Technology leadership comes in different flavors for growing businesses. Many mid-market firms reach a point where they need high-level guidance in IT strategy or cybersecurity, but hiring full-time C-suite executives may be impractical. This is where fractional or virtual CIOs and CISOs come in. In fact, over 60% of small and mid-sized businesses now use fractional CIO services to shape their IT strategy, and demand for fractional CISOs (vCISOs) is surging as companies seek expert security guidance without a full-time hire. But what exactly do these roles entail, and which one (or both) does your organization need?
In this post, we’ll clarify the definitions of a Fractional CIO vs. a Fractional CISO, outline their key differences, and discuss when to hire each – or even when you might need both—depending on your business’s situation.
What Is a Fractional CIO?
A Fractional CIO (Chief Information Officer) is essentially a part-time or on-demand IT executive who provides strategic technology leadership to an organization without being a full-time employee. In other words, the fractional CIO offers the expertise and vision of a seasoned CIO on a flexible basis (e.g. a few days per month or for a specific project). This allows businesses to access high-level IT guidance “without the associated level of overhead” of a full-time CIO role. Fractional CIOs often work with multiple companies, typically small or mid-sized businesses that cannot justify a full-time CIO but still need to align technology with their business goals.
What does a Fractional CIO do? In practice, they perform many of the same functions as an in-house CIO, just not 40 hours a week. A fractional CIO will help define and execute IT strategy, ensure that the company’s technology roadmap supports its business objectives, and oversee major IT initiatives or transformations. They might evaluate your IT infrastructure and processes, recommend improvements or new technologies, manage IT budgeting and staffing plans, and make sure IT investments deliver business value. Essentially, the fractional CIO’s mandate is strategic IT leadership: making sure technology is enabling growth, efficiency, and competitiveness for the business. For example, if a company is planning a digital transformation or needs to integrate systems after an acquisition, a fractional CIO can craft the plan and guide the implementation. This role is typically business-focused—looking at how tech can serve the business needs – and involves coordinating across departments to align IT with corporate strategy.
It’s no surprise that fractional CIO services have become popular. They offer cost-effective flexibility. You get an experienced technology executive “on retainer” to steer your IT ship, without paying a full-time executive salary. A recent Gartner report noted that 64% of SMBs have adopted fractional CIOs to improve their IT strategy. This trend reflects how even smaller companies now recognize the need for strategic IT direction yet prefer to outsource that leadership for budget reasons. In short, a fractional CIO is the strategic IT partner for your business – helping plan and execute technology initiatives that propel growth, all on a schedule and budget tailored to your needs.

What Is a Fractional CISO?
A Fractional CISO (Chief Information Security Officer), also known as a Virtual CISO (vCISO) or CISO-as-a-Service, is a part-time security executive who oversees an organization’s cybersecurity strategy and risk management on an outsourced basis. Rather than hiring a full-time CISO to sit in your office, you engage a fractional CISO – an external professional security expert—to provide C-level guidance on protecting the company’s information assets. This arrangement gives companies (especially those without in-house security leadership) access to high-level cybersecurity expertise without incurring the cost of a full-time hire.
What does a Fractional CISO do? Much like a traditional CISO, a fractional CISO is responsible for all things cybersecurity—but they do it on a flexible schedule. Their duties typically include assessing the organization’s security posture and risks, developing and implementing security policies and procedures, ensuring compliance with relevant regulations (for example, GDPR, HIPAA, or PCI standards), leading incident response planning, and advising executives on cybersecurity threats. They may conduct security awareness training for staff, review technical defenses (like firewalls, endpoint protection, etc.), and prioritize security initiatives. Essentially, the fractional CISO’s mandate is protecting the organization’s data and IT systems from breaches and cyber threats and doing so in a way that aligns with the company’s business needs and compliance requirements.
Fractional CISOs are often brought in when a company reaches a point where security can no longer be handled ad-hoc by the IT team. Many mid-market firms operate without any CISO at all—in fact about 64% of SMBs have no designated CISO due to cost or resource constraints. A fractional CISO fills this leadership gap by providing top-tier security guidance on a part-time basis. This has rapidly become mainstream: studies show virtual CISO services have “moved from niche to mainstream” with a threefold increase in adoption over a year—67% of service providers now offer vCISO services, up from 21% the year prior—driven by high demand from SMB clients for security expertise. The fractional CISO gives organizations the benefit of a seasoned security leader who can establish a robust security program, without the six-figure cost and commitment of hiring a full-time CISO. It’s a flexible way to get a “security captain” on board to navigate today’s threat landscape and compliance obligations.
Key Differences Between a Fractional CIO and a Fractional CISO
Both fractional CIOs and CISOs are outsourced executive roles helping organizations with technology leadership – but their focus and expertise are very different. A simple way to remember the distinction: the CIO (even a fractional one) is a strategic business-focused technology leader, whereas the CISO is a security-focused leader. Here are the key differences:
- Primary Focus: A fractional CIO’s primary mission is leveraging technology to drive business innovation and efficiency. They look at how IT can support growth, streamline operations, and add value to the business. In contrast, a fractional CISO’s mission is to protect the business’s information and systems – their focus is on cybersecurity risk reduction, data protection, and compliance. In short, CIO = making sure IT accelerates the business, while CISO = making sure the business is defended from cyber threats.
- Responsibilities: While there may be some overlap in general IT oversight, the day-to-day responsibilities highlight their different domains. A fractional CIO might be responsible for planning long-term IT investments, choosing and implementing software or cloud solutions, managing IT staff or vendors, integrating technology across departments, and ensuring the IT roadmap aligns with business strategy. For example, a CIO will lead digital transformation projects or decide on adopting a new ERP system. On the other hand, a fractional CISO will be responsible for establishing security policies, monitoring for threats and vulnerabilities, leading incident response processes, implementing cybersecurity tools (like encryption, intrusion detection, etc.), and ensuring the company meets security standards and regulations. A CISO is thinking in terms of risk management and defense – e.g. “How do we secure that new ERP system? Do we have proper access controls and an incident plan if something goes wrong?” Meanwhile, the CIO is thinking “How do we deploy and optimize that system to improve operations and ROI?” Each role approaches the same IT environment from a distinct angle.
- Skillsets & Background: Because of these focus areas, the background and expertise of a CIO vs. CISO typically differ. A CIO usually has a broad IT management and business background – they understand technology and how to apply it strategically for business outcomes. Many have experience in IT operations, project management, and often hold business-related qualifications (some even have MBAs), since the role requires translating between technical possibilities and business objectives. A CISO, in contrast, tends to have a deeper technical cybersecurity and risk management background. They are experts in areas like information security, network security, compliance frameworks, and often hold certifications like CISSP or CISM that are specific to security management. In short, the CIO is a business-savvy technologist, whereas the CISO is a security specialist. Both are leadership roles, but one is oriented toward innovation and efficiency, the other toward protection and risk mitigation.
- Reporting Structure and Scope: In many organizations, the CIO is higher in the hierarchy – often reporting directly to the CEO or COO – because the CIO oversees all of IT and how it supports business strategy. The CISO’s scope is narrower (focused on security), and a CISO will sometimes report to the CIO or to another executive like a CTO or even directly to the CEO depending on the company’s emphasis on security. This reflects how the CIO has a broader charter (all information and technology resources), while the CISO is specialized (information security). They also collaborate: the CISO often works under or with the CIO to ensure security is woven into all IT initiatives. But there is a built-in checks-and-balances too – the CIO might own the IT budget and projects, and the CISO makes sure the risks are managed and security isn’t overlooked in those projects. Both roles are critical, especially as a company grows: the CIO to make sure tech investments drive value, and the CISO to ensure those tech advances don’t introduce undue risk.
In summary, the CIO looks at “are we using the right technologies to move the business forward?”, and the CISO asks “are we secured against threats and meeting our security obligations?”. The fractional CIO is your strategist for what technology to use and why, and the fractional CISO is your strategist for keeping that technology and data safe. Next, let’s look at how to decide which of these fractional leaders you might need, based on common business scenarios.

When to Hire a Fractional CIO
How do you know if your organization could benefit from a fractional CIO? Here are some common situations where engaging a part-time CIO makes sense:
- No Strategic IT Leader in Place (and IT is Becoming Overwhelming): If you’re a small or mid-sized business without a full-time CIO, you might notice that IT decisions are being made ad-hoc by various managers or your overloaded IT team. Perhaps your IT infrastructure has grown over time and you lack a unifying strategy. This is a classic sign you need a higher-level IT leader to coordinate and plan. A fractional CIO can step in to provide that strategic direction – ensuring your technology efforts are not just reactive but proactively supporting your business plan. This is especially crucial if technology is critical to your operations (which it is for most modern businesses). Rather than hiring a costly executive, a part-time CIO gives you that guidance in a tailored, affordable way. In fact, fractional CIOs are ideal for SMBs that need IT leadership but can’t justify a full-time CIO’s expense.
- Budget Constraints – Cost-Effective Leadership: Related to the above, maybe you recognize the need for a CIO but simply cannot afford one full-time. A top CIO can command a six-figure salary (plus benefits), which is out of reach for many mid-market companies. A fractional CIO is a cost-effective alternative. You get a CIO’s expertise at a fraction of the cost, paying only for the time and services you need. If you’re watching the bottom line but still want to leverage technology for growth, a fractional CIO is an excellent solution to “access executive-level expertise without committing to a permanent C-suite hire”. This allows smaller enterprises to compete with larger firms in IT strategy by “renting” a highly experienced CIO on a part-time basis, stretching your budget much further.
- Major IT Projects or Transitions: If your company is about to undertake a significant technology project – such as **implementing a new ERP/CRM system, migrating to the cloud, rolling out new digital products, or undergoing a big digital transformation – having a CIO-level strategist is critical for success. These projects cut across the entire business and carry high stakes. A fractional CIO can provide the planning and oversight to make sure the initiative meets its goals. Similarly, if you’re in a period of change like a merger or acquisition, or restructuring of the IT department, a fractional CIO can guide the transition. Companies undergoing IT transitions or complex projects often bring in a fractional CIO short-term to lend expertise and keep things on track. Once the project is complete or the transition is stabilized, the CIO’s involvement can scale down.
- Rapid Growth and Scaling Needs: Your business might be expanding – opening new locations, launching e-commerce, or growing the workforce. With growth comes more IT complexity and higher demands on your systems. This is a good time to get a fractional CIO if you don’t have a CIO yet. They will ensure your IT roadmap scales with your business. For example, during rapid growth a fractional CIO can plan out how to upgrade infrastructure, implement scalable cloud solutions, and put in place the right IT organization and governance for a larger enterprise. They basically future-proof your IT for the next stage of the company. If you “don’t know what you don’t know” about scaling technology, a fractional CIO will illuminate the path and prevent costly missteps.
- Interim CIO Gap or Executive Advisory: Maybe your previous CIO or IT director left, and you have a leadership gap while you search for a replacement. A fractional CIO can act as an interim CIO to maintain continuity. They’ll keep critical IT operations running and important projects moving forward. Even if you have a strong IT manager in-house, they may not have the strategic experience a CIO has – the fractional CIO can mentor them and provide high-level oversight until a permanent hire is made (or indefinitely if you decide a fractional model works better). Additionally, sometimes companies have a capable IT team but would still like outside expert advice on big decisions; a fractional CIO can serve as a senior advisor who periodically reviews your IT strategy and gives guidance, even if you don’t need hands-on management every week.
In short, hire a fractional CIO when you need top-tier IT leadership and strategy, but either your budget, size, or situation doesn’t warrant a full-time CIO. This could be at the early stages of needing IT direction, during a pivotal project, or as a long-term part-time solution for strategic oversight. Many mid-market businesses start with a fractional CIO to set up their IT strategy and processes, then maybe later (years down the road) decide if/when a full-time CIO is necessary. The fractional CIO can also help determine that tipping point.
When to Hire a Fractional CISO
Now, what are the telltale signs that your organization should bring in a fractional CISO (virtual CISO)? Cybersecurity is an area where many companies delay leadership until something forces the issue. Here are common scenarios where a fractional CISO is highly valuable:
- Heightened Cyber Risks and No In-House Security Leader: Perhaps your business has been handling security informally – the IT manager handles the firewall, you outsource antivirus, etc. – but you have no dedicated security officer. As cyber threats (ransomware, data breaches, etc.) grow, this lack of specialized leadership becomes risky. If you don’t have a CISO or security expert on staff, you probably need one once you start worrying about things like sensitive customer data, advanced threats, or client security assessments. The reality is most SMBs don’t have a CISO (64% operate without one) due to cost or talent shortages. A fractional CISO is the ideal solution to “bridge that gap by providing affordable access to top-tier security expertise”. When you know security is important but can’t justify a full-time CISO, bring in a fractional CISO to establish and run a proper security program part-time.
- After a Security Incident or Proactive Risk Management: It’s unfortunate, but many companies realize they need a CISO only after a serious security incident (like a breach or major network outage) or a series of close calls. If you’ve experienced a cybersecurity incident and lacked the leadership to respond effectively, a fractional CISO can be brought in to remediate the situation and prevent future incidents. They will investigate what happened, tighten up defenses, and put formal incident response plans in place. Even better is to be proactive – if you’re increasingly concerned that “we’ve been lucky so far, but we have vulnerabilities”, that is a sign to get a security chief on board now. A fractional CISO will perform a risk assessment, identify your biggest threats/gaps, and systematically improve your security posture. Essentially, whenever security is keeping you up at night (or your IT team admits they’re out of their depth on security matters), it’s time to engage a fractional CISO to sleep better knowing an expert is overseeing this area.
- Compliance or Client Requirements: Many businesses reach a point where compliance requirements force the issue of dedicated security leadership. For example, if you must comply with regulations like HIPAA (health data), PCI-DSS (payment card data), GDPR, CMMC, or any number of industry cybersecurity standards, a fractional CISO is incredibly useful. They have the expertise to interpret the requirements and build the needed policies and controls. A common use case is bringing in a fractional CISO to lead a compliance project – say you need to get SOC 2 certification for customer contracts or pass a big client’s security audit. The vCISO will drive that effort, get your policies/documentation in order, implement controls, and see you through the audit. Afterward, you might keep them on a lighter basis to maintain compliance. Likewise, sometimes large enterprise customers or partners might ask, “Who is your security officer?” If you’re an SMB without one, having a fractional CISO on-call can satisfy those due diligence concerns. They essentially provide credibility and accountability on security to external stakeholders.
- During Company Growth or Technology Changes (Security Falling Behind): Your company might be rapidly adopting new technologies, moving to cloud services, or storing more and more data – but your security measures haven’t kept pace. If you worry that security is lagging behind your IT growth, a fractional CISO can step in to build a security framework from the ground up. For organizations early in their security maturity, a fractional CISO will create the foundational policies and procedures (incident response plans, access management policies, security training programs, etc.) to get you up to a reasonable standard. They essentially “accelerate your cybersecurity maturity” so that as you grow, you’re not leaving glaring holes open for attackers. This scenario is common for startups or mid-sized firms that suddenly scale – at say 50 employees security was ad-hoc, but at 200 employees with more data and remote work, you need formal security leadership. The fractional CISO can establish that security roadmap and even mentor your IT staff on security best practices going forward.
- Existing IT Team Needs Specialized Guidance: Maybe you already have a CIO or a solid IT director, but they are not a security specialist. In this case, you could augment your team with a fractional CISO rather than expecting your CIO to wear the CISO hat (which can be risky if they’re not trained for it). The fractional CISO will partner with your IT leadership to focus on security while the CIO focuses on broader IT. This combo can work well: for example, your IT team handles day-to-day security device management, but the fractional CISO sets the strategy, reviews configurations, and is on-call for major incidents. They might meet with your team monthly or quarterly to review security metrics, help prioritize new security investments, and ensure nothing is slipping through cracks. Think of it like having a coach or advisor specifically for cybersecurity, who elevates your internal team’s efforts. If you want an expert eye on security without hiring a whole CISO department, this is a great approach.
In summary, engage a fractional CISO when your organization has non-trivial security risks or requirements that aren’t being addressed by current staff, and you need expert leadership to drive your cybersecurity strategy. This often coincides with reaching a certain size, handling sensitive data, experiencing an incident, or facing compliance mandates. A fractional CISO brings peace of mind that someone with deep expertise is at the helm of your security program – and they’ll tailor their involvement to what you actually need (from a heavy lift like building a program from scratch to a lighter ongoing advisory role). Given the explosion of cyber threats, it’s often better to be early in getting a CISO’s guidance fractionally than too late after a breach.
When Might You Need Both Roles?
We’ve discussed fractional CIO vs. fractional CISO as distinct options – but many organizations ultimately find they need both kinds of leadership, because CIO and CISO roles complement each other. In a mid-market company, it’s not an either/or choice long-term; it’s a matter of sequence and focus. Often, companies will hire one fractional executive first, depending on their most pressing needs, and later add the other role once the company’s maturity and challenges expand.
For example, a growing business might initially bring on a fractional CIO to get their IT strategy and infrastructure optimized. The CIO helps implement new systems, move to the cloud, and align IT with growth plans. After a year or two, the company’s technology is in good shape – but now they’re big enough to attract cyber threats or need to comply with stricter security standards. At that point, the pain point shifts to security, and they engage a fractional CISO to fortify defenses and formalize cybersecurity practices. Conversely, a company could start with a fractional CISO if they operate in a highly regulated industry or recently had a breach. The vCISO secures the environment and builds risk management processes. Once security is stable, the business might turn attention to broader IT improvements and bring in a fractional CIO to drive digital transformation and efficiency.
Mid-market firms often hire one before the other depending on their maturity and immediate priorities – but eventually, having both a CIO and CISO (even fractionally) can provide a balanced approach. The fractional CIO and CISO will work hand-in-hand: one is charting the course for technology to advance the business, the other is ensuring that voyage is safe from storms. In fact, using an “outsourced model for certain leadership roles” is increasingly common. Just as companies use fractional CFOs or CIOs, they are now adding fractional CISOs to the mix. If your company values flexibility in leadership (paying for what you need, when you need it), you might already have a fractional CIO guiding IT strategy and a fractional CISO safeguarding security. This combination gives you robust executive oversight in both arenas without the full-time executive headcount.
It’s worth noting that the CIO and CISO must collaborate closely (whether they are fractional or full-time). IT strategy and security are deeply intertwined. For instance, if the CIO decides to implement a new data analytics platform, the CISO should be involved to ensure proper data security and privacy controls. In an outsourced scenario, your fractional CIO and CISO can periodically get together (with your CEO/board if needed) to jointly align on initiatives – ensuring that innovation and protection go hand in hand. Many providers (Meriplex included) offer both fractional CIO and CISO services, precisely because mid-sized organizations often eventually require an integrated approach to technology leadership. By having both roles available on a flexible basis, you can dial up or down the expertise in each area as your business evolves.

Conclusion
A fractional CIO and a fractional CISO address different leadership gaps – one in IT strategy, one in cybersecurity – but they are complementary. Companies that leverage both will have the advantage of strategic IT direction and strong security oversight at the same time, which in today’s environment is increasingly seen as a best practice for sustainable growth. If you start with one, continually reassess as you grow whether it’s time to add the other. Many organizations report that having both roles filled (even part-time) dramatically improved their confidence in how they use technology and how they protect it.
