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

"The technical support is good."
"It's very user-friendly."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The most valuable feature is its usability."
"The solution is stable, and the DNS servers are simple to use."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"The solution can scale."
"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."
"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."
"Data masking is the most valuable feature of this solution."
"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"Imperva Web Application Firewall is stable."
"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."
"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."
"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
"Provides mobile app security."
"The best thing about Reblaze, for us, is that it has been a game changer because previously, we were using Google's Web Application Firewall, but it wasn't up to the mark."
"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 main feature is using the rules and being able to see the traffic. It helps us find malicious traffic."
"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."
"We like the website protection. It's really good. The dashboard is really simple to use."
 

Cons

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Integration involving API with other products could be more user-friendly."
"The solution could work at being less expensive. It costs a lot to use it."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"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."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"The documentation could improve for Cloudflare DNS."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Imperva Web Application Firewall could improve the API integration. It was complex for us. Additionally, The onboarding could be better."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"There is nothing specific where the application firewall is falling short."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"The solution works for particular zones but isn't always the best solution for all zones."
"I would like the solution to improve its support response time."
"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"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."
"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."
"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."
"Some of the settings on the dashboard are confusing."
"It would be beneficial if it had a workflow or a feature that could fine-tune settings based on high-level requirements."
"The next release should have next-generation automation."
"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."
"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."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"The price of the solution is expensive."
"The cost primarily depends on the size of the organization."
"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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 solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"The cost of this solution depends on the platform."
"The tool is expensive."
"There is a license for this solution and we purchase the license annually with no additional fees."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"There are a couple of different licensing models."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"It's an excellent product, but it can be very costly."
"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."
"I believe that for the six instances we have right now, it's costing us $16,000 per month."
"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."
"On a monthly basis we pay $750."
