# Cortex Xpanse Product Security

Cortex Xpanse defines your public internet attack surface and tells you what you need to do to minimize risk. You’ll know what to do first, how to fix it, and what it means to your organization. To keep your information safe, Cortex Xpanse is designed with multiple layers of protection, distributed across a scalable, secure infrastructure.

These layers of protection include:

* Cortex Xpanse data at rest are encrypted using 256-bit Advanced Encryption Standard (AES). Cortex Xpanse data is stored in a combination of Amazon Web Services (AWS) and Google Cloud Platform (GCP).
* Cortex Xpanse uses Secure Sockets Layer (SSL)/Transport Layer Security (TLS) to protect data in transit between Cortex Xpanse application and Cortex Xpanse servers.
* SSL/TSL creates a secure tunnel protected by 128-bit or higher Advanced Encryption Standard (AES) encryption.
* Two-factor authorization (2FA) and Single sign-on (SSO) is available for an extra layer of security at login.
* Cortex Xpanse applications and infrastructure are regularly tested for security vulnerabilities and hardened to enhance security and protect against attacks.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xpanse/reference/cortex-xpanse-product-policies/cortex-xpanse-product-security.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
