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.

Centralized security has protected APIs and optimized multi‑cloud traffic management

F5 Distributed Cloud Services has been used for two years for DDoS protection, and there is a particular feature called API protection. Within API protection, there is malicious user mitigation, which is one particular technology that has been implemented. This is a kind of advanced bot attack prevention. Malicious user mitigation is an AI/ML-based technology that was introduced by the F5 team, and this particular MUG protects rate limiting. If some users are having anomaly detection or someone is trying to do a bot attack, it will create a CAPTCHA challenge for that particular user alone and not for all users. For example, if someone is trying to act as a rogue, it will create a CAPTCHA challenge in the backend system on that particular system, so they cannot try again and again at the same time. It is for a concurrent session, and it will give the CAPTCHA challenge. This MUG, malicious user mitigation, prevents bot attacks. F5 Distributed Cloud Services includes the real-time intelligence feature, which helps with threat response strategies from a threat intelligence perspective. For example, if there are geo-restrictions or geo-based restrictions, sometimes people may come in through proxy-based servers, and it will prevent that. The load balancing feature optimizes application performance. Observability is the basic piece where F5 got introduced. This observability piece provides end-to-end visibility on the application performance. It gives complete end-to-end visibility across network latency and application performance issues. Sometimes when it is getting more than 200 pages, it throws errors such as 300, 400, or whatever has been configured, including 500 errors. F5 Distributed Cloud Services has helped improve traffic management efficiency. Most applications are hosted in the Check Point and F5 firewall, F5 web application firewall, where applications and traffic management can be accessed in a single dashboard. Automated threat detection is a basic feature of F5 Distributed Cloud Services meant for that purpose. There are two scenarios with automated threat detection, which is provided by F5. It is a completely machine learning solution that came from the bot defense, and it automatically protects against sophisticated attacks.

Offers better visibility into user sessions compared to other solutions

Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.

Quotes from Members

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

Pros

"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."

"The product has a valuable security control functionality."

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

"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."

"There is a huge signature repository"

More Cloudflare Web Application Firewall pros

"Elastic environments are the most valuable features because I can pull these apps and migrate the on-premises environment to the Distributed Cloud environment, and this capability is very strong and the security regarding the apps is really very powerful."

"The main benefit is Web App Security, offering a complete security package from DDoS to web application firewall, API protection, and bot mitigation."

"In a multi-cloud or distributed cloud, there are many protection possibilities from data to web application or API protection, including bot mitigation."

"F5 Distributed Cloud Services provides a single unified console for security operations, network operations, and DevOps across all environments."

"F5 is known for being the best load balancer in the market. Customers with an existing module can easily adopt additional modules without investing in new hardware."

"I appreciate the UI of F5 Distributed Cloud Services and the backend cost, alongside the actual value proposition that they provide with the load balancer, which is excellent."

"Technical support from F5 is good compared to Cisco and HP."

"F5 Distributed Cloud Services is the market leader in load balancers and manages traffic really well."

"Very stable."

"The most valuable feature is the content switching."

"It was very easy, the NetScaler community is very big."

"I found that the GUI was very easy to to navigate. If you were looking for something, it was fairly easy to find. There's a lot of third-party documentation and information available online as well."

"My advice to anyone who is looking at implementing Citrix ADC is if they need flexibility, it's a stable product; it's one of the better appliances that I have used, even in a virtual environment, it's working great."

"The feature that I have found most valuable is its load balancing."

"We appreciate that this solution facilitates our access to Citrix internet."

"With Netscaler, we have a solution divided in two data centers, a secure and unique point of access, and balanced traffic between all the critical components in the Citrix solutions."

More NetScaler pros

Cons

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

"The ModSecurity core rules need to be updated."

"We have noticed some latency when the call goes through the firewall. That could be improved."

"The learning curve was steep initially."

"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."

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

"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."

"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."

More Cloudflare Web Application Firewall cons

"For small players, it is completely not worth it."

"The worst experience is that with so many solutions available, it is very complicated to know all of the solution modules, and the offers from F5 Distributed Cloud Services are vast."

"Last year there was a downtime of 30 minutes across the cloud distributed console, and that was the only impact observed."

"One area where F5 Distributed Cloud Services can be improved is in API security, which can be enhanced."

"The main issue is integration with other parts or products of F5, like on-premise WAF. There are some problems, mainly from the perspective of implementation and customer expectations, which sometimes differ from reality."

"The pricing could be adjusted to better meet the needs of typical customers in regions like Poland, where the product is considered too expensive."

"Currently, the support team's responsiveness is lacking, and the technical personnel on calls often seem unfamiliar with the issues or inadequately trained."

"The interface needs to be improved because the competition is coming up with ones that are more eye-catching, straightforward, and sophisticated."

"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."

"We are looking for some in-depth monitoring and analytics and more information that Citrix Director doesn't provide. ControlUp has insights that not only give you an overview but also allow you to do some drill-down troubleshooting for what's going on in your environment. We are looking for some more analytical and monitoring data to be able to monitor the environment better, not only from an application standpoint but also from the standpoint of the infrastructure to everything it sits on. They can provide more data to the administrators about what's going on within the application. They can provide data not only on the application side but also about what the application sits on. They're making strides with Citrix Analytics in regards to that."

"There are some drawbacks, such as using EUG for specific configurations. It could be improved."

"A big requirement for us is to be able to scale for multi-tenancy, and this solution doesn't really provide for that."

"The reporting is not so good. They don't have an application to connect the logs."

"The vendor provides frequent patches, however, the security of the website has room for improvement."

More NetScaler cons

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."

"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."

"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."

"It is not too pricey."

"It starts at $20 and can easily go up to $200 monthly"

"The solution is expensive."

Information not available

"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"

"For the specific use case that my customers primarily engage with, I would give the pricing a rating of seven out of ten."

"It's not for startups or SOHO."

"The licenses for this product are payable as a yearly subscription, and carry a high price-point. The subscription scheme is quite complicated, and costs will increase with each additional feature that is required, outside of the basic setup."

"The licensing costs for this solution vary depending on which model is being used."

"Its licensing cost is much higher than other products, but it is acceptable because it is a one-time investment, and we are getting our requirements fulfilled when we buy this product. So, there is no issue with the pricing."

"The price for Citrix ADC here in Mexico was good, when you compare it with F5 and Radware."

"Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for."
