A company is implementing security and compliance by using AWS Trusted Advisor.

The number of AWS Trusted Advisor checks available to an account depends on the AWS Support plan associated with the account. The Basic and Developer support plans provide access to a limited set of Trusted Advisor checks, primarily focused on security and service limits.

The Business and Enterprise support plans provide full access to all Trusted Advisor checks, including cost optimization, performance, fault tolerance, and security categories.

Running EC2 instances, SCPs, or MFA settings do not affect the availability of Trusted Advisor checks.

Therefore, the AWS Support plan determines the quantity of available Trusted Advisor checks.
