Hey folks, I recently launched a software development startup with two technical co-founders. While they focus on the development work, I’m handling business operations and trying to understand why so many companies struggle with building secure applications from day one. I keep hearing about security-first development principles, but it seems like most organizations still treat security as an afterthought rather than a core requirement. What are the main barriers that prevent teams from integrating security measures right from the beginning of their projects? Is it budget constraints, tight deadlines, lack of expertise, or something else entirely? I’m curious to hear from developers, team leads, security specialists, and anyone else who has dealt with this challenge. Not trying to pitch anything here, just genuinely want to understand this problem better.
