What Makes us Different

What Makes us Different

We don't offer secure coding quizzes, that are effectively re-skinned multiple-choice questions.

If that's your idea of educating developers about software security, we are not the company for you.

Developers are who we serve. Adding artificial metrics, meaningless rewards and silly badges is not what we do.

We respect their time far too much to patronize them with these gimmicks.

The days of heavily scripted OWASP Top 10 training videos with robotic voice-overs are over.

Interactive storytelling with realness and purpose in short bursts is what put's developers in the middle of the action and drives a truly engaging learning experience.

Ludic Fallacy i.e. the misuse of games to model real-life situations is how we think of training labs.

Developers are more engaged in training if the content has a basis in reality rather than contrived examples.

No Labs & Flags
No code quiz No gamification No videos No labs and flags

Simply Beautiful

We set out to design the most beautiful application security training experience ever built. Backed by the same team that invented the first-ever interactive application security training platform for enterprise developers, we repeatedly pored over every pixel and design element to create a visually stunning and engaging learning experience.

Every minute detail, whether it be a simple tooltip to annotate vulnerable code blocks, or a complex user interface layout has been meticulously crafted from the ground up and relentlessly refined.

This website teaches with hands-on labs on most of the security vulnerabilities. I loved it. I recommend this for beginners/developers who wants to learn the basics of security

I've played around with application.securityand wonder: How could I live without this platform? The trainings are very interactive and full of details. Great job @security_contra !
