Frequently Asked Questions

Yes, the diagnosis, quotation, and sample data recovery up to 1GB are completely free. We will verify if your sample files can be recovered and present the sample result along with a quotation beforehand. You can decide whether to sign a formal contract after reviewing these. No costs are incurred prior to signing.

During the initial diagnosis, we will agree with you on the target critical data (e.g., folders or specific extensions). If the recovery rate of these target data is less than 80% after the final operation, we will refund the operation fee in full. This SLA (Service Level Agreement) is explicitly stated in the contract.

No, we do not contact or negotiate with attackers, nor do we facilitate ransom payments using cryptocurrency. Our service uses a purely technical approach to reconstruct and restore encrypted files from their structure. This prevents funding attackers and ensures compliant data recovery.

We enforce extremely strict confidentiality. We do not upload or transfer your data to external cloud services or overseas servers. All data analysis is completed entirely within our secure on-premise environment in Japan or via secure private networks. All data is completely deleted upon completion. We can sign an NDA (Non-Disclosure Agreement) before starting the diagnosis.

We support a wide range of ransomware encryption patterns, including major ones like LockBit, Akira, Qilin, and BrainCipher. While ransomware is constantly evolving, our technology reconstructs files based on structural damage rather than relying on static decryptors, yielding a high success rate across various families. We verify recoverability for free during the diagnosis.

Generally, we perform operations remotely or by shipping storage media to our secure facility. However, for systems in financial or government organizations where data removal is strictly prohibited, we can dispatch engineers for on-site diagnosis and recovery upon consultation.
