Why this program matters

  • Without mastery of OAuth2, 70 % of web applications and APIs remain exposed to critical authentication vulnerabilities, as shown in the OWASP Top 10 report.

  • Each breach from poor implementation costs a company an average of 4,2 millions d'euros, plus 250 hours of development lost to emergency fixes.

  • Your team racks up project delays, GDPR fines up to 4 % of revenue, and customer losses—a direct threat to reputation and business survival.

  • Every month without solid OAuth2 skills worsens these vulnerabilities, directly endangering your career and the company's competitiveness.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
