vCISO Lite Launches Quantitative Cyber Diligence — Dollar-Denominated Cyber Cost of Deal for M&A, PE, and Investment Committees, Delivered in 72 Hours

ATLANTA — May 29, 2026 — vCISO Lite today launched Quantitative Cyber Diligence (QCD), a dedicated diligence product for M&A deal teams, private equity operating partners, and investment committees. QCD replaces the forty-page cyber-diligence questionnaire and the three-week Big-4 engagement with a five-pillar, dollar-denominated Cyber Cost of Deal (CCOD)figure — delivered in 72 hours, defensible at the IC, and comparable across a portfolio. The product is live at diligence.vcisolite.com.

The launch answers a pattern deal teams already know well. FTI Consulting’s 2026 M&A and Cybersecurityreport found that 42% of deals encountering a cyber incident during or after close lose value, 69% of executives say a post-transaction cyber incident negatively impacted the deal, and 84% of organizations can’t align cybersecurity policies after the transaction closes. Westbourne Research (2025) put 21% of deals as delayed, repriced, or abandoned over cybersecurity issues surfaced in diligence — the Verizon acquisition of Yahoo cut its price by $350 million on undisclosed breach exposure alone. The signal is priced-in on every deal. The method for pricing it is not.

“Cyber is the only line item on the diligence checklist that still gets scored red-yellow-green,” said Yolonda Smith, founder of vCISO Lite. “Financial diligence has a methodology. Legal diligence has a methodology. Cyber diligence has a forty-page questionnaire and three weeks of Slack threads. That’s not diligence — that’s hope. QCD gives deal teams what they already have for every other risk on the deal: a number, sourced to specific inputs, defensible against a real audience, and comparable across the portfolio.”

What’s in the release

The QCD product is live today for M&A buyers, PE operating partners, corporate development teams, and founders preparing to be diligenced. In the initial release, deal teams can commission the following on any active engagement:

• Tier 1 External Snapshot — delivered in 48 hours. Attack Surface & Exposure pillar only, no target-side participation required. Designed for the LOI stage. Published at $12,500 flat.
• Tier 2 Full QCD — delivered in 72 hours. Board-ready report covering all five pillars, per-pillar driver analysis, three-scenario CCOD (best / expected / worst), 90-day remediation budget, and a valuation-adjustment recommendation. Priced against target enterprise value, starting at $15,000.
• Founder-side preparation.The same methodology run against your own posture, packaged as a shareable diligence artifact you can hand to a prospective buyer at deal start — eliminating the three-week back-and-forth on cyber.
• Portfolio rollup + IC briefing generator.Cross- engagement portfolio dashboard, drift attribution across CCOD components, and a one-click IC briefing PDF for the operating partner’s next investment committee.
• Ephemeral-then-portable delivery.Raw target data lives only for the engagement window; every close event produces a JWS-signed deletion certificate. If the deal closes, analysis artifacts port into the operating company’s vCISO Lite tenant as its Year-0 baseline. Detail in “The Year-Zero Cyber Baseline”.

The five pillars of the CCOD

QCD decomposes cyber risk into five defensible line items, each producing a dollar-denominated score summed with correlation adjustment into a single CCOD figure expressed in dollars and as a percentage of enterprise value:

• Attack Surface & Exposure— probability- weighted expected annual loss from the target’s current external attack surface: unpatched exposures, misconfigured cloud resources, leaked credentials, dormant services. Measured by direct observation, no target cooperation required. Typical range $50K–$5M.
• Third-Party & Vendor Concentration— dollar impact if a critical vendor compromises or fails. Combines maximum single-vendor loss with an aggregate concentration index. Typical range $100K–$25M.
• Data Sensitivity & Regulatory Exposure— probable maximum loss from a reportable breach, incorporating data classification, jurisdictional coverage (GDPR, CCPA/CPRA, HIPAA, GLBA, PCI DSS, state laws), and breach-notification obligations. Typical range $500K–$50M+.
• Security Program Maturity— cost to bring the target’s program to industry-peer parity, benchmarked against sector- and stage-matched companies using vCISO Lite’s cross-customer posture data. Typical range $150K–$3M.
• Integration & Post-Close Risk— 90-day remediation budget and go-live value at risk during identity merges, vendor consolidation, and detection-coverage stitching. Typical range $200K–$10M.

A worked example — how the five pillars sum on a realistic mid-market target — is available in “Inside a Cyber Cost of Deal: A Worked Example for Investment Committee”. The 72-hour engagement shape — from LOI-stage engagement creation to IC-ready deliverable — is walked step-by-step in “The Private Equity Buyer’s Playbook for Cyber Due Diligence: From LOI to IC in 72 Hours”.

What grounds the methodology

QCD’s pillar math sits on established loss-quantification and risk-assessment standards, adapted to the transaction-diligence context:

• Factor Analysis of Information Risk (FAIR)— The Open Group’s open standard for loss-event frequency × loss-magnitude decomposition. Pillar 1 and Pillar 3 use FAIR-shaped math over observable inputs.
• NIST SP 800-30 Rev. 1— the U.S. federal guide for conducting information-security risk assessments, including threat-source and adverse-event modeling. Provides the risk-assessment scaffolding around the pillar decomposition.
• ISO/IEC 27005:2022— the international standard for information security risk management, referenced for risk-treatment decisions and the escrow / reprice / walk recommendation tier.
• SEC cybersecurity disclosure rule (Item 106 of Regulation S-K; Item 1.05 of Form 8-K)— effective December 2023. Makes cyber material to public-company reporting and to any deal that will surface a covered issuer — and gives the acquirer a defined obligation to know what they are buying.

The complete methodology, including per-pillar rubrics, correlation adjustment, and the tiered recommendation surface (proceed → escrow → reprice → walk), is published in the QCD executive brief and the QCD academic paper (v0.6, May 2026), available at vcisolite.com/briefs-and-specs. A book-length treatment — Someone Else’s Debt (Smith, 2026) — is available on Amazon and Kindle.

How the number changes the deal

The CCOD is not a report you read and file. It plugs into the valuation model as a dollar line item and into the deal-terms conversation as an escrow amount, a reps-and-warranties trigger, or a price adjustment. When the Q90 outcome or a single pillar breaches deal-team thresholds, the platform surfaces mechanical recommendations (proceed, escrow, reprice, walk) with the supporting math attached. vCISO Lite’s guidance on using the number at the negotiating table — specifically how to choose between rep-and-warranty insurance and a straight price cut — is at “R&W Insurance or Price Reduction?”.

For deal teams that want end-to-end QCD engagements run by AI agents, with cryptographic proof of every action the agent takes, vCISO Lite’s Trustworthy Autonomy™layer covers M&A cyber diligence in its public-beta program alongside TPRM, audit preparation, and KRI monitoring.

Availability

Quantitative Cyber Diligence is generally available today at diligence.vcisolite.com, priced per engagement rather than by subscription: Tier 1 External Snapshot at $12,500 flat (48-hour delivery), and Tier 2 Full QCD priced against target enterprise value with a $15,000 floor (72-hour delivery). A companion product experience for operating-company teams — running QCD on their own posture ahead of an anticipated deal, or on a target inside the vCISO Lite Ultra subscription — is at vcisolite.com/diligence. The QCD executive brief and academic paper, plus companion briefs on DC-TPIR, Continuous Maturity Assessment, and Trustworthy Autonomy, are at vcisolite.com/briefs-and-specs. Editorial coverage lives in the M&A Security Diligence series and the Someone Else’s Breach series. The published product changelog for the QCD launch is at vcisolite.com/changelog/qcd-book.
