Relution Decon - Secure Content Filter
Introduction
Starting with version 5.27, Relution for iOS enables the setup of a DNS-based content filter. This feature ensures a secure and focused internet experience by restricting access to selected websites and apps. With AI-powered content categorization, Relution Decon also provides a comprehensive parental control filter with advanced configuration options.
What is Relution Decon?
Relution Decon is an AI-powered add-on for iOS and iPadOS that filters content in real-time, creating a safe digital environment. Using DNS-based content control, Decon blocks unwanted websites and apps, allowing users to work and learn in a protected, distraction-free space.
Relution Decon uses a DNS proxy to forward all requests to the Decon server. Websites are classified and either allowed or blocked according to policy rules. All data transfers are SSL-encrypted, ensuring user activities remain secure.
Decon App
The Decon app is automatically deployed on iOS devices when the policy is installed. It monitors device DNS requests and ensures that only approved content is accessible.
App features:
- Activates a system-wide DNS proxy, which cannot be disabled by the user
- Displays the current status of Relution Decon
- Provides insight into blocked websites and applied filter categories
Recommendation: Ensure sufficient VPP licenses for the app before deployment.
