GitHub has many features that help you improve and maintain the quality of your code. Some of these are included in all plans, such as dependency graph and Dependabot alerts. Other security features require a GitHub Advanced Security (GHAS) license to run on repositories apart from public repositories on GitHub.com.
To learn about the security features available to your enterprise, see Documentação de segurança do código.
To learn about the extra security features available with a GitHub Advanced Security license, see Sobre a Segurança Avançada do GitHub.
