Long-tail liability lines hold policyholder data for decades. The harvest-now, decrypt-later threat means data encrypted today with classical algorithms may be readable by quantum computers well within those retention periods. This workshop addresses the specific intersection of insurance data retention obligations and quantum cryptographic risk.
Professional indemnity claims can be reported up to 15 years after the insured event. Medical malpractice and environmental liability policies routinely hold data for 25 to 40+ years. Directors and officers coverage generates sensitive financial disclosures that must be retained across multiple syndicate years. All of this data is encrypted with algorithms that a sufficiently capable quantum computer could break.
The harvest-now, decrypt-later (HNDL) threat model applies acutely to these long-tail lines. An adversary intercepting encrypted policyholder data today does not need to decrypt it immediately. They need only store it until quantum decryption capability becomes available. For data with a 30-year retention obligation, even optimistic quantum timelines fall well within the exposure window.
This workshop works through the specific problem of quantum cryptographic risk to long-duration liability data. Participants classify their data holdings by sensitivity and retention period, map cryptographic dependencies against quantum capability timelines, assess regulatory obligations under GDPR, Solvency II, and PRA requirements, and develop practical re-encryption strategies prioritised by risk exposure rather than data volume.
Full Day Workshop structure with scheduled breaks. Content is configurable to your organisation's specific liability lines, data retention policies, and regulatory jurisdiction.

Workshops are designed and delivered by QSECDEF in collaboration with sector specialists. All facilitators have direct experience in both quantum security and insurance data governance.
Workshop design and delivery
QSECDEF brings world-leading expertise in post-quantum cryptography, quantum computing strategy, and defence-grade security assessment. Our advisory membership spans 600+ organisations and 1,200+ professionals working at the intersection of quantum technologies and critical infrastructure security.
Domain expertise and operational validation
Insurance workshops are co-delivered with sector specialists who bring direct operational experience in insurance data governance, long-tail liability management, and regulatory compliance. This ensures workshop content is grounded in the realities of multi-decade data retention and the specific regulatory frameworks governing insurance organisations.
Sessions are configured around your organisation's specific liability lines, data retention policies, and regulatory jurisdiction. Get in touch to discuss requirements and schedule a date.
