Nokia NetGuard

Nokia NetGuard is a comprehensive telco-grade cybersecurity and threat operations suite designed specifically to protect telecommunications infrastructure, 5G radio access networks (RAN), mobile core environments, and critical national infrastructure. As mobile networks transition to cloud-native, open, and virtualized 5G architectures, traditional enterprise IT security tools fall short in addressing telecom-specific protocols, signaling vulnerabilities, and distributed edge exposures. Nokia NetGuard delivers end-to-end security orchestration, threat detection, and automated remediation purpose-built for telecom operators. The suite encompasses NetGuard Security Management Center (SMC), which centralizes multi-vendor security policy administration and compliance across complex telco networks, and NetGuard Endpoint Security, which hardens specialized telecom equipment against firmware tampering and unauthorized access. NetGuard provides specialized protocol inspection for SS7, Diameter, and 5G HTTP/2 signaling interfaces, detecting roaming fraud, subscriber tracking attempts, location spoofing, and denial-of-service exploits launched against mobile infrastructure. Powered by machine learning threat analytics tailored to mobile network traffic patterns, NetGuard automates incident response workflows, isolates rogue base stations, and prevents lateral movement across virtual network functions (VNFs) and containerized network functions (CNFs), ensuring sovereign telecom compliance and unbroken network availability.
