Warns before sending SSNs, bank or card details. Flags wire-fraud attempts and malicious links. Message text stays on your device. Office Guard Email DLP watches your email in both directions, inside Gmail, Outlook.com and Yahoo Mail. It warns you before you send a message containing sensitive data — and it warns you when a message you've just opened shows the pattern of a fraud attempt, or carries a link to a site known for phishing or malware. All of it happens in the page, as you work, with no change to how you use email. BEFORE YOU SEND Office Guard checks your draft for Social Security numbers, credit card numbers, bank routing and account numbers, SWIFT/BIC codes, driver's license and passport numbers, dates of birth, bank names and addresses, and wire transfer instructions. Wire details are treated as the top priority, because wire fraud targeting real estate closings is one of the most costly email attacks there is. Every warning has a "Send anyway" option. Office Guard never blocks an email — it pauses to check that a sensitive message is deliberate, then respects your decision. WHEN MAIL ARRIVES That same wire fraud arrives by email, and it arrives looking ordinary. Office Guard puts a banner above a message when it sees: Payment or wire instructions that have changed — the single most common form this fraud takes, and one that usually contains no numbers at all, just a sentence saying the account details are different now. A payment request pushed with urgency — details combined with pressure to act today, immediately, or before closing. A request for identity documents — someone asking you to email a Social Security number, driver's license, passport or date of birth. A sender address that doesn't look right — a domain closely resembling another one already in the conversation, or a display name that disagrees with the address behind it. A link to a known dangerous site — link addresses in the message are checked against Google's Web Risk database of phishing and malware sites, and flagged before you click. These checks are deliberately narrow. They look for the shape of a fraud attempt, not for sensitive data in general — you receive account numbers and dates of birth legitimately every day, and warning you about those would be noise you'd learn to ignore. YOUR MESSAGES STAY ON YOUR DEVICE Every scan of your message text runs on your own computer. Nothing you write and nothing you receive is sent to Office Guard, to a third party, or to any server — not the text, not the sender, not the recipients, not attachments. Link checking is the one part that reaches the network, and it sends only the link addresses themselves. When a message you've opened contains links, those addresses alone go to Office Guard's own service, which checks them against Google Web Risk and returns a verdict. Nothing else about the message accompanies them. Encrypted send works the same way. When you click "Encrypt this instead," your draft is handed to our encryption page so you don't have to retype it — and the message is encrypted in your browser before anything is sent. Office Guard keeps no record of your messages because it never receives them. MADE THE WAY YOU WANT IT Three sensitivity levels — Notify only, Balanced, or Strict — control how often you're asked to confirm rather than simply shown a quiet heads-up. Any individual check can be switched off, on either the sending or the receiving side. The "Risk Low" confirmation that appears when nothing is found can be turned off entirely if you'd rather see warnings only. WHO IT'S FOR Real estate agents, attorneys, accountants, and anyone who emails financial or personal information for a living — who can't afford one mistaken send, or one convincing email that isn't what it claims to be.
