It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.

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.

Quotes from Members

Pros

"Cloudflare has many features."
"The tool is user-friendly."
"The solution offers the flexibility to control configuration rules."
"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."
"The most valuable feature is its usability."
"The most valuable feature is its usability."
"The most valuable feature is the web application firewall."

"Cloudflare is simple to use."
"Cloudflare DDoS mitigates DDoS attacks."
"It is a stable solution."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"F5 technical support is really good."
"F5 Silverline offers load balancing, flexibility, and reliability."
"The most valuable features are the configuration and configuring the process."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."

"The initial setup is very straightforward."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"The most valuable feature of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."
 

Cons

"The solution could be more user-friendly."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Technical support is lacking."
"DNS Management."
"There should be a specific price list for enterprise-level customers."
"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."
"Latencies are always a problem."
"The initial onboarding was causing us some confusion."
"Our customers no longer use Cloudflare because its service is subpar."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The onboarding process can be improved a little bit."
"Operating and tuning the product is difficult."
"Our subscription plan for the solution has a limitation of bot signatures."
"Feedback could be enhanced."
"For the topic of improvement, providing some training material is one of my suggestions."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"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."
"The product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."
"F5 Silverline Managed Services can improve by reducing the price."
"The price is high in comparison to other products."
"We'd like more AI to be used. Right now, they don't use it enough."
"We need to have support for cloud protection, which is not offered by this solution."
 

Pricing and Cost Advice

"The price is reasonable."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The price of the solution is expensive."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The product's pricing is cheap."
"The prices are slightly expensive."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"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 product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
