Is NexusShield the same product as NFRxG?

Yes. NFRxG refers to the same product now branded as COSGrid NexusShield, COSGrid's next-generation firewall.

How does NexusShield differ from traditional firewalls?

Unlike traditional firewalls that rely only on ports and protocols, NexusShield performs deep packet inspection, application-aware policy enforcement, encrypted traffic inspection, AI-driven threat detection, and Zero Trust access enforcement.

Does NexusShield support SSL/TLS inspection?

Yes. NexusShield inspects SSL/TLS encrypted traffic to detect hidden malware, phishing payloads, command-and-control traffic, and other advanced threats without compromising performance.

Can NexusShield integrate with SD-WAN and ZTNA?

Yes. COSGrid NexusShield integrates with COSGrid's SD-WAN and MicroZAccess ZTNA solutions to deliver a unified SASE and Zero Trust architecture.

Compliance-ready

Audit reporting built in, no additional tooling required

Use cases

Built for every access scenario

AI-driven detection across every traffic layer

Block ransomware, zero-day attacks and phishing with AI-driven threat detection across all traffic — before threats ever reach your network. Continuous detection runs at every layer, so known and emerging threats are stopped without manual signature updates or added latency.

Zero Trust access for remote users and devices

Enforce Zero Trust access for remote users and devices without exposing internal networks, no matter where your team works from. Every connection is verified against identity and device posture before access is granted — giving hybrid teams secure, consistent access without a traditional VPN.

Full visibility without the performance hit

DNS-layer blocking stops malicious domains at resolution — preventing access to known threats, phishing sites and unwanted categories before any connection is established.

Anomaly detection for unmanaged devices

Posture monitoring runs continuously, with automatic quarantine for non-compliant devices and complete audit logging — giving your compliance team the evidence trail auditors expect without manual tracking.
