Has helped manage client domains with streamlined access control and threat visibility
I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

Managed security rules have protected our public e‑commerce sites and simplified ongoing defense
I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF. These are managed rule sets, so you do not need to worry about continuous improvements or ensuring your application is secure; F5 Rules for AWS WAF will take care of that and is always making the necessary improvements in these rule sets to ensure security. I am very impressed with the rule sets and the continuous engineering from their security team to ensure the required rule set availability. I really appreciate the fantastic job they are doing. F5 Rules for AWS WAF can be integrated with AWS CloudFront, Application Load Balancer, Lambda, and API Gateway. I am satisfied with all these services as they are our intermediary points for services exposed to the public or globally. I gave this product a rating of ten out of ten.

Offers flexibility with a kill switch for bypassing Reblaze if needed and provides a reliable Layer 7 defense against attacks
There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town. AWS WAF, the Web Application Firewall from AWS, has a vast database of bad IP addresses due to its long-standing presence in this business. Reblaze, being a new entrant, is still building its database of bad IP addresses and malicious systems. So, Reblaze needs to work on that aspect. But other than that, I don't think scaling Reblaze has been an issue. There were some initial glitches, but they were all sorted out. So currently, I would say that the bot management and the database are areas they should focus on for further improvement.

Quotes from Members

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

Pros

"From what I've seen so far, there are no negatives to report as of yet"
"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 of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"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."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"I rate its stability a ten out of ten."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF."
"F5 Rules for AWS WAF has positively impacted our organization for security through the implementation of traffic rules in our application."
"I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF."
"The most valuable features were the real-time monitoring and the management. With this kind of product, you need a very good management system to allow you to see false positives in real-time; to see what's happening in real-time... The clarity stood out. It was very visible and very easy to navigate; very easy to find the data we were looking for."
"The best thing about Reblaze, for us, is that it has been a game changer because previously, we were using Google's Web Application Firewall, but it wasn't up to the mark."
"The main feature is using the rules and being able to see the traffic. It helps us find malicious traffic."
"We like the website protection. It's really good. The dashboard is really simple to use."
"I very much like the elastic search and reports, allowing us to have a 360-degree view of the customer's activities and enabling us to track down any suspicious bots."
"Provides mobile app security."
"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
"Reblaze knows how to manage security. For me as, someone who knows little about security, it's good that I have a firm that optimizes everything according to their standards. It's their responsibility and they are fully hands-on."
 

Cons

"The analytics, basically the dashboard, doesn't have much to it."
"An integrated SSO feature would be useful for Cloudflare DNS."
"Technical support is lacking."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"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 area for improvement I see is that while everything is in good shape, I demand continuous improvisation of these rule sets."
"An area for improvement I see is that while everything is in good shape, I demand continuous improvisation of these rule sets."
"It's too early to talk about a return on investment with F5 Rules for AWS WAF."
"The next release should have next-generation automation."
"I would like to have seen more automated reports. Maybe it has been improved in the last year and I'm just not aware of it. But from a managerial point of view, you want a summary report, a weekly report: How many attacks were blocked? How much bandwidth was saved due to the caching mechanism? What were the top-ten attacks that were tested on the network, etc? I could most likely have found all that data if I logged in to the system and ran different reports. It would be very helpful to get a management report on a weekly basis."
"There is room for improvement in helping us understanding session management... We want Reblaze to catch and identify everything. We want to see the various devices doing one activity and to see, in a timeline, what's happened. We would like to see a more human-readable display to understand what's happening in the web app."
"The WAF features are not as granular as we would expect from a WAF system. There should be more granularity and in-depth rules, out-of-the-box."
"It would be beneficial if it had a workflow or a feature that could fine-tune settings based on high-level requirements."
"Up to now the only cons I could find is sometimes getting change management back on track, because it's a company that evolves, and sometimes I don't have the same needs that they have. But besides that, up until now, I am really pleased with their service and I've also recommended them to some of my clients."
"Some of the settings on the dashboard are confusing."
"We have multiple products behind different instances of Reblaze. We have one instance for staging and then we have a production instance for multiple products. One of the things that we have requested is a unified view panel, so that we can see each of the instances in a unified view. That way, we won't have to go bouncing from instance to instance."
 

Pricing and Cost Advice

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The product's pricing is cheap."
"We don't have any issues with the price."
"We are using the free version."
"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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The price is reasonable."
Information not available
"I believe that for the six instances we have right now, it's costing us $16,000 per month."
"There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town."
"On a monthly basis we pay $750."
"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."
