How to Lock Down Browsing with Website Whitelisting

In many business and public environments, controlling web access is essential for security, productivity, and compliance. Whether for corporate workstations, educational institutions, or public kiosks, organizations need effective ways to restrict browsing to only approved websites. Website whitelisting, combined with features like locking an iPad to one app or enabling Android one app mode, ensures a controlled and secure browsing experience.

The Importance of Website Whitelisting

Website whitelisting is a security measure that allows access only to specific, pre-approved websites, blocking all other web content. This is particularly useful for businesses, schools, and kiosk systems where unrestricted browsing could lead to distractions, security risks, or compliance violations.

Key Benefits of Website Whitelisting:

• Enhanced Security: Prevents access to phishing sites, malware, and unauthorized content.
• Improved Productivity: Ensures users stay focused by restricting distractions.
• Regulatory Compliance: Helps businesses meet industry regulations and policies.
• Reduced IT Workload: Minimizes the need for constant monitoring and web filtering.

How to Whitelist a Website

1: Identify Approved Websites

Before setting up website whitelisting, determine which websites should be accessible based on the organization’s needs. For example:

• Schools: Limit access to educational websites only.
• Workplaces: Restrict browsing to job-related resources.
• Retail Kiosks: Allow only the company’s website and payment portals.

2: Use a Whitelisting Solution

Organizations can implement whitelisting using built-in device settings, third-party software, or mobile device management (MDM) solutions.

For iPads: Locking to One App with Approved Websites

To enforce whitelisting on an iPad, you can use Guided Access or an MDM solution.

Using Guided Access (Basic Lockdown Mode):

1. Open Settings> Accessibility> Guided Access and enable it.
2. Launch the required web browser (such as Safari) with the whitelisted website loaded.
3. Triple-click the Home button (or Side button on newer iPads) to start Guided Access.
4. Adjust settings to disable navigation controls, preventing users from exiting the website.

Using MDM to Lock iPad to One App & Whitelist Websites:

1. Deploy an Apple MDM solution (e.g., Jamf, Mosyle, or Apple Business Manager).
2. Configure Single App Mode to lock the iPad to a kiosk-friendly browser.
3. Set up website whitelisting in the MDM policies to allow only approved sites.

For Android: Enabling One App Mode & Website Whitelisting

To restrict browsing on Android devices, use Android Enterprise MDM or kiosk mode.

Using Android One App Mode:

1. Install an MDM solution like Scalefusion, SureMDM, or Google’s Android Enterprise.
2. Lock the device to a single browser app.
3. Configure the browser to allow only whitelisted websites and block all others.
4. Disable navigation and address bar settings to prevent users from accessing unauthorized content.

Using Android Kiosk Mode for Website Whitelisting:

1. Install a kiosk browser app that supports whitelisting (e.g., Fully Kiosk Browser or SureFox).
2. Set up URL restrictions to permit access only to specified sites.
3. Disable external links and unauthorized navigation.
4. Enable auto-restart to reset the session after each use.

Best Practices for Website Whitelisting

• Regularly Review Whitelisted Websites: Keep the list updated to ensure users have access to the most relevant and secure sites.
• Implement Multi-Layered Security: Combine website whitelisting with firewall rules, network filtering, and endpoint security.
• Use MDM for Centralized Management: If managing multiple devices, deploy an MDM solution for easy monitoring and policy enforcement.
• Test the Whitelist Configuration: Before deployment, verify that only the approved websites are accessible and that navigation controls are restricted.

Locking down web access through website whitelisting ensures that users stay focused, secure, and compliant with organizational policies. Whether using an iPad locked to one app or Android one app mode, businesses and institutions can create a controlled browsing environment that prevents misuse while optimizing device functionality.
