GSN is a place to store information about a particular service (http, smb, ftp, etc). These notes are global and not attached to a single Engagement, Host or Port. Next time you encounter the same service, you will see your Global Service Notes for that specific service.

## Global Service Notes Manager

**URL:** <https://pentest.ws/gsn>

The GSN Manager is your central repository for all Global Service Notes. Typically GSNs are created using the Port Page when you encounter a service such as HTTP or SMB. However, here you can manually add a service and attach your notes.

## Tier Availability

**Global Service Notes** is available on all tiers.
