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.

Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Quotes from Members

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

Pros

"It is configurable via API."
"In general, it's a very good product: the solution is very stable, the performance is great, the product offers very good scalability, the pricing is very reasonable, the installation is very straightforward and quite simple, and technical support has a very fast response time and is helpful."
"The product has a valuable security control functionality."
"This is a good product; it's reliable and scales well."
"It is a SaaS solution unlike much of the competition."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"The setup process is very simple for me."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The solution is scalable."
"Imperva Application Security Platform has helped reduce incidents, save time, and improve my organization's security posture with specific measurable outcomes and metrics."
"It's very pretty easy to onboard the URL."
"Imperva Application Security Platform positively impacts us because we have a critical website, so by placing a WAF of Imperva's quality, it allows us to have visibility and granular control over the various attacks that can occur on the website."
"The solution integrates seamlessly with other tools and has a good alert mechanism."
"The website itself is our first priority and we have seen improvements in that area -- it's faster."
"Hands down, the WAF is the most valuable feature; being able to identify, block, whitelist or blacklist as needed, are all valuable."
"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"Cloudflare Web Application Firewall should improve visibility for a customer."
"The product can improve by having more multitenancy capability, which is currently not available."
"Its stability could be better."
"WAF doesn't directly affect bandwidth costs. It saves costs on protection. However, with the correct setup, it's difficult to determine if it saves costs overall due to the fixed enterprise plan fee."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"Support can be challenging at times."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The interface seems a bit outdated and simplistic."
"On the negative side, API security mainly supports cloud-based solutions, while most of my customers prefer on-prem setups, so achieving high performance with on-prem solutions would be beneficial."
"The price of this solution is a little bit high compared to competitors."
"I would like the solution to improve its support response time."
"Sometimes, support tickets don't get addressed quickly."
"Its user interface could be improved, as the competition looks better, but it doesn’t really need improvements in its functionality."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"The hardware being more expensive compared to other vendors poses a challenge, along with a need for improvement in the cloud WAF offerings."
"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

"It is not too pricey."
"The solution is expensive."
"The annual licensing fee is $10,000 USD."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"It starts at $20 and can easily go up to $200 monthly"
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution's pricing option needs to be more transparent for enterprise clients."
"There are a couple of different licensing models."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"It is not expensive compared to the other similar solutions in this category."
"Pricing could be more competitive."
"The solution's pricing is an issue."
"The price is high compared to other solutions like FortiWeb."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"We are satisfied with the pricing."
