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.

Provides endless features and can be adapted to every single application that exists in the world
WAF is the most beneficial feature for security posture. Our customers are more than satisfied with the user experience provided by the product. The level of detail of the configuration is the most significant aspect. We can adapt it to every single application that exists in the world. The product helps with the compliance processes.

Long-term web protection has supported reliable traffic management but needs a simpler interface
NGINX App Protect is a good product. I have used both versions from F5 -also the free version- (I mean the NGINX/NGINX One/App Protect free trial period), and I think it is a good product. It's stable, affordable, and easy to manage. NGINX App Protect is a comprehensive security solution that combines advanced WAF, DoS protection, API security, and DevSecOps automation in a lightweight, scalable package ideal for modern cloud-native architectures. The adaptive machine learning capabilities are truly commendable, as the solution can establish traffic baselines and detect anomalies in real time. It automatically adjusts security policies, minimizing the need for manual intervention and reducing false positives. Additionally, it supports scalable deployment across diverse environments, including on-premises, cloud, Kubernetes, and containers, offering both flexibility and scalability I have experience with the web server, F5 load balancer, and similar products provided by Ergon, for eg. the web application firewall and the Microgateway for K8S. I'm also familiar with F5 BIG-IP products.

Quotes from Members

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

Pros

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

"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"Our customers are more than satisfied with the user experience provided by the product."
"I really love NGINX App Protect; I love the functionality, the ease of implementation, the very user-friendly Instance Manager, and its integration with DevOps, and as an NGINX Ingress controller using the Plus certificate it is working perfectly and making things a lot easier than the regular one while successfully stopping threats like injection, running scripts, and SQL injections."
"The solution is very good overall."
"NGINX App Protect has improved the flexibility of services in our company and distributed new escalation applications."
"NGINX App Protect's best features are auto-learning, which creates a profile of applications that are deployed, bot protection, and force protection, which lets you configure your brute force policy and alert for and prevent brute force attacks."
"We use NGINX for security headers, and as a proxy; it is also a very good tool for load balancing."
"This solution provides perfect protection for the published services against all application attacks."
"The tool's most valuable feature is the OWASP certification. Additionally, the tool's ability to enforce strong passwords and OTP within minutes is impressive. With its analytics and recommendations, it is a very good solution."
"The policies are flexible based on the technologies you use."
 

Cons

"The reporting could be more granular."
"They have some limitations with third-party integrations."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The solution's learning curve can still be further reduced"
"Support can be challenging at times."
"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."
"Their documentation could be better. They don't have documentation that explains everything well."
"The tool must be simplified."
"They have a messy license model; it's not really made for microservice architecture. It's getting expensive really, really fast."
"The price of NGINX App Protect could improve."
"The product's user interface is an area with shortcomings as it can be quite confusing for users, making it an area where improvements are required."
"The configuration needs to be more flexible because it is difficult to do things that are outside of the ordinary."
"As far as scalability, it takes a long time for deployment."
"NGINX's technical support is good, but sometimes their response time is delayed, or they don't have the technical skills to resolve issues."
"I think NGINX App Protect could be improved by having it come out of the box with NGINX."
"The contributions I think sometimes take a toll on you like you're going to spend a lot of time on the right contributions."
 

Pricing and Cost Advice

"It is not too pricey."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The solution is expensive."
"The annual licensing fee is $10,000 USD."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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."
"It starts at $20 and can easily go up to $200 monthly"
"We pay $210 per month for CloudFlare WAF."
"The tool is cheap."
"The pricing is reasonable because NGINX operates on an instance basis."
"There is a monthly or annual subscription to use NGINX App Protect. There are not any additional costs to the subscription."
"Our licensing costs are about $40,000 a year."
"The licensing fees for this solution are pretty expensive for what it does, but there is no alternative."
"The price of NGINX App Protect is approximately $3,000 annually. All of our licenses are observed by a managed service partner."
"There are no additional fees."
"There are not any additional costs we had to pay to use NGINX App Protect."
"NGINX is not expensive."
