Case Study: Euronext achieves continuous, rapid cyber-attack testing to safeguard Pan‑European trading with Cymulate

Euronext Safeguards Pan-European Trading with Cymulat Breach & Attack Simulation

Euronext, the leading Pan‑European marketplace with 1,300 listed companies and a €3.5 trillion market capitalization, needed a more efficient, cost‑effective way to continuously test its security posture. While its SOC and Assessment & Exploitation teams ran homegrown simulations, creating manual tests for new malware strains or zero‑day campaigns was resource‑intensive and slow, so Euronext turned to Cymulate’s cyberattack simulation platform for faster, repeatable assessments.

Cymulate was quick to deploy and let Euronext run frequent, up‑to‑date simulated attacks using modules such as Immediate Threat Assessment, Web Gateway, Email and Endpoint, and later adding the Hopper module. By rapidly incorporating IoCs, validating controls after configuration changes, complementing manual red‑team work, and providing automated executive and technical reports, Cymulate enabled Euronext to immediately see exposure to emerging threats, reduce the overhead of building manual simulations, and justify security decisions — demonstrated by renewing and expanding their Cymulate subscription.
