What a record is
Each record is one buying decision by one organization. A purchase can produce many documents (a request for proposal, amendments, an evaluation, an award and a contract), and we keep them together as one decision with several sources, rather than counting them as several purchases.
Where evidence comes from
- Firsthand accounts from people involved in the decision.
- Procurement documents: requests for proposal, evaluations, award notices and contracts.
- Independent tests published by testing organizations.
- Vendor documentation, used for what a product officially supports.
- Vendor-published customer stories, which record what a customer says happened. They are labeled and never treated as independent proof that a product is better.
Context, not generalization
Our readers are mostly U.S. private companies, but some of the best-documented purchases come from public bodies and from other countries. Every record shows its organization type and country, for example "Public sector · United Kingdom", so you can judge how well it applies to you.
How well supported is a record?
Each record carries an editorial rating (well supported, partly supported, thinly supported, or not yet reviewed) describing how well its sources support what we've recorded. A person on our team makes this judgment. It is never assigned automatically or by AI, and it is separate from the type of source and from whether a vendor published it.
Pricing
We record what a price included (software, managed service, implementation, incident response and other items) and whether the scope is clear enough to compare. We never divide a bundled contract by its endpoint count and call the result a license price.
Unknown means unknown
If a source doesn't state something, we show "Not disclosed." We don't estimate, infer or fill gaps.
Names
We name an organization when a public source identifies it and there's no reason to withhold it. Otherwise we use a description such as "Regional manufacturer, about 1,200 endpoints."
Corrections
When better evidence becomes available, we update the record and the page's last-reviewed date.
