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.
PF
Exceptional resilience and protection well-suited for medium to large businesses
The initial setup process is quite straightforward. Its complexity largely depends on the intricacies of your platform. If your platform spans multiple sites across the globe, requiring configuration of multiple instances and traffic routing, it can become more intricate. From our experience, even in companies with extensive platforms, the configuration process remains relatively simple. Once the instances are spun up and the initial configurations are in place, you can use their console application to set up your site or sites for traffic management. This involves configuring the sites and uploading SSL certificates. Even for those not well-versed in the intricacies of networking layers and rules, the out-of-the-box configurations already provide solid protection.

Quotes from Members

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

Pros

"Easier http to https redirect using page rules"
"I rate its stability a ten out of ten."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"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 of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"Cloudflare has many features."
"The solution offers the flexibility to control configuration rules."
"The technical support is good."
"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
"Protection is the best solution since it has profile functionality."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"It has fewer false positives"
"Imperva Web Application Firewall is stable."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"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 feature I find most valuable is the user-friendly dashboard. It is easy to understand how everything works and it allows you to make decisions quickly and efficiently."
"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
"We like the website protection. It's really good. The dashboard is really simple to use."
"I very much like the elastic search and reports, allowing us to have a 360-degree view of the customer's activities and enabling us to track down any suspicious bots."
"Reblaze knows how to manage security. For me as, someone who knows little about security, it's good that I have a firm that optimizes everything according to their standards. It's their responsibility and they are fully hands-on."
"The real-time monitoring and reporting are very good. There are information updates in their portal every two minutes. They also have the ability to spill it into Sumo Logic, for example. It's very easy to use."
"The main feature is using the rules and being able to see the traffic. It helps us find malicious traffic."
"Provides mobile app security."
 

Cons

"Technical support is lacking."
"The documentation could improve for Cloudflare DNS."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"The product support needs to be accessible from more places, a wider area of coverage."
"Cloudflare's console should be made more user-friendly."
"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."
"Support is one thing I wish Imperva could improve."
"Imperva Web Application Firewall is very expensive."
"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."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"The solution works for particular zones but isn't always the best solution for all zones."
"The tool's UI is complicated. It would be best to have a more accessible UI dashboard to make the job easier."
"Sometimes our web application firewall will slow down."
"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
"The next release should have next-generation automation."
"The WAF features are not as granular as we would expect from a WAF system. There should be more granularity and in-depth rules, out-of-the-box."
"Up to now the only cons I could find is sometimes getting change management back on track, because it's a company that evolves, and sometimes I don't have the same needs that they have. But besides that, up until now, I am really pleased with their service and I've also recommended them to some of my clients."
"It would be beneficial if it had a workflow or a feature that could fine-tune settings based on high-level requirements."
"They have an interface that you have to adjust to. That is a bit of a downfall because I expect an interface to be very intuitive for someone who knows little about security. But if you know about security, the interface is wonderful."
"We have multiple products behind different instances of Reblaze. We have one instance for staging and then we have a production instance for multiple products. One of the things that we have requested is a unified view panel, so that we can see each of the instances in a unified view. That way, we won't have to go bouncing from instance to instance."
"I would like to have seen more automated reports. Maybe it has been improved in the last year and I'm just not aware of it. But from a managerial point of view, you want a summary report, a weekly report: How many attacks were blocked? How much bandwidth was saved due to the caching mechanism? What were the top-ten attacks that were tested on the network, etc? I could most likely have found all that data if I logged in to the system and ran different reports. It would be very helpful to get a management report on a weekly basis."
"There is room for improvement in helping us understanding session management... We want Reblaze to catch and identify everything. We want to see the various devices doing one activity and to see, in a timeline, what's happened. We would like to see a more human-readable display to understand what's happening in the web app."
 

Pricing and Cost Advice

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"A free version of the solution is available."
"The price is reasonable."
"The product's pricing is cheap."
"The price of the solution is expensive."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"We are using the free tier of the solution."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"Imperva Web Application Firewall is expensive."
"The tool is expensive."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"The solution's pricing is an issue."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"The price of this solution is a little bit high compared to competitors."
"There are a couple of different licensing models."
"I believe that for the six instances we have right now, it's costing us $16,000 per month."
"On a monthly basis we pay $750."
"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."
"There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town."
