Research methodology

Sources we use

• Vendor product documentation, changelogs and published pricing pages.
• Published standards and framework material where a security or compliance claim is involved.
• Hands-on configuration of the product where a free tier, trial or self-hosted build is available to us.
• Named public reporting and primary data, cited so readers can verify it themselves.

How comparisons are built

Comparison sections use criteria that are defined before the products are ranked, and the same criteria are applied to every product in the set. Pricing is recorded with the tier it belongs to, because per-seat and usage pricing shift constantly. When a price or limit cannot be confirmed on the vendor's own published material, we say so instead of estimating.

What we will not claim

We do not invent statistics, benchmarks, testimonials, certifications, review scores, user counts or test results. We do not present a vendor's marketing claim as a verified outcome. If we have not tested something, the article says we have not tested it. Where a topic requires professional advice — medical, legal, tax, insurance — we decline the topic rather than approximate an expert.

Currency and updates

Software changes fast. Each article shows its published date and, where it has been revised, its updated date. When a vendor changes pricing, packaging or a capability we relied on, we revise the existing article instead of publishing a second version of it.

Limits of this methodology

Our reviews are documentation-led and configuration-led, not lab-benchmarked. We do not run long-horizon reliability testing, and we do not have access to enterprise tiers of every product we cover. Read our guides as a well-researched starting point for your own evaluation, not as a substitute for a trial in your own environment.
