Advanced security reporting has protected high-traffic betting platforms from constant attacks

I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Advanced protection has secured critical web workloads and provides clear traffic visibility

From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Room for improvement with user interface while competitive pricing impresses

It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

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

Pros

"This is a good product; it's reliable and scales well."

"The product has a valuable security control functionality."

"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."

"Caching is the most valuable feature of Cloudflare Web Application Firewall."

"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."

"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."

"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."

More Cloudflare Web Application Firewall pros

"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."

"The overall performance of this solution is what makes it one of the best solutions on the market."

"Easier http to https redirect using page rules"

"We're partners with Cloudflare; this solution is the best product and it does not charge you for any kind of attack on your traffic, only for good traffic, and it can mitigate up to 30 TBPS of DDoS attacks."

"The solution provides good load balancing and protection against DDoS attacks."

"This solution has improved the security of our organization."

"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."

"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."

More Cloudflare pros

"The product's most valuable feature is its ability to set up the rules easily."

"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."

"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."

"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."

Cons

"Support can be challenging at times."

"They have some limitations with third-party integrations."

"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."

"Cloudflare Web Application Firewall should improve visibility for a customer."

"It would be ideal if the solution offered better log integration and more integration with different platforms."

"The dashboard could be more user-friendly."

"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."

"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."

More Cloudflare Web Application Firewall cons

"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."

"There should at least be a read-only view of the data so that resellers can properly support the clients."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"Support response time could be improved."

"In the last two years, there has been a certain amount of downtime when using the VDM."

More Cloudflare cons

"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."

"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."

"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."

"The UI is not very intuitive and could be better."

Pricing and Cost Advice

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."

"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."

"The annual licensing fee is $10,000 USD."

"The solution's pricing option needs to be more transparent for enterprise clients."

"The solution is expensive."

"It starts at $20 and can easily go up to $200 monthly"

"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."

"It is not too pricey."

More Cloudflare Web Application Firewall pricing and cost advice

"We are using the free version."

"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."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

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

"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."

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

"The product's pricing is cheap."

"The tool is a premium product, so it is very expensive."

More Cloudflare pricing and cost advice

"The pricing is 50% less than Akamai."

"The product has an affordable cost."

"Signal Sciences is pretty cheap compared to other solutions."
