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.
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.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

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

Pros

"New and innovative way to protect the client's data."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"Generally, I am satisfied with this product."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The solution is stable, and the DNS servers are simple to use."
"It is a fast and secure DNS."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"The solution has been quite stable. I have not seen any bugs at all."
"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"It mitigates all of the availabilities of risks around web applications."
"The solution is cloud-based and offers us good uptime. It has combined web and API security. Therefore, with one license, you access both application security and also API security."
"We can prevent attacks or issues even before they happen."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"Integration involving API with other products could be more user-friendly."
"Latencies are always a problem."
"There might be helpful if there was some web application firewall feature."
"There should be a specific price list for enterprise-level customers."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"Cloudflare should add more documentation and pricing to the cloud version."
"The analytics, basically the dashboard, doesn't have much to it."
"The support for the on-premises version needs improvement."
"The solution works for particular zones but isn't always the best solution for all zones."
"Their portal is very limited and needs improvement."
"I would like the solution to improve its support response time."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"I don't really use it and therefore can't speak to areas of improvement."
"One potential improvement for Imperva is enhancing its alert system."
"I'd like the option to pick your bot protection."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We are using the free tier of the solution."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"I give the price a five out of ten."
"The tool is a premium product, so it is very expensive."
"The cost primarily depends on the size of the organization."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"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."
"There are a couple of different licensing models."
"The solution's pricing is an issue."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"The cost of this solution depends on the platform."
"There is a license for this solution and we purchase the license annually with no additional fees."
