Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
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

"It is a fast and secure DNS."
"New and innovative way to protect the client's data."
"It's very user-friendly."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The tool is user-friendly."
"The most valuable feature of Cloudflare DNS is security."
"The solution is stable, and the DNS servers are simple to use."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"It protects web applications efficiently."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"There is a huge signature repository"
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"The WAF itself has been very valuable to me because it has such a complete range of features. Another reason why I like it is because it also takes care of the total overview of the traffic over the network."
"Learning mode and custom policies are helpful features."
"The solution is scalable."
"Imperva monitors all traffic, even customer access, to the web application. Then, Imperva uses features like signatures to identify attacks like cross-site scripting or SQL injection."
"The solution is stable."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"Very scalable and very stable firewall for web applications, with a good interface in its cloud version. Mitigation is its most valuable feature. The technical support for this product is also good."
 

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"There should be a specific price list for enterprise-level customers."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The reporting could be more granular."
"Its stability could be better."
"They have some limitations with third-party integrations."
"The dashboard could be more user-friendly."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The platform's control features related to real-time authentication and response time need improvement."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"The tool needs to improve CPU and storage memory."
"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."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"Support is one thing I wish Imperva could improve."
"Sometimes our web application firewall will slow down."
"I don't really use it and therefore can't speak to areas of improvement."
"The solution works for particular zones but isn't always the best solution for all zones."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"We don't have any issues with the price."
"The tool is a premium product, so it is very expensive."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"I give the price a five out of ten."
"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 pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"We pay $210 per month for CloudFlare WAF."
"The solution is expensive."
"It is not too pricey."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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"
"Imperva Web Application Firewall is expensive."
"It's an excellent product, but it can be very costly."
"Imperva Web Application Firewall's pricing is expensive."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"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."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"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."
