Why this program matters

  • Without control over environment variables, 80% of web application data breaches stem from configuration errors, such as the accidental exposure of API keys in source code.

  • Such a leak costs a company an average of 4.5 million euros per incident, with weeks of downtime and GDPR fines that can reach 20 million euros.

  • Your career and your team's careers are at stake: a breach exposes the company to irreversible losses of customers and trust.

  • Every month without securing the system worsens the vulnerabilities, multiplying the risks by 3.
