 ## PII Masking 2.0
 
+<Image img={require('../../img/pii_masking_v2.png')}/>

 This release brings improvements to our Presidio PII Integration. As a Proxy Admin, you now have the ability to:
 
 - Mask or block specific entities (e.g., block medical licenses while masking other entities like emails).
 - Monitor guardrails in production. LiteLLM Logs will now show you the guardrail run, the entities it detected, and its confidence score for each entity.
