We have established criteria to help service developers appropriately design the system architecture and choose the right technologies. These criteria are intended to achieve the following:
By reducing the time spent on technology selection and avoiding the reinvention of the wheel, we aim to streamline the development process and strengthen our competitive edge.
We optimize costs by appropriately designing our internal operational systems for handling vulnerabilities, managing technology lifecycles, and other issues.
We mitigate security risks by ensuring that developers receive support from our company-wide initiatives such as detecting vulnerabilities and formulating policies to handle them.
We work to prevent know-how from ending up in the hands of only a few individuals.
