The company's technology stack is built on a curated ecosystem of subcontractors and partners: Equinix France provides HDS-certified physical infrastructure; HarfangLab provides ANSSI-certified EDR technology packaged as Managed EDR; Wallix provides privileged access management; TrustBuilder provides DDoS protection; Passbolt provides secrets management; and Veeam and Nakivo provide encrypted backup.

It is a member of Hexatrust and co-founder of the Collectif Mieux RSE association.

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.
