Along with Dr. Julian Grizzard, I co-founded Deterministic Security, LLC (DTRSEC) to commercialize the REnigma technology we invented at APL. Since 2017, we have worked with defense contractors and cybersecurity companies to help our users better understand how malware works.REnigma is an interactive malware analysis sandbox that records everything that happens on a system at full speed and allows it to be perfectly replayed at a later time. During replay, REnigma can see everything: system calls, DLLs, user space functions, network traffic, data structures in memory, register states, and all instructions. To make sense of the vast amount of data available, REnigma includes analyzers that automate the tedious and repetitive parts of tearing apart malware. You can also easily share the recording with others to perform collaborative analysis and help inform your friends of the latest malware threats with greater detail than any current threat intelligence sharing infrastructure.Fundamentally, DTRSEC is about lowering the cost of malware analysis for your organization and making your team more effective. We will help you set up a world-class and secure malware analysis environment that is resilient against the most advanced threats, integrate it with your other technology investments, and train your team to perform fast, safe, and complete analysis, allowing you to better defend your network against APTs and criminals.

At APL, I invented Guard Lines, a CPU-based memory corruption detection capability with minimal performance overhead. This patented technology ("Hardware-Enforced Prevention of Buffer Overflow" US 9804975) enables CPUs to directly detect buffer overflow and use-after-free bugs as soon as they occur and prevent attackers from exploiting these bugs. Additionally, I was the co-principal investigator of REnigma. REnigma is a tool to analyze and reverse engineer advanced malware; it is based on APL's Virtual Machine Record and Replay (RnR) dynamic analysis technology developed by Dr. Julian Grizzard. The underlying RnR engine allows REnigma to record the malware's execution at full speed and perform in-depth analysis and forensics during replay. In 2015, REnigma was selected to participate in the Department of Homeland Security's Transition To Practice (TTP) program and is currently seeking government and private sector partners for early stage pilot deployments. In early 2016, REnigma was deployed in operations to defend APL's internal network against cyber attacks.I have also worked on research, development, test, and evaluation projects in other areas of cyber security, software assurance, homeland security, space exploration, and air/missile defense.
