The advisor retrieves security advisories from configured services. It requires the analyzer result as an input. For all the packages identified by the analyzer, it queries the services configured for known security vulnerabilities. The vulnerabilities returned by these services are then stored in the output result file together with additional information like the source of the data and a severity (if available).

Multiple providers for security advisories are available. The providers require specific configuration in the ORT configuration file, which needs to be placed in the advisor section. When executing the advisor, the providers to enable are selected with the --advisors option (or its short alias -a); here a comma-separated list with provider IDs is expected. The following sections describe the providers supported by the advisor:
