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.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

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

Pros

"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."
"This solution has improved the security of our organization."
"Centralized, full-featured DNS."
"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."
"We're partners with Cloudflare; this solution is the best product and it does not charge you for any kind of attack on your traffic, only for good traffic, and it can mitigate up to 30 TBPS of DDoS attacks."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"This solution has helped in securing our clients' assets, which is key."
"I see valuable benefits from advanced detection and traffic profiling during DDoS attacks, and I track some metrics related to DDoS protection performance."
"Overall, I am really happy with this solution."
"I suggest others looking into using Imperva Application Security Platform consider it as the best solution."
"I would highly recommend Imperva Incapsula especially for customers who want extra security for their web presence."
"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."
"Customer Service: Excellent, they answered all our questions."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
"It seems to provide a bit of useful information on website health."
 

Cons

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"Latencies are always a problem."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"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."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"At the end, it is worth than giving your house keys to the NSA."
"We looked at CloudFlare. We tried it but it didn’t work that well."
"Sometimes, it takes a bit of time for the technical staff of the solution to get back to our company with a resolution for our problems."
"The tool needs to improve CPU and storage memory."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"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."
"Imperva DDoS does not provide version control."
"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."
"We've had some issues with them in terms of response times, but overall they are okay."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"We don't have any issues with the price."
"The price is reasonable."
"We are using the free tier of the solution."
"The cost primarily depends on the size of the organization."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"A free version of the solution is available."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"The tool is expensive."
"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 is a license or subscription renewal that our customers pay."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"There are a couple of different licensing models."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
