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. Only Cyph automatically mitigates man-in-the-middle attacks (with no manual in-person fingerprint verification), offers both native apps and cryptographically secure web access (thanks to WebSign), and as a bonus protects present-day end-to-end encrypted data from future quantum computing attacks.
