Security training teaches hacking, not fixing — and the data shows the cost

Most hands-on cybersecurity platforms, including PortSwigger, Hack The Box, and TryHackMe, mark exercises complete once an exploit succeeds, with no requirement to understand or implement a fix. This offensive-first design was built for penetration testers but is now the primary training path for developers, students, and career changers whose actual job is to prevent attacks. A 2024 OpenSSF survey found nearly one-third of development professionals were unfamiliar with secure coding practices, with most relying on years of on-the-job experience to fill the gap. Secure Code Warrior's nine-year analysis found that developers trained in fix-oriented, secure-by-design methods introduced up to 53% fewer vulnerabilities, yet only around 4% of developers globally apply such practices. Meanwhile, Veracode and HackerOne data show security debt and unresolved vulnerability backlogs growing sharply, suggesting the industry is generating more findings than it can remediate.
