    GREYCORTEX Mendel
    Current network security tools leave networks vulnerable because of a lack of detection for advanced threats, lack of visibility, and a lack of integration. This means threats hide in the network, infected devices and misconfigurations go unnoticed, and analysts must switch between different platforms to stop attacks when they are finally detected. GREYCORTEX Mendel is an NDR (Network Detection and Response) solution for network security monitoring in IT and industrial (OT) networks. It combines advanced detection methods to analyze network traffic and alert you on any malicious activities, common and unknown advanced threats and network operational issues. It perfectly visualizes network communications at the user, device and application levels, enabling systems analysts and network administrators to quickly and efficiently resolve security and operational incidents.
