When you provide services to multiple clients through a Managed Service Provider, you may want to give your MSP access to see their projects and clients.
Here are the steps:
1- Create a Pentester Team for the MSP
2- Add pentester users for the MSP with the role Pentester (Project Only).
3- Add the user to the MSP Team
4- Add the MSP team to the client default pentester teams. In this way, when a project is created to this client, all the MSP users will see it.
