Alternatives to Square
Other Payment processing vendors we measure, sorted by how much they publish that Square does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 26 that differ from Square on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Square has 6 gaps in what we could measure: Data processing agreement, Subprocessor list, Status page with history, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116). The column “publishes and Square does not” is the one that closes them.

Only criteria we could measure for both are counted. Where we could measure one and not the other, the row is silent: that would be a statement about our measurement, not about either vendor. Every single result with its source is on the two profiles.
