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.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

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

"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"The most valuable feature of Cloudflare DNS is security."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"It is a fast and secure DNS."
"Cloudflare is very straightforward."
"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."
"In my opinion, CloudFlare is one of the best CDN networks I have ever used."
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product's initial setup phase is straightforward."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"The product helps our organization to access sites located in different regions quickly."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"The solution has a very good interface."
"It has threat intelligence and we are using Incapsula. With threat intelligence, we can separate HTTP and HTTPS traffic. We can use Incapsula to send all the threat intelligence to the WAF."
"Learning mode and custom policies are helpful features."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"With acquisition of a license to use the product, we received the ability to standardize database scanning and data protection across the enterprise around one product."
"This solution has helped in securing our clients' assets, which is key."
"The bot management features are very effective, as they help filter unwanted traffic using keywords."
"This product is a reliable defense from malicious attacks on a network environment."
 

Cons

"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."
"Latencies are always a problem."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"Fastly's customer service area needs improvement."
"Support is not that great."
"The solution's pricing could be better."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"What I don't like about Fastly is that they charge a heavy price."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"The product should provide improved bot detection and management."
"Their portal is very limited and needs improvement."
"HTML minification could be improved. The actual HTML minification does not provide the maximum HTML minification nor provides the best result."
"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."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"Analytics in the area of risk need to be improved to supply more information to the users for creating better environments."
"Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"I'd like it to work with Let's Encrypt."
 

Pricing and Cost Advice

"The price is reasonable."
"A free version of the solution is available."
"The product's pricing is cheap."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"We are using the free tier of the solution."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"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 price of the solution is expensive."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"It is an expensive solution."
"Fastly is less expensive than one of its competitors."
"You need to pay a premium price for the tool."
"The pricing has been very competitive."
"The solution is cheaper than other products in the market."
"In my opinion, Fastly is priced competitively."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"Imperva Web Application Firewall is expensive."
"It's an excellent product, but it can be very costly."
"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."
"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."
"Everybody complains about the price of this solution."
"The solution's price is high for small companies."
"Varies depending on the needs of the customer."
