Experienced Full Stack French Customer Success Manager – Web & Cloud Application Development

At arenaflex, our mission is to secure the internet and protect consumer data. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. arenaflex has a kind and talented team, and while some have prior security experience, many have been successful at arenaflex without it.

About arenaflex

arenaflex started in 2018, in the wake of several high-profile data breaches. Online security was only becoming more important, but we knew firsthand how hard it could be for fast-growing companies to invest the time and manpower it takes to build a solid security foundation. arenaflex was inspired by a vision to restore trust in internet businesses by enabling companies to improve and prove their security. From our early days automating security monitoring for compliance standards like SOC 2, HIPAA, and ISO 27001 to creating the world's leading Trust Management Platform, our vision remains unchanged. Now more than ever, making security continuous—not just a point-in-time check— is essential. Thousands of companies rely on arenaflex to build, maintain, and demonstrate their trust— all in a way that's real-time and transparent.
