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

"It is a SaaS solution unlike much of the competition."

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

"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."

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

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

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

"The initial setup process is simple."

"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."

More Cloudflare Web Application Firewall pros

"Incapsula delivers a massive improvement to website performance and security in less than 20 minutes, regardless of the CMS."

"Imperva Web Application Firewall is stable."

"Provides Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner. These types of protection are valuable to the business due to the daily attacks on our portals, and that often cannot be seen without a tool like this."

"Human contact Fast SLA Trustworthy and excellent communication Highly-functional back office with user friendly reports and intelligence on bad IPS and malicious software is at very high level and very quick."

"We are using Incapsula as our web application firewall and for DDoS protection, and it performs really well at its job."

"Hands down, the WAF is the most valuable feature; being able to identify, block, whitelist or blacklist as needed, are all valuable."

"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."

"We can prevent attacks or issues even before they happen."

More Imperva Application Security Platform pros

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

Cons

"Support can be challenging at times."

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

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

"Cloudflare Web Application Firewall should improve visibility for a customer."

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."

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

"The learning curve was steep initially."

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

More Cloudflare Web Application Firewall cons

"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."

"A limited tool if you're looking to customize."

"Their portal is very limited and needs improvement."

"HTML minification could be improved. The actual HTML minification does not provide the maximum HTML minification nor provides the best result."

"Incapsula: Allow easier scripting of firewall rules."

"It should be more user-friendly. Like other web solutions, it would be helpful to be able to easily do policy configuration and identification inside the application. Understanding the in-depth configuration of a policy is somewhat difficult for an engineer, and they can improve that."

"They could improve by minimizing false positive results."

"The support for the on-premises version needs improvement."

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

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

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

"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"

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

"The solution is expensive."

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

More Cloudflare Web Application Firewall pricing and cost advice

"Everybody complains about the price of this solution."

"It is not expensive compared to the other similar solutions in this category."

"Varies depending on the needs of the customer."

"The price is high compared to other solutions like FortiWeb."

"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."

"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."

"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."

"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
