Sources

This page lists every public page used to build the ranking, grouped by company in rank order. Each entry carries the date it was checked. Facts shown elsewhere on the site link back to one of these pages.

Types of sources

• Company websites: service pages, office addresses, careers pages, case studies, security and privacy pages. Case studies and client outcomes from these pages are marked "vendor-published".
• Review platforms: Clutch, G2 and GoodFirms profiles, for review counts, ratings, reviewer locations and published rate bands.
• Certification records: registry entries or certificates for ISO, SOC and CMMI claims. Where no registry entry was found, the claim is attributed to the company.
• Press releases and filings: for founding dates, acquisitions, name changes and legal entities.

Material shared privately by a company is not used. When a public page contradicts another, the company's own current page is used and the difference is noted in the data.
