PastWipe Introduces Post-Breach Data Neutralisation to Reduce Cyber Loss Severity for Insurers and Reinsurers

PastWipe, a privacy-infrastructure company focused on post-breach data control, has announced the availability of its post-exfiltration data neutralisation technology designed to reduce the financial and operational impact of cyber incidents for insurers and reinsurers.

As cyber claims continue to rise in frequency and severity, insurers face a persistent structural challenge: once data has been exfiltrated, it can be copied, reused, and monetised indefinitely. Traditional security controls, contractual remedies, and incident response processes often fail to prevent the continued use of stolen data after a breach has occurred.

PastWipe addresses this gap by enabling organisations to render exfiltrated data unusable after it has left their systems. Rather than attempting to prevent every breach, the technology focuses on limiting loss severity by cryptographically enforcing post-breach restrictions at the data level, preventing unauthorised reuse even when files have been copied or removed.

The approach has direct implications for cyber insurance underwriting and claims management. By neutralising stolen data, insurers may be able to reduce downstream losses associated with extortion, regulatory exposure, customer remediation, and long-tail liability.

"Cyber insurance has become increasingly difficult to price because loss exposure does not end when systems are restored," said a spokesperson for PastWipe. "Our objective is not to replace preventative security controls, but to give insurers and reinsurers a mechanism that materially limits post-incident damage."

The technology has been designed with insurance and reinsurance stakeholders in mind, including the ability to generate audit-ready evidence that demonstrates how stolen data was rendered non-reusable following a breach. This capability may support underwriting differentiation, claims assessment, and future policy incentives tied to post-breach controls.

PastWipe's model aligns with emerging discussions within the cyber insurance market, including at Lloyd's of London, where underwriters and managing agents have highlighted the need for new approaches to managing systemic cyber risk and loss accumulation.

While not currently mandated by insurers, post-breach data neutralisation is being evaluated as a potential complement to existing security requirements, particularly for organisations operating in high-risk sectors such as financial services, healthcare, critical infrastructure, and professional services.

PastWipe notes growing interest from both primary insurers and reinsurers, including global market participants such as Swiss Re and Munich Re, as the industry explores tools that move cyber insurance beyond breach response toward measurable loss containment.

The company's technology is protected by patent filings covering post-exfiltration data control and enforcement mechanisms and is designed to integrate with existing enterprise and cloud environments without replacing current security stacks.

As cyber risk continues to evolve, PastWipe positions post-breach data neutralisation as a missing infrastructure layer-one that enables insurers and reinsurers to address not only the likelihood of cyber incidents, but their long-term financial consequences.
