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

"Centralized, full-featured DNS."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"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."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"DDoS protection is this product’s most valuable feature."
"The setup and configuration is also easy to perform and their support is excellent."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"Very intuitive and granular configuration - It does not require much time, or advanced knowledge, for configuration and maintenance."
"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."
"Provides Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner. These types of protection are valuable to the business due to the daily attacks on our portals, and that often cannot be seen without a tool like this."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"Essentially, it has added an extra layer of protection to my clients through their DNS routing service."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"The solution is stable."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"It seems to provide a bit of useful information on website health."
"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."
 

Cons

"The integration of LLMs on the dashboard is something that is needed in the tool."
"Integration involving API with other products could be more user-friendly."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"Cloudflare should add more documentation and pricing to the cloud version."
"The product needs to improve its automation."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"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."
"The product could use a broader scope in the area of policies."
"There is nothing specific where the application firewall is falling short."
"They need to work on the customer support; in my opinion, this is their weakest point. Some of their support representatives really have no idea how their service works."
"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"We faced challenges with high costs, as the customer perceived pricing for gateways to be excessive, but we handled multiple billing instances with sophisticated setups."
"Sometimes, support tickets don't get addressed quickly."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"A free version of the solution is available."
"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."
"We are using the free version."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The price is reasonable."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"It is not expensive compared to the other similar solutions in this category."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"Imperva Web Application Firewall is expensive."
"The solution's price is high for small companies."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"The cost of this solution depends on the platform."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
