How We Verify Prompt-Injection Vendor Pricing

Plain-text description of how pricing is collected, verified and dated. Vendor source URLs and the verified-on date are published on every page.

Collection

  • Vendor pricing pages, captured verbatim with URL and date.
  • Vendor sales calls, only on the record, only if the rep confirms a number we can publish.
  • Public references (court filings, S-1s, partner pages) for context only.
  • OWASP genai.owasp.org for the LLM Top 10 attack taxonomy.

What we will not do

  • Infer a number for a quote-only vendor.
  • Cite an industry average that is not anchored to a named published dataset.
  • Carry a price past its verified-on date without re-pulling.
  • Accept a vendor-supplied composite without a published primary source.

Sources we cite explicitly

  • Every vendor pricing page URL is on the relevant vendor page.
  • OWASP Top 10 for LLM Applications 2025 at genai.owasp.org.
  • NIST AI 100-1 (AI RMF) and NIST AI 600-1 (Generative AI Profile).
  • Regulation (EU) 2024/1689 (the EU AI Act).
