How to Go God Mode in Nutanix Flow: Unlocking Advanced Security and Automation

Paul Bryant

Nutanix Flow has rapidly evolved from simple microsegmentation to a robust enterprise security, automation, and network visibility suite. If you want to “go god mode” in Nutanix Flow—meaning complete, surgical control and insight over your application networks—this guide is your step-by-step blueprint.

I’ll cover:

1. Introduction: What Does “God Mode” Mean in Nutanix Flow?

Going “god mode” means:

With the latest Nutanix Flow, these are not just marketing claims—they’re practical and achievable for every Nutanix shop.

2. Flow Architecture: Latest Stack and Production Prereqs

Nutanix Flow is natively integrated with Prism Central (2025.x+) and AOS 6.x+. It requires:

3. Enabling Flow: Step-by-Step in Prism Central 2023.3 or later

Step 1: Check Prereqs

Step 2: Enable Flow

UI Steps

  1. Log in to Prism Central.
  2. Go to Security > Flow Network Security.
  3. Click Enable Flow for the desired cluster.

API Example (Python)

import requests

# Replace with your Prism Central details
PRISM_CENTRAL = "https://your-pc-ip:9440"
USERNAME = "admin"
PASSWORD = "your-password"

def enable_flow(cluster_uuid):
    url = f"{PRISM_CENTRAL}/api/nutanix/v3/flow/security_policies"
    headers = {"Content-Type": "application/json"}
    data = {
        "spec": {
            "resources": {
                "cluster_reference": {"uuid": cluster_uuid},
                "enabled": True
            }
        }
    }
    r = requests.post(url, auth=(USERNAME, PASSWORD), headers=headers, json=data, verify=False)
    return r.status_code, r.json()

# Usage
status, response = enable_flow("CLUSTER-UUID-HERE")
print(status, response)

4. Microsegmentation: Zero-Trust at Scale

Key Concepts:

Microsegmentation Policy Model

PowerShell: Policy Creation

# Requires Nutanix Cmdlets (Prism Central REST support)
$pc = "your-pc-ip"
$auth = @{
    Username = "admin"
    Password = "your-password"
}
$body = @{
    spec = @{
        resources = @{
            categories = @("App")
            action = "ALLOW"
            protocol = "TCP"
            ports = @(3306)
            direction = "INBOUND"
        }
    }
}
# Python: Policy Creation (Recommended)
import requests

PRISM_CENTRAL = "https://<your-pc-ip>:9440"
USERNAME = "admin"
PASSWORD = "your-password"

headers = {"Content-Type": "application/json"}
policy_data = {
    "spec": {
        "resources": {
            "categories": ["App"],
            "action": "ALLOW",
            "protocol": "TCP",
            "ports": [3306],
            "direction": "INBOUND"
        }
    }
}

response = requests.post(
    f"{PRISM_CENTRAL}/api/nutanix/v3/flow/security_policies",
    auth=(USERNAME, PASSWORD),
    headers=headers,
    json=policy_data,
    verify=False
)
print(response.status_code, response.json())

5. Advanced Policy Automation: Python, REST API, Terraform, Calm

a) Python: Bulk Policy Management

import requests

def create_policy(policy_data):
    # ...similar auth/setup as before
    url = f"{PRISM_CENTRAL}/api/nutanix/v3/flow/security_policies"
    return requests.post(url, auth=(USERNAME, PASSWORD), headers=headers, json=policy_data, verify=False)

b) Terraform: Infrastructure-as-Code

provider "nutanix" {
  username = "admin"
  password = "your-password"
  endpoint = "https://your-pc-ip:9440"
}

# Note: This is a hypothetical example. Refer to the official Nutanix Terraform provider for supported resources.
resource "nutanix_network_security_policy" "app_policy" {
  name     = "app-policy"
  category = "App"
  rule {
    action    = "ALLOW"
    protocol  = "TCP"
    port      = 3306
    direction = "INBOUND"
  }
}

c) Nutanix Calm: Automated Security Blueprints

Blueprints in Calm can include Flow policy application as part of app deployment, ensuring “secure-by-default” apps.

6. Monitoring, Troubleshooting, and Full-Stack Visibility

Flow Visualizer in Prism Central shows real-time traffic, policy hits, and violations.

Troubleshooting Commands:

7. Integrations: SIEM, SOAR, and Next-Gen Firewalls

Flow + SIEM Integration

8. Real-World “God Mode” Workflows

1. Policy Drift Remediation:
Detect and auto-repair policy deviations using Calm or Terraform.

2. Dynamic Onboarding:
Auto-apply security policies to VMs based on tags and categories (no manual steps).

3. Incident Response:
Monitor for abnormal traffic, trigger SOAR automation, and quarantine VMs programmatically.

9. Security Gotchas and Pro Tips

10. Conclusion and Resources

With Nutanix Flow’s latest releases, going “god mode” is no longer just a vision—it’s a production reality. By harnessing native automation, dynamic microsegmentation, deep integrations, and strong operational discipline, you can enforce zero-trust, streamline compliance, and gain full control of your app networks.
