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.

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.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through

Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"In my opinion, CloudFlare is one of the best CDN networks I have ever used."

"It is easier to configure and develop documentation to see how we have configured firewalls."

"The most valuable features of the solution are performance and security."

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."

"Cloudflare has many features."

"I didn’t have to pay anything for better website security and reduced server load."

"The UI is good."

"Centralized, full-featured DNS."

More Cloudflare pros

"Customer Support has been the biggest help in dire situations."

"The solution's most valuable aspect is that it is easy to configure."

"We're able to better manage network traffic with its analysis and security tools."

"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 solution has a very good interface."

"Imperva makes it easier for us to put everything in code; we use Terraform to deploy our infrastructure."

"Automatic failover between primary and secondary sites enables high availability and accelerates disaster recovery."

"It is the best tool for detection and mitigation of current web-related attacks."

More Imperva Application Security Platform pros

"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."

"Scalability is awesome, and they have grown two folds or three folds since we started using them, with no concerns even as we protect close to 60,000 hosted sites for business and e-commerce customers."

Cons

"Cloudflare should add more documentation and pricing to the cloud version."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"Latencies are always a problem."

"Honestly the product has not really improved the way of my organisation."

"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."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"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 timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

More Cloudflare cons

"I would like to improve the tool's turnaround time in terms of support."

"Management of policies and rules can be complicated and the physical setup of the product has implications on HA."

"HTML minification could be improved. The actual HTML minification does not provide the maximum HTML minification nor provides the best result."

"They guarantee to fix your problem within 15 minutes, but they don’t always keep their word."

"We've had some issues with them in terms of response times, but overall they are okay."

"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."

"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."

"One potential improvement for Imperva is enhancing its alert system."

More Imperva Application Security Platform cons

"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."

"Genuine traffic coming in is still getting better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked."

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"That is one of the great features. I was able to access the majority of the features and services for free."

"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."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"The cost primarily depends on the size of the organization."

"We are using the free version."

More Cloudflare pricing and cost advice

"The solution's pricing is an issue."

"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."

"Although the pricing can be a little high, it is worth the protection and security that it offers."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."

"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."

"Imperva Web Application Firewall's pricing is expensive."

"The price is high compared to other solutions like FortiWeb."

"Varies depending on the needs of the customer."
