# Nucleus integration

> Send security findings to Nucleus for vulnerability management

The Nucleus integration lets you send security findings to Nucleus for vulnerability management.

<Info>
  Available on **NetSec**, **WebNetSec**, and **Pentest Suite** plans.
</Info>

## What is Nucleus?

Nucleus is a vulnerability management platform that aggregates findings from multiple security tools into a single view. It handles deduplication across tools, remediation workflows, and reporting.

## Setting up Nucleus

<Steps>
  <Step title="Get API credentials">
    In Nucleus, obtain your API key.
  </Step>

  <Step title="Configure credentials">
    In Pentest-Tools.com, go to Settings > Integrations > Nucleus and enter your subdomain and API key.
  </Step>

  <Step title="Add projects">
    Add Nucleus projects to send findings to.
  </Step>

  <Step title="Start sending">
    Send findings manually from the findings list, or set up a notification to push findings to Nucleus when a scan completes.
  </Step>
</Steps>

## Sending findings

You can send findings to Nucleus from the [findings list](/core/findings/findings) in two ways:

**Single finding:** open a finding and click **Send to Nucleus**, or use the row action menu.

**Multiple findings at once:** select findings from the list, then click **Send to Nucleus** in the toolbar. Choose the target Nucleus project and the findings are queued for upload. You get a notification when the upload completes.

### Automatic sync via notifications

You can also configure [notifications](/capabilities/notifications) to send scan results to Nucleus automatically when scans complete:

1. Create a notification
2. Select a Nucleus project as the destination
3. Findings are sent when scans finish

## Nucleus projects

Add multiple Nucleus projects to organize findings:

| Field            | Description                       |
| ---------------- | --------------------------------- |
| **Project name** | Display name in Pentest-Tools.com |
| **Project ID**   | The Nucleus project identifier    |

<Tip>
  Create different projects for different environments (production, staging) or teams.
</Tip>

## What gets sent

| Data           | Description                        |
| -------------- | ---------------------------------- |
| **Findings**   | Vulnerability details and evidence |
| **Asset info** | Target IP, hostname, URL           |
| **Severity**   | Mapped to Nucleus levels           |
| **Scan info**  | Tool and scan details              |

### Severity mapping

| Pentest-Tools.com | Nucleus       |
| ----------------- | ------------- |
| Critical          | Critical      |
| High              | High          |

## Tracking sent findings

After sending findings to Nucleus:

* Findings show a Nucleus indicator
* You can track which findings have been sent
* Avoid duplicate submissions

## Troubleshooting
