# Security

> Safely executing untrusted code

Running code you don't trust is always fraught with danger. When using the Riza
Code Interpreter API, we take the following precautions to make sure code
execution is fully isolated.

* Code is executed inside a secure [WebAssembly](https://webassembly.org/) sandbox.
* WebAssembly modules are not shared across executions.
* By default, code sandboxes have no filesystem or network access.
* Environment variables and command line arguments must be explicitly passed into the sandbox.
* Every execution is subject to [resource limits](/reference/limits).
* Script inputs and outputs are not logged.

If you have any questions, or need to report an issue, please email us at
[security@riza.io](mailto:security@riza.io).

## Self-hosted / single-tenant

You can deploy Riza on your own infrastructure using our [self-hosted product](/enterprise/quickstart). We also plan to offer a single-tenant hosted product.

If you're interested in either of these options, please email us at
[hello@riza.io](mailto:hello@riza.io) or [schedule a
call](https://calendly.com/d/4dw-j7d-hwc/30-minute-riza-discussion).
