The Invoice Fraud Checker. A separate yearly licence, not part of a Jatzo subscription.
It sits after your filtering has had its turn, on the message that arrived because nothing about it was technically wrong.
Email arrives, your filtering checks it, it reaches your inbox, and Jatzo gives a second opinion.
A message designed to fool you is built to look ordinary.
A bill arrives for work that sounds plausible. Paying it sends your money to someone else entirely.
Someone has accessed your account, sign in to secure it. The sign-in page is theirs, and now so is your password.
A delivery is held pending a tiny charge. The amount is trivial, which is the point. What they want is the card number.
A familiar contact sends new account details before an invoice is due, and the next payment goes to somebody else.
The Invoice Fraud Checker is a Windows program that keeps the bank details you have confirmed for each supplier. When an invoice asks you to pay somewhere new, it says stop, and says why. It runs on your own computer, and your suppliers' bank details are never sent to Jatzo.

What each plan includesThe Invoice Fraud Checker belongs to the same family and is sold on its own: a separate Windows licence, never part of a subscription here. About invoice checks
The other half of email fraud is the mail sent in your name. If your domain does not tell receiving systems to refuse a fake, anybody can send an invoice from your address to your customers, and it will look exactly like you.
History keeps the subject, score and compact findings. It does not keep the raw email or attachment contents.
Jatzo reads the submitted message and supported attachments to produce the analysis, then releases them from application processing.
History saves the subject, score and compact findings. It does not save the raw email or attachment contents. Subjects may contain personal information.
Supported uploads are processed in restricted workers. This reduces risk; it does not make an attachment safe to open on your own device.
The current email engine uses programmed checks and scoring. It does not send your email to a generative-AI model for analysis.
Jatzo reads the message and its attachments to run the analysis, then releases them. The raw email, its contents and its attachments are not saved in your history. What is kept is the subject line, the score, the short list of findings and a few counts, such as how many links there were, so you can recognise a check later. In your history, links and senders are kept only as keyed fingerprints that cannot be read back, which is how Jatzo notices the same campaign returning. The detailed evidence behind a PDF report, such as the full links, is held in memory for up to 30 minutes and then deleted.
