Herb Angle

Owner at Hga consulting

Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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 fast and secure DNS."

"The solution provides good load balancing and protection against DDoS attacks."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"It is easier to configure and develop documentation to see how we have configured firewalls."

"The solution is very good at mitigating threats."

"I like Cloudflare's application gateway and DDoS protection."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."

More Cloudflare pros

"The tool's profiling feature maps all the web application directories and related components on the profile directory. It has improved the security of my client's website applications."

"Imperva Web Application Firewall is a highly stable solution and is very mature."

"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 real time, you can see live traffic, which is flowing into our website."

"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."

"It's very pretty easy to onboard the URL."

"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."

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

More Imperva Application Security Platform pros

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

Cons

"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."

"There are some issues with the CDN services."

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"The analytics, basically the dashboard, doesn't have much to it."

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."

"An integrated SSO feature would be useful for Cloudflare DNS."

More Cloudflare cons

"There's always room for improvement. Occasionally, there might be false-positive alerts."

"It's quite expensive."

"The process to upgrade from one version to another can be a lot simpler than it is currently."

"The solution works for particular zones but isn't always the best solution for all zones."

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

"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."

"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."

"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."

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 product's pricing is cheap."

"That is one of the great features. I was able to access the majority of the features and services for free."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."

"There are no additional costs beyond the standard licensing fees."

"The price of the solution is expensive."

More Cloudflare pricing and cost advice

"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."

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

"Imperva Web Application Firewall's pricing is expensive."

"The tool is expensive."

"It is a very affordable solution."

"Pricing could be more competitive."

"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."

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