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.

Pre Sales at a computer software company with 51-200 employees
Has provided exceptional performance for handling high web traffic
In my opinion, Windows Azure CDN is one of the best CDNs. We tried to replace it and made a business case to check other options such as Cloudflare, and we are using Cloudflare and tried Akamai, wanting to explore alternatives from OCI. One of the best features of Windows Azure CDN is that it has integrated WAF; it is not only CDN alone and it is a very smart and capable WAF. Windows Azure CDN is easily integrated with Azure services such as Azure Storage and Azure Web Apps, and sometimes we are using just Azure Front Door while the back end and database will be on OCI. The impact of Windows Azure CDN's dynamic content acceleration on our application performance is very significant. For one of our clients, we could not use anything other than Azure Front Door.

Quotes from Members

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

Pros

"The UI is good."
"It is a fast and secure DNS."
"Stability is great; I love their mechanisms, I love their GUI, I love their front end, I love their behind the scenes, algorithms and everything, it all makes sense."
"The setup and configuration is also easy to perform and their support is excellent."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"From what I've seen so far, there are no negatives to report as of yet"
"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."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Imperva is really amazing, feature wise and performance wise."
"Human contact Fast SLA Trustworthy and excellent communication Highly-functional back office with user friendly reports and intelligence on bad IPS and malicious software is at very high level and very quick."
"Gives us the ability to trace each connection, and to have logs to be able to differentiate between a positive and a false-positive intruder action."
"This product is a reliable defense from malicious attacks on a network environment."
"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
"Imperva Application Security Platform positively impacts us because we have a critical website, so by placing a WAF of Imperva's quality, it allows us to have visibility and granular control over the various attacks that can occur on the website."
"Without tuning, it blocked 88 percent of the vulnerabilities, and when we tuned it, it blocked 98 percent."
"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
"The most valuable feature of Windows Azure CDN is its effectiveness."
"I enjoy engaging in discussions with colleagues possessing unique expertise. I leverage the three platforms—Azure, Google, and AWS extensively. This allows me to offer diverse solutions to customers, commonly referred to as a multi-cloud approach."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"One of the best features of Windows Azure CDN is that it has integrated WAF; it is not only CDN alone and it is a very smart and capable WAF."
"We use the product for faster content delivery with low latency."
"It is a stable solution."
"One of the most valuable aspects is the capability to store extensive datasets and objects in the cloud, enabling their download through shared access signatures."
"One of the tool's best features is its ability to handle edge cases. For instance, we encountered a situation where we needed to remove certain files from public access. The solution offered a purge feature that allowed us to remove these files. This feature ensured that the files were deleted from all edge servers. Subsequently, we were able to upload new versions of the files."
 

Cons

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"I rate technical support quite badly."
"Integration involving API with other products could be more user-friendly."
"The analytics, basically the dashboard, doesn't have much to it."
"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."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The installation was complex until I learned what I had to learn."
"The signature updates could be faster."
"Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient."
"One improvement I would like to see in Imperva Application Security Platform is the ability to fail over to different sites for my same application."
"Reporting and the main Sites dashboard could use refinement."
"It would be nice to have more security control over mobile applications so I would suggest adding more mobile security features. It would also be beneficial to see improvements in regards to interface bandwidth performance, CPU time, and RAM size. Learning capability of the device is quite weak."
"Clients also often complain about the cost of the 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."
"If they can bring in generative AI features, that would be useful."
"I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"They should include configuration for cache rules."
"We have experienced issues with switch connectivity."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"I aim to enhance the reporting."
 

Pricing and Cost Advice

"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."
"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."
"We don't have any issues with the price."
"The price of the solution is expensive."
"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."
"The product's pricing is cheap."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"Pricing could be more competitive."
"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."
"The license is on a yearly basis."
"It's an excellent product, but it can be very costly."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"The tool is expensive."
"We are satisfied with the pricing."
"The pricing is extremely high, almost 9 out of 10."
"I rate the price of Windows Azure CDN a six on a scale of one to ten, where one is cheap, and ten is high."
"The tool's pricing is cheap."
"The tool's pricing is cheap."
"The solution's price is above the medium range."
"It comes at a relatively affordable cost."
"The solution's price depends on how much traffic you have. So, it was okay for us. Payments are to be made on a monthly basis since one has to pay for what they used."
"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."
