Expert Tip

DevSecOps not only accelerates software development, but also significantly reduces the costs of remediating security issues. Studies show that fixing security vulnerabilities in the production phase can cost up to 100 times more than addressing them during the development phase. By integrating security into early development phases, organizations can not only improve security quality but also achieve substantial cost savings.
