Equally important is our strategy of "sanitizing" every element that interacts with production environments or client data. Every unvetted user or device is a potential entry point for attackers. Before individuals, systems, or tools are permitted to operate in real-world environments, they must undergo appropriate validation and readiness checks. For people, this includes awareness, training, policy acknowledgment, and access governance. For machines, it involves security assessments, configuration reviews, vulnerability management, and compliance validation. For tools and technologies, including emerging AI and automation platforms, it requires rigorous evaluation of security, privacy, contractual, and operational risks before deployment.
