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.

Application security has protected critical banking services while policy learning minimizes false blocks
F5 Advanced WAF performs well overall, but I have noticed some points that could enhance the solution. Initially, policy tuning could be simpler, as while the learning engine is powerful, initial tuning still requires experienced engineers, which can be challenging for new teams due to the complexity of options and parameters. A more guided and simple tuning workflow would help reduce the learning curve. Additionally, tighter native integration with SIEM or SOAR tools would simplify correlation and investigations for security teams, although log exports are available. Overall, these are not blockers, merely enhancement opportunities, and once tuned, F5 Advanced WAF is very stable and reliable; improving usability, reporting, and onboarding would make it even more effective for larger environments.

Quotes from Members

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

Pros

"We only need one subscription to be protected against both active DDoS and offline DDoS attacks."
"Parameter Protection is a valuable feature."
"Has a good dashboard."
"It allows us to scale out to multiple phase servers."
"It is stable and the performance is good."
"The solution has been quite stable. It's reliable."
"Since implementing Barracuda, I sleep smoothly knowing I have protection."
"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 web application firewall itself is most valuable. It provides positive security and negative security. In negative security, it blocks a task such as cross-site scripting, code injection, etc. In positive security, it lets you specify and enforce things, such as the parameters allowed in username and password fields and the number of characters allowed in a field."
"Customers find the load balancer feature as the most valuable."
"F5 Advanced WAF is a comprehensive community platform with a strong commitment, making it valuable for businesses."
"With F5 Advanced WAF, it was protection for online publications and for our customers that caused us to choose the platform."
"The most valuable feature of F5 Advanced WAF is its extensive set of capabilities for application protection, including DDoS prevention, and its ability to work with Pentesters and external scanners to observe user activity and eliminate false positives."
"This solution inspects your traffic and based on that, automatically create distinct qualities for you, so you can add this to the policy already created. That's what I like most."
"WAF functionality is valuable for protecting applications from attacks."
"F5 Advanced WAF has positively impacted my organization by stopping most web application attacks on our web servers."
 

Cons

"The documentation is lacking. It's not like what you'd get if you were using Juniper or Cisco. They need to expand on it and make it more useful."
"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."
"There are false positives that I am receiving when compared to other WAFs. The issues with false positives affect client transactions, leading to complaints about blocked transactions."
"I would suggest that someone implementing this product is knowledgeable in the IT field, and with the network needs. It is complex."
"The usability of the interface could be improved."
"It would be better if their updates would be released annually."
"I have to go to an individual obligation, make changes, and come out, and go to the next obligation and make the same changes. There is no grouping option."
"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."
"While F5 Advanced WAF does limit the number of partners in certain regions to ensure successful business transactions, they could also benefit from expanding their partnerships and making it easier for more people to learn about and become experts in F5 Advanced WAF. By doing so, they could increase the reach and exposure of their solution, similar to how Cisco has become widely recognized in the security industry."
"The administrator's user interface and some of the settings can sometimes be very complicated to understand."
"There is a learning curve that extends the time of implementation."
"It's sometimes difficult to customize APIs with F5 Advanced WAF."
"F5 Advanced WAF could improve the precision of the scanning. There are many false positives. They should improve their threat database."
"Support is a little slow."
"The product could be more user-friendly, particularly the user interface for administrators."
"The pricing could be more flexible."
 

Pricing and Cost Advice

"The price of this solution is okay."
"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."
"While I would have to check on the price of the solution, I feel it to be okay and it matches the market price."
"Our licensing fees are paid annually and the cost is between €600 and €800 (approximately $665.00 to $885.00 USD)."
"They have competitive pricing."
"The pricing is reasonable."
"The product is inexpensive."
"The product pricing was competitive for the value it offers regarding security features."
"It is expensive. Its price should be better. Its licensing is on a yearly basis. Its licensing is also based on the model. There are no additional costs."
"F5 bundles up services and the bundle is what you pay for rather than individual components."
"The pricing of F5 Advanced WAF is more expensive than other solutions like Radware and CD18, it is quite high."
"A yearly license for F5 Advanced WAF is expensive."
"Licensing fees for this solution are paid on a yearly basis."
"I don't have any issue with the pricing of this solution."
"F5 Advanced WAF is not a cost-effective solution. Although they are attempting to reduce prices with their VE and cloud options, they are more expensive than other solutions. The solution is more expensive on average."
"I am not sure about pricing but licenses are available on Google."
