Case Study: OpenClassrooms protects its platform and enables secure remote access with Cloudflare

OpenClassrooms mitigates 99% of attacks with Cloudflare

OpenClassrooms, an online school serving over 300,000 monthly users worldwide, faced the dual challenges of securing its platform against increasing attacks and supporting its rapid growth without compromising performance or user access. To address these needs, they turned to vendor Cloudflare for security and performance solutions, including DDoS mitigation, a Web Application Firewall (WAF), and later, the Cloudflare Access service for Zero Trust Network Access.

The solution from Cloudflare involved protecting the platform's infrastructure globally, mitigating 99% of attacks, such as blocking 12 million security alerts in one month. Cloudflare Access replaced a burdensome VPN, providing secure, identity-based access integrated with Okta and automated with Terraform. This partnership ensured reliable performance for students worldwide, handled 80% of the organization's traffic, and secured all internal applications, supporting OpenClassrooms' hypergrowth securely and efficiently.
