Owner at Tech Exchange

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.

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

"The DDoS protection is the most valuable aspect of the solution."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"The most valuable feature is the web application firewall."

"Easier http to https redirect using page rules"

"Generally, I am satisfied with this product."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"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."

More Cloudflare pros

"It provides an ease of policy management."

"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 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"

"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 most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."

"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."

"The most valuable feature is flexibility."

"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 straightforward."

"F5 technical support is really good."

"The most valuable feature of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."

"The product’s UI is easy to understand."

More F5 Silverline Managed Services pros

Cons

"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."

"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."

"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"The documentation could improve for Cloudflare DNS."

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting 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."

"An integrated SSO feature would be useful for Cloudflare DNS."

More Cloudflare cons

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."

"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."

"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."

"The stability of the product is an area of concern where improvements are required."

"There is room for improvement in the stability of the solution."

"I just hope the price can be cheaper."

"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."

"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."

"The price of F5 Silverline Managed Services could be better."

"F5 Silverline Managed Services can improve by adding features that Palo Alto has."

"We'd like more AI to be used. Right now, they don't use it enough."

"F5 Silverline Managed Services can improve by reducing the price."

More F5 Silverline Managed Services cons

Pricing and Cost Advice

"We are using the free version."

"That is one of the great features. I was able to access the majority of the features and services for free."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"I give the price a five out of ten."

"We are using the free tier of the solution."

"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."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"The price is reasonable."

More Cloudflare 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 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."

The robust global connectivity cloud platform that is Cloudflare ensures users are able to connect to the Internet quickly, securely, and reliably. Cloudflare is one of the world's largest networks in the marketplace today.

millions of websites seamlessly and serves on average 45 million HTTP requests per second.

Cloudflare has safe, secure data centers in close to 300 cities worldwide to ensure every

Reviews from real users

“Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare
comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and
an SSL certificate automatically protects your website. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“The most valuable feature of Cloudflare is the GUI. You are able to control the solution very
well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company
