Why this program matters

  • Without mastery of gray-box testing, 40% of critical software vulnerabilities go undetected despite exhaustive black-box tests.

  • Each defect found in production costs an average of 100 000 € to fix, with timelines multiplied by 10 and a 30% productivity loss for development teams.

  • These gaps expose the company to massive data breaches, revenue losses up to 25%, and GDPR penalties reaching 4% of annual revenue.

  • Every month without optimizing software qualification amplifies these risks, jeopardizing competitiveness and the careers of QA managers.

Our method

How Learni guarantees the quality of your Gray Box Testing training

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.

  • Live briefing on goals and team context.
  • 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.

  • Hands-on cases drawn from your stack and 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.
