Genian ZTNA is a Zero Trust Network Access solution built on top of Network Access Control (NAC) infrastructure. It extends access decisions across campus, remote, and cloud environments, ensuring that identity, device posture, and context are continuously enforced throughout every session. Key capability areas include: **Network Observability:** Infrastructure-independent network sensing, device platform intelligence, IP address management, switch port management via SNMP, WLAN visibility and security, and traffic flow analysis using Netflow. **Network Access Control:** Micro-segmentation, context-based least privilege access, and multi-layered enforcement using ARP, DHCP, 802.1x (RADIUS), Cloud Gateway, Agent, and SPAN/Mirror techniques. Also includes application visibility and IP mobility via VxLAN. **Cloud Security:** Visibility into cloud infrastructure, cloud instance profiling, application-aware access control, automated cloud security group management, and Zero Trust policy enforcement for cloud workloads. **Secure Remote Access:** ZTNA agent for remote connections, biometric (FIDO/Passkey) authentication, dynamic policy enforcement via RADIUS CoA, always-on ZTNA, and IPSec/SSL-VPN gateway support. **Endpoint Security:** Endpoint visibility, device configuration, application management, compliance and risk posture measurement, and automated remediation. **5G Network Control:** Cloud gateway architecture for 5G MEC environments, mutual authentication between 5G devices and modems, and end-to-end encryption. Deployment options include self-hosted (on-premises or AWS Marketplace), cloud-managed, and MSSP models.
