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

"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"There is a huge signature repository"
"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The product has improved our security posture by blocking bad actors."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"Imperva solutions are the best in terms of stability."
"The most valuable features for us are the DDoS and Bot."
"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
"There is no need to have an appliance in house for the services because it is on the cloud."
"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."
"Scalability has been pretty good, our European traffic has doubled and our sales have gone up along with our stability."
"The solution is really stable; it's a product that I can stand by and recommend because I know it's going to work for the customer."
"I am impressed with the product's automatic bot mechanism. It also gives us the control to create our own custom bot rules."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"The platform's control features related to real-time authentication and response time need improvement."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The solution's learning curve can still be further reduced"
"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."
"Its stability could be better."
"The ModSecurity core rules need to be updated."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"The solution works for particular zones but isn't always the best solution for all zones."
"The technical support team would be rated 5 out of 10, where 10 represents the best support and 1 represents very poor support."
"Everybody complains about the price of this solution."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"The solution should integrate with something that looks at continuous security management."
"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."
"Pricing is a challenge for most of our customers."
"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

"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."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It is not too pricey."
"It starts at $20 and can easily go up to $200 monthly"
"The annual licensing fee is $10,000 USD."
"The solution is expensive."
"The solution's pricing option needs to be more transparent for enterprise clients."
"There is a license or subscription renewal that our customers pay."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"The solution's pricing is an issue."
"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."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"Everybody complains about the price of this solution."
