Cyph is a cryptographically secure messaging and social networking service, providing an extreme level of privacy combined with best-in-class ease of use.
Cyph's patented technology — built by former SpaceX engineers, audited by Cure53, and the basis of research presentations at Black Hat and DEF CON — uniquely allows Cyph to solve the major security and usability limitations of conventional solutions.
