Abstract The tool that will be analysed in this article is the Threat Onboarding and Response (TOR) framework, which is an intelligent, automated enterprise cybersecurity tool. TOR incorporates threat onboarding, AI-assisted detection and automatic reaction to improve real-time monitoring, minimise the response time, and improve the resiliency of the cloud and the multi-tenant environment. The framework considers both the alert fatigue and the problem of tools fragmentation, along with human dependency, which also provides the defence that is proactive and scalable defence. Keywords: Threat Onboarding, Cybersecurity Automation, AI-Driven Detection, Enterprise Resilience
