Enterprise Network Security for Multicloud Apps and Data

Flow Network Security (FNS) applies application‑centric microsegmentation using dynamic categories instead of static IP addresses. As workloads move or scale, security policies automatically follow them. FNS provides:

• Visualization of network flows to enable application dependency mapping
• Granular port and protocol‑based segmentation for east‑west traffic
• Identity‑aware dynamic security policy based on Active Directory  group membership
• Integration with partner Layer‑7 security engines
• Centralized policy management, compliance reporting, and continuous monitoring

This approach simplifies cloud microsegmentation, reduces operational overhead, and supports Zero Trust security models.

Traditional hardware firewalls focus on perimeter security and rely on static IP‑based rules. FNS provides software‑defined microsegmentation that:

• Applies application‑context and identity‑based policies
• Decouples security policy from network design or complex VLAN segmentation
• Simplifies ongoing operations with automation
• Scales seamlessly across virtualized and multicloud environments

This results in faster microsegmentation, reduced complexity, and fewer manual errors.

FNS stands out among microsegmentation platforms because it offers:

• Operational simplicity: Managed from familiar Prism Central interface.
• Rapid deployment: microsegmentation in minutes, not weeks
• App and identity‑aware segmentation: tied to business intent
• Multicloud and Kubernetes‑ready architecture: for hybrid workloads

This makes FNS ideal for organizations seeking Zero Trust microsegmentation without infrastructure complexity.

FNS aligns with widely adopted cybersecurity frameworks used to guide microsegmentation and Zero Trust architectures, including:

• Zero Trust Network Access (ZTNA)
• NIST SP 800‑207 Zero Trust
• CIS Benchmarks for workload isolation
• PCI‑DSS, HIPAA, and SOX segmentation controls
• MITRE ATT&CK lateral movement mitigation techniques

Yes. FNS uses microsegmentation and identity‑aware controls to reduce east‑west lateral movement. Even if ransomware compromises a workload, segmentation boundaries restrict access to other systems, significantly reducing the blast radius across the data center or cloud.

Absolutely. FNS is designed for multicloud microsegmentation with consistent security enforcement across:

• On‑prem Nutanix environments
• Public clouds (AWS, Azure, GCP) via Nutanix Cloud Clusters (NC2)
• Kubernetes environments running on Nutanix Kubernetes Platform (NKP)

Policies follow the application regardless of where it runs.

FNS is tightly integrated with Nutanix AHV for optimal automation and visibility.

Most organizations begin deploying microsegmentation policies the same day thanks to:

• Detailed visualization of network traffic
• Policy impact monitoring prior to enforcement
• No physical or network redesign
• Category‑based, intent‑driven policies
• Native integration with Prism

Traditional microsegmentation tools may require weeks or months- FNS makes it fast and accessible.

Yes. FNS supports service insertion for integrating third‑party L7 firewalls, IDS/IPS, and threat detection platforms. This allows customers to combine microsegmentation with deeper inspection from best‑of‑breed partners.

Nutanix Flow Network Security is a software-defined networking (SDN) and security solution natively integrated into the Nutanix Cloud Platform (AHV hypervisor and Prism management). It eliminates the complexity of traditional hardware-based networking by abstracting network services into software, allowing them to travel with workloads wherever they reside.
