# Protect sensitive information in logs and analytics

Sometimes, incoming requests contain sensitive or Personally Identifiable Information that should not be included in logs and other forms of analytics.

Link11 WAAP provides the ability to mask specific types of information. This is configured using the *Masking Seed* and *Mask?* fields within [Content Filter Profiles](/console-walkthrough/security/content-filter/profiles.md). 

Note that you should ensure that [the relevant requests are always subjected to the Content Filtering process](/console-walkthrough/security/content-filter/profiles.md#circumstances-where-content-filtering-will-not-occur).
