Kontra + Courses helps organizations build application security skills across development teams through a combination of 50+ video courses and 300+ hands-on vulnerability labs. Developers learn to identify, exploit, and remediate real vulnerabilities across 25+ technology stacks using practical code examples in their actual frameworks. Each Kontra lab walks through a real-world vulnerability scenario—like the 2021 Log4Shell exploit—then guides users through hands-on remediation with stack-specific code. This practical approach leads to 3x higher completion rates than traditional security training and helps AppSec teams scale secure coding practices without pulling developers out of their workflow. Most labs take under 10 minutes to complete. The platform is SCORM-compliant and integrates with existing LMS systems or can be delivered via hosted environment. Role-based curriculum aligns with NIST, ISO 27001, and PCI-DSS, and supports ISC2 co-branded certification.

Code Review Lab is a hands-on secure coding and code review training platform designed to help developers, security engineers, and DevSecOps teams identify, understand, and fix real-world vulnerabilities before they reach production. Rather than relying on passive learning such as videos or slides, Code Review Lab immerses users in realistic code review scenarios where they analyze vulnerable code, spot security flaws, and apply secure fixes. The platform focuses on practical, job-relevant skills and mirrors the challenges engineers face in real development environments. Code Review Lab supports multiple programming languages and covers a wide range of application security topics, including common vulnerability classes, secure coding best practices, and real-world attack patterns. Interactive exercises provide immediate feedback, reinforcing a security-first mindset and helping teams continuously improve their secure coding capabilities.
