InboxGuard for Microsoft 365 / Security AI Solutions
Protect the payments that flow through your inbox.
InboxGuard adds onto Microsoft 365 to catch what gets through. Microsoft Defender filters first. InboxGuard takes a second look at every message that lands in your inbox and flags the fake invoices, bank-detail changes, and impersonation that slip through, minutes after they arrive.

Every message, ten checks
What InboxGuard looks for in every email
Each new message is read with its full headers and scored against ten checks drawn from the tricks real scams use every day.
- Payment & secrecy requestsBank-detail changes, gift-card asks, and keep-this-between-us requests get extra scrutiny.
- Staff & executive impersonationMail pretending to come from your owners, executives, or finance team gets flagged fast.
- Lookalike domainsOne letter swapped or one character changed, spotted and scored.
- Reply-to mismatchesReply-to and bounce addresses compared against the sender you see.
- Sender authenticationSPF, DKIM, and DMARC results verified on every message.
- Brand impersonationMail dressed up as Microsoft, your bank, or a delivery brand gets a hard second look.
- Pressure languageUrgent demands, hard deadlines, and secrecy pressure raise the score.
- Disguised & risky linksShortened, redirected, and look-alike links unwrapped before anyone clicks.
- Risky attachmentsAttachment types known for carrying booby traps are treated with suspicion.
- First-time sendersA first email from a new sender earns a closer look, especially when it asks for money.
