vCISO vs Full-Time CISO: The Real Cost Comparison for Irish SMEs

A cybersecurity recruiter recently told us that the average time to fill a CISO position in Ireland is now 14 months. The average salary? North of €120,000 — before benefits, pension, and the inevitable training budget. For an Irish SME with 20 to 200 employees, that number is not just expensive. It is unrealistic.

Note: Where specific business scenarios are described in this article, they are illustrative examples based on composite real-world incidents. Details have been anonymised to protect confidentiality.

But the need for senior security leadership is real. NIS2 is here. Cyber insurers are demanding evidence of governance. Enterprise clients are asking pointed questions about your security programme before signing contracts. The question is not whether you need a CISO — it is whether you need a full-time one.

This article breaks down the real costs, the real deliverables, and the honest trade-offs between hiring a full-time Chief Information Security Officer and engaging a virtual CISO (vCISO) on a fractional basis.

What Does a Full-Time CISO Actually Cost?

The salary is only the beginning. Here is what a full-time CISO hire actually costs an Irish SME when you account for the total employment package:

That is €13,500 to €22,700 per month — for a single hire. And you still need to find someone willing to relocate to or work from Donegal, Galway, or wherever your business is based. The talent pool for senior security professionals in Ireland outside Dublin is extremely thin.

The hidden cost nobody mentions: if your CISO leaves after 18 months — which is below the industry average tenure of 26 months according to Heidrick & Struggles — you are back to square one. Another 14-month recruitment cycle, another recruitment fee, another six months before the new hire understands your business.

What Does a vCISO Cost?

A virtual CISO provides the same strategic security leadership on a fractional basis. At Pragmatic Security, our vCISO engagements are structured as follows:

Annual cost range: €18,000–€72,000 — compared to €162,000–€272,000 for a full-time hire. That is a saving of between €90,000 and €254,000 per year.

But cost alone is not the point. The question is: what do you actually get?

What Each Option Delivers

Here is an honest comparison of what a full-time CISO and a vCISO deliver across the areas that matter most to an Irish SME:

Strategic Security Leadership

Full-time CISO: Dedicated, always available, deeply embedded in your business culture. Attends every meeting, knows every employee, understands every system. This depth is genuinely valuable — if your organisation is large enough to need it daily.

vCISO: Brings the same strategic capability but on a scheduled basis. Monthly board reports, quarterly risk reviews, annual strategy updates. For most SMEs, security leadership is needed in concentrated bursts — not eight hours a day.

Verdict: For businesses under 250 employees, a vCISO provides sufficient strategic coverage. Above 500 employees, a full-time CISO starts to make sense.

Regulatory Compliance

Full-time CISO: Can dedicate sustained attention to compliance programmes. Useful during major regulatory transitions (NIS2 transposition, for example).

vCISO: Typically has broader regulatory experience across multiple clients and sectors. Has seen how different businesses interpret the same regulation. This cross-pollination of experience is a genuine advantage.

Verdict: A vCISO's breadth of experience across multiple clients often outweighs a full-time CISO's depth in a single organisation — especially for compliance.

Incident Response

Full-time CISO: On-site immediately. Knows every system, every contact, every vendor relationship. In a genuine crisis, having someone physically present who knows the business is invaluable.

vCISO: Available by phone and remote access. May not know every system intimately. However, a good vCISO has handled incidents across multiple organisations and brings pattern recognition that a CISO in their first incident does not have.

Verdict: Slight edge to full-time for the first 4 hours of a major incident. After that, experience matters more than proximity — and a vCISO who has managed 15 incidents will outperform a CISO managing their first.

Vendor & Tool Evaluation

Full-time CISO: May have limited exposure to the market. Tends to recommend tools they have used before. May develop vendor relationships that create bias.

vCISO: Sees dozens of tools across multiple clients. Knows which vendors oversell, which products are genuinely useful for SMEs, and which are enterprise tools dressed up for the mid-market. No commissions, no vendor relationships.

Verdict: Clear advantage to a vCISO for unbiased vendor guidance.

The Real Decision Framework

Stop thinking about "vCISO vs full-time CISO" as an either/or decision. Instead, ask these five questions:

1. How many hours per week does my business actually need senior security leadership?

If the answer is under 20 hours, a vCISO is the right choice. Most Irish SMEs with 20–200 employees need 8–16 hours per month of senior security input — not 160 hours.

2. Can I attract and retain a senior security professional?

If your business is outside Dublin, the honest answer is probably no. The ICS2 Cybersecurity Workforce Study consistently shows that Ireland has a cybersecurity skills shortage of over 15,000 professionals. Senior talent gravitates to financial services, big tech, and consulting firms.

3. What happens if my CISO leaves?

With a full-time hire, you lose institutional knowledge and face a 14-month recruitment gap. With a vCISO provider, continuity is built into the service — documentation, processes, and relationships are maintained by the firm, not a single individual.

4. Do I need someone who has seen this problem before?

A vCISO working across 8–12 clients sees more security scenarios in a year than a full-time CISO sees in five. If your business is facing a new challenge — NIS2 compliance, a cyber insurance application, a supply chain audit — a vCISO has almost certainly handled it before.

5. What is my actual budget?

If you can genuinely afford €160,000+ per year for a security hire and your organisation has 300+ employees, a full-time CISO may be the right investment. For everyone else, a vCISO delivers 80–90% of the value at 20–30% of the cost.

What Irish SMEs Are Actually Doing

Based on our experience working with businesses across Ireland, here is the pattern we see:

• 10–50 employees: No dedicated security leadership. IT is handled by a managed service provider or an internal IT generalist. Security is an afterthought. This is the highest-risk group — and where a vCISO at the Advisory level (€1,500/month) delivers the most dramatic improvement.

• 50–150 employees: May have an IT manager but no security specialist. Starting to face compliance pressure from clients and insurers. The sweet spot for a Standard vCISO engagement (€2,500–€4,000/month).

• 150–500 employees: Often has an IT team of 3–8 people but no CISO. Facing NIS2 obligations, enterprise client audits, and board-level questions about cyber risk. Comprehensive vCISO or part-time embedded CISO is the right model.

• 500+ employees: Likely needs a full-time CISO — but even then, many organisations use a vCISO to bridge the gap during recruitment or to provide specialist expertise alongside their internal team.
