What Keeps CISOs Up at Night: Cybersecurity Risks in 2026

Gary Perkins, Chief Information Security Officer (CISO)

Key Takeaways

• The gap between perceived security and actual risk continues to widen, and attackers only need one successful entry point to cause significant damage.
• AI is accelerating both cyber attacks and internal risk, with “Shadow AI” creating new exposure that many organizations are not fully controlling.
• Identity and data are now the primary targets, with compromised credentials leading to deeper access and more damaging breaches.
• Increasing complexity, human error, and limited internal resources make it difficult for organizations to keep pace, highlighting the need for a more unified security approach.

Cybersecurity challenges in 2026 are evolving faster than most organizations can keep up with, and what keeps CISOs up at night is no longer a single threat, but the growing complexity of the entire security landscape. From AI-driven threats to identity-based attacks, CISOs are facing increasing pressure to manage risk while enabling business growth.

To be honest, I never have problems sleeping. I’ve been responsible for infrastructure and people for so long that I’ve developed a thick skin. I make a point of hiring the right teams and empowering them to do their jobs. When you have the right people in the right seats, you trust the process. However, I do think about a number of things, as do my colleagues in the industry. We are operating in a climate where the gap between perceived security posture and actual risk is widening, and the reality is that attackers only need to be right once.

Here is what is weighing on the minds of CISOs in 2026.

AI in Cybersecurity: Risks, Shadow AI, and Emerging Threats

AI is reshaping both sides of the threat landscape.

The most immediate shift we’ve seen is the dual-use nature of Artificial Intelligence. It is the primary engine for both defense and offense. AI-driven attacks are increasing in speed, scale, and sophistication, often moving faster than a human-led SOC can react. We are seeing AI agents operating autonomously with unclear oversight or controls, which leads to a dangerous overreliance on tools without fully understanding their security implications.

Within our own walls, “Shadow AI” has become the new Shadow IT. Employees are eager to boost productivity, often granting AI tools excessive permissions to sensitive data.

 Whether it’s leaking proprietary data through AI prompts or poorly managed integrations, the internal risk is massive. This is compounded by the fact that adversaries are using these same technologies to craft near-perfect phishing and deepfake campaigns. It has become nearly impossible for the average person to distinguish real versus AI-generated communications. This expanding attack surface is moving faster than it can be secured.

Identity-Based Attacks and Data Breach Risks

Identity has become the easiest path for attackers to gain access.

In 2026, identity is the primary attack vector. Attackers are no longer breaking in. They are logging in using compromised credentials. We see a persistent lack of visibility into who has access to what, fueled by overprivileged accounts across hybrid environments. This is often exacerbated by API and cloud misconfigurations that expose critical systems to the open web.

When an identity is compromised, the results are more damaging than they used to be. Ransomware has evolved into multi-extortion and data destruction. Data exfiltration is now the primary threat, as the explosion of exposed personal and sensitive data can ruin a brand’s reputation permanently. Even when organizations try to do the right thing, backup strategies often fail when they are actually needed (has anyone actually tested how long it will take to restore the entire environment to understand how long it will take?). Despite the ethical and legal pressure, many organizations still find themselves choosing to pay ransoms under the weight of total operational collapse.

Human Error and Security Team Burnout

Technology is not the weakest link. It’s often said that people are.

Despite all the technical advances, human error continues to be the root cause of most breaches. Social engineering has become more convincing and personalized, and phishing still outperforms even the best technical controls. We are also dealing with employee fatigue, where constant security friction leads to poor decisions. Security awareness programs simply aren’t keeping pace with the evolving threats.

This pressure isn’t just on the end-users, it’s on the security professionals as well.  Alert fatigue is overwhelming SOC teams, and budget constraints have historically forced many to try to “do more with less.” This leads to increased dwell time because stealthier attacks, often involving attackers “living off the land” using legitimate system tools, go unnoticed for months.

Security Tool Sprawl, Cloud Risk, and Emerging Quantum Risks

Complexity is creating gaps faster than organizations can close them.

The rapid pace of technological change is outpacing many security programs. Tool sprawl has created a landscape of complexity and blind spots, with a distinct lack of integration between security tools. Many CISOs find it difficult to operationalize their security investments into measurable outcomes. We are constantly balancing innovation with risk management while trying to secure remote and hybrid work environments.

This sprawl includes endpoint sprawl, unmanaged devices, and the rise of unmanaged IoT. Even where Zero Trust architectures are planned, the trust assumptions are often not fully implemented. We are also looking at the “Quantum” horizon. Quantum computing is threatening current encryption standards, and the uncertainty around timelines for quantum-safe cryptography adoption creates a “harvest now, decrypt later” risk for sensitive data.

Critical Infrastructure, Supply Chain Risk, and Business Resilience

Risk no longer stops at your organization’s perimeter.

We no longer operate in a vacuum. Critical infrastructure has become a primary target for state-sponsored cyber activity, driven by geopolitical tensions. Supply chain attacks are impacting trusted vendors and partners, and third-party risk has expanded beyond our direct visibility.

We’ve seen how global outages can disrupt business operations even without a direct “cyber” incident. There is a worrying dependency on cloud providers and SaaS platforms without enough resilience planning for non-security operational failures. When an incident does occur, many find they have fragmented response capabilities and a lack of properly tested recovery plans. The fallout is more than technical, it involves legal and regulatory pressure, customer trust erosion, and media amplification that can tank a company’s valuation overnight.

Aligning Cybersecurity with Business Strategy and Board-Level Risk

Security only works when it aligns with how the business operates.

Finally, there is the challenge of the boardroom. CISOs still struggle to communicate risk in business terms and measure the ROI of security investments. We need to align security strategy with business objectives so that security is seen as a business enabler rather than a blocker.

Continuous change makes it hard to maintain a stable security baseline. There is a constant fear of falling behind competitors in technology adoption, which leads to the pressure to adopt AI without fully understanding the risks involved. We are facing increasing regulatory complexity and the potential for significant legal fallout after an incident.

How to Close the Cybersecurity Gap and Strengthen your Defense Strategy

Closing the gap requires more than tools; it requires alignment and coverage.

The reality of this industry is that the landscape is too broad for any one internal team to cover every corner, every hour of the day. Maintaining a stable baseline in a state of continuous change is a monumental task. Closing this gap is ultimately what keeps CISOs up at night, and why a more unified approach to security is no longer optional.  That is why you need a partner that provides end-to-end cybersecurity solutions. At CISO Global, we focus on the entire lifecycle of risk, from governance and architecture to 24/7 monitoring and response. By integrating these fragmented pieces into a single, cohesive strategy, we ensure you are covered evenings, weekends, and everywhere in between. It’s the only way to  close the gap between perceived security and actual risk, and to finally operate with confidence that  your environment is covered.
