This Python script automates the process of checking Network Security Group (NSG) details for specified subnets within the Azure environment. It eliminates the need for manual checks on the Azure portal, providing convenience and efficiency.

• Automated Subnet Verification: The script automatically verifies whether the requested subnets belong to the Azure environment.
• Efficient NSG Exploration: Eliminates manual exploration on the Azure portal by fetching NSG details programmatically.
• Comprehensive Details: Provides information on VNet, Resource Group, Subnet Range, global rules, default rules, and custom rules associated with the NSG.

• Streamlined Data Collection: Easily gather NSG data by simply entering the requested subnets.
• Automated Environment Check: No manual verification needed to determine if entered subnets are within the Azure environment.
• Quick Insights: Obtain comprehensive NSG details with just a single click.
• Reduced Manual Effort: Eliminates the need for frequent logins to the Azure portal for NSG details.

3. Enter Subnet: Input the requested subnet(s) when prompted (format: x.x.x.x/x). (*Note - there are some specific subnet range are belong to Azure Cloud so for that filteration we use python RE module)

4. Retrieve Details: Hit Enter to fetch NSG details (may take some time for searching across subscriptions).

5. Outcome: Receive details of NSG associated with the specified subnet(s).
