Perl XS module to override all "dangerous" Perl operations (any operation which interacts with the system).

Notably, this module aims to provide the user with an environment identical to the restrictions in place on Google App Engine for Python. Read about Python's App Engine sandbox.

This project is part of the Perl for App Engine effort. This module does not aim to provide unbreakable security. In fact, it's quite breakable. Rather, this module is intended for developers to use to simulate the same restrictions they'd have in a truly hardened environment with minimal effort. (that is, without making them recompile their Perl binary or run their code in some crazy-secure environment)
