# Targets

Targets are assets that you monitor with Halo Security. They are represented by either a hostname (like `www.example.com`) or an IP address (like `255.255.255.255`).

Most organizations use Halo Security to understand their full risk across their external attack surface. They use our [discovery services](https://docs.halosecurity.com/docs/platform/discovery) to identify and add targets to their account. You can also add targets on a case-by-case basis as necessary.

## Services

Services can be added to targets. By default, all targets with websites are monitored for [website security](https://docs.halosecurity.com/docs/platform/websites) and [firewall configuration](https://docs.halosecurity.com/docs/platform/firewalls) issues.

You can optionally add Application Scanning (DAST) services to any target within your account. You can also add targets to PCI scope.

## Preview

For targets that are running accessible web servers, a webshot preview is generated that displays the contents of the webpage. This functionality allows you to quickly see web applications that are similar or that may be generating errors.

{% hint style="info" %}
Webshots are generated automatically when HTTP servers are detected during scans. The connections originate from crawlproxy.halosecurity.com (`54.187.125.96`). If you see web servers that are missing a preview, you may need to add us to the allowlist.

## Tags & Filtering

Tags and filtering allow you to group targets and view only targets matching certain criteria.
