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.

Has successfully filtered malicious traffic and allowed country-specific access controls
For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Quotes from Members

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

Pros

"There is a huge signature repository"
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"The setup process is very simple for me."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"AWS WAF is very easy to use and configure on AWS."
"AWS WAF has helped to strengthen the security of my environment; it has also helped to improve the posture of our application, prevent all DDoS attacks and unnecessary traffic and SQL injection that is reducing the performance of our application."
"AWS WAF is a stable solution. The performance of the solution is very good."
"The most valuable feature of the solution is the ability to integrate central sets. It protects from intrusion attacks such as scripting and SQL injections."
"This product supplies options for web security for applications accessing sensitive information."
"The most valuable feature is the ability to use the product to enhance security in deploying web applications."
"The most valuable features of AWS WAF are its cloud-native and on-demand."
"We have received good support from the customer service and support team."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product's initial setup phase is straightforward."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Its initial setup process is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The solution's learning curve can still be further reduced"
"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 should update the version of the ModSecurity core rule set that they run on."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"Its stability could be better."
"The ModSecurity core rules need to be updated."
"An improvement area would be that it's more of a manual effort when you have to enable rules. That's one of the downsides. If that can be done in an automated way, it would be great. That's a lagging feature currently."
"The price could be improved."
"The pricing should be more affordable, especially as it pertains to small clients."
"They should work to define more threats, add more security, and make it more compliant with more security companies."
"The area of reporting in the product needs to have a proper format."
"I am not satisfied with AWS technical support."
"One area that could be improved is the DDoS protection."
"The solution could improve by having better rules, they are very basic at the moment. There are more attacks coming and we have to use third-party solutions, such as FIA. The features are not sufficient to prevent all the attacks, such as DDoS. Overall the solution should be more secure."
"What I don't like about Fastly is that they charge a heavy price."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"The product should provide improved bot detection and management."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"Fastly's customer service area needs improvement."
 

Pricing and Cost Advice

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The annual licensing fee is $10,000 USD."
"The solution's pricing option needs to be more transparent for enterprise clients."
"It starts at $20 and can easily go up to $200 monthly"
"We pay $210 per month for CloudFlare WAF."
"The solution is expensive."
"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 pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"AWS WAF is pay-as-you-go, I only pay for what I'm using. There is no subscription or any payment upfront, I can terminate use at any time. Which is an advantage."
"There are no costs in addition to the standard licensing fees."
"It's cheap."
"Its price is fair. There is a very fair amount that they charge. It has a pay-as-you-go model, so it pretty much depends on how much a user uses it. As per the cloud norms, the more you use, the more you pay. I would rate it a five out of ten in terms of pricing."
"You need an additional AWS subscription for this product if you are buying a managed tool."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven or eight out of ten."
"I would rate AWS WAF's pricing a seven out of ten."
"It has a variable pricing scheme."
"You need to pay a premium price for the tool."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"In my opinion, Fastly is priced competitively."
"Fastly is less expensive than one of its competitors."
"It is an expensive solution."
"The solution is cheaper than other products in the market."
"The pricing has been very competitive."
