The Rise of Fractional CISOs: Why More Businesses Are Moving Toward vCISO Models

The way businesses approach cybersecurity leadership is changing quickly. Rising security demands, tighter budgets, and increasing pressure around risk and compliance are making organizations rethink how they bring security expertise into the business. The shift is no longer only about reducing costs. It is about finding a practical way to access experienced security guidance without committing to a full-time executive hire.

A report from Hitech Partners notes that companies with fewer than 500 employees are more likely to use vCISO services for sales credibility and strategic guidance. In comparison, larger companies with more than 1,000 employees often turn to vCISOs to address insider threats and event remediation.

This shift raises a few important questions. What is driving the growing demand for fractional CISOs and vCISO services? What challenges are businesses trying to solve through this model? And as security needs continue to evolve, what should companies look for in a trusted external security advisor?

In this Expert Opinion Q&A, Ace Cloud Hosting spoke with Kayne McGladrey, CISSP, author of the GRC Maturity Model, Senior IEEE Member, and cybersecurity advisor. With 30+ keynote speeches at events such as RSA, Gartner, ISC2, and ISACA, Kayne is known for helping organizations connect security risk with business value.

Drawing on his experience in executive advisory, governance, breach response, and security leadership, he shares a practical perspective on why more businesses are adopting vCISO models and where this approach can deliver the most value.

Kayne shared his views on the rise of fractional CISOs, the business and governance challenges organizations are trying to solve, how companies can align security with broader goals, and what leaders should consider before making the shift to a vCISO-led model.

1. What is driving the growing demand for fractional CISOs and vCISO services today?

Cost is a primary reason, but companies are moving past just budget cuts. While organizations see security as a cost center, the rising personal liability for full-time CISOs has fundamentally altered the market. Recent legal precedents show executives facing individual scrutiny and potential criminal charges for how they handle breaches, making the traditional CISO role increasingly risky.

Many friends of mine would rather have fractional arrangements to avoid direct accountability for disclosure failures or regulatory penalties. This creates a supply-side dynamic where top talent opts for consulting roles over full-time employment with a single company.

The number of AI-driven threats we’ll see for the rest of 2026 demands specialized knowledge that generalist internal teams often lack. Companies can access this high-level strategic guidance on demand without the overhead of a six-figure salary plus benefits.

The vCISO model offers customers the flexibility to scale their security leadership up or down based on their immediate needs, like getting ready for an audit or working through M&A activity, rather than maintaining a permanent executive presence.

2. What are the biggest cybersecurity and governance challenges that organizations are trying to solve through vCISO models?

Cost reduction, access to specialized expertise, and mitigating personal liability risks for security leaders. Organizations use vCISOs to help meet their regulatory mandates without the overhead of a full-time executive salary. This model provides strategic guidance while avoiding the high costs and legal exposures associated with traditional CISO roles in an increasingly litigious environment.

vCISOs also have cross-industry insights, allowing companies to benchmark against peers and implement proven frameworks like NIST or ISO efficiently. This addresses the governance gap where internal staff focus on execution while leadership requires high-level direction.

However, this approach introduces accountability challenges during incidents, requiring clear contracts to define the advisory nature of the role versus internal ownership.

3. How can a fractional CISO help businesses align cybersecurity with overall business and risk management goals?

Alignment depends heavily on organizational commitment and the vCISO’s communication style, not just their presence. A fractional CISO is an outsider who cannot reasonably be expected to immediately grasp internal politics better than the existing leadership. True alignment requires meaningful conversations, mutual agreements, and a willingness from both sides to develop business risk management skills.

The vCISO can help to translate technical threats into business impact, but executives must actively partner with them and follow reasonable requests. Without this partnership, expecting magical results is unrealistic.

The vCISO provides the strategic roadmap, but internal leaders must champion both the necessary cultural shifts and the resource allocations. Success hinges on the Board and management accepting the vCISO as a strategic partner rather than just a compliance checkbox.

5. With AI adoption and compliance requirements increasing, how do you see the role of vCISOs evolving in the coming years?

The vCISO role’s going to change in a couple of ways, in response to defending against AI-powered external threats and governing internal AI adoption, including expansive shadow AI risk. External threats are increasing rapidly from tools like Anthropic’s Mythos and James Kettle’s open source “terminator” (to be released at Hacker Summer Camp 2026).

vCISOs with cross-client visibility can identify patterns faster than isolated internal teams and provide actionable guidance for what works for meaningful risk reduction, not just checkbox compliance.

At the same time, organizations deploying AI internally continue to lack governance for data integrity, model security, or unauthorized tool usage. vCISOs can partner with the business leaders to draft policies and propose controls that balance innovation with risk mitigation.

Numerous agencies and regulatory bodies are issuing increasingly specific guidance on AI threats, and compliance frameworks increasingly include AI-specific controls. The vCISO can help to interpret these technical requirements into an actionable strategy.

6. What should organizations look for when choosing a fractional CISO or cybersecurity advisor?

The ideal candidate balances strategic vision with practical operational knowledge, acting as a true business partner, rather than just a vendor. Organizations should fast-track candidates with proven full-time CISO experience in similar industries, confirmed by references.

Look for a clear track record of managing audits like SOC 2 or FedRAMP, not just technical implementation. An effective vCISO must have strong executive communication skills to translate complex risks into business language for boards. Crucially, verify their capacity to handle multiple clients without compromising response times during incidents.

Avoid those who push for you to use their proprietary tools, as this is often an inherent conflict of interest where the vCISO is white-labeling a vendor’s software and getting a commission. And make sure that the contract explicitly defines accountability boundaries, particularly around incident response and liability.

7. What advice would you give to businesses considering a shift toward a vCISO-led cybersecurity strategy?

Series C startups (and earlier), and firms in less-regulated industries (like a car dealership trying to deal with GLBA), are the best candidates for a vCISO model. These organizations often lack the budget for a six-figure executive but still have compliance mandates that require a designated security leader. A vCISO represents the necessary strategic oversight and audit readiness without the overhead of a full-time salary and benefits.

That said, don’t treat the vCISO as a substitute for building internal security maturity. Use the engagement to develop your team’s capabilities, not just to outsource the thinking. Insist on documentation, playbooks, and knowledge transfer from day one.

Define clear success metrics tied to business outcomes, not just technical checkboxes. And plan your exit before you start. Know what it looks like when you’ve outgrown the fractional model and need a full-time leader, and make sure the vCISO sets you up for that transition rather than creating dependency.

Finally, get executive buy-in before bringing anyone on. A vCISO without board support and budget authority is just an expensive consultant whose recommendations gather dust.

Build Security Leadership That Fits the Business

The rise of fractional CISOs reflects a broader shift in how businesses think about security leadership. Many organizations need experienced leadership, stronger planning, and better support for risk and compliance, but they do not always need a full-time executive to achieve them. What they need is the right level of leadership at the right stage of growth.

As Kayne McGladrey highlights, the best results come when businesses treat a vCISO as a true partner, not just an outside advisor. Companies that set clear goals, build internal ownership, and choose someone with the right experience will be in a much better position to strengthen their security approach over time.
