The Cepher is put out by WND and is supported by the Hebrew Roots movement which denies essential doctrines of the Christian faith, such as the deity of Christ. I firmly believe that the Cepher is dangerous and deceptive. It includes 87 books as authoritative/historically relevant scripture (such as the book of Jasher, which is a medieval forgery). The Christian Bibles include 66 books (without the apocrypha as it’s not inspired). The fact the Cepher publishers consider 21 other books as canonical and almost 2000 years of church history doesn’t should give pause. More information can be found at the link and other sites through a Google search on Cepher.
