# Timeout threshold

A timeout determines the execution threshold of a scan from running long scans. For example, any scan running longer than the set time period results in a failure.

If the scan or the check takes longer than the set time period set by the quota rule, an error message appears.

**Note:** By default the scans are limited to three hours and individual checks are limited to 10 minutes.
