Easy to install platform with valuable policy management features

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.

Quotes from Members

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

Pros

"The solution can be used for threat prevention or as a cloud-to-cloud backup system"
"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."
"It provides an ease of policy management."
"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."
"The product's bot protection feature is valuable for our company."
"The best advantage of F5 Silverline Managed Services is that it is easy to use."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"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 is flexibility."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"The initial setup is straightforward."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
 

Cons

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."
"The stability of the product is an area of concern where improvements are required."
"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."
"We found it a bit slow when accessing it through the web browser. The URL also exposed the user name and the hashed password. When I log into my Barracuda WAF user portal, I could see the username and the hashed password on the URL itself. So, it is not very secure, and it is important to take that off."
"I just hope the price can be cheaper."
"The price of F5 Silverline Managed Services could be better."
"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."
"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."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
 

Pricing and Cost Advice

"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."
"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."
"The product is expensive but it offers flexible pricing. It could be affordable."
"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."
