Senior Security Systems Engineer at a tech services company with 11-50 employees
Granular security policies have protected critical applications and ensure safe user and admin access
Improvements could be made regarding the log information from the backend CLI. There are enhancements needed; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation. These data are missing from F5 Advanced WAF. Besides that, another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients. Overall, I find everything else good. A wish list feature I have is for the Technical Assistance Center (TAC) to respond more promptly. Their response time needs improvement; while they do not take excessive time, it can be enhanced, especially given it is a security product.

Information Security Engineer at a tech vendor with 51-200 employees
Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"In terms of F5 Advanced WAF's most valuable features, I would definitely say its stability, as F5 is one of the most stable products and either as the load balancer or the web application firewall, it is very stable."
"I would recommend this solution to others who are interested in using it."
"F5 technical support is excellent. They are experts who always provide the right solution, and they understand the problem. Their response and resolution times are good."
"When you choose to go with F5, be sure to size your box properly so that the capacity is taken care of."
"The most valuable features of this solution are the WAF protection, Data Safe, and the seven-layer DDoS."
"The whole mechanism of F5 Advanced WAF is effective."
"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."
"The ROI is very impressive as it is crucial for financial applications to be protected efficiently."
"They are the only solution that fits our success criteria and business objectives: WAF must have a low (<5%) false negative rate and be ready to protect from all well-known web attacks."
"Vulnerability scanner and WAF are valuable features."
"Perimeter control and active vulnerability scanner are the most valuable features."
"The most powerful feature is the ability to first learn what type of query to make to your web application when it is attacked and what type of query creates a false positive to your app."
"With active threat detection, we are no longer over-swamped with tons of useless events."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
 

Cons

"The product could be more user-friendly, particularly the user interface for administrators."
"There is a gap in report management."
"We usually use a third-party tool for logging and reporting. It would be nice if we could do that right on this solution. They have one, but it's not very stable. Logging and reporting effectively would be a big enhancement."
"F5 Advanced WAF is not a cost-effective solution."
"Although we're getting some reports, we're not getting all the reports we need. There seems to be a gap in report management."
"I would like to see improved features in the F5 Advanced WAF solution, especially with a focus on enabling Kubernetes fully."
"I would say their graphical interface, the GUI. I don't like the GUI as much as before."
"The reporting portion of F5 Advance WAF is not great. They need to work out something better, as it is very basic. You only see the top IPs, I think there is more they can offer."
"Wallarm uses a learning mechanism to detect attacks and to avoid false positives. If Wallarm blocks some illegitimate request, then you can go to the management console and mark this request as false positive, but sometimes this does not work properly."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"There were several stability issues during the first pilot."
"It needs more customization in PDF reports."
 

Pricing and Cost Advice

"The pricing is too high."
"As far as the pricing of F5 Advanced WAF I would rate it a four out of five depending on what features I am looking for. Imperva is more expensive."
"The price of the solution is reasonable when compared with other products, such as FortiWeb. I am very satisfied with the price."
"There are different licenses available to use F5 Advanced WAF, such as BT, ASM, and LPM."
"The cost is slightly above average."
"After buying the program, you just pay for the support every year."
"I am not sure about pricing but licenses are available on Google."
"Licensing fees for this solution are paid on a yearly basis."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
