# Enabling HTML sanitizer

The HTML sanitizer provides a property to enable or disable the sanitizer for all HTML fields in the system.

By default, the property is set to true for new instances.

## Procedure

2.  Set the properties **glide.html.sanitize\_all\_fields** and **glide.translated\_html.sanitize\_all\_fields** to **true**.
