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.

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.

It's not easy to get out once you're in

Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."

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

"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."

"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."

"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."

"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."

More Cloudflare Web Application Firewall pros

"It improves our scalability and responsiveness services to meet our demanding customer requirements."

"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."

"We use the solution for load balancing."

"Since the deployment is very easy and the open-source functionality saves a huge amount of cost in terms of project deployment."

"The support for all major Linux distros makes running and testing a breeze."

"Very good value for the money. One of the simplest licensing schemes in this category of products."

"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."

"I have deployed over 50 instances of HAProxy over the past 15 years and never encountered any stability issues."

More HAProxy pros

"It seems to provide a bit of useful information on website health."

"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."

"It seems to provide a bit of useful information on website health."

Cons

"If they add logs history within the Cloudflare offering, that would be a great benefit."

"The reporting could be more granular."

"The solution's learning curve can still be further reduced"

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."

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

"Cloudflare Web Application Firewall should include port forwarding features."

"The product can improve by having more multitenancy capability, which is currently not available."

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."

More Cloudflare Web Application Firewall cons

"I would like to see better search handling, and a user interface, with a complete functional graphical unit."

"HAProxy needs to improve its ability to handle a lot of connections, to be more like NGINX."

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

"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."

"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."

"It needs proper HTTP/2 support."

"The GUI should be more responsive and show the detailed output of logs."

"The tech support is good however, there are sometimes delays in resolving issues because when there is a shift change there doesn't seem to be any communication between the support staff and we are constantly having to repeat our issues to the next person."

More HAProxy cons

"Sitelock may perform a useful service, but be wary of giving them your credit card information."

Pricing and Cost Advice

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

"It is not too pricey."

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

"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."

"Cloudflare Web Application Firewall is more affordable than other solutions."

More Cloudflare Web Application Firewall pricing and cost advice

"The tool is open-source."

"The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy."

"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."

"We are using HAProxy as an open-source."

"When it comes to pricing HAProxy is free."

"It is free of cost."

"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."

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

More HAProxy pricing and cost advice

"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."

Reviews from Real Users

“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
