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.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

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

Pros

"The volumetric DDoS defense is very good because I had a problem with a lot of volumetric DDoS attacks on my servers. After using Barracuda, those attacks have stopped and all the traffic is going smoothly to my servers and the system is working really well."
"The most valuable feature is the ease of use and the signature base."
"Some of the most valuable features are the ease of deployment, the Barracuda support, the easy-to-use console, and the granularity of the reports."
"Our customers value the solution's simplicity."
"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."
"It is stable and the performance is good."
"We use Barracuda to protect the application. That's the main feature we use it for."
"The stability of the product is good. Stability-wise, I rate the solution a ten out of ten."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"Its interface can be better. It is not very friendly."
"I would like to see a native multi-cloud cover."
"Sometimes when we put it in action, we have some blogs that appear as false positives. I think that it's improving. Barracuda should minimize false positives."
"The incident reporting needs to be improved."
"I would like to see an improved capacity to store logs so that they will be available for a longer time."
"The solution could use more reports."
"The GUI needs to be improved because it sometimes hangs and needs to be restarted."
"Barracuda Web Application Firewall lacks some of the more specified and structured features offered by solutions like Tenable."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"The UI is not very intuitive and could be better."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
 

Pricing and Cost Advice

"Cost is a bit on the higher side. Big companies can afford it."
"The product is expensive."
"For small companies, the price is very expensive because the WAF is an enterprise-level application, not intended for smaller businesses. In my opinion, the price is right for enterprise-level use."
"The pricing is less compared to other web applications."
"The price of the solution is a little expensive. There is a license for this solution and it can be purchased every one, two, or five years."
"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."
"The pricing is reasonable."
"In my opinion, the product is fairly priced."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
