Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.

Mitigates more bot activity when defending web applications than any other vendor but comes at a price
F5 Silverline Managed Services is expensive. You do get world-class quality of mitigation, but I think it is still pricey. You can find similar services, potentially of slightly lower quality, from other vendors like Cloudflare or Akamai for about half the price. When you compare what you get for the money you spend at Cloudflare or Akamai, you do get less protection but you are not dishing out too much for it. On the other hand, at F5 Silverline Managed Services, you do get better protection but, but you are paying double for it. We have had mixed feedback from our clients about this. Most of them would rather pay less for a bit of a lower-quality defense than overshoot their budget. The most common piece of feedback we receive is that the difference in protection levels is not reflected in the price.

Scaling is very easy but more options are needed for enterprise environments
Our company uses the solution to provide customized infrastructure and cloud services to our customers. We currently have five to ten customers using the solution.  Our model is to continue to move toward software as a service. We already offer infrastructure and platforms as a service.  The…

Quotes from Members

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

Pros

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The solution is stable, and the DNS servers are simple to use."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The most valuable feature is flexibility."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"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."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"It's a good front end for public infrastructure"
"The most valuable features are the configuration and configuring the process."
"The stability of the solution is very good."
"The product’s UI is easy to understand."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
 

Cons

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The pricing could be improved."
"Cloudflare should add more documentation and pricing to the cloud version."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"The documentation could improve for Cloudflare DNS."
"There are some issues with the CDN services."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"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."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"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."
"You need to have Linux knowledge in order to use the shell."
"We'd like more AI to be used. Right now, they don't use it enough."
"There is room for improvement in the stability of the solution."
"The solution needs additional product options for small and medium enterprises."
 

Pricing and Cost Advice

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The cost primarily depends on the size of the organization."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"I give the price a five out of ten."
"We are using the free version."
"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."
"The pricing is a pay-as-you-go model that is charged by the hour."
