Most companies asking this question do not need a full-time CISO, but a meaningful number of them do need someone with CISO-level judgment on a fractional basis. The honest answer depends less on headcount and more on whether you are already carrying security decisions that nobody in the room is qualified to make.
What a Virtual CISO Actually Does
A virtual CISO, sometimes called a fractional CISO, is a senior security leader who works with your company part-time instead of full-time. The role is not a consultant who shows up for a project and leaves. It is ongoing ownership: building and running the security program, reviewing vendor security questionnaires before they go to prospects or land on your desk from customers, reporting risk posture to the board or leadership team, and making the calls on what gets prioritized when budget and time are both limited.
This is different from a penetration tester, an auditor, or a compliance consultant who helps you pass a specific control set. A vCISO sits above those engagements and decides which ones you need in the first place, then holds the program together between them. If you want the full scope of what this looks like at traztech, see our fractional CISO service.
The Signal That You Genuinely Need One
The clearest signal is not company size, it is decision ownership. If a customer's security questionnaire lands on your desk and you are guessing at answers, if your board asks about cyber risk and you have no structured way to answer, or if you are trying to close a SOC 2 or ISO 27001 audit without anyone senior enough to make architecture and policy tradeoffs, you already need this function. You may not need it five days a week, but you need it.
Companies in this position tend to share a few traits:
- You are selling into regulated or security-conscious buyers (fintech, healthtech, enterprise SaaS) and questionnaires are becoming a bottleneck in your sales cycle.
- You have raised a round or are approaching one, and investors or acquirers are starting to ask about your security posture during diligence.
- Your engineering team is capable but has no one with the authority or bandwidth to own risk decisions across the whole business, not just the codebase.
- You are pursuing SOC 2, ISO 27001, or preparing for CPCSC as a Canadian federal supplier and need someone who has run an audit before, not someone learning on your dime.
If two or more of these describe you, a fractional CISO is not a luxury purchase, it is closing a real gap.
Who Is Over-Buying
Not every early-stage company needs this yet, and it is worth saying so plainly. If you are pre-revenue, have no customer data of consequence, and nobody is asking you security questions in a sales process, hiring a vCISO before you have a product-market fit problem to solve is premature. The same is true if what you actually need is a single deliverable, a penetration test report, a specific policy document, or a one-time risk assessment, rather than ongoing program ownership. Buying a retained CISO relationship to get one artifact is expensive and unnecessary; a scoped engagement solves that more cheaply.
Some companies also buy a vCISO because it sounds like the responsible thing to do, without a clear question they are trying to answer. That is a sign to start smaller: a gap assessment or a readiness review against a specific framework will usually surface whether ongoing leadership is actually needed, before you commit to a retainer.
Fractional vs. Full-Time: The Real Tradeoff
A full-time CISO makes sense once security decisions are happening daily, across a large enough team, that part-time attention creates real lag. That threshold is usually well past 100 employees with a dedicated security or IT function underneath the CISO. Below that, a full-time hire is frequently underused, expensive, and hard to retain because the role gets bored or the company cannot justify the salary against the actual volume of decisions.
A fractional CISO gives you the same seniority and the same accountability structure, board reporting, questionnaire ownership, audit liaison, at a cost and cadence matched to how often those decisions actually arise. It also solves a hiring problem specific to security: qualified CISOs are scarce and expensive, and a company with 40 employees is rarely their first choice of employer. Fractional arrangements let smaller and mid-market companies access that level of expertise without competing for a full-time hire they cannot realistically win.
What Good Virtual CISO Support Looks Like Day to Day
In practice, the value shows up in unglamorous, recurring work rather than one dramatic intervention. Expect a vCISO to maintain your risk register, turn security questionnaires around on a sales team's timeline instead of weeks later, run quarterly reporting that a board actually finds useful, and act as the technical liaison during an audit so your engineers are not pulled off product work to answer auditor emails. The person doing this should also have hands-on technical credibility, not just governance experience, so they can evaluate whether a proposed control actually reduces risk or just produces paperwork.
At traztech, this work is led by Jacob Masse, a published security researcher with six CVEs to his name, including CVE-2024-45163, a critical (CVSS 9.1) kill-switch vulnerability affecting Mirai-based botnets. That background matters for vCISO work specifically because it means technical judgment calls, not just compliance checklists, are grounded in real vulnerability research rather than a framework template.
The Canadian Context Changes the Calculation
Canadian companies face a slightly different set of pressures than their US counterparts, and it affects when a vCISO becomes worth it. PIPEDA sets the federal baseline for privacy obligations, Quebec's Law 25 adds stricter requirements for any company handling Quebec residents' data, and companies selling to the federal government increasingly need to navigate the Canadian Program for Cyber Security Certification (CPCSC). None of these are optional add-ons once they apply to you, and a company juggling US customer SOC 2 demands alongside Canadian privacy law obligations is exactly the profile that benefits from someone who owns the whole picture rather than treating each requirement as a separate fire drill.
We work with growing tech companies across Toronto, Waterloo, Ottawa, Vancouver, Calgary, and Montreal, and the pattern is consistent: Canadian buyers moving up-market into US enterprise and mid-market accounts hit the SOC 2 and security questionnaire wall earlier than they expect, often while still building out their first real security hire. A fractional CISO bridges exactly that gap, in both directions, satisfying US buyer expectations while keeping the Canadian regulatory obligations from falling through the cracks.
How to Decide, Practically
Start by counting how many security-relevant decisions cross your desk in a typical month that you are not confident you are making correctly. If it is a handful and getting worse, and especially if a specific deal, audit, or funding round is forcing the question, a fractional CISO is the right-sized answer. If you cannot name a decision that is currently going unmade, hold off and revisit the question when a customer questionnaire or a compliance deadline forces it. Companies preparing for SOC 2, ISO 27001, or CPCSC specifically should read our overview of compliance program support alongside the fractional CISO service, since the two are usually bought together.
If you are unsure which category you fall into, that ambiguity is itself worth a conversation rather than a guess. Contact traztech for a straightforward assessment of whether fractional CISO support fits where your company actually is, not where a vendor wants you to think you are.
