Secure your business with a Zero Trust architecture
A unified cybersecurity architecture for European SMBs, built on the native Microsoft 365 (XDR) ecosystem. Protect your identities, endpoints, and corporate data against modern threats.

Global cyberattacks are directly targeting small and medium-sized businesses.
Of SMBs permanently close within 6 months of a major cyberattack.
Of security breaches are caused by human error or misconfiguration.
Why choose a Zero Trust approach?
We shift your security from a network-based model to an identity and data-centric approach. With native Microsoft XDR (Extended Detection & Response) integration, we unify detection across all layers of your infrastructure.
errorTraditional Approach
Implicit trust once the password is entered. No validation of the connection context.
Reactive protection based on known blacklists. Blind to "Zero-Day" and fileless attacks.
Users are local administrators on their machines for "ease" of use. Maximum attack surface.
Security is tied to the storage folder (File server). If the file leaves, it's no longer protected.
The internal network is assumed to be safe. Detecting an intrusion takes months (Average: 280 days).
check_circleZero Trust Approach
Continuous validation based on risk signals (Location, Device health, Application) for every access request.
Real-time analysis of processes (XDR). Data access is blocked if the device is not healthy.
Standard users by default. Temporary, justified, and audited privilege elevation only when necessary.
Security is encrypted within the file (Labels). Data remains protected anywhere, even on a USB drive.
The network is considered compromised by default. Micro-segmentation and automatic isolation of infected PCs in seconds.
