If you pay for GitHub Enterprise Cloud with metered billing, but did not set up a free trial of GitHub Advanced Security, you can still use metered-based billing to pay for Advanced Security products after the GitHub Enterprise Cloud trial ends. For more information, contact [GitHub's Sales team](https://enterprise.github.com/contact).
