# Outbound exposure detection

CNA supports outbound internet exposure detection. If CNA detects a workload that based on their security configurations has unrestricted internet access, CNA generates a finding.

This helps you determine which assets have potentially unrestricted access to the internet, taking into account the effect of cloud native security controls, network firewalls and NAT gateways. It allows you to:

* Visualize the complete network path of an asset from source to destination.
* Periodically re-validate the status of an exposed asset.
* Find which security group or firewall rule is causing the exposure.

#### Outbound exposure rules

Outbound exposure rules do not have out of the box rules, but you can create custom ones. See [Create a Network Exposure Rule](/cortex-cloud-runtime-security/cloud-security-rules-and-policies/cloud-security-rules.md).

#### Supported asset types

CNA can detect outbound internet exposure in the following cloud services and asset types:

| **Provider/ Service**        | **AWS**    | **Azure** | **GCP** |
| ---------------------------- | ---------- | --------- | ------- |
| **Managed virtual machines** | Amazon EC2 | –         | –       |

## 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-cloud-runtime-security/network-exposure-detection/outbound-exposure-detection.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.
