Strengthening Vehicle Cybersecurity and Compliance at Scale

As vehicles become increasingly connected and software-centric, managing vulnerabilities and demonstrating cybersecurity compliance are top priorities for automotive system suppliers. For a global leader in automotive mechatronics and safety-critical components, the challenge was to establish a scalable and structured way to manage vulnerability detection, remediation workflows, and regulatory compliance across a vast product portfolio. Manual processes and fragmented tooling made it difficult to maintain consistent visibility into emerging vulnerabilities and to generate audit-ready evidence for frameworks such as ISO/SAE 21434. The supplier required a standardized, repeatable approach that could operate continuously across distributed teams and evolving software environments.

To address this, the company selected the PlaxidityX cybersecurity platform to embed continuous vulnerability management and compliance support into its engineering lifecycle. Built on Amazon Web Services (AWS), the platform leverages AWS Lambda and Step Functions to automate vulnerability and compliance workflows, while Amazon SQS enables event-driven processing across distributed development environments.

The architecture utilizes Amazon RDS Proxy to manage secure, high-availability connections to managed data stores, ensuring that all vulnerability data remains traceable and consistent. Furthermore, the use of Amazon API Gateway as a hardened entry point, combined with Amazon S3 for secure artifact storage, ensures that centralized data handling is both scalable and audit-ready. By transforming cybersecurity into a scalable operational capability, the platform supports continuous vulnerability management across complex automotive systems while maintaining the high standards of safety-critical engineering.
