Application Security Training • Updated Sep 2026
Core skills and competencies gained across our Application Security training programmes.
✓ Understand the principles of application security and how to build security into software from the design and development stages
✓ Identify common application vulnerabilities, attack surfaces, security weaknesses, and risks in modern software
✓ Apply OWASP Top 10 principles to identify, exploit, assess, and prevent common web application vulnerabilities
✓ Develop secure web applications using practical secure coding techniques and security controls
✓ Write more secure Python, Java, JavaScript, ASP.NET, and PHP applications
✓ Apply secure coding practices to authentication, input validation, access control, data handling, error handling, and other critical application security areas
✓ Identify and address security risks specific to Python applications used by data analysts, quantitative analysts, and data-focused teams
✓ Understand how insecure code and application vulnerabilities can be exploited and apply practical techniques to reduce attack risk
✓ Use practical security testing and attack simulation techniques to understand how applications may be targeted in real-world scenarios
✓ Build application security into development processes and create software that is more resilient against cyber attacks
Courses matched to your role, technology stack, and application security responsibilities.
Learn practical secure coding techniques for web applications and the languages you work with, including Java, JavaScript, Python, ASP.NET, and PHP. Identify common vulnerabilities and build security into applications from the start.
Understand the most common web application security risks and learn how to identify, exploit, and prevent vulnerabilities using practical techniques based on the OWASP Top 10.
Develop secure Python applications and understand security risks relevant to data analysts, quantitative analysts, and other professionals working with Python-based data and analytical environments.
Understand application security at the architecture and design level. Identify weaknesses early, establish appropriate security controls, and support development teams in building more resilient applications.
Strengthen practical application security capabilities through hands-on secure coding, vulnerability analysis, OWASP techniques, and cyber attack simulation.
Learn how vulnerabilities can be identified and exploited, understand application security testing approaches, and work more effectively with development teams to address security weaknesses.
Develop a practical understanding of application security risks and the techniques development teams can use to reduce vulnerabilities, improve secure coding practices, and build security into the software development lifecycle.
Whether you're a developer securing your own code, a data professional working with Python, a security specialist assessing applications, or a technical leader responsible for software security, this course group provides a practical learning pathway across secure web development, secure coding, Python security, OWASP Top 10, and cyber attack simulation.
For this section, I would not create new testimonials unless you have verified JBI testimonials specifically for these Application Security courses. It's better for SEO and trust to use genuine feedback from the individual course pages rather than generic invented quotes.
For example, the Java/JavaScript course currently includes delegate feedback describing the course as a useful security refresher with practical resources, and the OWASP course includes feedback about its practical and intermediate-level coverage.
You could structure the section like this once you have verified testimonials:
