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

"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"The solution provides good load balancing and protection against DDoS attacks."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The most valuable feature is flexibility."
"The best advantage of F5 Silverline Managed Services is that it is easy to use."
"The most valuable features are the configuration and configuring the process."
"The product’s UI is easy to understand."
"It's a good front end for public infrastructure"
"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."
"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."
"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 solution does not have hardware or maintenance requirements and is very easy to scale."
 

Cons

"Cloudflare's console should be made more user-friendly."
"There are some issues with the CDN services."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"DNS Management."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"The pricing could be improved."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"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."
"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."
"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."
"There is room for improvement in the stability of the solution."
"The navigation is difficult to use."
"Automating processes could enhance F5 Silverline Managed Services."
"F5 Silverline Managed Services can improve by reducing the price."
"I just hope the price can be cheaper."
"The solution needs additional product options for small and medium enterprises."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The tool is a premium product, so it is very expensive."
"The cost primarily depends on the size of the organization."
"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."
"The product’s pricing is reasonable."
"The pricing is a pay-as-you-go model that is charged by the hour."
