Azure NSG controls network access; Azure Firewall adds advanced, centralized, layer 7 security.
Picture this: you’re rolling out a new app in Azure. You must allow web traffic in, keep RDP locked down, and block risky outbound calls. You hear “NSGs” and “Azure Firewall,” and it sounds like two answers to one question. It’s not. NSGs act like close-range gatekeepers on subnets and NICs. Azure Firewall is your central, stateful, application-aware shield with logging, threat intel, and policy at scale. In this hands-on review, I break down azure nsg vs firewall in plain English. I also test real-world firewall gear that mirrors many of the on-prem needs you’ll pair with Azure, so you can build a consistent, end-to-end security posture.
TP-Link ER605 V2 Gigabit VPN Router
The TP-Link ER605 V2 is a compact, budget-friendly VPN router built for small offices. It supports up to 3 Ethernet WAN ports plus 1 USB WAN, so you can balance or fail over across ISPs. The built-in SPI firewall lets you set basic rules quickly. It integrates with Omada SDN, which helps you manage networks from a single dashboard.
I like it most for hybrid setups and branch offices. It can sit at the edge, handle VPN tunnels, and pass clean traffic to your cloud resources. For teams comparing azure nsg vs firewall, this router helps you mirror simple allow/deny behaviors on-prem. It is not a deep inspection NGFW, but it gets the job done for small sites.
Pros:
- Multi-WAN with load balancing and failover
- Omada SDN integration for unified control
- Easy policy setup with basic SPI firewall
- USB WAN for backup cellular modem
- Strong value for small businesses
Cons:
- Not a next-gen firewall (no advanced IPS/IDS)
- Limited application-aware features
- Throughput dips with heavy VPN load
My Recommendation
Pick the ER605 V2 if you need simple, dependable routing with multi-WAN and basic firewall rules. It is great for branch networks that use Azure for apps or backups. In azure nsg vs firewall planning, think of this as your on-prem edge that pairs with NSGs in the cloud. You can keep application enforcement in Azure Firewall and do straightforward site rules here.
| Best for | Why |
|---|---|
| Budget multi-WAN | Three WAN ports and USB give low-cost redundancy |
| Omada SDN users | Centralized, simple management |
| Azure hybrid labs | Mimics basic NSG-style rules at the edge |

FAQs Of azure nsg vs firewall
What is the main difference between an Azure NSG and Azure Firewall?
NSGs filter traffic at layers 3/4 on subnets or NICs. Azure Firewall is stateful, centralized, and adds layer 7 controls, FQDN filtering, and rich logging.
Do I need both NSGs and Azure Firewall?
Often, yes. Use NSGs for local subnet and NIC filtering. Use Azure Firewall for application rules, central policy, and analytics across VNets.
Where should I place rules when using both?
Put broad, app-aware rules in Azure Firewall. Keep targeted allow/deny rules at the subnet or NIC with NSGs for defense-in-depth.
How does logging differ between them?
Azure Firewall offers centralized, detailed logs for flows and application rules. NSGs provide flow logs at the subnet or NIC level.
Is Azure Firewall better than a hardware firewall?
Different jobs. Hardware firewalls protect on-prem edges. Azure Firewall secures cloud networks at scale. Many organizations use both.
Final Verdict: Which Should You Buy?
For azure nsg vs firewall, think “local filtering” versus “central, app-aware control.” NSGs guard subnets and NICs. Azure Firewall enforces application rules and logging at scale.
At the edge, pick a router or firewall that fits your size and skills. Then let Azure Firewall standardize cloud policies. That pairing gives you layered security with clear control.
