About me
I'm David, founder of Encrypted Syntax Institute. I help startups, small businesses, and security professionals reduce risk through authorized security assessments and hands-on pentesting mentorship.
I assess web apps, APIs, networks, and attack surfaces. Clients receive confirmed findings, severity ratings, evidence, reproduction steps, remediation guidance, and a clear split between launch blockers and lower-priority issues.
I bring 15+ years in cybersecurity, six years in U.S. Army (25B), an M.S. in Cybersecurity and Information Assurance, PNPT, and CompTIA certifications.
