EMS / DejaVu is a network monitoring and threat detection platform developed by Cienaga Systems, designed to provide small and medium-sized businesses (SMBs) with proactive cybersecurity capabilities that were previously accessible only to large enterprises. The platform uses artificial intelligence to automate real-time network monitoring, aiming to detect threats such as brute force attacks, data exfiltration, and denial-of-service attacks. It is positioned as a simplified alternative to complex security monitoring solutions that typically require specialized security analysts to operate. EMS is targeted at organizations with under 200 employees, addressing the gap between basic security tools (antivirus and firewalls) and enterprise-grade network monitoring. The platform is also available to Managed Service Providers (MSPs), indicating support for multi-tenant or multi-client deployments. The product is designed to be low-overhead and straightforward to deploy, without requiring significant additional infrastructure or specialized staff. It monitors endpoints across an organization's network and provides response capabilities directly to the operator.
