We have established an ecosystem called “ASTIRA,” aimed at continuously updating security activities throughout the entire product lifecycle. We integrate the data and analysis results obtained from ASTIRA into each phase of the product lifecycle to enhance product security. As a case study, we would like to introduce “VERZEUSE™ for SIRT.” This solution analyzes the security risks of in-vehicle software vulnerabilities discovered after the shipment, and determines the priority for addressing them. Our goal is to reduce the time required for risk analysis and vulnerability remediation.
