Has protected our legacy applications effectively but has required constant manual filtering due to false positives
I assess the effectiveness of the machine learning-driven threat detection in Barracuda Web Application Firewall as sometimes behaving abnormally, often showing me false positive attacks, so I have to fix these attacks from time to time. From a stability point of view, I would definitely rate Barracuda Web Application Firewall a seven out of ten. There is definitely some room for improvement; nothing is perfect in the world. I am not satisfied with the technical support from Barracuda. I am somewhat disappointed with the technical support that I have received so far. Whenever I generate a ticket for my problem, it goes to the Indian support team, and they all the time start with the most junior team member, consuming all my precious time. At the end, I have to close that ticket without any satisfactory solution. I have complained that they should shift my support to any other region because I don't need Indian support; they are simply pathetic and not up to mark. To improve Barracuda Web Application Firewall, customers should be given ongoing training opportunities regarding the product and its features. I am not familiar with many features that are available, only using those which are necessary for my applications. I believe Barracuda must provide clearer product information or training sessions to make it more user-friendly, as sometimes its interface can be rigid and lacking in helpful resources or user tutorials about its features. For it to get closer to a ten, I think advanced reporting is missing because, as I mentioned earlier, there are many false positive events being recorded. Often, when I analyze these attacks, they turn out to be genuine customers or users interacting with my product, but Barracuda tags them as attackers. Reducing false positives must be a priority.

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

"The most valuable feature is the rule set."
"You don't need help from Barracuda to help with the deployment. The deployment is easy."
"This product gives us visibility into what is going on in two servers, including connections and sessions, real-time alerts, very good reporting, and KPIs. It makes managing security of a critical server very easy, with a friendly GUI."
"Its recommendation about the probabilities on the website is great. It also has free probability managers for the website, which is really helpful. The protection engine, signature-based protection behavior, and analysis features are also great. It also has an ATP module for sandbox scanning and behavior analysis for file uploads."
"Even when we were upgrading to a new OS, we didn't have any difficulties with the product. The stability is good."
"It allows us to scale out to multiple phase servers."
"The product has fantastic support services."
"The initial setup is pretty straightforward, especially if you enlist assistance."
"The most valuable feature of Microsoft Azure Application Gateway is its ease of use."
"The most valuable feature of the solution is the web application firewall (WAF)."
"WAF feature replicates the firewall."
"The load balancing features are valuable."
"Using policies to link and manage these URL-based routing configurations is also valuable."
"I rate Microsoft Azure Application Gateway's scalability a ten out of ten. My company has more than 1000 users who use it daily."
"The simplicity of the solution and its ability to integrate easily with others are its most valuable aspects."
"Application Gateway automatically redirects unwanted users and takes care of the security aspect. It also handles the performance side of things, which is why we use it."
 

Cons

"We've had some blocks of the application and some false positives."
"If you know nothing about networks, then you can't set it up."
"As most people are aware, the implementation is not easy."
"I would like to see better controlling of the traffic."
"They could improve their performance, support, and their upgrades. Their updates used to be good. Their improvements were right on the money but nowadays, the updates are minor."
"The GUI needs to be improved because it sometimes hangs and needs to be restarted."
"There's potential for improvement in the platform's CMS integration."
"The solution needs to leverage some additional features to a broader scale of software-defined networks."
"In the next release, the solution could improve the integration with Service Mesh and other Azure Security Services."
"The solution has many limitations. You cannot upgrade the VPN to the application gateway. So I started with version one, which has limited capabilities, and they provided version two. And unfortunately, I cannot upgrade from v one to v two like other services. So I have to decommission the version one and create a new one with version two. Also the version one was complex with the certificates uploading the SQL certificates."
"It is a bit tricky to configure. You've got to have a very specific format to configure it. They should make it a little bit easier to configure. Mapping the certificates into it isn't easy, and it could be better. Currently, you've to write a bit of automation to pull certificates directly to HTTPS."
"We have encountered some issues with automatic redirection and cancellation, leading to 502 and 504 gateway errors. So, I experienced some trouble with containers."
"It could be more stable, and support could be better. It would also be better if they offered more features. For example, it lacks security features. Before we used another English solution, and we realized that some of the rules were not set up correctly and passed through the Application Gateway's English controllers. But the problem, in this case, is if you send ten rules, for example, six rules hit some issues. IP address blocking could be better. The rules, for example, don't work properly. If you have one issue, one rule or another rule will not work. This sounds like total madness to me."
"Microsoft Azure Application Gateway is harder to manage than Imperva. It is not intuitive and stable compared to other products."
"The tool is a pain to deal with when it comes to the area of configuration."
"Customer service can be improved. There is room for improvement, specifically in paid support, by providing more direct contact."
 

Pricing and Cost Advice

"The product is expensive."
"In my opinion, the product is fairly priced."
"The Barracuda Web Application Firewall is quite expensive."
"Cost is a bit on the higher side. Big companies can afford it."
"They have competitive pricing."
"Barracuda costs us $8,000 per year. Barracuda costs $20,000 for a full subscription, when you try to protect multi-site infrastructure, in different geographical zones and for different data centers. If you have only one site, Barracuda will be cheaper."
"Our licensing fees are paid annually and the cost is between €600 and €800 (approximately $665.00 to $885.00 USD)."
"They only offer a yearly licensing plan."
"The solution is reasonably priced compared to other solutions."
"The solution is reasonably priced."
"The cost is not an issue."
"The pricing is based on how much you use the solution."
"I rate the price of Microsoft Azure Application Gateway an eight out of ten."
"There is some additional cost, such as extended support."
"The product is not expensive."
"It is an expensive solution. We have an enterprise agreement, it is monthly."
