GenAI in 2025: Why Your CISO Needs to Be the AI Security Maestro
Generative AI (GenAI) is no longer futuristic; it’s already deployed across most organizations, leading use cases in data analysis, personalized chat experiences, and research, according to Gartner’s 2025 findings. Business units are embracing this shift, but security teams are racing to keep pace.
Over 40% of Security and Risk Management (SRM) leaders already use GenAI within cybersecurity for tasks like threat detection and incident response. However, over 40% also admit to critical skills gaps limiting their ability to support GenAI innovation securely.
This article explores how CISOs can lead in closing those gaps, shaping GenAI policy, and building a foundation for safe, strategic AI integration.
Why GenAI Demands Cybersecurity Leadership—Not Just Support
GenAI’s spread introduces new security risks many businesses aren’t prepared for. Gartner’s research shows most cybersecurity teams lack full control over GenAI tool selection, use, or management. This creates a dangerous gap.
Without early security leader involvement, GenAI tools can be misused, leading to data leaks, unauthorized access, or unreliable outputs. Despite these risks, cybersecurity is often seen as a support function, not a decision-maker.
CISOs must step in and lead. By actively participating in GenAI projects, they can define safe usage, create clear policies, and ensure security is part of every decision—not an afterthought.
The Two-Way Street: How GenAI is Reshaping Cybersecurity Operations
GenAI isn’t just a business tool; it’s transforming cybersecurity operations. As organizations deploy GenAI for data analysis, chat-based support, and research, security teams manage its risks and secure its use.
In response, security teams are adopting GenAI for faster threat detection, incident summarization, and investigation support. This isn’t happening in isolation; over half of cybersecurity leaders now work with data, privacy, and compliance teams on GenAI issues.
This cross-functional shift changes the CISO’s role. Instead of owning all GenAI oversight, security leaders must focus on enabling secure adoption—setting guardrails, defining standards, and partnering with other functions to manage shared risks.
Bridging the Influence Gap: From Advisor to Decision Maker
While SRM leaders increasingly influence GenAI discussions, they rarely control final decisions. Gartner reports over 70% of cybersecurity teams influence GenAI choices, but only 24% have final authority to approve or reject GenAI use based on security. Just 26% can approve or block GenAI tools for pilot testing.
This gap creates risk. When cybersecurity input is merely advisory, GenAI tools may be adopted without proper controls, inviting threats, data exposure, and compliance issues.
CISOs need to shift from reactive advisors to active decision-makers. They should:
- Set clear policies on GenAI usage.
- Lead response plans for AI-related incidents.
- Help evaluate and approve GenAI vendors.
The Power of Collaboration: Crafting Policies Together
As GenAI adoption grows, security policies can’t be built in isolation. Gartner states that co-creating GenAI policies with other business functions (data, privacy, compliance) significantly improves secure and timely adoption.
Collaborative policy development makes policies more practical, understood, and enforceable. It also positions security teams as partners, not roadblocks.
CISOs should lead GenAI policy development, but they must include voices from across the organization. This aligns security standards with operational realities, making policies accessible and usable.
Closing the GenAI Cybersecurity Skills Gap: A 2025 Imperative
As GenAI embeds into cybersecurity, many teams struggle to keep pace. Securing AI systems requires different tools and thinking, and many organizations aren’t prepared.
The World Economic Forum’s Global Cybersecurity Outlook 2025 shows the cyber skills gap worsening, growing 8% since 2024. Two out of three organizations lack enough skilled people, and only 14% feel confident in their current skills.
This shortage is concerning for CISOs managing GenAI adoption. Traditional hiring and certifications don’t always reflect AI environment needs. CISOs should seek adaptability, critical thinking, and logical reasoning—skills supporting fast learning and decision-making in unfamiliar scenarios.
To close this gap, hands-on learning and targeted practice are essential.
Aligning with the C-Suite: Speaking Their Language
Boards and CIOs see GenAI’s value but worry about different risks. Gartner notes Boards prioritize security threats and data privacy, while CIOs focus on AI errors, misinformation, and intellectual property risks.
For CISOs, one message doesn’t fit all. To gain support, security leaders must speak each audience’s language. Boards want to know how GenAI will be secured. CIOs want to understand how risks like biased outputs or “hallucinated” results will be managed.
Addressing these concerns clearly and separately builds stronger trust and influence at the executive level.
Practical Tools to Accelerate Secure GenAI Adoption
As GenAI becomes part of daily business, security leaders need tools that both enable adoption and manage risks. Gartner emphasizes cybersecurity should support innovation with guidance, oversight, and training.
CISOs must equip teams with tools that raise awareness, test real-world behavior, and enforce security standards. This includes:
- Simulating GenAI-related threats (AI-generated phishing, smishing, quishing).
- Tracking risky user behavior in response to these threats.
- Benchmarking human risk levels across teams to focus resources.
The CISO’s Ultimate Role: Leading Safe GenAI Adoption
As Generative AI becomes central to enterprise innovation, CISOs face a pivotal transformation—from cautious gatekeepers to bold enablers of secure and ethical integration. Gartner underscores the importance of Security and Risk Management (SRM) leaders taking the helm in steering GenAI strategy.
To effectively lead this shift, today’s CISOs must:
- Embed early in GenAI planning: Influence tool selection and architecture from the ground up.
- Forge cross-functional partnerships: Work hand-in-hand with legal, privacy, and data governance teams to craft sound, adaptive policies.
- Bridge internal skill gaps: Champion tailored upskilling programs that empower teams to work securely with GenAI tools.
- Leverage simulation and risk measurement: Adopt platforms that test GenAI vulnerabilities and assess human error risk in real time.
The future of responsible GenAI use depends on visionary security leadership. The question isn’t whether GenAI will reshape your enterprise—it’s whether you’re ready to lead the charge.
