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

"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."

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

"Does a good job preventing web application attacks."

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

"It protects web applications efficiently."

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

"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."

More Cloudflare Web Application Firewall pros

"Our customers are more than satisfied with the user experience provided by the product."

"It is easy to use and has good security."

"The solution has been quite stable. I have not seen any bugs at all."

"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."

"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."

"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."

"The solution integrates seamlessly with other tools and has a good alert mechanism."

"Imperva Web Application Firewall is stable."

"The most important feature I have found to be the ease in how to do the backup and restores."

More Imperva Application Security Platform pros

Cons

"Its stability could be better."

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

"The solution's learning curve can still be further reduced"

"If they add logs history within the Cloudflare offering, that would be a great benefit."

"They have some limitations with third-party integrations."

"The dashboard could be more user-friendly."

"The learning curve was steep initially."

"The platform's control features related to real-time authentication and response time need improvement."

More Cloudflare Web Application Firewall cons

"The tool must be simplified."

"I see some areas for improvement in Imperva Application Security Platform, especially regarding price."

"I don't really use it and therefore can't speak to areas of improvement."

"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."

"Imperva DDoS does not provide version control."

"Imperva should have more points of presence in Africa."

"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'd like the option to pick your bot protection."

"It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."

More Imperva Application Security Platform cons

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."

"The solution is expensive."

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

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

"The solution's pricing option needs to be more transparent for enterprise clients."

"It is not too pricey."

"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."

More Cloudflare Web Application Firewall pricing and cost advice

"The tool is cheap."

"The tool's pricing is good."

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

"Varies depending on the needs of the customer."

"It is a very affordable solution."

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

"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."

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