A vCISO is your security leader — running the program, owning the strategy, briefing the board, leading the audit response. We embed at the executive level, with the seniority and accountability of a full-time CISO at a fraction of the cost.
What is a Virtual CISO?
A Virtual CISO (vCISO) is a senior security executive on a fractional basis — typically 8-20 hours per week — filling the formal Chief Information Security Officer role for organizations that need executive- level security leadership without the cost of a full-time hire.
The vCISO owns the security program: strategy, roadmap, budget, audits, incidents, vendor relationships, and board communication. The accountability is real; the engagement model is flexible.
Why a vCISO instead of a full-time hire
A full-time CISO is the right answer for many large organizations. For mid-market companies, it often isn’t — for several reasons:
- The talent is scarce and expensive — qualified CISO candidates command salaries well above $300K plus equity and bonus
- The work isn’t 40 hours/week early on — for most mid-market organizations, the actual CISO work is 10-15 hours/week of executive attention; the rest of the role is pulled into other operational work that doesn’t require a $400K leader
- The risk of the wrong hire is high — security executives have significant influence on budget, vendor selection, and organizational direction; a mismatched hire can take 6-12 months to recover from
- The market has shifted — fractional executive roles are increasingly normalized at the C-level, and customers, boards, and insurance carriers no longer treat fractional with skepticism
A vCISO solves the early-stage problem: you get senior executive leadership at the seniority your business actually needs, sized to the hours that work matches.
What a vCISO actually does
Strategic Program Leadership
We own the security strategy: where you’re investing, what you’re deprioritizing, what your three-year posture target looks like. The strategy is documented, communicated to leadership, and revisited quarterly as business context evolves.
Board and Executive Communication
We brief your board on cybersecurity posture quarterly (or as their governance schedule dictates), prepare materials suitable for non- technical audiences, and serve as the security accountability point during board discussions.
Audit and Compliance Leadership
When an audit happens (PCI, SOC 2, HIPAA, customer security review, insurance), we run point. The audit lead doesn’t have to be your CTO or your one security person — it’s the vCISO, with the seniority to manage auditor expectations and the experience to anticipate questions.
Vendor Security Review
Every significant vendor decision gets security review: the SaaS tool your team wants to adopt, the consultant who’ll have access to your network, the contractor whose code goes into production. The vCISO provides the security-decision input rather than your team rediscovering each evaluation from scratch.
Incident Leadership
When an incident happens (and statistically, one will), the vCISO leads response — coordinating internal teams, managing external communications, briefing leadership, and ensuring the post-incident work actually happens rather than getting deprioritized.
Operational Oversight
The vCISO doesn’t do hands-on operational security (that’s not what an executive does), but provides oversight and direction for the team or external vendors handling daily operations: SOC, vulnerability management, identity, etc.
Frameworks and standards we lead programs against
- NIST Cybersecurity Framework (CSF 2.0) as the typical maturity model
- ISO 27001 for organizations pursuing certification
- SOC 2 for SaaS organizations
- PCI DSS for cardholder data environments
- HIPAA for healthcare organizations
- NAIC, FFIEC, NYDFS for regulated financial services
- Industry-specific frameworks as applicable
Who this is for
- Mid-market organizations with formal security needs (regulatory, contractual, customer-driven) but no full-time CISO budget
- Pre-IPO or pre-acquisition companies needing CISO maturity for due diligence
- Companies between CISOs — interim leadership while recruiting
- Organizations with a CISO who needs senior support in specific areas (compliance, M&A integration, incident response leadership)
- Healthcare, fintech, and regulated industries where the cost of not having a CISO is higher than the cost of having one
Our methodology
Every engagement runs through the same six phases. Manual validation isn't a finishing step — it's the product.
Scope & Authorize
We define the engagement boundary precisely before testing starts — in-scope assets, out-of-bounds targets, testing windows, and emergency-stop procedures.
- Written authorization letters exchanged before any packet leaves our infrastructure
- Signal / Slack channel established for real-time findings during the engagement
- Explicit rules of engagement reviewed with legal, IT, and business stakeholders
Passive Reconnaissance
Before a single packet touches your infrastructure, we map your external footprint using public sources only — DNS, CT logs, code repos, internet-wide scan data.
- Typically discovers 15-30% more attack surface than the client originally provided
- Certificate transparency, BGP, and GitHub exposure reporting
- OSINT profile for social engineering vectors if in scope
Active Discovery
We enumerate live services across in-scope assets — ports, software versions, auth mechanisms, and protocol configurations — correlated against current vuln data.
- Hand-tuned scanning profiles — not the default Nessus run
- Protocol-level inspection for TLS, SSH, SMB, Kerberos, LDAP
- Service fingerprinting to ground truth before any exploitation
Manual Validation
Every potential issue is validated by hand before it makes the report. No CVE-dumping. No false positives. This is what separates the engagement from a scan.
- Manual exploitation attempts for any finding of High severity or above
- Business-logic testing on top of the technical layer
- Chained vulnerabilities analyzed as a single attack path
Exploitation & Impact
For confirmed vulnerabilities with attacker value, we attempt exploitation to prove impact — not just that a CVE applies, but what it gets you.
- Proof-of-exploit captured for every confirmed critical finding
- Pivot paths mapped to the actual crown-jewel data
- Interim notification inside 24 hours for anything critical
Report & Remediate
Every finding is paired with severity rated on real exploitability, reproducible proof-of-exploit, and remediation guidance your team can ship this sprint.
- Executive summary and technical deep-dive in a single report
- Findings mapped to CIS, NIST CSF, and relevant compliance families
- Retest included — we confirm the fix before we close the finding
What you walk away with
Frameworks we map to
Findings ship mapped to the control families your regulators and auditors actually check. Governance clients use these crosswalks directly in their program documentation.
- CIS Controls v8
- NIST CSF 2.0 / 800-53
- PCI DSS 4.0
- HIPAA Security Rule
- SOC 2 Type II
- OWASP ASVS
Questions we get asked
When do we need a vCISO instead of just security advisory?
When security needs an executive owner — someone with the seniority to make decisions, sign off on budgets, brief the board, and lead the response when an incident happens. Triggers we see: regulatory pressure (becoming SEC-regulated, healthcare expansion), customer pressure (enterprise customers requiring a CISO contact), board mandate, post-incident accountability, or scaling past the point where the CTO can handle security part-time.
How many hours per week is a vCISO engagement?
Typically 8-20 hours per week, depending on organizational size and program maturity. Smaller engagements (8-10 hours) work for organizations with mature operational security teams that need executive leadership. Larger engagements (15-20 hours) are typical for organizations building a security program from scratch or recovering from significant findings.
Will the vCISO be available for emergencies?
Yes. vCISO engagements include 24/7 availability for security incidents — the role isn't 'business hours only.' For active incidents, the vCISO leads response coordination and direct stakeholder communication. Outside of incidents, response time during business hours is under 4 hours; after-hours, under 24 hours unless explicitly flagged urgent.
Will the vCISO be on our org chart?
Yes — typically as 'Chief Information Security Officer' or 'Virtual CISO' depending on your preference. Some clients list the vCISO publicly on team pages and customer-facing materials; others keep the relationship internal. The vCISO has authority to act on behalf of your organization in the security domain, with explicit decision boundaries documented at engagement start.
What happens at the end of the engagement?
Most vCISO engagements run 12-24 months. Common transitions: hiring a permanent CISO (the vCISO assists the search and runs handoff), reducing to ongoing advisory retainer (lower-touch maintenance after the initial program build), or simply renewal (the relationship works, no reason to change). All artifacts and institutional knowledge transfer cleanly regardless of transition type.
