Hello from The Secure Cookie
An introduction to me and to this newsletter. And why secure coding is more than just following AI hints.
Curiosity, learning, and hands-on testing are what brought us here today, to this exchange between writer and reader. Knowledge has always been the fuel behind human progress.
Right now, AI is reshaping almost everything we do—especially the way we code. Developers used to spend hours digging, testing, and figuring things out. Now we often just ask. That makes us faster and more productive, but when it comes to complex areas like security, things aren’t that simple. Security touches everything: system performance, application usability, data integrity, user privacy, etc.
The truth is, you can’t build secure systems without really understanding security. If you don’t know the threats, you can’t pick the right defenses. AI can give useful hints, but without the right context, you might not apply them correctly—and that’s when trouble happens.
These days, people assume applications need to be secure by default. Teams expect developers to deliver features quickly, meet business requirements, and avoid security gaps—all at once.
That’s why knowledge is still such a powerful advantage. AI is great, but understanding gives you perspective. It helps you learn faster, solve harder problems, and work smarter.
For me, secure coding isn’t just about following best practices or plugging in AI suggestions. It’s about being ready for tough situations, really knowing the technology, and enjoying the process.
That’s what motivates me to write this newsletter: to share what I’ve researched, tested, and learned in terms of secure coding—hopefully in a way that makes life a little easier for developers.
I hope you find it useful.
