Never on your device — whether you are a journalist, an activist, a family, or a business protecting thousands of employees.
GuardBox is built by GuardBox Labs, an independent research team based in Stockholm, addressing the threat posed by malicious files disguised as legitimate documents. The service isolates potentially dangerous files within remote sandboxes rather than processing them directly on user devices — preventing local compromise regardless of file origin or apparent legitimacy. GuardBox operates EU-based cloud sandboxes and maintains compliance with GDPR and NIS2 regulations from inception.
A PDF, JPG, or DOC can compromise a phone at a much larger scale than a few years ago — AI-assisted payload development has lowered the bar for building convincing, malicious files. Attackers routinely disguise malicious packages with innocent extensions and preview images.
Anyone who wants a safer default for files sent by people they don't fully control.
People handling sensitive communications who can't afford a single bad attachment.
Facing targeted, high-stakes attempts to compromise their devices specifically.
Protecting less-technical members who can't be expected to spot a disguised file.
Organizations operating in restrictive or high-risk environments.
