A tailored course, built for your situation
Sources and specific examples on hand when peers push back on OWASP
Build defensible OWASP implementation logic rooted in real-world precedents and auditable reasoning
The situation this course is for
Technical leads in payments modernization are increasingly expected to justify OWASP alignment decisions to cross-functional reviewers. Without documented rationales or specific examples, decisions appear subjective, even when they’re sound. This creates rework, delays in sign-off, and erosion of credibility, especially when peer reviewers lack context but demand justification.
Who this is for
Senior technical compliance lead in financial services, implementing secure payment transformation with ISO 20022 and modern security frameworks
Who this is not for
Entry-level developers, auditors looking for checklists, or consultants selling generic OWASP training
What you walk away with
- A personal library of OWASP control rationales with citations from real implementations
- Ability to explain control selection using specific examples from PCI DSS-aligned deployments
- Documented patterns for handling OWASP in ISO 20022 message validation layers
- Response-ready reasoning for common pushbacks (e.g., 'This control slows deployment')
- Clear linkage between OWASP, NIST 800-53, and payment security architecture
