NSv Series Virtual Firewall
As organizations migrate workloads to private and public clouds, the traditional network perimeter dissolves, creating new attack surfaces and security gaps. Protecting this distributed infrastructure requires a security solution that is as agile and scalable as the cloud itself. Simply extending physical firewalls to the cloud is often inefficient, costly, and complex.
The SonicWall NSv Series Virtual Firewall addresses this challenge head-on. It delivers the full suite of SonicWall's industry-leading next-generation firewall (NGFW) and threat prevention capabilities in a virtual form factor. Designed for deployment in virtualized and cloud environments, the NSv Series allows you to enforce consistent security policies, gain deep visibility into traffic, and neutralize advanced threats across your entire hybrid IT landscape.
The SonicWall NSv Series brings proven, enterprise-grade security to environments where deploying physical hardware is not an option. By operating as a virtual machine, it integrates seamlessly into your software-defined data center (SDDC) or public cloud infrastructure, protecting east-west traffic between virtual machines and securing north-south traffic at the virtual network edge.
This software-based approach provides the ultimate flexibility, allowing you to spin up, move, and scale security services on-demand, in lockstep with your dynamic application workloads. It eliminates hardware dependencies and enables you to build a consistent security posture that spans from your on-premises data center to clouds like AWS and Microsoft Azure, all managed from a single pane of glass.
Security services depend on the selected subscription, supported firmware, and configured inspection policies. Performance varies with traffic mix, encryption, and enabled services.
Actual capacity depends on host resources, traffic mix, and enabled inspection services.
Selecting the right virtual firewall model is critical for achieving optimal performance, security, and cost-efficiency in your cloud environment. Sizing a virtual appliance involves analyzing application throughput, concurrent connection needs, and the specific resource requirements of the host platform. NEXUS ITX helps organizations navigate this complexity.
We provide advisory assistance focused on aligning the SonicWall NSv Series capabilities with your unique technical and business requirements. Our goal is to help you build a clear and effective plan for integrating advanced security into your virtualized infrastructure.
Q: How does an NSv differ from a physical SonicWall firewall?
A: NSv runs as a virtual machine or cloud instance. Size it against the host resources, traffic path, and enabled security services.
Q: Which deployment platforms are supported?
A: Gen 7 and Gen 8 support VMware ESXi, Hyper-V, KVM, AWS, and Azure. Proxmox support is added with Gen 8. Confirm version compatibility before deployment.
Q: How is NSv licensed?
A: Licensing depends on the generation, model, platform, and security bundle. BYOL and selected marketplace PAYG options are available; confirm the applicable offering for the deployment.
Q: Can NSv and physical firewalls be managed together?
A: Network Security Manager supports centralized management of physical and virtual SonicWall firewalls, subject to supported firmware and management licensing.
Q: How do the model groups differ?
A: XS, S, M, and L are Gen 8. The 270, 470, and 870 models are Gen 7. Compare the required inspection performance, supported platforms, and host resource requirements.
