ProtonMail lookalike domains
Greyphish has recorded 96 domains that resemble ProtonMail since February 2026, 8 of them in the last 90 days. Most of them (71%) are typosquats, a keystroke or two away from the real name. .com carries 96% of them, out of 4 endings in all. 2 certificates for unregistered .ph names (registry wildcard) are excluded: the registry answers for any name under that ending, so nobody had to register one to get a certificate for it.

Where they are registered
For the 88 with a registrar in WHOIS (92% of all). Brand-protection registrars mostly hold defensive registrations made by brands themselves, so a domain there is more likely the brand's own than an imitation.
| Registrar | Lookalikes | Share | Type |
|---|---|---|---|
| Media Elite Holdings | 11 | 12.5% | Retail |
| NICENIC INTERNATIONAL GROUP | 10 | 11.4% | Retail |
| Cloudflare | 7 | 8.0% | Retail |
| Namecheap | 7 | 8.0% | Retail |
| Spaceship | 7 | 8.0% | Retail |

Recent examples
The 10 most recent, written with [.] so they cannot be clicked. The brand's own domains and registrations held by brand-protection registrars are left out. A lookalike resembles ProtonMail; it is not necessarily malicious, and none of these is a claim about who registered it or why.

Greyphish is not affiliated with ProtonMail. Domains listed resemble ProtonMail by spelling; registration alone says nothing about intent. Counts cover domains first seen in public Certificate Transparency logs and ICANN zone files; domains that Greyphish customers watch are excluded.
