New Frontend Security Course Released On Learn

The 2018 British Airways “Magecart” breach injected malicious JavaScript into payment pages, capturing credit card details for hundreds of thousands of customers and resulting in a proposed £183.39 million GDPR fine — a landmark moment for frontend security risk and regulatory exposure.

Modern frontends now run a huge share of application logic. They parse untrusted data, execute third-party scripts, and handle authentication tokens — all inside the user’s browser. When that surface goes wrong, the blast radius is enormous.

Browsers and frameworks have added strong guardrails such as Content Security Policy (CSP), Trusted Types, SameSite cookies, and Subresource Integrity (SRI).

Our new Frontend Security course covers how modern frontend attacks work and how to properly apply these defenses in real-world applications using layered security approaches.
