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

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

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."
"I just hope the price can be cheaper."
"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."
"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."
"Automating processes could enhance F5 Silverline Managed Services."
"You need to have Linux knowledge in order to use the shell."
"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."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
 

Pricing and Cost Advice

"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​."
"For low-use users, it can be more expensive than it seems. It would be a disadvantage for a lot of hobby users."
"I would suggest low usage cases that there are other options available, such as WordPress's own CDN."
"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."
"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."
