How we write the research
Define the terms, distinguish outside sources from PatientLock conclusions, and connect security measurements to actuarial outcomes only when the evidence supports the relationship.

01Core research

Cyber risk, evidence, assurance, and breach modeling

Research on risk direction, evidence quality, continuous assurance, breach modeling, framework design, high-assurance deployment, vendor evidence, and the relationship between measured security state and real-world loss outcomes.

How the Ford Model Measures Cyber Risk

The Ford Model treats cyber risk as a bounded dynamical system. It asks whether Enforcement and Proof Continuity are strong enough to outrun Decay and Adversarial Pressure, making risk direction explicit instead of reducing the environment to one unexplained score.

02Foundational research

The Risk Floor: The Irreducible Limit of Cyber Risk

The Risk Floor, R_min, names the Ford Model's strictly positive lower bound of residual risk. It defines the irreducible limit toward which sustained enforcement and continuous proof drive modeled risk.

Anchoring Cyber Risk to Real Breach Data

How VitalSec anchors breach modeling to defined populations and outcomes using traceable source data, prospective testing, frequency, severity, and measured time-at-risk.

Why Static Cyber Risk Snapshots Fail

Why configuration drift, changing adversarial pressure, evidence age, and intervention history make cyber risk a temporal measurement problem.

What Healthcare Can Learn from Air-Gapped Security Environments

How restricted computing enclaves and air-gapped operating constraints influenced VitalSec's design, and what those lessons mean for healthcare resilience, local authority, controlled transfer, and proof continuity.
