Meet the Team
ZYPHERON is founder-led by technical leadership with direct experience across software engineering, offensive security, and practitioner workflows.

Harrison McCall
Founder & CEO
Harrison started in backend engineering across C++, Python, and Go, then moved deeper into offensive security after seeing the same classes of weaknesses reach production systems. That background shapes ZYPHERON's focus on practical assessment workflows, evidence quality, and tools that respect sensitive security data.
ZYPHERON is built around a simple product principle: AI should accelerate security work without taking control away from the operator or moving assessment data into unnecessary cloud systems. The product direction centers on local-first workflows, explicit review, repeatable evidence capture, and reporting that technical teams can defend.
Background
Product Principles
ZYPHERON prioritizes operator control, transparent evidence, and workflows that can be repeated by internal teams and pentest firms without relying on scattered notes or opaque automation.
Product decisions are evaluated against the same standard: keep sensitive assessment data close, make AI assistance reviewable, and help teams turn technical work into reports leadership can act on.
