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.

Handles high traffic efficiently and simplifies complex routing with rule-based logic

I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.

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

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

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

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

"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. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

"The UI is good."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"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."

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."

More Cloudflare pros

"Scalable and inexpensive."

"The most important features would be the load-balancing of HTTP and TCP requests, according to multiple LB-algorithms (busyness, weighted-busyness, round robin, traffic, etc). Another important feature that we cannot live without is the username/passwd authentication for legacy systems that had none."

"We definitely saw fewer employees needed and money saved; we achieved 100% money savings and fewer employees with very little maintenance required."

"With centralized SSL termination and automated renewals now in place, that time requirement has dropped to nearly zero hours, translating to dozens of hours saved per year."

"We achieved 100% money savings and fewer employees with very little maintenance required."

"The technical support has been, in one word, perfect. Every time I call, I’m on the phone with a representative within five minutes who is highly skilled and willing to help, whether in the case of critical issues or simple advice."

"We use it as a load balancer for our application servers."

"It has allowed us to evenly distribute the load across a number of servers, and check their health and automatically react to errors."

More HAProxy pros

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

"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."

"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."

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

Cons

"The pricing could be improved."

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"The documentation could improve for Cloudflare DNS."

"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 product needs to improve its automation."

"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."

More Cloudflare cons

"HAProxy could do with some good combination integrations."

"I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy."

"Maybe HAProxy could be more modular."

"We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process."

"There is no standardized document available. So, any individual has to work from scratch to work it out. If some standard deployment details are available, it would be helpful for people while deploying it. There should be more documentation on the standard deployment."

"Pricing, monitoring, and reports can be improved."

"A significant area for improvement in HAProxy is its tenancy model; managing multiple environments can be challenging, especially with mergers, acquisitions, or domain changes."

"The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process."

More HAProxy 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."

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

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

Pricing and Cost Advice

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"The price of the solution is expensive."

"The price is reasonable."

"The product's pricing is minimal compared to other products."

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

"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."

"A free version of the solution is available."

"There are no additional costs beyond the standard licensing fees."

More Cloudflare pricing and cost advice

"HAProxy is a free open-source solution."

"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible."

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."

"When it comes to pricing HAProxy is free."

"HAProxy is an open-source solution."

"The licensing fee for the solution is $690 per unit annually."

"HAProxy is free software. There are optional paid products (support/appliances)."

"I use the open-source version of the product. I don't have experience with the licensed version of the solution."

More HAProxy pricing and cost advice

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

"The product has an affordable cost."

"The pricing is 50% less than Akamai."
