Azure Network Security group and Azure Firewall
Azure Firewall is an OSI L4 and L7, while NSG is L3 and L4. Examine the OSI layers. While Azure Firewall is a comprehensive and robust service with several features to regulate traffic, NSGs act as more of a basic firewall that filters traffic at the network layer. Azure Firewall is adept at analyzing and filtering L3, L4 and L7 traffic.

Azure Network Security Groups (NSGs) is an OSI layer 3 & 4 network service for refining traffic to and from an Azure Virtual Network (VNet). They can be associated with subnets or network interfaces of Azure VMs. It's recommended to associate NSGs to subnets or network interfaces, but not both. The same NSG can be applied to many subnets.
Limit Network Traffic with Azure Firewall in Azure Service (AKS) Azure
Thank you for posting the question to the Q&A forum. Unlike Azure Firewall, which monitors all traffic for workloads, NSG is commonly deployed for individual vNets, subnets, and network interfaces for virtual machines to refine traffic. It does so by activating a rule (allow or deny) or Access Control List (ACL), which allows or denies traffic.
Difference between Azure Firewall & Network Security Group? The Tech Guy
As far as reporting and analytics, NS v is the clear winner. In addition of a clean and easy to operate WebUI, SonicWall NS v offers highly scalable rule management, monitoring and analytics via cloud-based SonicWall NSM, managing hundreds or thousands of instances. In short, Azure Firewall offers the sort of functionality you can find on a.
How to Set up an Azure Firewall (And Why Not NSGS)
Azure Firewall vs NSG battle continues to escalate. Both services are two primary security services from Microsoft. Each service has its perks of security on different network levels. Azure Firewall is an intelligent solution to filter network traffic. On the other hand, Azure Network Security Group provides security to inbound and outbound.
Choosing between Azure Firewall and Network Security Groups by Rolf Schutten ITNEXT
Azure Firewall offers the same capabilities as of an NSG, and many more in addition. Azure Firewall supports application FQDN tags, whereas NSG lacks this feature. Another major difference between an NSG and Azure Firewall is that Azure Firewall allows you to mask the source and destination network addresses while NSG doesn't.

3. Azure Firewall vs NSG: Application Visibility. Azure Firewall: azure firewall vs nsg vs application gateway provides detailed application-level visibility. It can identify and control traffic based on application protocols and FQDNs. This allows you to define rules that are more granular and application-specific.

Azure Firewall and Network Security Groups (NSGs) are the Microsoft solutions for Azure network security. Azure Firewall is an intelligent firewall service that provides threat protection for workloads running in Azure. In contrast, an NSG filters network traffic among Azure resources in a Virtual Network (VNet).

An Azure Firewall is a cloud-native and intelligent network firewall security service that protects cloud workloads running in Azure against threats. It provides traffic controls of both east-west traffic (between or within data centers) and north-south traffic (flowing in and out of a data center). Azure Firewall is a stateful firewall, with.

This can be achieved using NSGs and you do not necessarily need a Firewall to do the same. You can use the same NSGs if you would like, as long as the VMs are in the same region/subscription. If they are in different regions, you can still be able to use an Azure Resource Manager template to export the existing configuration and security rules.

An NSG works much like a firewall. While an Azure Firewall monitors traffic at more of a global level, an NSG is more defined and is applied to specific subnets and/or network interfaces. Both firewall and NSG allow you to apply rules based on IP addresses, port numbers, networks, and subnets.

Azure nsg (network security group) is to filter network traffic to and from Azure resources in an Azure virtual network. A network security group contains security rules that allow or deny inbound network traffic to or outbound network traffic from, several types of Azure resources whereas Azure Firewall is a managed cloud-based network.

Azure Firewall focuses on application-level inspection and centralized network security management, while Azure NSG provides granular network layer filtering within subnets or network interfaces. The choice between them depends on the specific security requirements and use cases of your Azure environment. â Previous Post.
