Security management has reduced ransomware risk and now protects cloud workloads efficiently
The best features that Barracuda WAF-as-a-Service offers are an intuitive centralized dashboard, allowing us to manage policies, Internet protocol servers, antiviruses, anti-DDoS attacks, and traffic shaping across multiple sites. This feature enables seamless scaling of our environments, especially as we work within Amazon Web Services. Additionally, real-time threat intelligence helps us to detect threats in real-time. Another major feature I love is application control and VPN support, providing granular visibility and protection without needing separate appliances. The centralized dashboard is helping us streamline visibility across our admin panels and provides site-to-site visibility deployed directly to our AWS environment, securing VPC traffic and ensuring the firewall is in place. The real-time threat intelligence is an advanced feature helping us track real-time attacks, such as anti-DDoS attacks, ransomware, or viruses that can compromise system integrity. Through the intuitive centralized dashboard, we can manage policies and set rules, assisting us effectively.

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

"The product's bot protection feature is valuable for our company."
"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."
"Barracuda WAF-as-a-Service has positively impacted our organization by reducing cyber threats like ransomware and phishing by ninety-five percent."
"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."
"Its flexibility is the most valuable because it is a managed service. The good part is that you don't need to set it up. It just needs DNS routing, which is the easiest thing. Our client had Akamai for certain websites because they were using CDN features. They had NetScaler on the internal zone, F5 AWAFs on the data centers, and no WAF at all in the cloud. One of the main activities of the project was to move all these policies into a single WAF so that we could control and use that as a choke point. That exercise itself was very easy because it was a managed service and F5 Silverline Web Application Firewall does that for you. That's the best thing about F5 Silverline Web Application Firewall. It is easy to apply policies on-premises. If you have AWAF on-premises and you want to replicate some policies on F5 Silverline Web Application Firewall, other than the policies that it applies by itself, it is easy because you have a team that supports it. F5 Silverline Web Application Firewall works perfectly fine. It pretty much does everything that an Advanced WAF on-premises should do."
"F5 Silverline offers load balancing, flexibility, and reliability."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"The most valuable features are the configuration and configuring the process."
"F5 technical support is really good."
"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 initial setup is very straightforward."
"The stability of the solution is very good."
 

Cons

"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."
"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."
"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."
"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"There is room for improvement in the stability of the solution."
"F5 Silverline Managed Services can improve by reducing the price."
"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 of F5 Silverline Managed Services could be better."
"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."
"We need to have support for cloud protection, which is not offered by this solution."
"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."
 

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."
"The product is expensive but it offers flexible pricing. It could be affordable."
"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’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."
"The price of F5 Silverline Managed Services could be reduced."
"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."
