What prevents companies from adopting security-first approaches during software development?

Hey there,

I recently launched a software startup with a couple of technical co-founders. While they focus on 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 wondering about this:

Why do most organizations still treat security as an afterthought instead of building it into their development process from the beginning?

What are the main barriers that prevent teams from implementing security-first methodologies? Are we talking about budget constraints, tight deadlines, lack of expertise, or maybe the complexity of modern tech stacks?

I’d really appreciate hearing from anyone who has experience with this - developers, technical leads, security specialists, or business folks like me.

Just trying to understand the landscape better, not promoting anything. Thanks for sharing your thoughts!

Interesting question! I’m curious - do dev teams push back when you introduce security practices? Like, do they see it as killing their workflow or creativity? Is the resistance more about technical stuff or just mindset in your experience?

honestly, it’s mostly about money and deadlines in my experience. management always says “we’ll fix security later” but later never comes. developers don’t want to slow down their coding flow with extra security steps either - they just want to ship features fast.

From what I’ve seen in enterprise environments, the biggest hurdle isn’t technical - it’s organizational inertia. Companies get stuck in their established workflows where security reviews happen at fixed checkpoints, usually way too late in development. You can’t just change the process either. You need to restructure budgets and team responsibilities too. The skills gap is huge. Most developers get almost zero security training in school, so they honestly don’t know how to write secure code. Hiring dedicated security engineers costs a fortune, and lots of companies think they can just rely on automated scanning tools. Time pressure makes everything worse. When leadership pushes for faster delivery, security gets thrown out first because stakeholders focused on features and revenue can’t see the immediate benefits.
