**Vendor:** COSGrid Networks  
**Category:** [Firewall Software](https://www.g2.com/categories/firewall-software)
## About Nexus Shield
COSGrid NFRxG is a software-defined, AI-driven Next-Generation Firewall (NGFW) built on a Zero Trust Architecture to deliver adaptive, high-performance security across hybrid and multi-cloud environments. Unlike traditional hardware-centric firewalls, NFRxG combines deep packet inspection, intrusion prevention, SSL/TLS traffic inspection, and application-layer visibility into a single flexible platform — without the complexity. NFRxG enforces identity-aware, least-privilege access policies that continuously adapt to the evolving threat landscape. Its AI-driven threat detection engine identifies and blocks ransomware, zero-day attacks, phishing, and application-layer exploits in real time, while micro-segmentation prevents lateral movement within the network. Encrypted traffic is fully inspected for hidden threats without degrading performance. Beyond pure firewall functionality, NFRxG integrates natively with COSGrid's NetShield NDR for proactive threat hunting, SD-WAN capabilities via RuFoX for intelligent traffic routing and WAN optimization, and ZTNA 2.0 for secure remote access — all manageable from a centralized dashboard with full network visibility. Designed for enterprises, branch offices, and distributed infrastructures, NFRxG secures both managed endpoints and unmanaged IoT/OT devices through anomaly detection and dynamic segmentation policies. Key capabilities include: AI-driven intrusion detection and prevention (IDS/IPS) SSL/TLS encrypted traffic inspection Web and content filtering with role-based, real-time URL blocking Application visibility and control — detect shadow IT, block risky apps Intelligent traffic routing with QoS, load balancing, and failover IoT/OT device protection via anomaly detection and micro-segmentation Native integration with NetShield NDR, SD-WAN, and ZTNA 2.0 Centralized management dashboard for unified visibility Software-defined, Zero Trust architecture — no hardware lock-in
