A virtual or fractional CISO usually costs an estimated $3,000 to $20,000 per month on retainer. Hands-on mid-market engagements cluster around $5,000 to $12,000 per month. Published provider guides place hourly work around $200 to $500 and defined projects around $5,000 to $50,000 or more.
Every band on this page is an editorial estimate synthesized from public provider sources. It is not a firm-confirmed quote. The number becomes useful only when the proposal states who does the work, what they own, how much time is included, and whether one-time program build work sits inside or outside the retainer.
How much does a vCISO cost per month?
Our source synthesis estimates vCISO retainers at $3,000–$20,000 per month. Hands-on mid-market programs cluster around $5,000–$12,000 monthly. These are market estimates, not firm-confirmed quotes; scope and practitioner involvement determine the proposal.
vCISO Pricing Index by engagement model
| Engagement model | Estimated price | Best fit | Evidence status |
|---|---|---|---|
| Monthly retainer | $3,000–$20,000/month | Ongoing leadership and program ownership | Estimate synthesized from five public source groups |
| Mid-market retainer | $5,000–$12,000/month | Hands-on strategy plus selective execution | Estimate, strongest cross-source cluster |
| Hourly advisory | $200–$500/hour | Narrow reviews, board prep, or specialist advice | Estimate from published provider guides |
| Fixed project | $5,000–$50,000+ | Risk assessment, program build, or audit-readiness sprint | Estimate; deliverables vary substantially |
Retainer scope explains most of the spread. A light engagement may cover a monthly leadership meeting, roadmap review, and limited advisory access. A hands-on engagement may add control ownership, policy work, evidence cadence, vendor reviews, board reporting, and incident-response leadership.
Estimated retainer by company size and scope
| Company profile | Typical scope | Estimated monthly band |
|---|---|---|
| Startup or small business | One framework, advisory support, internal team executes | $3,000–$5,000 |
| Growing company | Program leadership, SOC 2 readiness, customer security support | $5,000–$9,000 |
| Mid-market | Hands-on program management, board reporting, several workstreams | $5,000–$12,000 |
| Upper mid-market or regulated | Multiple frameworks, complex environment, deeper availability | $12,000–$20,000+ |
Company size is a proxy, not a billing formula. A small regulated company with weak controls can require more work than a larger SaaS company with a mature security team. Ask providers to map price to deliverables rather than headcount alone.
How much does a vCISO charge per hour?
Published provider guides place vCISO hourly work at an estimated $200–$500 per hour. Hourly billing fits narrow advisory or review work better than ongoing program ownership, where a monthly retainer makes responsibility and availability clearer.
Hourly work can make sense for an architecture review, incident-response plan, board briefing, policy review, or a second opinion on a roadmap. It is harder to manage when the vCISO must own a program across several months. A capped block can also leave unclear who acts when evidence fails or a customer questionnaire arrives.
Compare hourly proposals on the named practitioner, minimum block, response time, unused-hour treatment, and deliverable. A lower rate is not cheaper if junior staff need more time or the engagement ends with advice your team cannot implement.
What drives the price up or down?
Price rises with hands-on implementation, company and system complexity, regulated industries, multiple frameworks, incident-response availability, and senior-practitioner time. Advisory-only work, a mature internal team, one framework, and a narrow meeting cadence usually lower the quote.
| Price driver | Lower-cost scope | Higher-cost scope |
|---|---|---|
| Delivery | Advice and review | Provider builds and operates the program |
| Frameworks | One framework | SOC 2 plus ISO 27001, HIPAA, CMMC, or others |
| Environment | Standard cloud stack | Many entities, systems, regions, or legacy platforms |
| Access | Scheduled meetings | On-call incident and customer support |
| Staffing | Pooled delivery team | Named senior practitioner with continuity |
| Program stage | Mature controls | Greenfield risk, policy, and control build |
Require the proposal to name exclusions. Penetration testing, compliance software, legal review, managed detection, and the independent SOC 2 audit may sit outside the vCISO fee. If two proposals bundle different services, normalize them before deciding which costs less.
How does vCISO cost compare with a full-time CISO salary?
A $5,000–$12,000 monthly mid-market vCISO estimate equals $60,000–$144,000 annually. Cynomi’s published comparison places full-time North American CISO base salary around $240,000–$350,000 before additional compensation, making fractional leadership materially cheaper but also part-time.
The comparison is not role-for-role. A full-time CISO works inside one company every day, manages staff directly, and carries broader executive duties. A vCISO divides time across clients and should have a defined availability model. Fractional economics work when the company needs senior ownership but does not yet have a full-time executive workload.
Budget from annualized contract cost, not the monthly headline. Add one-time setup, travel, tools, projects, and internal implementation time. Then compare that total with salary, benefits, equity, recruiting, and the team a full-time hire would still need.
Is a vCISO worth it for a startup?
A vCISO can be worth it when a startup needs one accountable security leader across SOC 2 readiness, customer reviews, and ongoing controls but cannot justify a full-time CISO. A fixed readiness project is leaner when internal staff can own execution.
The decision turns on ownership. If an engineering or operations leader can implement remediation and maintain evidence, buy a defined readiness project or narrow advisory help. If nobody owns security after the initial push, a retainer can protect the cadence through customer reviews and the Type 2 observation period.
Use the vCISO firms directory to compare providers, then ask every finalist for the same three views: one-time build cost, steady-state monthly retainer, and first-year total. Keep the independent CPA audit on its own line because the vCISO prepares the program but does not issue the SOC 2 report.
How did we build the vCISO Pricing Index?
We synthesized public pricing and market-range pages from five source groups named in the strategy research, then used overlapping bands rather than the highest or lowest claim. Provider-published figures are observations from their own market view, not independent or firm-confirmed industry statistics.
The source set was retrieved on 2026-07-12:
| Source | Published signal used |
|---|---|
| vCISO.com | $5,000 published retainer and a $3,000–$15,000 provider-stated market band |
| Compass IT Compliance | $2,000–$20,000+ retainer, $5,000–$9,000 mid-market cluster, $200–$300+ hourly |
| Workstreet | $3,000–$20,000 retainer, $200–$400+ hourly, $5,000–$50,000+ project |
| Cynomi | $2,600–$20,000 retainer, $200–$300 hourly, $5,000–$50,000+ project |
| SideChannel and Atlant Security | SideChannel: $3,000–$20,000 overall and $3,000–$12,000 for most mid-market companies; Atlant: $3,000–$15,000 retainer, $200–$500 hourly, and $5,000–$50,000+ project |
We publish the broad $3,000–$20,000 retainer estimate because it is the stable overlap across the set, and the narrower $5,000–$12,000 mid-market band because several sources cluster there. We round bands to avoid false precision and review the index quarterly. Future firm-submitted prices will remain labeled separately from editorial estimates.
