Revenue is generated primarily through professional consulting services (digital transformation, cybersecurity advisory, cloud migration, SD-WAN studies) and recurring managed services (HDS hosting, security supervision, managed EDR, CERT support). Pricing is not publicly disclosed; engagement is consultative and sales-led via direct enterprise sales and event-driven demand generation at industry conferences (FIC, GS Days, Forum Cyber Sécurité). The company employs 101-250 staff and is currently expanding its Toulouse delivery capacity and XR business unit.
