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

"The DDoS protection is the most valuable aspect of the solution."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"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."
"I like Cloudflare's application gateway and DDoS protection."
"For businesses that don't have a dedicated security team, I think it's a better product; it's more intuitive for people like us."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"The most valuable feature of Cloudflare DNS is security."
"It is very clear and the information is very useful."
"​Technical support provides good, quick responses."
"It has fewer false positives"
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"The Web Application firewall is a valuable feature as the security features are mostly what we're interested in."
"The most valuable features for us are the DDoS and Bot."
"Imperva Application Security Platform has positively impacted my organization by making the website more secure."
"I would say compare it to other solutions in the marketplace feature by feature and see how Incapsula reporting and analytics dashboards compare and bot control compares – their solution for bot control is pretty good – and check those features with other enterprise level solutions, you get a lot for your money."
"Imperva Incapsula WAF is an awesome solution for implementing a WAF with good support and reliable hardware performance."
"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

"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."
"Latencies are always a problem."
"At the end, it is worth than giving your house keys to the NSA."
"The documentation could improve for Cloudflare DNS."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"Integration involving API with other products could be more user-friendly."
"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's a complicated tool to keep."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"Another area that could do with improvement is certificate management. I do not like the way that Incapsula handles certificates very much."
"The solution works for particular zones but isn't always the best solution for all zones."
"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."
"Customer Service: Average to poor. Technical Support: Average to poor."
"On the negative side, API security mainly supports cloud-based solutions, while most of my customers prefer on-prem setups, so achieving high performance with on-prem solutions would be beneficial."
"I would rate the solution as an 8 out of 10, simply because of the difficulty of operation management. It's a complicated tool to keep."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"We are using the free version."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"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 sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"The price of this solution is a little bit high compared to competitors."
"There are a couple of different licensing models."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"There is a license or subscription renewal that our customers pay."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
