What MxGuard Business stops

MxGuard defends against the full range of modern email threats:

• Phishing — credential-harvest pages, fake login flows and OAuth-consent traps.
• BEC and impersonation — CEO fraud, invoice redirection, supplier impersonation and gift-card scams.
• Malware and ransomware — ClamAV scans every attachment, including archives; macro-bearing Office documents and HTML smuggling are scored heavily.
• Bulk spam and UCE — classic spam, snowshoe and hailstorm campaigns, with near-zero false positives on legitimate bulk mail.
• Lookalike domains — homoglyph attacks, doubled letters and ccTLD swaps, checked at the envelope, the From header and the reply-to.
• Backscatter and spoofing — SPF/DKIM/DMARC enforcement, plus ARC sealing that survives forwarding.

These payload-free, well-crafted attacks are exactly where MxGuard's LLM layer is strongest — and exactly where legacy filters tend to fail.
