Manages network threats and supports application control with ease

The best advantage of F5 Silverline Managed Services is that it is easy to use. The admin guide they provide is easy to understand and allows for implementation within a few days. The traffic manager and the monitoring tool are valuable as well. The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals. It offers effective reports and monitoring capabilities.

Offers Application Protection Against Web Attacks

There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"F5 Silverline offers load balancing, flexibility, and reliability."

"The most valuable feature is flexibility."

"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."

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

"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."

"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."

"It's a good front end for public infrastructure"

"F5 technical support is really good."

More F5 Silverline Managed Services pros

"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."

Cons

"There is room for improvement in the stability of the solution."

"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."

"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."

"F5 Silverline Managed Services can improve by adding features that Palo Alto has."

"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 price is high in comparison to other products."

"The price of F5 Silverline Managed Services could be better."

"We need to have support for cloud protection, which is not offered by this solution."

More F5 Silverline Managed Services cons

"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."

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 reduced."

"The product’s pricing is reasonable."

"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."

Questions from the Community

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.
