Case Study: French Presidency achieves a secure, scalable website with SensioLabs and Symfony

French Presidency scales to 150,000 concurrent visitors with SensioLabs

The French Presidency (Elysée) required a secure, scalable, and easily manageable website to modernize its digital communications with citizens. Facing challenges including high vulnerability to cyber attacks, the need to handle major traffic events, and a requirement for non-technical staff to publish content, they partnered with SensioLabs. The project involved migrating to a new platform built using the Symfony framework.

SensioLabs implemented an agile migration to Symfony, which included a one-shot data migration, rigorous security audits, automated testing, and continuous deployment. The results were a robust website that withstands DDoS attacks and scales effortlessly from 10,000 to 150,000 concurrent visitors. The French Presidency now benefits from a durable, user-friendly back-office and streamlined, semi-automated update processes.
