About EmailAuth
We make email you can trust
Email is still the front door for most attacks. EmailAuth exists to shut that door, so that the only people who can send email from your domain are the people who should.
Our mission
Make strong email authentication achievable for every organization, even the ones without a large security team.
What we believe
Enforcement should be driven by evidence, not guesswork, so you can reach p=reject without dropping real mail.
Who we serve
From founders and SMEs to global enterprises and the MSSPs who protect them, on Cloud SaaS or on-premises.
