Is protect-usb.mimecast.com safe?

Our automated security review found no threat indicators on protect-usb.mimecast.com, so it appears legitimate. All 90 antivirus engines we queried report it clean, and the domain is 23.6 years old, registered on February 20, 2003 — established domains are far less likely to be scams. Even so, always double-check the exact address in your browser, because phishing emails routinely spoof real, trusted domains like this one.

protect-usb.mimecast.com has a Safety Score of 92/100 (Safe). Core checks and semantic analysis found no material threat at scan time. Treat unexpected login or payment requests with normal caution.

Yes — and this is worth understanding. Even trustworthy domains get spoofed in phishing emails (a fake message that only looks like it's from protect-usb.mimecast.com), and legitimate sites are occasionally compromised on specific pages. A clean verdict means the site itself checks out today; it does not mean every email or link claiming to be from protect-usb.mimecast.com is genuine. Always reach the site by typing the address yourself rather than clicking links in unexpected messages.

No — all 90 antivirus and blocklist engines in our malware network currently report protect-usb.mimecast.com as clean. That's a good sign, though antivirus coverage is only one of the many signals we weigh, and brand-new scam sites can appear clean before vendors catch up.

No — protect-usb.mimecast.com is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.

protect-usb.mimecast.com is 23.6 years old, registered on February 20, 2003 through MarkMonitor Inc.. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.

No — protect-usb.mimecast.com has an invalid or broken SSL certificate, so browsers will show a security warning. Combined with the other signals, we recommend avoiding it.

protect-usb.mimecast.com resolves to an IP operated by Mimecast North America Inc in US (Commercial). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.

This report is a record of the scan run on September 16, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about protect-usb.mimecast.com has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
