Rate limiting rulesets
A rate limiting rule defines a rate limit for requests matching an expression, and the action to perform when that rate limit is reached. At the account level, rate limiting rules are always grouped into rate limiting rulesets, which you then deploy.
To apply a rate limiting ruleset at the account level, create a custom rate limiting ruleset with one or more rate limiting rules and then deploy it to one or more zones on an Enterprise plan.
