About ISM gateway retention
Veracode automatically deletes an Internal Scanning Management gateway and its associated endpoints if it has no scan activity for four months. When Veracode deletes a gateway, the Veracode Platform displays the name of the deleted gateway on the Internal Scanning Management page.
To prevent Veracode from deleting a gateway, schedule a recurring Dynamic Analysis scan that uses the gateway for internal scanning.
To scan internal web applications or REST APIs after Veracode deletes your gateway, you must create a new gateway and endpoint.
