Security Dev Training

Build secure software from day one

Teach developers how real attacks work, how vulnerabilities happen, and how to prevent them, without slowing down delivery

Tailored to your stack, maturity, and risk profile.

Developers are on the front line, whether they asked to be or not

Most breaches do not happen because someone forgot to care. They happen because the secure way was not clear, not taught, or not built into daily habits. Our hands-on training focuses on the vulnerabilities attackers actually exploit, broken access control, injection, auth mistakes, insecure design, weak secrets handling, and insecure dependencies, and shows how to spot and fix them properly.

What we cover

The vulnerabilities attackers actually exploit

OWASP Top 10 and beyond

Secure coding fundamentals, threat modelling basics, and the risks that matter for your stack.

Auth and secrets
