In Japan, application security refers to the measures, practices, and tools used to protect software applications from external threats throughout their entire lifecycle. This includes the identification, repair, and prevention of security vulnerabilities within web, mobile, and cloud-based applications. Key characteristics of the Japanese market include a high demand for premium reliability and a shift toward automated testing solutions like static application security testing (SAST) and dynamic application security testing (DAST). Current trends show a significant move toward DevSecOps, where security is integrated directly into the DevOps workflow to ensure rapid yet secure software delivery.
