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.

Quotes from Members

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

Pros

"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."

"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."

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

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

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

"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."

"Caching is the most valuable feature of Cloudflare Web Application Firewall."

"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."

More Cloudflare Web Application Firewall pros

"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."

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

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

"It is a complete solution for those looking for an all-in-one."

"Citrix Netscaler makes it easy to provide services to end users, offering better visibility into user sessions compared to VMware. However, instability in network or machine can cause headaches as it's hard to pinpoint issues. SSL offload feature enhances security posture by providing secure connectivity between end users and backend systems. We use additional Azure remote security solutions for comprehensive protection."

"Enables a Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), and cache for CSS or JS files... You can easily use the GUI to set up all these requirements on the same network device within 20-30 minutes. (If you do the same steps on CLI, it might take less time.)"

"The web application firewall which protects our services on the internet, and then of course services like our ability to provide high availability for the services we are offering are the most valuable features."

"I like the monitoring ability as it enables me to identify when an internal (load-balanced) resource is having issues before it becomes a problem in production."

"Citrix Web App API Protection allows you to enable a blocking mode"

"Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature."

"I prefer this solution because of its user-friendly interface. I find it simple and close to what I am currently using, which is Citrix Fortiva Access for Multi-Factor Authentication. I appreciate the familiar user interface and troubleshooting tools it offers."

More NetScaler pros

Cons

"Their documentation could be better. They don't have documentation that explains everything well."

"I have experienced some difficulties with Cloudflare's support as a customer based in India."

"The reporting could be more granular."

"Support can be challenging at times."

"The reporting could be improved if it were more granular."

"There could be an option to duplicate the cluster to maintain the consistency of rules."

"They have some limitations with third-party integrations."

"The dashboard could be more user-friendly."

More Cloudflare Web Application Firewall cons

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

"The main issue is integration with other parts or products of F5, like on-premise WAF."

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

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

"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."

"I would like to see multifactor authentication added to this solution to improve the security."

"I will try to migrate all the tools to the cloud because there is more lab and more VPN scalability available in the cloud. It is not available on-premises."

"I feel that Citrix NetScaler's customer support needs to improve."

"But if they're consulting as an enterprise product and in a very large scale deployment enterprise, Citrix is not a complete solution."

"We are looking for some in-depth monitoring and analytics and more information that Citrix Director doesn't provide."

"If one device or switch fails, the failover to another device is not seamless which is painful."

"Citrix ADC can improve if it provides a more user-friendly interface and clear working protocols. Citrix is not working with classic RFC, it is working with Citrix RFC, which is not common in the world. If engineers of Citrix can provide us with more information on working with the classic IP networks it would be a benefit."

"Alert Management could be improved."

More NetScaler cons

Pricing and Cost Advice

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

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

"We pay $210 per month for CloudFlare WAF."

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

"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."

"The solution is expensive."

Information not available

"Costly product and complicated licensing."

"In Turkey, everything is good, but it seems expensive for us due to the currency exchange. I don't have a specific rating scale, but if I had to rate the price, I would say it's around a six out of ten."

"For partners, NetScaler is not as expensive price-wise versus F5."

"This product is more expensive than some of the competitors."

"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."

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

"We get value for money. Its price is fair. I don't think it is overpriced."

"The firewall license is included by default, with no additional costs."
