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.

Quotes from Members

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

Pros

"Does a good job preventing web application attacks."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"It protects web applications efficiently."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"Technical support has a very fast response time and they are helpful."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"The security features are valuable. The particular feature we use is called OWASP."
"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."
"The solution is effective in managing our traffic."
"Overall, it's a good solution."
"Since the deployment is very easy and the open-source functionality saves a huge amount of cost in terms of project deployment."
"I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy."
"It solves a problem for me where I can build files, not based on the health of the check, but rather the speed of the check."
"The most valuable thing for me is TCP/IP Layer 4 stuff you can do with HAProxy. You can go down to the protocol level and make decisions on something."
"HAProxy Enterprise Edition has been rock solid. We have essentially had no downtime caused by our load balancers in the last 10 months, because they’ve worked so well. Previously, our load balancers caused us multiple hours per year in downtime."
"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."
"It seems to provide a bit of useful information on website health."
 

Cons

"The solution's learning curve can still be further reduced"
"Its stability could be better."
"The ModSecurity core rules need to be updated."
"Cloudflare Web Application Firewall should include port forwarding features."
"They have some limitations with third-party integrations."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"Their documentation could be better. They don't have documentation that explains everything well. They have documentation for everything you're looking for, but they lack a single piece of documentation to tie everything together. As a new user or beginner, it took us a little bit of time to figure out how to put all these things in place."
"They have some limitations with third-party integrations."
"The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs."
"I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy."
"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."
"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading."
"The solution's dashboards and reports could be improved."
"There is room for improvement in the pricing model. It could be cheaper."
"The web stats UI, which provides the status of the health and numbers, could greatly benefit from having a RESTful interface to control the load-balanced nodes. Although there is a hack around the UI (by issuing a POST request to HAProxy with parameters), a RESTful interface would greatly improve the automation process (through Chef and Ansible)."
"In my previous job we had some stability issues related to configuration and compatibility with other products."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"It is not too pricey."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"We pay $210 per month for CloudFlare WAF."
"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 licensing fee for the solution is $690 per unit annually."
"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"HAProxy is a free open-source solution."
"HAProxy is an open-source solution."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"HAProxy is free in the initial offer. However, pricing can be improved."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
