Allianz: Ransomware still top cyber-risk as supply chain threats grow

New research from Allianz has confirmed that ransomware continues to dominate as the leading cause of large cyber insurance claims, even as the severity of incidents has declined.

 

The insurer’s 2025 risk trends analysis found that while claim frequency has dropped, ransomware still accounts for the majority of losses above €1 million.

Improvements in detection and response have helped reduce average costs, but the report warns that new risks are emerging.

 

Supply chain vulnerabilities, social engineering attacks, and regulatory exposures are becoming increasingly significant.

 

Organisations without dedicated cyber insurance remain disproportionately exposed, with smaller businesses especially vulnerable due to limited in-house expertise.

 

The report also highlights the persistence of the cyber skills gap as a major weakness.

 

Without adequate investment in skilled professionals, companies risk falling behind adversaries that continue to adapt and evolve.
