Fraud-Proof Cyber Insurance

Protectorium is an InsurTech platform that streamlines interactions between Insurers and Policyholders in the cyber insurance industry. It enables Policyholders to prove the occurrence of an insured event (such as a cyberattack or data breach) without disclosing confidential corporate data. At the same time, insurers receive mathematically verifiable proof based on Zero-Knowledge (ZK) Cryptography, eliminating fraud risks and accelerating claims verification. 

 Zero-Knowledge proofs (ZK proofs) are a cryptographic method that allows one party to prove the validity of secret data without revealing it. In the context of cyber insurance, this means that a policyholder can confirm an incident (such as a data breach) without compromising sensitive corporate information. ZK cryptography is already widely used in blockchain applications (e.g., Ethereum’s ZK-rollups) and authentication systems, where users can verify their identity without sharing passwords. 

Protectorium helps insurance companies prevent fraud through the strict system assumptions of its cryptographic ZK protocol. It is impossible to forge proof or manipulate the system because a ZK proof is generated only when all insurance policy conditions are met. If the data does not confirm the insured event, the proof simply cannot be created. This prevents any form of manipulation and ensures an objective claims verification process. 

Protectorium guarantees data confidentiality by ensuring that the Insurer receives only a ZK proof, not the raw data itself. Additionally, the Insurer can independently verify the proof’s validity using the Protectorium cryptographic protocol without relying on third-party systems. Protectorium does not store or transmit any raw data — data is only used as input parameters within the ZK circuit, eliminating any risk of exposure.

Protectorium significantly accelerates claims verification, reducing processing times from weeks to minutes. A ZK proof can be automatically verified by the Insurer within our cryptographic protocol in just a few minutes. Once verification is complete, both parties can immediately proceed with damage assessment and payout agreements — without lengthy investigations or excessive paperwork.

Protectorium unlocks new opportunities for Insurers by enabling them to cover organizations dealing with highly confidential data — companies that previously avoided commercial insurance due to the risk of data exposure. Now, entities such as government agencies, financial institutions, and high-tech enterprises can access cyber insurance without compromising their data, even during claims verification. This expands Insurers’ client base and opens up new market segments.

For Policyholders, Protectorium ensures unique, fast and secure claims resolution without the risk of data leaks. There is no longer a need to grant Insurers access to internal IT infrastructure or disclose sensitive information to prove losses. What previously took months can now be resolved in days, making payouts predictable and protected from subjective Insurer decisions.
