In today's fast-paced digital world, balancing rapid deployment with robust security measures is crucial due to the increasing reliance on digital platforms and the growing threat of cyberattacks. Secure code development best practices, including integrating security testing early in the software development lifecycle, using secure coding guidelines and standards, and leveraging tools like static and dynamic code analysis, are essential for achieving this balance. By adopting a holistic approach to security, developers can create software that is not only secure but also robust and reliable, capable of withstanding both current and emerging threats. Tools like New Relic provide integrated observability and security capabilities, empowering teams to uphold the principles of shift left and deliver secure, high-quality software at speed.
