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

"It is stable and the performance is good."
"The product's advanced bot and threat protection capabilities are valuable."
"The installation is straightforward."
"Technical support for this solution is wonderful."
"The customer service and support from Barracuda have been excellent."
"I recommend the solution to other organizations for protecting applications specifically in Azure."
"The solution ensures layer seven is secure from attacks."
"The Barracuda Networks Web Application Firewall can protect your vital web applications from various exploits by hackers."
"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."
"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."
 

Cons

"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."
"I think the main area for improvement in this product is learning it, as can be seen when comparing it to the F5 web application firewall. F5 has a very powerful learning phase when you start using your web application firewall against your site. Barracuda has something like this, but not with the same functionality from my point of view."
"Barracuda Networks Web Application Firewall is not tightly equipped to handle application layer security threats."
"It is not stable nor mature, though it is not a problem for us."
"I wouldn't say that the solution is flexible."
"One of Barracuda's limitations is its user interface. The GUI for configuration is not intuitive and has remained largely unchanged for the past 10 to 12 years."
"We encountered a few glitches while implementing API security features into the product."
"I would like to see a native multi-cloud cover."
"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."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
 

Pricing and Cost Advice

"Cost is a bit on the higher side. Big companies can afford it."
"The price is reasonable, more so than other products."
"The price of this solution is okay."
"The pricing is reasonable."
"While I would have to check on the price of the solution, I feel it to be okay and it matches the market price."
"The Barracuda Web Application Firewall is quite expensive."
"The product is expensive."
"The solution is based on a licensing model and might be $360 for the hybrid version."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
