# Nuclei

> Run Nuclei scans for attack-surface discovery and sync results into Snapsec ASM.

## Nuclei Integration with Snapsec ASM

The **Nuclei integration** allows Snapsec ASM to run template-based reconnaissance and exposure detection across your external attack surface.\
Once connected, ASM can trigger Nuclei scans, ingest the findings, and update asset exposure status automatically.

***

## 1. What This Integration Does

With Nuclei connected to ASM, you can:

* Discover exposed services, misconfigurations, and weaknesses.
* Scan domains, subdomains, IPs, and URLs monitored by Attack Surface Management.
* Automatically ingest findings into ASM’s **Exposures** section.
* Enrich assets with detected technologies, fingerprints, and metadata.

ASM uses Nuclei templates to continuously test your perimeter for security gaps.

## 2. How to Enable Nuclei Integration

1. Go to **ASM → Integrations**.
2. Find **Nuclei** in the list of available integrations.
3. Click **Install** or **Configure**.
4. Choose how Nuclei will be executed:
   * Snapsec-hosted scanning engine
   * Your custom Nuclei runner (self-hosted)
5. Save the configuration.

Once installed, the Nuclei adapter appears in **Active Adapters**.

## 3. How Nuclei Works Inside ASM

After setup, ASM will:

* Auto-run Nuclei scans during scheduled discovery cycles.
* Trigger Nuclei when new assets (subdomains, hosts, IPs) are found.
* Parse JSON results and convert them into **Exposures**.
* Display findings in:
  * Exposure Feed
  * Asset Exposure Panel
  * Technology & Service Detection

Each asset is updated with:

* Severity
* Template ID
* Description
* Evidence
* First/Last Seen timestamps

***

## 4. Supported Nuclei Use Cases

* Subdomain & host vulnerability detection
* Exposure fingerprinting
* Misconfiguration scanning
* Technology & service identification
* API endpoint probing
* Asset-level risk scoring enrichment

***

## 5. Troubleshooting

**No results appearing?**

* Ensure your Nuclei runner has internet access.
* Validate that assets resolve (DNS, IP reachable).

**Adapter stuck in “Waiting”?**

* Restart your Nuclei engine or re-authorize your configuration.

**Templates not running?**

* Check if your Nuclei install includes the official template repository.
