Our company is a rare entity in Taiwan with extensive experience in decryption. Our extensive case analysis reveals that errors in enterprise software, hardware, and network configurations can lead to significant losses after hackers encrypt files and make them indecryptable. We provide a system configuration health check service to identify security vulnerabilities and potential vulnerabilities. By leveraging our experience with common methods used by various hacker families, we provide clear and detailed improvement plans. This service reduces the risk of data being irrecoverable in the event of a digital disaster. We also conduct ransomware scoring health checks to effectively reduce the risk of data being irrecoverable in the event of a ransomware attack.
