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.

Solution ensures website availability and proactive threat mitigation

Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

Quotes from Members

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

Pros

"The integration of Cloudflare with Cloud Suite is its most valuable feature."

"Technical support has a very fast response time and they are helpful."

"The security features are valuable. The particular feature we use is called OWASP."

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

"Cloudflare is cheaper compared to Azure WAF, which I have considered before."

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

"There is a huge signature repository"

"The product has improved our security posture by blocking bad actors."

More Cloudflare Web Application Firewall pros

"The setup of Imperva DDoS was easy."

"The most valuable features for us are the DDoS and Bot."

"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."

"Compared to other web application firewalls in the market, Imperva does things in the most accurate way."

"Imperva DDoS is fairly stable, and its availability is quite high."

"The most valuable features of Imperva Web Application Firewall are the monitoring of databases and the dashboards are easy to understand."

"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."

"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."

More Imperva Application Security Platform pros

"I would give Radware Kubernetes WAF a rating of 10 out of 10."

Cons

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

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

"The learning curve was steep initially."

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

"Support can be challenging at times."

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

"The reporting could be more granular."

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

More Cloudflare Web Application Firewall cons

"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."

"We had an issue when securing the web applications for DDoS protection."

"It would be nice to have more security control over mobile applications so I would suggest adding more mobile security features. It would also be beneficial to see improvements in regards to interface bandwidth performance, CPU time, and RAM size. Learning capability of the device is quite weak."

"I would like to see automated reporting to improve visibility."

"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."

"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."

"The only disadvantage of Imperva is that it is a pretty costly solution."

"Imperva Web Application Firewall is very expensive."

More Imperva Application Security Platform cons

"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."

Pricing and Cost Advice

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

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

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

"The solution is expensive."

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

"The annual licensing fee is $10,000 USD."

"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."

More Cloudflare Web Application Firewall pricing and cost advice

"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."

"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."

"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."

"There are a couple of different licensing models."

"Imperva Web Application Firewall is expensive."

"There is a license or subscription renewal that our customers pay."

"The data packages are higher than our needs so we end up paying for data that we don't use."
