Security builder / operator

Harrison McCall

I build AI security systems, firmware defense tooling, and offensive research infrastructure for authorized operators.

System 01

Zypheron IDE

An AI security workspace built for operators who need faster reconnaissance, sharper assessment flow, and a direct path from question to action.

Zypheron exists for security work that cannot wait on bloated dashboards or committee-built tooling. It is the operator interface for AI-assisted cyber work.

FirmwareGuard

Firmware sovereignty for people who want their machines under their control, not buried under opaque vendor assumptions.

FirmwareGuard focuses on CPU-level firmware visibility and defensive control across Intel ME, AMD PSP, and hardened workstation environments.

Erebus

Open-source C2 framework for authorized red-team operations and security research.

Erebus is built for controlled research, operator discipline, and serious offensive security teams working inside legal authorization.

What I Offer

Partnerships first. Selective consulting second.

Security Consulting

Focused review, threat modeling, infrastructure assessment, and practical hardening for teams with real exposure and no appetite for theater.

AI / Security Systems

AI-assisted security workflows, operator tools, automation paths, and research systems built around the way technical teams actually work.

Firmware and Tooling

Firmware security research, privacy-focused workstation strategy, and specialized tooling for organizations that need control below the OS.

Builder's Standard

I do not separate security from execution.

Harrison McCall builds the systems he talks about: security products, firmware tools, AI workflows, red-team infrastructure, and the web surfaces around them. The work is technical, direct, and judged by whether it gives serious operators more control.

The best fit is a hard problem with clear authorization, high trust, and room to build something that matters.

Direct contact

For serious security work, partnerships, or systems worth building.

Send the context, the objective, and what makes it worth the time. If it fits, the conversation can move fast.
