Featured Reviews

Robust protection has secured global web assets and keeps critical applications available
F5 Silverline Managed Services can be improved in areas with complex onboarding processes and slow deployment settings. Tuning of policy requires significant technical expertise, and there is a lack of knowledge in the F5 world where one needs to go through a steep learning curve in understanding what and how the policy should be configured for effectively protecting an application. These processes need to be streamlined.Knowing the limitations of F5 Silverline Managed Services, F5 has come out with a new product called F5 distributed cloud WAF platform, which has a better API integrated with security modules. It also offers advanced auto discovery, swagger, and open API validation, which is much better than Silverline.

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

"The most valuable feature is flexibility."
"It's a good front end for public infrastructure"
"I think F5 is one of the best web application firewalls in the world."
"The initial setup is straightforward."
"The initial setup is very straightforward."
"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."
"F5 Silverline Web Application Firewall works perfectly fine; it pretty much does everything that an Advanced WAF on-premises should do."
"We have a lot of businesses that we put behind this solution, and it has really helped us in terms of monitoring the logs and incidents."
"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."
"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."
"Perimeter control and active vulnerability scanner are the most valuable features."
 

Cons

"F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."
"The disadvantages of F5 Silverline Managed Services in comparison to Radware include complexities in WAF technology and iRules, which are highly useful."
"I think the management portal and the visual dashboard of F5 Silverline Managed Services could use an update."
"There is a lot of room for improvement with their tech support. I am not sure F5 Silverline Managed Services can be classified as having tech support."
"In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing."
"We need to have support for cloud protection, which is not offered by this solution."
"The price of F5 Silverline Managed Services could be better, they are not very flexible."
"One negative aspect is that the product is expensive."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"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."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"It needs more customization in PDF reports."
"There were several stability issues during the first pilot."
 

Pricing and Cost Advice

"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."
"The price of F5 Silverline Managed Services could be better, they are not very flexible. The price of the solution is based on the requirements of the enterprise."
"The price of F5 Silverline Managed Services could be reduced."
"The product’s pricing is reasonable."
"​Pricing must be cheaper than the competition and the licensing must be good.​"

Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?
For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.
