About protonmail.com

We reviewed protonmail.com and found a mix of positive and cautionary signals. The site does not currently look like a confirmed scam, but the evidence is not strong enough to treat it as fully established either. The current trust score is 71/100. Key signals include cybersecurity tools and services, low SmartCustomer score, and corporate registrar evidence. We also saw reputation caution signals from third-party review sources, so commercial claims should still be checked independently. Verify key details and recent independent feedback before relying on this site for important actions.

FAQ

Is protonmail.com safe?

Current analysis does not clearly confirm that protonmail.com is safe. Important context includes cybersecurity tools and services and low SmartCustomer score. Independent verification is still recommended before relying on it.

Why does protonmail.com have mixed reputation signals?

Key factors include registrar information (MarkMonitor, Inc.), hosting in CH, a domain age of 16 years, and presence in public traffic rankings. Major malware and phishing engines did not report active blacklist detections at the time of review, but reputation-related warning signals were still present. The trust score blends security detections, domain and infrastructure signals, on-page behavior patterns, and public review history when available. The overall assessment remains mixed because third-party reputation sources do not point to a fully consistent trust profile.
