Secure by Design is an approach to developing software, hardware, or systems where security is a core consideration from the very beginning. Instead of adding security features later, designers and engineers integrate protections into every stage of planning, development, and deployment. This proactive strategy helps prevent vulnerabilities, reduces risks, and ensures that security is not overlooked. By making security a foundational element, Secure by Design helps create more resilient and trustworthy products that are better equipped to withstand cyber threats.
