The claim is verifiable.The insurer sees no logs.

A cyber incident can be proven and its loss quantified without the insurer ever receiving the underlying records.

Launch platformSchedule demo

Insurance runs on trust.

Lenders check the history. Motor insurers check the driving.Cyber insurance still checks the form.

Both sides pay for that gap.

of US cyber insurance claims closed in 2024 ended without a payment.

Who pays for the gap

Insurer pays

  • To verify, not to protect: a forensic investigation decides whether it is liable at all.
  • For what it cannot see: an incident is easy to stage, and the evidence cannot show who made it.
  • In court: one insurer funded a $4.125M settlement, then sued to take it back.

Policyholder pays

  • Up front: the investigation that proves the claim can be required, and paid for, before the claim is filed.
  • At the worst moment: a control ticked on the form and found missing after the loss can void the policy from the start.

Why the usual fixes fall short

The questionnaire

Records that a control was bought, not that it works.

Outside-in scoring

Sees the perimeter, not the controls inside it.

Controls as conditions

Moves the question to the claim instead of checking it.

Forensic review

Answers after the loss, once it is a dispute.

Collecting the data

Needs the very records the company insured.

How a claim is settled on evidence

The same move, without the data changing hands.Five steps. Each one can be inspected.

What the platform does

Real-time underwriting

Underwriting built into your stack. The insurer sees the result, not the data.

Security dashboard

Visual risk assessment drawn from the security systems you already run, updated as things change.

Incidents detection

Real-time incident signals from the security systems you already run.

pub fn verify_claim_proof(    pvk: &PreparedVerifyingKey<Bls12_381>,    proof: &Proof<Bls12_381>,    public_inputs: &[Fr],) -> bool {

Claims verification

Insurers receive a result backed by cryptographic proof rather than by an account of what happened.

Settlement handoff

The output is a verified claim with a quantified loss, handed to the insurer's existing settlement process.

01 / ONBOARD

Underwriting from what is already running

Watch Guardian connects to the policyholder's existing security systems and assesses exposure in place.

02 / DETECT

The incident is recorded where it happens

When an incident occurs, it is captured in real time from the signals the policyholder's security systems already produce.

03 / ASSESS

What it cost, from the same evidence

The signals that establish the incident are also used to quantify the loss it caused.

04 / PROVE

A proof instead of a submission

The policyholder generates a signed, verifiable proof that the incident occurred and what it cost.

05 / VERIFY

Checked, not believed

The insurer verifies the proof. Acceptance rests on a mathematical result rather than on a judgement about the policyholder's account.

What the pilot proves

  • Events are signed at the source

    Watch Guardian signs every event it reads.

  • Tampering breaks the proof

    A forged, deleted or inserted event fails verification.

  • The insurer gets only the proof

    Logs, tickets and forensic reports never reach the insurer.

No fee. Four things agreed up front.

Owner
Someone at the insurer who owns the pilot and can approve the next step.
Criteria
What counts as a pass, in writing, before day 1.
If it passes
The next step is agreed before day 1, so a good result does not stall.
Reference
Anonymised by default; your name only if you agree.

All four are agreed on one scoping call, before anything is installed.

Frequently asked questions

What is Protectorium?

Infrastructure for cyber insurance claims. It records an incident inside the policyholder's environment, quantifies the loss, and produces a proof the insurer can verify without receiving the underlying evidence.

What is a zero-knowledge proof, and why use one?

A zero-knowledge proof establishes that a statement is true without revealing the information the statement is about. In a claim, it lets a policyholder demonstrate that an incident occurred and what it cost while the records that show it never reach the insurer.

How do you prevent fraud?

A claim is only accepted if it comes with a proof that verifies. There is no path that accepts a claim on description alone.

How is confidentiality maintained?

Watch Guardian signs security events where they happen and sends them to Protectorium, which builds the proof and keeps no logs. The insurer receives the proof and the assessed amount, never the records, so it never has custody of them.

Is this an AI judgement?

No. Verification is a check, not an opinion. It either passes or it does not, and the result does not depend on who is reading it.

How long does verification take?

Verification is an automatic check rather than an investigation, so it does not wait on scheduling, correspondence, or a forensic report.
