back into day-to-day survival mode, undoing the progress made when security was treated as a critical part of business planning rather than a technical function. Strong resilience requires the CISO to have a permanent seat at the table for all strategic decisions, from M&A to digital transformation.

That influence only comes with strong foundations. This includes visibility of critical assets and risks, security controls that are fit for purpose and the operational discipline to maintain them over time.

• Invest in leadership as much as certifications: The modern CISO needs diplomacy, judgement and the ability to translate risk into business terms. Different backgrounds can strengthen that role, bringing fresh perspective when solving problems that are no longer purely technical
• The ‘Shared CISO’ model: Cyber resilience should not rest on one pair of shoulders. The most resilient organisations embed responsibility for cybersecurity across the business, while creating stronger support structures around the CISO through deputies, shared ownership of cyber risk and clear succession planning. This reduces pressure on individual leaders and helps ensure resilience is built into the organisation itself

Strategic diplomacy - aligning people and purpose

Cyber resilience depends on people as much as technology, and a CISO’s success depends on building alliances across the business. The strategic diplomat CISO focuses on moving the conversation from ‘no’ to ‘how?’ by building deep relationships with other leaders, every team and every department across the organisation.

By understanding the business’ growth drivers, the CISO can align security goals with the board’s priorities. That means agreeing meaningful measures of risk and readiness, preparing for difficult questions and giving the business a clear view of where it is exposed. 

Security and growth must be seen as a single strategic fabric. Integrating security into the development of internal AI tools and customer-facing products helps ensure innovation is secure by design, rather than being a hurdle to overcome later.

The Future of Threat Defense Resides at the IP Layer

For years, network security operated on a relatively predictable premise: inspect traffic, identify malicious content, and block it. Because deep content inspection created a seemingly robust defense in depth, relatively static legacy approaches—like reliance on threat intelligence feeds—were allowed to simply persist in the background.

The weaponization of agentic AI and highly evasive techniques has fundamentally shattered that model. Attackers are no longer just iterating on old threats. They are launching attacks at staggering velocity, completely outpacing threat feeds, and employing evasion tactics that actively starve legacy prevention solutions of the content they rely on to inspect.

Our new research report from Unit 42, Attackers Are Evading Threat Prevention at the Internet Edge, reveals how adversaries are actively exploiting the contextual vacuum at the IP layer to bypass standard security controls. For security leaders, understanding this shift is no longer optional. As the nature of the threat fundamentally changes, our strategic approach to network security must definitively change with it.

The AI-Accelerated, Evasive Attack Lifecycle

To understand why legacy defenses are failing, we must look at how adversaries are accelerating and obfuscating every stage of the attack lifecycle. As these threats progress, the commonly used network indicators we have long relied upon are vanishing, collapsing traditional defenses and leaving defenders with little to act on.

Powered by frontier AI, adversaries now automate reconnaissance and exploitation at huge scale and speed, while using anonymizers to mask their intent. Once an intrusion is launched, orchestration shifts to highly evasive command and control (C2). Attackers hide communications using advanced encryption and AI-built malware-less techniques. They’re also bypassing traditional web and DNS inspection entirely by routing traffic directly to IP addresses—a tactic Unit 42 found in 23% of modern malware

Ultimately, the takeaway is clear: network threat prevention can no longer rely solely on detecting malicious payloads. As AI-driven attacks continue to minimize their footprint, security strategies must augment content inspection with real-time IP layer monitoring to left-shift threat detection and counter these rapid, machine-speed threats at the network foundation.

Existing Approaches Aren’t Working

Where content-based detection falls short, many security vendors and organizations still rely on IP threat intelligence feeds to pick up the slack in an attempt to filter out malicious connections on the network layer. However, after years of operating under this model, the results are in—the traditional feed is showing its age.

Attackers have long relied on proxies, anonymizers, residential routers and public cloud providers as a tactic to evade detection. However, agentic AI morphs this process, enabling rapid infrastructure rotation and stealth at an unprecedented scale. As this autonomous evasion accelerates, experienced network defenders continue to run into the well-known limitations of classic IP blocklists:

• Too slow to keep pace: Unit 42 found an average 20-day lag time before new threats hit popular feeds. Because agentic AI enables adversaries to autonomously rotate proxy IPs in hours, these lists are obsolete at the moment of delivery.
• Fundamentally incomplete: IP feeds are unable to see a massive portion of the modern attack surface. Unit 42 research indicates that 52% of malicious IPs used for direct-to-IP connections are completely absent from these lists.
• Unactionable on shared infrastructure: Even known threats are often impossible to block. The Unit 42 team reports that 37% of direct-to-IP traffic uses reputable CDNs and cloud providers. IP feeds cannot distinguish malicious connections from legitimate ones, making blocking too risky for business continuity.
• A management nightmare: Among the security teams that Unit 42 polled, 30% indicate resource-intensive vetting and false-positive triage as their top pain point. To avoid breaking legitimate traffic, feeds are frequently relegated to an alert-only mode, defeating the entire purpose of prevention.

If modern and agentic AI-enabled attacks can outrun traditional network payload-based detections, we need a new weapon in the network defender’s arsenal. We can no longer depend on yesterday’s IP feeds to secure such an extremely agile threat environment.

The Blueprint for Modernizing the Internet Edge

To outpace the impact of agentic AI and advanced evasion on network threat prevention, security leaders must redefine their defense strategy and shift-left to track the attacker infrastructure itself—monitoring the exact IP layer locations where adversaries build and control their campaigns. Deep content inspection remains essential, but securing the modern edge requires establishing the context and intent of a connection before a session is established.

To achieve this goal, organizations must move beyond the limitations of static defense and adopt a modern security blueprint:

• Proactive protection against attacker infrastructure: While high-quality threat feeds remain essential for SOC investigations and incident response, relying on them for frontline, real-time prevention creates major blind spots. Instead, security teams must use real-world, global telemetry to proactively identify and block connections to attacker-controlled hosts before requesting a URL or file.
• Zero trust principles applied to the network layer: An IP address without a negative reputation does not equal a safe connection. Continuous verification requires extending zero trust down to the network foundation. It validates the real-time behavior and intent of every single session to ensure attackers cannot hide in the contextual vacuum of the IP layer.  
• Reducing the attack surface with rich contextual attributes: Traditional IP blocking is like a blunt instrument that creates unacceptable false positives and alert fatigue. To modernize the edge, security teams need deep, attribute-based visibility across the entire Internet address space to reduce noise and replace legacy IP feeds entirely.  

By moving away from point-in-time assumptions and embracing real-time, inline protection, security leaders can reclaim the advantage at the network foundation.

To see how these evasion tactics operate in the wild, read the latest Unit 42 report, Attackers Are Evading Threat Prevention at the Internet Edge. You’ll find this report valuable in understanding the systemic gaps in legacy risk models and learning why continuous verification must be our new mandate.
