APIVoid Browser Lockdown: take full control of what your browser can access
Worried about employees visiting unsafe sites, kids browsing unrestricted, or devices being used outside approved websites? APIVoid Browser Lockdown puts you in charge — block every website by default and allow only the ones you trust.
Why APIVoid Browser Lockdown?
• Block everything, allow only what you trust
Enable Lockdown Mode and every website is denied by default — only your approved domains can be reached.

Restrict downloads to specific file types only. All other file downloads are blocked automatically.
• Manage hundreds of browsers from one place
Use the Enterprise remote list feature to manage trusted domains centrally across all your devices from a single remote file.
• Blocked URL log
Every blocked domain is logged with its URL, reason, and timestamp so you always know what was stopped.
• Customizable warning page
Replace the default blocked page logo with your own company logo or name for a professional branded experience.
• Full backup and restore
Export all your settings to a JSON file and restore them on any browser in seconds.
