MDR / MSSP No sufficiently comparable public US price range verified Sources, quantities, response rights, retention, minimums, incident scope Request like-for-like written quotes
vCISO Modular service descriptions found, but no validated representative fee range Named lead, hours, availability, outputs and implementation Quote a defined quarter or statement of work
Penetration test Verified service categories, but no representative price distribution Targets, roles, manual effort, safety constraints and retest Use one scope and rules-of-engagement template
Incident response / recovery Advertised service categories found Retainer terms, activation, included hours, emergency and recovery charges Request precise retainer and additional-work terms

Source for the numeric software price: Microsoft's US product page. Category examples: vCISO, testing and cyber/incident services. Marketing pages establish offerings, not comparable transaction prices.

The unverified ranges in the supplied context are not reproduced as benchmarks. They lacked a reproducible sample, comparable scope and dated primary price evidence. Repeating them with a vague “estimate” label would not repair that gap.

Illustrative arithmetic: 200 eligible users × $3 × 12 months = $7,200 annual software subscription before applicable additional costs. This is not an MDR quote and must not be extrapolated past the product's user limit.

For a service comparison, use:

Year-one total = recurring fees + required incremental licenses + setup/migration + usage charges + scoped optional work + internal labor + applicable taxes.

For three years, calculate each year separately and add one-time transition/exit costs where applicable. Model contractual uplifts only where known. Otherwise show scenarios with explicit buyer-selected assumptions.
