SaaS Ranking

Vendors whose SLA page tops out at 99.99 %

29 of the 8221 vendors where we could measure this at all, that is 0.4 %. Below is every one of them with the sentence we read it from.

Last change recorded in these rows: 2026-09-18. We compare every new measurement with the one before it; one that finds the same thing is not a change.

This is what they publish, not what we verified. We found this wording on the page linked in each row on the date given. It says nothing about vendors that are not on this list: they may publish the same thing somewhere we did not look, or behind a login. How we look for this.

Most common in: Cloud hosting (5), Password and identity (3), Privileged access management (3), Feature flags and experimentation (2), Accounting (1), API security (1), Business continuity (1), CRM (1).
