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.

Solution ensures website availability and proactive threat mitigation
Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"I rate its stability a ten out of ten."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The API gives us the ability to remote control our DNS settings."
"So far I use free tier and happy with it."
"DDoS protection is this product’s most valuable feature."
"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."
"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."
"The most valuable feature is its usability."
"The most important feature I have found to be the ease in how to do the backup and restores."
"It blocks all types of attacks."
"The features that are most valuable are the protection against denial-of-service attacks and all kinds of other internet attacks."
"We're able to better manage network traffic with its analysis and security tools."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"Basic setup is simple but, as with any caching/WAF setup, there are tricks you need to learn, but it works really nice out of the box!"
"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."
"Incapsula can help to hide the real origin and provide access control over different pages, and it can protect the website from being attacked."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"The support team was helpful."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
 

Cons

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Honestly the product has not really improved the way of my organisation."
"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."
"Latencies are always a problem."
"I rate technical support quite badly."
"Technical support is lacking."
"The pricing could be improved."
"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."
"The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you."
"I needed some support and according to the SLA I couldn’t get telephone support and it took a little while till they got back to me."
"We had an issue when securing the web applications for DDoS protection."
"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."
"An Incapsula website configuration instance can be in a "Pending DNS changes" state, where further work is needing to be done by the customer, while website access is otherwise fully functional."
"The tool needs to include artificial intelligence and machine learning. It also needs to improve profiling."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"I don't really use it and therefore can't speak to areas of improvement."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
 

Pricing and Cost Advice

"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 version."
"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The cost primarily depends on the size of the organization."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is minimal compared to other products."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"It is expensive."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"We are satisfied with the pricing."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"The cost of this solution depends on the platform."
"Imperva Web Application Firewall's pricing is expensive."
"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
