Overview

Cedexis was a MultiCDN platform specializing in real-time traffic steering and performance monitoring, optimizing web and cloud application delivery across multiple CDNs and data centers. Founded in 2009 by Julien Coulon and Marty Kagan, it was acquired by Citrix in 2018 and integrated into its Intelligent Traffic Management (ITM) product. The platform was used by enterprises, including media outlets like L’Equipe, Le Figaro, and Le Monde, to enhance global web performance. Cedexis is now defunct, with its ITM product reaching end-of-life (EOL) in October 2025.

Migration guidance

Current Cedexis ITM customers must migrate by October 2025 to avoid service disruptions. Akamai is a strong alternative for MultiCDN traffic steering, offering robust global coverage and advanced analytics. Cloudflare provides similar real-time optimization with a broader feature set, including WAF and DDoS protection. IBM’s NS1 Connect is recommended as a direct replacement, matching ITM’s capabilities with flexible DNS-based steering and RUM data integration. Customers should consult Citrix’s official EOL documentation for transition support: https://community.ibm.com/community/user/blogs/claire-odonovan/2025/04/16/cedexis-itm-eol-ns1connect-global-traffic-steering.

History & Notes

Cedexis was known for its Radar, Fusion, Sonar, and OpenMix tools, which provided real-time visibility and programmable traffic management across CDNs and clouds. Its acquisition by Citrix aimed to bolster hybrid and multi-cloud performance but faced challenges, including a notable DDoS attack in May 2017 impacting French media clients. The decision to sunset ITM reflects Citrix’s strategic shift, with no reported plans for a direct successor. NS1 Connect has emerged as a key alternative, leveraging similar DNS-based steering technology.
