Deterministic Security, LLC (DTRSEC) is a Delaware LLC founded in June 2017 as to commercialize the REnigma cyber investigation technology licensed from the Johns Hopkins University Applied Physics Laboratory (JHU/APL). The REnigma technology was originally developed by the co-founders of DTRSEC along with an outstanding team of other researchers at JHU/APL over the course of several years working with the US Department of Defense (DoD) and the US Department of Homeland Security (DHS).

Prior to the founding of DTRSEC, REnigma was selected as one of eight technologies from across the nation's research laboratories for inclusion in the DHS Transition to Practice Program (TTP) for the 2016 class of technologies (See page 25 of the TTP guide and the DHS Press Release). The TTP program provided training, testing, and other resources to help transition the technology from JHU/APL into the DTRSEC startup company. News websites that covered the the founding of DTRSEC include cyberscoop and AFCEA. Since starting the company, the co-founders have led development of the technology from its mature research prototype phase into a full commercial product by working closely with our early pilot partners to build up the technology into a powerful solution to help organizations keep their networks safe. If you would like to know more about REnigma and how it can help reduce your enterprise's costs and significantly improve your security posture, please contact us.

Dr. Julian B. Grizzard, Co-Founder and President

Dr. Julian B. Grizzard (Julian) is a seasoned computer security expert with over 15 years of experience starting with his graduate work in computer security at the Georgia Institute of Technology (Georgia Tech) specializing in honeynets and studying methods to recover from rootkit installations. After completing his Ph.D. and earning an Engineering Entrepreneur Certificate at Georgia Tech in 2006, Julian joined the Johns Hopkins University Applied Physics Laboratory (JHU/APL) as a Research Scientist developing advanced cybersecurity technology for the US government. Of the many powerful technologies Julian was lead researcher for at JHU/APL, REnigma was selected as one of eight technologies for the 2016 DHS Transition to Practice (TTP) class to commercialize the technology and make it widely available to both the government and private sectors. Julian left JHU/APL to start DTRSEC with Jim in 2017.

James M. Stevens, Co-Founder and Executive Vice President

James M. Stevens (Jim) is an experienced computer engineering and security researcher with 14 years experience in systems programming and hardware design. Jim earned his B.S. in Computer Engineering at the University of Kansas in 2006, his M.S. in Computer Science at the University of Arkansas in 2009, and studied at the University of Maryland as a Ph.D. student/candidate from 2009 to 2013. During graduate school, Jim performed research in compiler and operating system design for hybrid CPU/FPGA systems and memory controller technology for hybrid DRAM/non-volatile RAM memory systems. Jim worked at JHU/APL from 2013 to 2017 as a cybersecurity researcher, where he invented the Guard Lines exploit mitigation technology (US Patent No. 9804975) and was a co-developer of the record and replay technology and REnigma project, focusing on designing frameworks for virtual machine introspection of malware and software debugging. Jim left JHU/APL to start DTRSEC with Julian in 2017.
