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.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"Cloudflare consolidates various capabilities into one product, streamlining processes."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The solution provides good load balancing and protection against DDoS attacks."
"The solution is stable, and the DNS servers are simple to use."
"The most valuable feature of Cloudflare DNS is security."
"I rate its stability a ten out of ten."
"The tool is user-friendly."
"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."
"The most valuable features of Imperva Web Application Firewall are the monitoring of databases and the dashboards are easy to understand."
"It blocks all types of attacks."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"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."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"On the activity log, I can see the exact details, the visit, and the threat."
"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."
"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."
 

Cons

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"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."
"An integrated SSO feature would be useful for Cloudflare DNS."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"Cloudflare should add more documentation and pricing to the cloud version."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution."
"I would like to improve the tool's turnaround time in terms of support."
"There’s nothing that’s missing in terms of features."
"The UI interface needs improvement."
"Imperva Web Application Firewall is very expensive."
"The cost could be lower; our end clients need to have a high budget to purchase this solution."
"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 needs to be improved every time there are new attacks."
"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."
 

Pricing and Cost Advice

"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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 pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is cheap."
"A free version of the solution is available."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"Everybody complains about the price of this solution."
"We are satisfied with the pricing."
"It is not expensive compared to the other similar solutions in this category."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"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."
"Pricing could be more competitive."
"Imperva Web Application Firewall is expensive."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
