The method, sources, cadence, and named author behind every price stamp on this directory. Short, deliberately not a sprawling /methodology page.

How does this site verify vulnerability scanner pricing?

Per-row pricing is verified against the vendor's own product page on the date stamped per row. Quote-only vendors carry partner-reported ranges drawn from named analyst sources, never inferred rates. Re-verification cadence: per-vendor pages monthly, the pricing cheatsheet quarterly, and KEV / NVD counters weekly. Named author: Oliver Wakefield-Smith, Digital Signet.

The four rules

  1. 01 Every numeric claim is sourced to a primary source URL (vendor pricing page, CISA KEV JSON, NIST NVD, PCI SSC list, FedRAMP Marketplace).
  2. 02 Quote-only vendors get a partner-reported range with a named secondary source. Never an inferred per-asset rate.
  3. 03 Where data isn't published, the page says so explicitly. No filler numbers.
  4. 04 Re-verification cadence is published per row. Per-vendor pages monthly; pricing cheatsheet quarterly; KEV / NVD counters weekly.

Vendor correction process

If you represent a vendor and want a price corrected, email oliver@digitalsignet.com with the public URL and the corrected figure. Corrections logged on the changelog page within seven days.

FAQ

  • Are these affiliate links?
    No. Outbound links to vendor pricing pages are nofollow non-affiliate. No vendor pays for placement or ranking.
  • How often is pricing re-verified?
    Per-vendor pages monthly. Pricing cheatsheet quarterly. KEV / NVD counters weekly.
  • Why are quote-only vendors not given inferred rates?
    Inferring a per-asset rate for a vendor that does not publish one is a fabrication. We cite partner-reported ranges or decline to quote.
  • What if a vendor disagrees with a price?
    Email oliver@digitalsignet.com with the public URL and corrected figure. Corrections logged on /changelog within seven days.
