Featured Reviews

SachidDoshi - PeerSpot reviewer
Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.
Mitesh D Patel - PeerSpot reviewer
Effectively defends against threats like cross-site scripting (XSS), SQL injection, and others
It does bring value. For example, consider a BFSI customer. Their application is critical and represents their brand. Without a WAF, an attack could take their application down, harming their reputation. It leads to hampering the customer's workflow. With an Imperva WAF, they protect against attacks like DDoS or SQL injection, ensuring their application remains available and customers are happy. That's the main benefit for both the customer and the organization. The impact depends on the customer's use case. If their business primarily operates online, a CDN is beneficial for traffic optimization. Moreover, the integration options depend on the specific use case of our customers. Generally, integration capabilities are good with SIEM (Security Information and Event Management) parts.

Quotes from Members

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

Pros

"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"The initial setup process is simple."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"The security features are valuable. The particular feature we use is called OWASP."
"The product has a valuable security control functionality."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"It is configurable via API."
"Configuration for different application sources is most valuable. We can segregate the traffic that an application is carrying and identify the sizing in Imperva."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."
"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."
"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."
"The solution integrates seamlessly with other tools and has a good alert mechanism."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
 

Cons

"Cloudflare Web Application Firewall should include port forwarding features."
"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."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"They have some limitations with third-party integrations."
"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."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The solution's learning curve can still be further reduced"
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"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."
"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."
"I'd like the option to pick your bot protection."
"I would like to improve the tool's turnaround time in terms of support."
"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"One potential improvement for Imperva is enhancing its alert system."
 

Pricing and Cost Advice

"The annual licensing fee is $10,000 USD."
"The solution is expensive."
"It is not too pricey."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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."
"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"
"There are a couple of different licensing models."
"There is a license for this solution and we purchase the license annually with no additional fees."
"The tool is expensive."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"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."
"Imperva Web Application Firewall's pricing is expensive."
"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."
"The price is high compared to other solutions like FortiWeb."

Questions from the Community

What do you like most about Cloudflare Web Application Firewall?
The product has a valuable security control functionality.
What is your experience regarding pricing and costs for Cloudflare Web Application Firewall?
Cloudflare is cheaper compared to Azure WAF, which I have considered before.
What needs improvement with Cloudflare Web Application Firewall?
The product can improve by having more multitenancy capability, which is currently not available. This improvement would enable managed service providers to implement it more effectively.
Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?
For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.
DDoS solutions: Any other solutions to consider aside from Radware DDoS Protection Service and F5 Silverline DDoS Protection?
You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperv...
