Use case
Run community and GitHub PowerShell with OS-level blast-shield isolation beside signing and approval.
Problem: MSPs inherit scripts from forums, GitHub, and peer shares. Signing proves integrity at dispatch; sandboxing proves runtime behavior stayed inside the lane.
Trustholm process sandboxing is opt-in (AllowProcessSandboxing). Assign platform:third-party-readonly-v1 to community scripts: no outbound network, no child processes, stripped debug privilege. Credentials still answer who ran the script; the sandbox answers what the process could reach.
Pair with code signing and approval workflow. Export sandboxReport fields in security audit for assessor review.
No. Sandboxing is a blast shield beside Authenticode and tenant signing policy. Both layers are recommended for third-party content.
