Alternatives to Apollo
Other Sales engagement vendors we measure, sorted by how much they publish that Apollo does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 30 that differ from Apollo on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Apollo has 5 gaps in what we could measure: Subprocessor list, Data location stated, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116). The column “publishes and Apollo 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.
