SAYSE – French SD-WAN & Cyber Software Vendor
Founded in 2014, SAYSE develops WANUP, a 100% French SD-WAN / SASE & Cybersecurity platform designed for multi-site organisations that want to unify their network and security without relying on American solutions subject to the Cloud Act.
WANUP connects, protects and supervises all your sites from a centralised management interface hosted in France: Firewall, IDS/IPS, Web Filtering, Remote VPN, ZTNA, Application QoS — all native, all included, at no extra cost.
Each site benefits from an autonomous on-premise appliance, remotely managed in just a few clicks. The result: a resilient network infrastructure, a consistent security posture across all your sites, and native compliance with European regulations — GDPR, NIS2, DORA, Cyber Resilience Act.
One vendor. One platform. Zero foreign dependency.
Sovereignty. Simplicity. Performance.
