About Jim Frazer & Son Cryptography

Spun off from Information Security Systems Incorporated in 2009 as a separate business to focus on commercial cryptography, Jim Frazer & Son Cryptography maintains the same group of masterful cryptographers and high standards that have made ISSI a leader in private cryptanalysis.

Information Security Systems Incorporated (ISSI) was founded in 1985 by Dr. Jim Frazer, a Distinguished Member of the Cryptomath Institute, a distinction that NSA reserves for it's outstanding cryptomathematicians. 

Year by year, as the consulting work increased, Dr. Frazer recruited scientists, engineers and mathematicians who had demonstrated a high degree of creativity in protecting and attacking information systems.
