2026 Salesforce Data Breach Roundup: What You Need to Know
The wave of Salesforce-targeted data theft that started late last year shows no signs of slowing down.

How to Protect Your Salesforce Org
Salesforce recommends these immediate actions for all Experience Cloud users:
Audit guest user profiles — restrict access to the absolute minimum objects and fields needed
Set Org-Wide Defaults to “Private” for all objects under Sharing Settings
Disable Public APIs by unchecking “API Enabled” in guest user System Permissions
Restrict visibility by unchecking “Portal User Visibility” and “Site User Visibility”
Disable self-registration if unauthenticated account creation isn’t required
