INDEPENDENT RESEARCH + ENGINEERING

Secure systems
for an autonomous
world.

0x0 researches and builds secure AI, cyber infrastructure, networks, and autonomous systems.

Technology becomes useful when it stays observable, constrained, and recoverable.

We work on systems that delegate real capability—to models, software, and infrastructure. Our focus is keeping that capability observable, bounded, and recoverable in production.

01
AGENTIC AI

Capability without uncontrolled consequence.

Authorization boundaries, memory integrity, provenance, delegation, and execution controls for LLM agents and multi-agent systems.

02
CYBER SYSTEMS

Reduce implicit trust. Increase useful signal.

Cloud security, SASE, zero-trust architecture, network controls, telemetry, and resilient defensive systems.

03
AUTONOMOUS INFRASTRUCTURE

Automation that can explain, stop, and recover.

Human-supervised autonomy with scoped privileges, traceable actions, independent checks, and reversible execution.
