A practical tool for everyday decisions
Jatzo brings together sender and message checks, supported attachment inspection, QR codes read from pictures, PDFs and Office documents, connection warnings and plan-based network and reputation evidence. We explain what was checked, what was unavailable and what to verify next.
Our guides offer beginner and advanced explanations. Reports use the same Case ID as your history so an individual or their IT adviser can discuss the same evidence. Jatzo supports your judgement; it cannot guarantee that a message is safe.
Business workspaces provide individual logins, one allowance shared by the team, and admin and moderator access to retained business reports.
