What is Azure Firewall?

Azure Firewall is a user-friendly, intuitive, cloud-native firewall security solution that provides top-of-the-industry threat protection for all your Azure Virtual Network resources. Azure Firewall is constantly and thoroughly analyzing all traffic and data packets, making it a very valuable and secure fully stateful firewall as a service with built-in high availability and unrestricted cloud scalability. Azure Firewall allows users to create virtual IP addresses and provides for secure DDoS protection for the virtual machines on your network. It also provides fast and efficient east-west and north-south traffic security.

Azure Firewall is a managed, cloud-based network security service built to protect your Azure Virtual Network resources. It is a fully stateful firewall as a service with built-in high availability and unrestricted cloud scalability.

Azure Firewall has two significant offerings, Standard and Premium.

Azure Firewall Standard works directly with Microsoft Cyber Security and supplies excellent L3-L7 filtering and threat awareness. The proactive real-time threat awareness will quickly alert you and immediately deny all traffic to and from any known problematic or suspicious domains or IP addresses. Microsoft Cyber Security is updated continually to protect against all new and known potential threats at all times. To learn more about Azure Firewall Standard, click here.

Azure Firewall Premium provides everything the standard version does, and additionally adds extra levels of data encryption, network intrusion detection, extended URL filtering, and Web category filters. To learn more about the added features of Azure Firewall Premium, click here.

Key Benefits and Features of Azure Firewall:

  • High availability - You do not need load balancers with Azure Firewall; it's already built in and ready to go.
  • Self-scalability - Azure Firewall is intuitive and will auto-scale as needed based on traffic flow to be ready for peak traffic times.
  • Threat awareness - Using Microsoft Cyber Security to filter traffic, Azure Firewall will deny any known problematic threats to keep your network safe.
  • Additional IP addresses - You can securely add up to 250 public IP addresses with Azure Firewall
  • Improved web category filtering - You can set up specific protocols to allow or deny categories within websites that are deemed inappropriate for use within your network. You have the ability to organize categories based on a defined set of descriptions.

What our real users have to say:

Many IT CEntral Station (soon to be Peerspot) users found Azure Firewall to be very user-friendly and easy to use. They liked that it offers seamless integration to the cloud and were especially pleased with the threat filtering options.

Regarding integration and threat intelligence, our users wrote:

“The most valuable feature is the integration into the overall cloud platform.”

The most valuable feature is threat intelligence. It is based on filtering and can identify multiple threats.”

I think that one of the best features is definitely the premium version, along with the IDPs in terms of the intrusion detection and prevention system.”

Stable and scalable with outstanding technical support
Pros and Cons
  • "The solution is very stable. When comparing it to other environments, it's actually quite impressive."
  • "We find it's different implementing it region-to-region. It might help if it was universal across all regions."

What is our primary use case?

On-premise to cloud <-> Cloud to on-premise

How has it helped my organization?

Managed service.

What is most valuable?

Scalability, multi-zone and FQDN TAgs.

What needs improvement?

In a future release, it could be empowered by combining with Azure Private DNS and Front Door.

For how long have I used the solution?

We've been using the solution for 1 year

What do I think about the stability of the solution?

The solution is very stable. When comparing it to other environments, it's actually quite impressive.

What do I think about the scalability of the solution?

The solution is scalable.

How are customer service and technical support?

We deal with technical support on a regular basis. I'd rate the service we've received ten out of most of the support tickets. 

Which solution did I use previously and why did I switch?

We use several solutions.

What's my experience with pricing, setup cost, and licensing?

Unfortunately, I don't handle the finances or payments for the solution, so I can't compare to others.

Which other solutions did I evaluate?

FortiGate - also nice solution...

What other advice do I have?

We've used both the on-premises as well as the cloud deployment models. We also occasionally use a hybrid model. During migrations, we use hybrids. Once the migration is done, we move onto the full cloud and pass if over to private cloud or have public access as necessary.

The Azure firewall is prioritized as it is managed solution and does not require any infrastructure base (backbone) hardware support.

Which deployment model are you using for this solution?

Hybrid Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Microsoft Azure

Easy to deploy and scales well, but next-generation firewall features should be added
Pros and Cons
  • "The Layer four features are okay and meet my business needs."
  • "This solution is not mature when it comes to handling perimeter traffic like internet browsing."

What is our primary use case?

We are a technical services company and we are in the data center space. We provide different solutions, including firewalls such as Azure Firewall, to our clients depending on their needs.

We have a large customer base that is global in scope and we provide hosting services as well as managed services. We have solutions deployed in both public cloud and private cloud environments. 

We typically use this solution in the perimeter layer, although we do have some use cases where we handle East-west traffic.

What is most valuable?

The Layer four features are okay and meet my business needs.

Security is playing a vital role these days, and the layer seven features such as IPS and malware protection are helpful in that regard.

The interface is fair and has not given us any challenges.

What needs improvement?

This solution is not mature when it comes to handling perimeter traffic like internet browsing. It is lacking in some of the security features. Palo Alto and Fortinet are better for this.

In the next release, I would like to see the inclusion of more next-generation firewall features.

What do I think about the stability of the solution?

So far, we have not seen any problems with stability.

What do I think about the scalability of the solution?

We are currently exploring the scalability and availability. It has a number of extensions available to increase the bandwidth, throughput, scale-up, and scale-out points.

How are customer service and technical support?

We have not been in contact with technical support.

Which solution did I use previously and why did I switch?

We have experience with Palo Alto, Check Point, FortiGate, and Cisco firewalls. Azure Firewall is more scalable than these other solutions.

How was the initial setup?

There are no big challenges when it comes to implementing this solution.

It takes approximately two hours to deploy.

What about the implementation team?

We have a lot of resources in this space, so we take care of the implementation and deployment on our own.

What other advice do I have?

This is a solution that I recommend for internet-facing network traffic.

When it comes to rating this solution, there are two components here. For layer four traffic, I would rate it an eight out of ten. For layer seven traffic, however, I would rate it less.

Overall, I would rate this solution a seven out of ten.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Microsoft Azure
