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.

Easy to install platform with valuable policy management features

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

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

Pros

"Centralized, full-featured DNS."
"Generally, I am satisfied with this product."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"The solution is stable, and the DNS servers are simple to use."
"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."
"The solution offers the flexibility to control configuration rules."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The solution provides good load balancing and protection against DDoS attacks."
"The product's bot protection feature is valuable for our company."
"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 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."
"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 valuable feature of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."
"The most valuable feature is flexibility."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"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 stability of the solution is very good."
"F5 Silverline offers load balancing, flexibility, and reliability."
 

Cons

"Latencies are always a problem."
"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."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The stability of the product is an area of concern where improvements are required."
"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"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."
"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."
"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."
"We'd like more AI to be used. Right now, they don't use it enough."
"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."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"Automating processes could enhance F5 Silverline Managed Services."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"F5 Silverline Managed Services can improve by reducing the price."
 

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."
"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."
"A free version of the solution is available."
"The price is reasonable."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The cost primarily depends on the size of the organization."
"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."
"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 price of F5 Silverline Managed Services could be reduced."
"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."
"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."
