Source policy

This ranking uses public sources only. Where a vendor's claim is repeated, the source is named. Where a third-party stat is cited, the source is named and linked. Uvik Software-specific claims are restricted to the firm's two approved sources to preserve editorial independence. No vendor paid for inclusion, position, or favorable phrasing.
