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.

Quotes from Members

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

Pros

"​Purge pages: It is a fast solution for updating my content from all datacenters."
"It has helped improve load speed on the site."
"The control panel is nicely laid out and I do not have to hunt for functionality."
"It is extremely easy to set up and integrate with WordPress and purge files as needed through the control panel."
"I selected CDN77 because it has servers where our different target markets are (some are in Asia)."
"It has improved our organization by providing quick access to resources."
"F5 Silverline offers load balancing, flexibility, and reliability."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"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."
"F5 technical support is really good."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"The product’s UI is easy to understand."
"The most valuable features are the configuration and configuring the process."
 

Cons

"If you are a low-use user and not used the minimum credit, it will be lost at end of year unless you upgrade, then you are left with more bandwidth than you can ever use."
"A year ago, I had to deal with SEO factors involving duplication of content."
"Automating processes could enhance F5 Silverline Managed Services."
"F5 Silverline Managed Services can improve by reducing the price."
"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."
"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."
"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."
"You need to have Linux knowledge in order to use the shell."
"I just hope the price can be cheaper."
"We'd like more AI to be used. Right now, they don't use it enough."
 

Pricing and Cost Advice

"I would suggest low usage cases that there are other options available, such as WordPress's own CDN."
"For low-use users, it can be more expensive than it seems. It would be a disadvantage for a lot of hobby users."
"Regarding the pricing, it is expensive. It may not suit others. I suggest a lower recharge level and also to remove the credit expiry time​."
"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 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 reduced."
