About This Launch
Domain Armor is a free, no-signup checker that scores a domain's public email authentication, HTTPS, browser headers and DNS out of 100. It reads only public data and is not a penetration test or a security certificate.
Why I Built This
Domain Armor gives site owners a quick, passive read on the basic security setup of their domain.
