Security management has reduced ransomware risk and now protects cloud workloads efficiently
The best features that Barracuda WAF-as-a-Service offers are an intuitive centralized dashboard, allowing us to manage policies, Internet protocol servers, antiviruses, anti-DDoS attacks, and traffic shaping across multiple sites. This feature enables seamless scaling of our environments, especially as we work within Amazon Web Services. Additionally, real-time threat intelligence helps us to detect threats in real-time. Another major feature I love is application control and VPN support, providing granular visibility and protection without needing separate appliances. The centralized dashboard is helping us streamline visibility across our admin panels and provides site-to-site visibility deployed directly to our AWS environment, securing VPC traffic and ensuring the firewall is in place. The real-time threat intelligence is an advanced feature helping us track real-time attacks, such as anti-DDoS attacks, ransomware, or viruses that can compromise system integrity. Through the intuitive centralized dashboard, we can manage policies and set rules, assisting us effectively.

Mutual TLS has secured our web services and now needs broader protocol support
The most valuable feature we have found in Microsoft Azure Application Gateway is mutual TLS. We find mutual TLS valuable because we can verify the client securely by setting up the trust certificate of the client, and also if we do it at the client side as well. This successfully develops mutual trust, ensuring that we know the client who is calling our service is a legitimate client. That is a very nice feature.Microsoft Azure Application Gateway has helped manage our traffic efficiently because we have many web services that we can put behind the same URL, and we can have different URLs with the same Application Gateway with a limited number of listeners. We can do host-based routing as well as URL-based routing or path-based routing. It supports both, so we can have even a single URL supporting many applications, or we can have different URLs for different applications respectively. We have both use cases.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."
"It provides an ease of policy management."
"The product's bot protection feature is valuable for our company."
"The solution can be used for threat prevention or as a cloud-to-cloud backup system"
"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."
"Barracuda WAF-as-a-Service has positively impacted our organization by reducing cyber threats like ransomware and phishing by ninety-five percent."
"This is a SaaS product, so it is always up to date."
"It is a scalable solution...The installation phase of Microsoft Azure Application Gateway is very easy."
"I find Application Gateway’s WAF module valuable because it helps prevent layer 7 attacks."
"The production is a valuable feature."
"We chose this solution in the first place because it has access to Layer 7. I can control the requests and the content, which I can access on my network if I want to even if it's forbidden access to other external resources. If I want to monitor, for example, traffic, and apply this rule on Layer 7, I can do so. This was our main goal when implementing this application. We wanted to take advantage of the Gateway capabilities."
"The most valuable feature is WAF."
"The best features for Microsoft Azure Application Gateway basically protect your application and provide security-related features and also divert the traffic to different instances of your application."
"The tool is easy to use and quite flexible. It has policy management features as well. The solution screens all traffic to our web applications before passing it to the application. We recently tested it on one of our poorly developed applications, and the upgrade gave us a 100% result based on our tests. It's very effective as a security measure, and people can detect threats even through the web application."
 

Cons

"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."
"The stability of the product is an area of concern where improvements are required."
"We found it a bit slow when accessing it through the web browser. The URL also exposed the user name and the hashed password. When I log into my Barracuda WAF user portal, I could see the username and the hashed password on the URL itself. So, it is not very secure, and it is important to take that off."
"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."
"The support can be improved when you are configuring the system rules. The Disaster Recovery feature can be added in the next release. The price of the solution can be reduced a bit."
"It does not have the flexibility for using public IPs in version 2."
"The pricing of the solution is a bit high. The solution should offer different pricing systems."
"The tool's pricing could be improved."
"The security of the product could be adjusted."
"Microsoft Azure Application Gateway's first deployment is complex. It needs to improve its pricing."
"Microsoft Azure Application Gateway is harder to manage than Imperva. It is not intuitive and stable compared to other products."
"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."
 

Pricing and Cost Advice

"The product is expensive but it offers flexible pricing. It could be affordable."
"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."
"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."
"I would rate the pricing a three out of ten, with ten being cheap and one being expensive."
"The solution is reasonably priced compared to other solutions."
"The solution is reasonably priced."
"There is some additional cost, such as extended support."
"Microsoft Azure Application Gateway is expensive."
"Microsoft Azure Application Gateway is a pretty affordable product. My company needs to make yearly payments towards the licensing costs of the solution. The additional costs apart from the licensing costs of the solution vary."
"There is a need to pay a fixed price per month to use the product. There are no additional payments to be made to Microsoft apart from the charges paid towards the monthly licensing costs attached to the solution."
"The solution is cheaper than Imperva. I rate it four to five out of ten."
