Why this program matters
Without advanced DKIM mastery, 85% of companies suffer monthly email spoofing, leading to blacklists at Gmail and Outlook that block 40% of legitimate messages.
This results in estimated client losses of 250k€ annually per successful phishing attack, according to the Verizon DBIR 2023 report, and career risks for IT pros with 30% of promotions missed due to lack of cybersecurity skills.
Your company loses reputation, with GDPR compliance threatened by fines up to 4% of revenue.
Invest now in training to secure your email flows and boost deliverability.

Our method
Training quality, guaranteed at every step
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.
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.
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.
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.
