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.
Lilian Blaitt - PeerSpot reviewer
Efficiently identifies and addresses vulnerabilities while providing robust protection
It is a secure tool. It is user-friendly and easy to work with. It is possible to easily find vulnerabilities with the WAF. I understand that the return is good since I haven't had any significant attacks. The vulnerabilities I found were easy to close. I think the return is good. It is a good tool.
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

"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The most valuable feature is its usability."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"The DDoS protection is the most valuable aspect of the solution."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"I like Cloudflare's application gateway and DDoS protection."
"The solution is stable, and the DNS servers are simple to use."
"Fortinet FortiWeb offers a variety of protections, including machine learning that helps protect web applications."
"It is user-friendly and easy to work with."
"The stability of the solution is excellent."
"The company provides technical support, and they are mostly available 24/7."
"The technical support is really good."
"It is a secure tool."
"I rate the overall solution ten out of ten."
"DDoS protection and WAF are the most valuable features. It is easy to deploy a service. It is easy and quick to deploy to a new website."
"The most valuable features are DDoS protection."
"Gives us the ability to trace each connection, and to have logs to be able to differentiate between a positive and a false-positive intruder action."
"The solution is very good at intercepting traffic before it gets to our data centers."
"The solution's most valuable aspect is that it is easy to configure."
"Imperva has a complete picture of how the applications are utilizing it. It is handy. DDoS is good. It has an internally managed database. It is very easy to integrate. We have integrated it with SIEM services."
"An improvement has been to our website: It increases the speed of our response, the capacity of the site, and optimizes the bandwidth.​"
"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."
 

Cons

"Latencies are always a problem."
"The analytics, basically the dashboard, doesn't have much to it."
"The product needs to improve its automation."
"Integration involving API with other products could be more user-friendly."
"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."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"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."
"The usability of the interface could be improved as it is not user-friendly."
"I do not have any notes on improvement."
"The only thing I encountered was related to integration, mostly concerning translation."
"The usability of the interface could be improved as it is not user-friendly."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
"I think that better bot protection is needed in this solution."
"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
"Imperva should have more points of presence in Africa."
"If they can bring in generative AI features, that would be useful."
"Imperva Web Application Firewall is very expensive."
"There is nothing specific where the application firewall is falling short."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is cheap."
"There are no additional costs beyond the standard licensing fees."
"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."
"The cost primarily depends on the size of the organization."
"The tool is a premium product, so it is very expensive."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
Information not available
"The cost of this solution depends on the platform."

"The license is on a yearly basis."
"It is a very affordable solution."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
