Nutanix Flow Network Security review
A focused choice for Nutanix environments needing policy simulation and a 60-day evaluation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nutanix Flow Network Security is a software-defined network security product for Nutanix environments. It is designed for enterprise teams securing hybrid and multicloud applications, databases, virtual desktops, and shared infrastructure. The product uses application-centric microsegmentation with dynamic workload categories, distributed software-defined firewalling, and workload-level policy controls. Administrators can segment east-west traffic by port and protocol, while supporting both virtualized and containerized workloads, including workloads on the Nutanix Kubernetes Platform. Deployment is agentless, with management through Prism Central.
Licensing is included with Nutanix Cloud Infrastructure Pro or Ultimate, and the product offers a 60-day evaluation. The published licensing structure makes it most relevant to organizations already operating within the Nutanix ecosystem rather than teams seeking a standalone microsegmentation product or a perpetual free plan. Its policy capabilities cover application tiers, workload categories, Active Directory group membership, ports, and protocols. Role-based access control supports separate administration of security policies, while policy simulation and preview help teams review changes before enforcement.
Flow Network Security also provides application workflow and network-flow visualization, monitoring and enforcement modes, and policy-based integration with Layer 7 security tools. Integrations include Check Point, Cisco, Fortinet, Gigamon, Juniper Networks, and Palo Alto Networks, giving security teams options for connecting existing security-network controls. It suits organizations that need distributed firewalling and identity-aware segmentation across hybrid environments, especially when a staged evaluation is useful. Teams outside Nutanix environments, or those prioritizing a broad integration ecosystem beyond security-network vendors, should consider alternatives with a different platform focus.
