Chef Secure's Ultimate XSS Training Course specializes in making sure students and engineering teams understand XSS attacks, exploits, defenses and prevention strategies through practical experience-based learning.

Why learn hacking?


Simply put — cybercriminals can't be stopped if their attacks aren't fully understood.

Built-in protections are no longer enough to stop XSS on the web.

Students and engineers need hands-on experience working with the latest attacks and defenses in order to stay ahead of today's attackers.


This course teaches how to:

Discover critical XSS vulnerabilities in web applications.

Analyze and stop malicious exploits from criminal hackers.

Fix XSS vulnerabilities with tactical precision, total accuracy and swift urgency.

Secure applications with proactive defenses that stop vulnerabilities before reaching production.

Our secret ingredients

  • Entertaining and educational recipes instead of endless slide decks and wikis
  • Hands-on challenges and experience instead of quizzes and cramming
  • Follow-along examples instead of passive, unengaging lectures
  • Modern technologies instead of outdated, historical facts
  • Daily work environments instead of complicated overhead
  • Real-world skills instead of useless badges, trophies and points

XSS Training Value


BOTTOM LINE: Fixing XSS vulnerabilities costs more than the full price of this course.

MAKING THE CASE

A single XSS vulnerability report is often awarded over $1,000, growing with severity and impact. For instance, Google awards $7,500 and Yahoo has paid $10,000 for a single XSS vulnerability report.

Next comes the total cost of the vulnerability's lifecycle:

  1. Receive report
  2. Validate issue
  3. Create ticket for developer
  4. Setup development environment
  5. Find flaw in code
  6. Write fix
  7. Pass QA tests
  8. Release patch
  9. Verify fix with researcher (repeat if not fixed)
  10. Issue reward
  11. Coordinate disclosure details

To make matters worse, the cost of an XSS vulnerability grows exponentially when its exploited and causes damages with legal consequences, ruined brand reputation and loss of customers.


This course automatically pays for itself when you find, fix or learn to prevent just
ONE XSS vulnerability
