# Issue Comparison Between Different Scans Most of the ***Risk*** pages contain a functionality to compare scans. Accessed by selecting ***ChangeLog*** option in these Risks pages.

To compare two scans, you must select the **source (FROM)** and the **target (TO)** scans

The **source scan (FROM)** allows to be selected among: * Pre last scan (the previous to the last executed scan) * Baseline (the scan tagged as [Project Baseline](https://docs.xygeni.io/introduction-to-xygeni/key-concepts/project-baseline)) * First Scan (the first scan of the project, by default it's the project baseline) * A specific scan (selected by execution timestamp)

The **target scan (TO)** allows to be selected among: * Last Scan (the last executed scan of the project) * A specific scan (selected by execution timestamp)

{% hint style="info" %} By default, the list will show the differences between the **Baseline** and the **Last Scan**. Any issue tagged as **NEW** means that issue appear into the Target but it does not exist into the Source scan Any issue tagged as **REMOVED** means that issue appear into the Source but it does not exist into the Target scan {% endhint %}

You can **filter** the list by **type of change** (new and/or removed)
