Central argument

VitalSec is designed to show how protections perform, verify what changed after a repair, and keep the evidence. PatientLock's goal is to establish what that record tells insurers about loss.

Definitions

Terms used in this paper

These definitions establish how the paper uses its core terms before the argument begins.

Telematics
Collection and transmission of vehicle operating data, including measurements that can inform behavior-based insurance.
Control state
The observed condition of a security safeguard within a defined scope and time, compared with what that safeguard is required to do.
Exposure window

1. A More Useful Question About Risk

Two businesses can buy the same security tools and end up with very different protection. At one, the team catches failures, fixes them, and checks that the repairs hold. At the other, gaps build up between reviews. A checklist that says both businesses have endpoint protection, access controls, and backups misses that difference.

That is why Tesla Insurance is worth looking at. Tesla uses data from the car to help assess how it is driven. In cybersecurity, we need a clearer view of how a business's defenses hold up over time, including the months between an insurance application and renewal.

PatientLock's view is that a useful risk measure needs a record behind it: what was observed, what needed attention, what action was authorized, and whether it worked. That record lets a business show its progress and gives a reviewer something concrete to examine.

2. How Tesla Connects Driving to Insurance

Tesla's model is behavior-based auto insurance: the customer buys coverage, and data from the car helps inform the price. This is different from self-insurance, where a person or business retains its own losses. [1]

Tesla says its Real-Time Insurance uses driving behavior and mileage to help calculate premiums. Safety Score is one input, alongside the vehicle, where it is kept, the coverage chosen, and other applicable factors. Premiums can change monthly, rather than with every maneuver. California is an exception: Tesla does not use Safety Score to price its policies there. [2]

Safety Score also gives drivers feedback intended to encourage safer driving. They can see the behaviors being measured and how those behaviors relate to future premiums. [3] The practical lesson is the connection between the score and something the driver can act on.

Usage-based insurance is an established category, described by the National Association of Insurance Commissioners. Tesla makes the idea easy to see: the car collects the data, the driver gets feedback, and that information feeds into the insurance decision. [2,4]

Show people what is happening, what they can change, and how that change affects the next decision.

3. The Cyber Equivalent: Evidence of Control Behavior

A cyber insurance application may ask whether a business has multifactor authentication, endpoint protection, or backups. The next questions are about how well they work: which people and devices are covered, how long a failure went unresolved, and whether a repair restored protection. A completed backup job, for example, answers a different question from a successful recovery test.

Consider a device whose endpoint protection stops reporting. The operator first checks whether the protection has failed or the data feed has stopped. Any needed correction must be authorized, followed by another check of the device. The record needs to show the original problem, the action taken, the result, and anything still unknown. Closing a support ticket does not establish that protection was restored.

Later checks show whether the repair held or the problem returned on the systems being monitored. Missing observations belong in the record too. This gives the security team a history of what worked and what kept failing. It also gives an insurance reviewer a way to examine changes during the policy period.

4. PatientLock's Parallel: Connect Action to Measured State

VitalSec is designed around PatientLock's operating loop: Observe → Decide → Act → Validate → Prove → Measure. A finding leads to an authorized response. The system then checks what happened, preserves the evidence, and uses the result to inform the next decision.

The connection to Tesla is the use of observed behavior in assessing risk. VitalSec's design also focuses on the repair: what changed, whether it worked, and whether it lasted. The Ford Model provides the framework for studying the direction of residual cyber risk as those conditions change.

Monitoring and security services are already part of some cyber insurance offerings. [5,6] VitalSec is designed to keep the evidence connected from the first finding through the authorized action and the check afterward. We want to study that history with insurance partners.

From observation to an insurance decision
Tesla Insurance
The car records driving behavior. Safety Score gives drivers feedback and informs monthly premiums where that product is offered.
VitalSec
Observe the controls, authorize any needed action, check the result, and keep the evidence. Study how that history can inform security and insurance decisions.

Tesla already uses driving data in insurance pricing. The insurance use proposed for VitalSec requires testing its control history against loss outcomes.

5. What Changes When the Risk Is Cyber

Tesla collects data from vehicles it designs. A business runs a mix of devices, accounts, applications, and outside services from many vendors. Making sense of that evidence takes consistent definitions: what was observed, what the reading tells us, and what remains out of view. Good visibility into one device does not tell us how the whole business is protected.

Attackers adapt, and businesses depend on many of the same providers. A flaw in widely used software can affect many insured businesses at once. Insurers need to consider those shared exposures alongside improvements at an individual company.

The study also needs to be clear about the outcome it is trying to explain. Preventing an incident, limiting its spread, shortening an interruption, and reducing recovery costs are different results. Each matters, but they have different consequences for the business and its insurer.

6. From Operational Evidence to Insurance Use

Using this history to price insurance takes another step: testing how the measurements relate to actual incidents and losses. The Ford Model addresses risk direction. It is not a calibrated premium model. The work is to establish whether its measurements add useful information to what an insurer already knows.

A credible study starts with clear choices about the businesses being measured, the time period, and the outcome. Measurement definitions are set before the results are evaluated. The source, timing, coverage, and calculation version stay with each record so a reviewer can reconstruct what was known at the time.

Those observations then need to be linked to sufficiently complete incident or claims records. An empty incident log does not prove that nothing happened. Thousands of readings from one business do not count as thousands of independent businesses, either. Repeated observations and shared providers need to be accounted for in the study.

The model must then be tested on businesses or periods it was not built from, compared with simpler alternatives, and checked across different business types. Claiming that a repair caused an improvement takes additional work: the study has to account for why some businesses made that change and others did not.

The goal is to improve a specific decision: which loss-control work to prioritize, what changed at renewal, or how to estimate the frequency and cost of claims. Setting a premium also involves the coverage offered, expenses, capital, and applicable requirements.

7. A Practical Partnership Model

A sensible first project is a focused renewal study: does a documented history of controls and repairs make the review more useful? The partners would agree on the participating businesses, the systems and controls covered, the observation period, and what success looks like before starting.

The immediate aim is a clearer renewal submission and a better loss-control conversation. An underwriter needs to see what changed and which concerns remain. A broker needs records to support the client's account of the work. A pilot can test those uses while actuarial work examines the relationship to claims.

Each participant has a clear role. The business authorizes security activity and access to its evidence. The security provider documents what happened and what was repaired. The broker connects that history to the client's insurance needs. Actuaries and carriers assess its predictive value and decide whether it belongs in underwriting or pricing.

Data access belongs in that agreement from the start: which records are shared, who can use them, and how errors are corrected. A control history with supporting evidence may be enough for a particular review; access to every operational log should not be assumed. This gives a security platform a way to work with insurers without becoming the insurer itself.

8. Make Sustained Improvement Visible

Tesla's example is useful because it connects a measurement to something the driver can understand and act on. Cybersecurity needs that same connection. A business needs to know what requires attention, authorize the work, and see whether it helped.

A business that fixes problems and keeps its defenses working should have more to show for it than a completed checklist. PatientLock's thesis is that the evidence should follow the work: what changed, whether it held, and where gaps remain. That gives the business a record of its progress and gives insurers a concrete basis for studying how that progress relates to loss.
