Authorized defensive cybersecurity

Security & Agent Reliability

RUMBO IA researches and builds secure AI-system controls for systems owned, operated, or explicitly authorized for defensive testing by their owner.

Scope boundary. This work is internal and defensive. RUMBO's commercial CRM/automation product is separate from this security work. Trusted cyber capabilities are not exposed to customers or third parties, and no customer-facing product depends on privileged cyber access.

Secure software & AppSec

Code review, dependency and workflow hardening, threat modeling, vulnerability validation and patch verification for owned or explicitly authorized systems.

Agent security boundaries

Permission checks, tool execution controls, sandboxing assumptions, lifecycle ownership, cancellation safety, audit evidence and fail-closed behavior for AI-assisted systems.

Verification over claims

Findings are reproduced, bounded and falsified before promotion. Prepared actions are distinguished from executed actions, and execution from verified effects.

Incident & reliability analysis

Defensive investigation of failures in systems we control: authorization gaps, unsafe state transitions, resource leaks, tooling boundaries and evidence integrity.
