Alternatives to Solaris
Other Payment orchestration vendors we measure, sorted by how much they publish that Solaris does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 30 that differ from Solaris on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Solaris has 8 gaps in what we could measure: Data processing agreement, Subprocessor list, Public pricing, Certifications named, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “publishes and Solaris 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.
