You must give Snyk access to your environment, to allow Snyk to scan that environment. Access is provided by Snyk integrations.
The type of integration you need depends on what systems you use, and what you want to scan.
Example: set up a source control integration
To scan open source libraries (using Snyk Open Source) or your application code (using Snyk Code) from a Git-based source code repository, you will need to connect using a Git repository integration. Snyk has pre-built integrations for GitHub, GitHub Enterprise, Bitbucket Cloud and other repositories.
First, log in to the Snyk Web UI (app.snyk.io), and select Integrations > Source control.
If an integration is already configured for your Organization, it is marked as Configured.
Next, click the source control system (for example, GitHub) to integrate with Snyk.
Finally, to grant Snyk access permissions to the integrated source control system, enter your account credentials and save your details when prompted.
