TheGreenBow Endpoint Secure Connection: sovereignty score and 8 European alternatives

Endpoint Secure Connection is a range of VPN client software from TheGreenBow, the trade name of Sistech S.A. in Paris, France. The clients run on Windows, Linux, macOS and Android and connect devices to VPN gateways that support IPsec or OpenVPN, depending on the edition. Features include certificate and smart-card authentication, multiple tunnels, redundant gateways and, in some editions, an always-on connection. Bowrealis Console, a separate web console installed on the customer's own network, manages licences and the distribution of VPN configurations. It serves mobile staff and teleworkers.

The vendor is a French software publisher headquartered in Paris; no parent company is stated. Because the clients are installed software and the console runs on-premises, VPN traffic and keys stay under the organisation's control instead of passing through a vendor cloud. The site does not state where the vendor hosts its own web services, but its privacy notice says personal data is hosted in the EU. No open-source licence is stated.

Why digital sovereignty matters with TheGreenBow Endpoint Secure Connection

TheGreenBow Endpoint Secure Connection is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

TheGreenBow Endpoint Secure Connection runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

TheGreenBow Endpoint Secure Connection is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs TheGreenBow Endpoint Secure Connection together with your other vendors and gives a total score, a heatmap and the main risk drivers.
