3.3 Configuration
While different users will have different security needs, casual users who interact with PDFs in unsecure
environments should enable Protected Mode all the time.
There are a limited number of cases where you might want to disable Protected Mode:
• When you want to use an unsupported feature such as Accessibility on XP.
• In enterprise settings where PDF workflows are entirely confined to trusted environments under an
administrator's control.
• If you have third-party or custom plugins that cause issues when running in Protected Mode. For
example, some workflows that use ActiveX plugins may not work by default.
