Privacy-class-action exposure tripled in two years. The cyber insurance market itself has paid out more in cumulative ransomware-driven loss than any other line. PULSE engineers infrastructure in which the insurer-held data that drives that loss curve cannot be disclosed by an adversary that has already breached the perimeter.
Insurance occupies an unusual position in the cybersecurity landscape. It is simultaneously a regulated financial-services industry that holds vast volumes of personally identifiable information, protected health information, and financial data — and the industry that insures the rest of the economy against the consequences of the same breaches it must defend against. The exposure is doubled.
Munich Re's 2024 cyber analysis identified manufacturing as the industry with the highest absolute number of ransomware claims, but found that the cost of privacy-class-action claims in the insurance and financial sectors has tripled in value over two years. The proximate driver is the wave of US class-action litigation related to wrongful collection and processing of personal data, with breach disclosures triggering hyper-litigation: more than 240 lawsuits related to the 2023 MOVEit campaign were consolidated into a single multi-district proceeding.

The data held by insurers — health-condition records, financial-disclosure forms, claim histories, beneficiary identities, biometric data for KYC — is precisely the data that produces the highest individual-victim impact when breached. It is data that cannot be re-issued. A leaked credit-card number can be replaced in days. A leaked record of a beneficiary structure cannot be unleaked.
The same threat actors target insurance and banking, but the data they extract — and the regulatory consequence of that extraction — diverges materially. Insurance-sector defence has lagged banking-sector defence by approximately a regulatory cycle.
The Cl0p mass exploitation of MOVEit Transfer in 2023 catalogued insurers including Sun Life US, Transamerica, Vitality Group, TIAA-CREF, and dozens of others as victims through their service providers — the National Student Clearinghouse, PBI Research Services, Westat, and others. The insurer was the data custodian; the breach happened upstream.
Insurance and health-plan websites have been heavily targeted for class actions alleging unlawful tracking-pixel transmission of user behaviour to third parties (Meta Pixel, Google Analytics, X). The Office for Civil Rights vacated some guidance in 2024 after a successful legal challenge, but the litigation cost remains.
Modern ransomware operators encrypt operational data, exfiltrate sensitive customer data, threaten regulatory disclosure, contact individual claimants, and short the public stock — frequently in sequence. The Resilience 2025 claims data showed average healthcare-related ransomware loss has risen from USD 705,000 (2024) to a projected USD 2 million (2025).
IBM's 2024 study identified malicious insider attacks as the highest-cost initial vector, averaging USD 4.99M per breach. Insurers, with concentrated PII access among adjusters, underwriters, and claims teams, are structurally exposed. Privileged misuse is now reported separately by Verizon as a distinct category, reflecting its severity.
Insurance breaches now have a structurally longer cost tail than banking breaches. The incident itself triggers regulator notification, customer notification, and — increasingly — class-action filings within weeks. Allianz Commercial reports that data-and-privacy-breach-related elements were present in two-thirds of large cyber claim losses in the first half of 2024. The insurer pays the breach response. Then the insurer pays the litigation. Then the insurer pays the regulatory fine. [02]
The applicable regulatory frameworks compound. HIPAA imposes a 60-day breach notification requirement for HIPAA-regulated insurers (most US health plans). State insurance regulators impose parallel notification regimes (NAIC Insurance Data Security Model Law, adopted by 21+ states). The EU GDPR imposes a 72-hour notification requirement and individual consumer rights including data portability and erasure. Australia's Privacy Act 1988 (as amended by the Privacy Legislation Amendment (Enforcement and Other Measures) Act 2022) imposes penalties of up to AUD 50 million per breach for serious or repeated interference with privacy.
None of these regimes provide a defensive credit for an architecture in which the breach cannot result in disclosure of personal data. They all contemplate the breach having already produced disclosure.
The insurance industry insures itself against losses produced by an architecture it knows is structurally indefensible. The premium is the institution's acknowledgement that the architecture cannot hold.
The single most expensive component of an insurer's cybersecurity posture is the residual loss the insurer carries in the event of a breach that proceeds despite controls. That residual loss includes regulatory fines, class-action settlements, customer notification cost, credit monitoring obligations, business interruption, share-price impact, and reputational damage. The proximate cause of all of these is the same: the data the adversary came for was disclosed.
In a PULSE-substrate environment, the principal targets of insurance-sector attack are rendered architecturally impossible to disclose. Customer PII, beneficiary structures, claim histories, and biometric KYC data are made unavailable to any party — including the insurer's own infrastructure operator, including the cloud-platform host, including us — that does not hold the specific authorisation to access that specific record at that specific moment.
This is not strong access control. It is not stronger encryption-at-rest. It is a different architectural position. The means is the trade secret. We disclose it under executed NDA only.
