Principles
- Say only what we can source. Every price, percentage and product claim links to where it came from.
- Say what we did not do. We do not describe desk research as testing.
- Keep claims and evidence apart. A vendor's number is labeled as the vendor's number.
- Answer first. Each page opens with the conclusion, then shows the reasoning.
- Write plainly. If a sentence needs jargon, we define it.
Sourcing
We prefer primary sources: pricing pages, documentation, legal terms, regulatory texts and named-customer case studies. We use independent press, analyst and procurement data to test vendor claims. A vendor's content is never used as evidence about a competitor. Each source shows the date we last read it. The full method is on How we review.
Independence
Rankings are produced by a published rubric and cannot be bought. We do not accept payment for placement, do not publish sponsored reviews and do not use affiliate links. If the publisher's own product appears, it is labeled and scored by the same rules, and we expect readers to weigh that disclosure for themselves.
Language editions
The site is published in US English, UK English, German and Spanish. All editions are generated from the same product database, so prices, scores and rankings are identical in every language. Each edition adds guidance specific to its market, such as the law that applies and whether a product documents support for the local language. Prices stay in the currency the vendor publishes.
Use of AI
We use AI tools to research and draft pages from cited sources, and we say so on every page. AI-drafted text is held to the same sourcing rules as anything else: no source, no claim.
Legal information is not legal advice
Our guides describe laws and regulator guidance in plain language and link to the official texts. They are general information, not legal advice, and rules change. Check your own obligations with a qualified adviser.
Corrections
We correct confirmed errors promptly, in the product database where that applies, and record material corrections in the changelog. Vendors are welcome to send corrections with a link to a public source; we do not change scores on the basis of private assurances.
This page was researched and drafted with AI assistance from the sources listed on it. We have not run hands-on tests of these products. Method: How we review
