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.

Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

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

"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."
"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The solution is stable, and the DNS servers are simple to use."
"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The most valuable feature is its usability."
"It is a very efficient and robust appliance."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"This is a hybrid solution."
"I like the fact that the product provides a hybrid solution."
"Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner, are valuable to the business due to the daily attacks on our portals that often cannot be seen without a tool like this."
"The solution can be configured in just a couple of minutes."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"Compared to other web application firewalls in the market, Imperva does things in the most accurate way."
"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."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"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."
"The most valuable features of Imperva Web Application Firewall are the monitoring of databases and the dashboards are easy to understand."
 

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"The solution could use more analytics on the backend to give us more insights into everything."
"There might be helpful if there was some web application firewall feature."
"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."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Lacks international presence."
"The product must provide more Layer 7 capabilities."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
"It could use support in Spanish."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"Juniper is known in our country, but it is not very popular."
"It could use support in Spanish."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."
"The solution works for particular zones but isn't always the best solution for all zones."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"However, I'd like to be able to drill down more into the analytics that Incapsula collects."
"The signature updates could be faster."
"Incapsula: Allow easier scripting of firewall rules."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
 

Pricing and Cost Advice

"A free version of the solution is available."
"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."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The cost primarily depends on the size of the organization."
"The price of Corero is affordable."
"Its price is normal."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"Imperva Web Application Firewall is expensive."
"Imperva Web Application Firewall's pricing is expensive."
"There are a couple of different licensing models."
"It's an excellent product, but it can be very costly."
"Varies depending on the needs of the customer."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."
