Front-end changes still trigger security rework or audit findings.
The situation this course is for
Even small UI updates can violate PCI DSS requirements if client-side storage, session handling, or error logging aren't designed with controls in mind. Developers often ship code that passes functional tests but fails security reviews, leading to rework, delays, and last-minute fire drills before audits.
Who this is for
Lead or senior front end developer in financial services, responsible for payment-adjacent interfaces and working across security and compliance teams.
Who this is not for
Junior developers learning HTML/CSS, back-end engineers focused solely on APIs, or compliance auditors without technical development experience.
What you walk away with
- Map front-end changes to PCI DSS control requirements before development begins
- Design secure UI patterns that pass security reviews without rework
- Speak confidently in joint engineering-security meetings with control-specific examples
- Contribute to internal compliance discussions with architectural solutions, not just questions
- Reduce friction between release velocity and audit readiness across teams
