Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Quotes from Members

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

Pros

"For businesses that don't have a dedicated security team, I think it's a better product; it's more intuitive for people like us."
"Because our website is blazing fast it improves our conversion rates."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"CloudFlare provides an answer to a variety of issues, so it gives you very high value for your money."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"I didn’t have to pay anything for better website security and reduced server load."
"The setup and configuration is also easy to perform and their support is excellent."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"We have researched them all, and it's a good solution all around."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"We've been completely satisfied with the product."
"The product allows the users to adjust the thresholds."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The most important feature I have found to be the ease in how to do the backup and restores."
"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."
"Imperva is really amazing, feature wise and performance wise."
"I would encourage people to implement Imperva Incapsula, as it is a very mature, easy to use, and reliable solution."
"The setup of Imperva DDoS was easy and we are satisfied with the pricing."
"Incapsula can help to hide the real origin and provide access control over different pages, and it can protect the website from being attacked."
"Imperva makes it easier for us to put everything in code; we use Terraform to deploy our infrastructure."
"Imperva solutions are the best in terms of stability."
 

Cons

"Honestly the product has not really improved the way of my organisation."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"I would like to not need a separate server for non-www redirection under the CNAME setup option."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"There are some issues with the CDN services."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"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."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution can be a little more user-friendly and it can be more affordable."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"I would like to see analytics, big data."
"Sometimes our web application firewall will slow down."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"It is complicated to integrate the solution's on-cloud version with other platforms."
"Technical support is probably the biggest drawback."
"There’s nothing that’s missing in terms of features."
"The Imperva Web Application Firewall automations are good, but there is still room for improvement with them."
"I'd like it to work with Let's Encrypt."
"Sometimes, support tickets don't get addressed quickly."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The product's pricing is minimal compared to other products."
"I give the price a five out of ten."
"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."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The price of the solution is expensive."
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It is expensive."
"The solution's price is high for small companies."
"It is not expensive compared to the other similar solutions in this category."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
