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.

Has enabled multi-layered threat mitigation but still lacks deeper visibility for advanced application attacks
AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods. It does not provide inherent protection against more sophisticated layer 7 attacks such as HTTP floods. In such cases, integration with WAF is necessary, which results in additional costs for customers. To protect layer 7, layer 4, and layer 3, customers must implement both solutions. The service also has difficulties with static detection thresholds, which may not be sensitive enough to detect smaller application-specific attacks. While AWS Shield is a key security service, AWS should enhance their expert support with 24/7 response for complex attacks, which is currently limited.

Strong policies and bot defenses have secured critical APIs and have reduced attack noise
From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.

Quotes from Members

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

Pros

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"It is very clear and the information is very useful."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"It is integrated with AWS. So, it gives you a good first step."
"AWS Shield offers numerous protection features that are crucial at the application layer, safeguarding users from distributed denial of service attacks, man-in-the-middle assaults, and hacker orchestrations."
"The product is easy to use."
"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."
"I am impressed with the product's multiple features like security."
"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."
"The product has a good mechanism to analyze trends and trigger events."
"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."
"The most important feature I have found to be the ease in how to do the backup and restores."
"Learning mode and custom policies are helpful features."
"An improvement has been to our website: It increases the speed of our response, the capacity of the site, and optimizes the bandwidth.​"
"Data masking is the most valuable feature of this solution."
"It has helped a lot with working among, and creating a link between, different teams in my organization, of course I’m referring to security, networking and system application teams."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"Based on my experience, and what I know this product can do, I would never recommend another solution."
"Integration with IBM AS/400 and Db2 is okay."
 

Cons

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"There should be a specific price list for enterprise-level customers."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"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 would like to not need a separate server for non-www redirection under the CNAME setup option."
"The pricing could be improved."
"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."
"Perhaps the time required to detect anomalies can be reduced."
"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."
"The product is expensive."
"The product should give users more flexibility to customize their security policies according to their requirements."
"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."
"The product needs to improve its logs and reports to make it read better."
"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."
"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."
"There could be some limitations 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."
"Licensing should be improved. Most of the clients aren't happy. It's expensive."
"Although we're only using it for the accelerator part, the purging of files and the way this feature functions could use improvement."
"Their customer service sometimes has different responses for similar requests. We sometimes need to explain the issue many times before they understand."
"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail."
"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."
"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."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The tool is a premium product, so it is very 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."
"The price of the solution is expensive."
"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 product's pricing is minimal compared to other products."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The cost primarily depends on the size of the organization."
"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."
"We pay $3000 per month for the solution."
"The tool is cheap."
"The tool's pricing is good."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"It is expensive."
"The price of this solution is a little bit high compared to competitors."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"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."
"The tool's pricing is good."
"We are satisfied with the pricing."
"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."
