GuardBox keeps the risk

A sandboxed container for WhatsApp, Telegram, and email. Files and images are redirected and opened inside a single-use cloud sandbox, the moment they arrive — far from your device. The exploit isolates in the box.

The problem

The rise of AI-powered automation for finding vulnerabilities and crafting payloads means a PDF, JPG, or DOC can now compromise your phone on a much larger scale.

CVE-2019-11932 (WhatsApp GIF), CVE-2020-8899 (Samsung Qmage), Pegasus and ForcedEntry all weaponized images and files to compromise phones — many with zero clicks. Today, attackers also disguise APK installers and RAR payloads as PDFs, JPGs and DOC receipts forwarded from people you trust.

Messaging apps

WhatsApp and Telegram don't protect your device out of the box — you decide whether to trust what you receive.

Disguised payloads

APK installers and malware re-iconned as a PDF, JPG invitation or DOC receipt.

Zero-click exploits

CVEs in image and document parsers can fire the moment a thumbnail loads.

Isolation.

Every file is opened inside a short-lived, isolated sandbox the moment it arrives — the exploit fires there, not on your device.

WhatsApp

Forward or share media directly into your GuardBox for safe viewing.

Telegram

Add the GuardBox bot to chats and groups to route incoming media through the sandbox.

Email attachments

Route inbound attachments through GuardBox before they reach your inbox.

EU sandboxes

Isolated, ephemeral containers in EU regions, with possibility to get destroyed after every render.

Who it's for

Two audiences. One quiet bodyguard.

GuardBox protects individuals who live on their phone — and the organizations that defend thousands of them.
