Ericsson 5G Security

Ericsson 5G Security represents a comprehensive, carrier-grade telecommunications security framework and product portfolio designed to safeguard 5G mobile networks, telecommunications infrastructure, and mission-critical enterprise private cellular networks against cyber threats. As 5G technology introduces software-defined networking, network slicing, cloud-native virtualization, and massive IoT connectivity, the telecom attack surface expands exponentially. Ericsson 5G Security delivers built-in, defense-in-depth security spanning radio access networks (RAN), 5G core networks, and edge computing nodes. The architecture incorporates advanced cryptographic protections, including standardized 5G subscription permanent identifier (SUPI) encryption to prevent IMSI catching and eavesdropping across radio links. Ericsson provides automated security policy management, network slice isolation, and zero-trust identity verification, ensuring that mission-critical industrial traffic, public safety networks, and general commercial traffic remain strictly segregated and protected against lateral movement. The solution includes continuous security assurance testing compliant with 3GPP and GSMA NESAS (Network Equipment Security Assurance Scheme) standards, validating hardware and software integrity against tampering. Ericsson 5G Security enables telecom operators and enterprises to deploy trustworthy, resilient high-speed cellular networks that withstand nation-state cyber threats and safeguard vital societal communications.
