As Web services and cloud adoption continue to expand, the number of SSL/TLS certificates that need to be managed keeps increasing. At the same time, the so-called "47-day certificate problem"—where certificate validity is reduced to 47 days—is becoming increasingly realistic, and manual operations are reaching their limit. Manual renewal mistakes can directly trigger major incidents such as service outages. Even if organizations automate only the "renewal process," issues remain around secret key handling and audit compliance, so a state where teams can safely and fully entrust operations is still not achieved. ■ Barriers to automation: the security and operations dilemma Even when companies try to automate certificate management, they often face common obstacles that slow or block adoption: 1. No clear standards: unclear requirements for secret key storage, access control, and audit logging. 2. Cross-department silos: IT infrastructure, security, operations, and development teams have different priorities, making alignment difficult. 3. Operational complexity: as the number of target servers grows and exception handling accumulates, operations fail to scale as expected, even with automation. ■ From storage to deployment: toward next-generation operations that balance robustness and speed This seminar explains how to overcome the 47-day certificate problem and eliminate issues caused by individual ownership and audit constraints. Beyond renewal alone, it introduces a "zero-touch" operation approach that combines Vault for key management and Ansible for configuration management, enabling end-to-end control from centralized management to deployment. A dedicated engineer will provide practical guidance on how to design operations that can be adopted across departments with internal alignment and sustained execution. ■ Recommended for participants who: ・In IT infrastructure or operations roles and feel that certificate renewal and management are becoming too dependent
