Live on Kickstarter

Back GuardBox. Keep the risk off every phone.

We're launching GuardBox on Kickstarter — a sandboxed container that intercepts images and attachments from WhatsApp, Telegram, and email, and opens them inside ephemeral EU cloud sandboxes. Help us put it in the hands of journalists, activists, families and businesses across Europe.

An image is not just an image

Real threats, not hypotheticals.

Messaging apps

WhatsApp, Telegram, and email clients decode whatever they're sent — none of them add a protective layer of their own.

Disguised payloads

Malware is routinely dressed up as an ordinary photo or document to pass casual inspection.

Why auto-preview must be off

CVEs in image and document parsers can fire the moment a thumbnail loads — which is exactly why GuardBox's setup starts with turning auto-download and auto-preview off, so nothing renders before you choose to route it through the sandbox.

What you get

WhatsApp

Share-sheet intake, streamed, never stored on-device.

Telegram

Bot-based, server-to-server intake.

Email attachments

Routed to the sandbox before a client parser touches them.

Safe Viewer

Pixel-based rendering — nothing decoded on your device.

EU sandboxes

Ephemeral, isolated, EU-hosted processing.

API & SDK

For teams who want GuardBox wired into their own tools.

Who it's for

Individuals

Activists, journalists, and families — free tier across iOS, Android, and web.

Businesses

Agencies and enterprises — REST API, SSO, audit logs, GDPR and NIS2 alignment.

Why crowdfunding

Independence

No VC pressure, no data monetization to satisfy investors.

Faster shipping

Funded directly by the people who'll use it.

A perpetual free tier

Self-hosting stays free forever — that's the whole point.
