Valentin Radu/Pent: Execute Untrusted Processes with Enhanced Filesystem and Network Security Using Native OS Features

Transform Your Process with Pent: The Lightweight Sandbox Solution

Pent is a powerful tool designed for developers who want to run untrusted processes safely, minimizing risks without the burden of heavy containers or VMs. Here’s how Pent stands out in the realm of process containment:

  • Lightweight and Efficient: Operates natively on macOS and Linux, offering unparalleled filesystem and network control.
  • Simplified Configuration: Zero-configuration profiles make it easy to set up. Just run pent config add --global @profile-name.
  • Strong Isolation:
    • Filesystem Isolation: Restrict access to specific paths using a shadowing technique, ensuring unlisted files remain hidden.
    • Network Control: Gate access through a built-in proxy that enforces domain allowlists for safe outbound connections.

Remember, Pent isn’t a full security tool; it’s a safeguard for untrusted processes on your workstation.
