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

LONDON - Jan. 16, 2026 - PRLog -- As cyber claims continue to rise in frequency and severity, insurers face a structural challenge: once data is exfiltrated, it can be copied, reused, and monetised indefinitely. Traditional security controls and incident response processes often fail to prevent the continued use of stolen data after a breach.

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 data has been copied or removed.

This approach has direct implications for cyber insurance underwriting and claims management. By neutralising stolen data, insurers may reduce downstream losses associated with extortion, regulatory exposure, customer remediation, and long-tail liability. The technology generates audit-ready evidence demonstrating that stolen data was rendered non-reusable, supporting underwriting differentiation and claims assessment.

The model aligns with ongoing discussions within the cyber insurance market, including at Lloyd's of London, as insurers and reinsurers seek measurable loss-containment mechanisms beyond breach response.
