Archana Heeralal - PeerSpot reviewer
A reasonably priced product with a good UI, but the navigation is difficult, and the support team takes a long time to respond
Since we use the solution’s cloud, the product has more control over the back end. The customer will not have control. It is part of the product’s feature. When we get more complex requirements or if we want to write more complex tools, the support team will have the visibility to write them because they have control. The navigation is difficult to use. The navigation should be improved. Other products are quite straightforward. If I try to implement a new application and do an onboarding, it is not very easy. We must go to one feature, inside which there will be more features. It should be simplified, and a menu should be provided.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

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

"The most valuable feature is flexibility."
"The best advantage of F5 Silverline Managed Services is that it is easy to use."

Cons

"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"The product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."
"The navigation is difficult to use."
"F5 Silverline Managed Services can improve by reducing the price."
"The price is high in comparison to other products."
"Sometimes tech support can be slow. They take more time assigning engineers to complex issues, however, they resolve the issues by joining me to fix them."
"The price of F5 Silverline Managed Services could be better."
"Automating processes could enhance F5 Silverline Managed Services."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The product’s pricing is reasonable."
"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."

Questions from the Community

Which Web Application Firewall (WAF) would you recommend? R&S or Imperva?
Imperva is a strong choice, given their security focus and ongoing R&D into the product in areas such as bot management.
