What TheGreenBow does
TheGreenBow, operated by Sistech S.A., is a French cybersecurity software publisher founded in Paris in 1998 that develops IPsec VPN client software for endpoint secure connections across Windows, Linux, macOS, and Android. Its core offering, branded Endpoint Secure Connection, includes Windows Standard and Enterprise editions, Linux clients for Ubuntu and Red Hat/CentOS, and the Bowrealis Console for license activation and fleet management. The company differentiates through certification: it was the first European VPN provider to obtain Common Criteria EAL3+, NATO Restricted, and EU Restricted approvals, and it holds the 'Used by French Armed Forces' label from the DGA. It is also developing post-quantum cryptography through the RESQUE consortium with Thales, CryptoExperts, and ANSSI, with a quantum-resistant VPN client announced for 2026.
TheGreenBow monetizes through a hybrid model combining one-time perpetual client licenses, recurring annual maintenance and support subscriptions, professional training (BASE and ADVANCED modules at €750-€1,500), and a sub-€1/user/month public-sector offering (VPN Français) distributed via UGAP, RESAH, SIPPEREC, and HELPEVIA. It serves government ministries, defense and intelligence organizations, Operators of Vital Importance (OIV), healthcare networks, and large enterprises, with named clients including the French Ministry of the Interior, Dassault Aviation, INSEP, French Armed Forces, NATO, and the European Union. The company is privately held under the sole ownership of Athena Family as of June 2025.

- Stormshield: French cybersecurity vendor (subsidiary of Airbus) offering certified firewalls, endpoint security, and data protection. Most direct French/European cybersecurity peer, competing in ANSSI-certified segments and French government accounts.
- OpenVPN: OpenVPN provides commercial VPN client/server solutions including CloudConnexa and Access Server. Most direct software-only peer to TheGreenBow, competing on SSL/IPsec VPN client technology for enterprise and SMB customers.
