How we list vendors

  • A product is listed because it provides the control. Nobody pays to be listed, and on story pages the examples rotate, so no vendor is always first.
  • Vendor pages show both the vendor's own research and the incidents involving its products, from our own coverage. We do not leave either out.
  • Our summaries are written by us, based on the vendors' own pages. Text in quotation marks or marked "in their own words" is the vendor's own, quoted from its website.
  • Logos, product names and quoted text belong to the vendors and are shown to identify them.
  • Something wrong? Use "Suggest a correction" on the vendor's page. A product we should look at? Email support@threatnoir.com.
