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.

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.

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 is a security SaaS provider that provides security and protects us from any application layer attack."
"The most valuable feature is the web application firewall."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"Imperva Web Application Firewall is stable."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"I would highly recommend Imperva Incapsula especially for customers who want extra security for their web presence."
"I am impressed with the product's automatic bot mechanism. It also gives us the control to create our own custom bot rules."
"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
"The availability of our sites, thanks to the load balance functionality, has improved, and it enables the site to be available all the time, despite people trying to attack it."
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"Incapsula has provided heightened visibility and awareness at management level on the actual threat landscape; it paves the way for easier approval for security-related implementations and projects."
"It seems to provide a bit of useful information on website health."
"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

"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 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."
"I rate technical support quite badly."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Cloudflare should add more documentation and pricing to the cloud version."
"There should be a specific price list for enterprise-level customers."
"Honestly the product has not really improved the way of my organisation."
"The product support needs to be accessible from more places, a wider area of coverage."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"Improve reporting interface and filtering."
"I miss being able to integrate the dashboard with other BI tools we are using. We have to export and import data to be able to present it, and doing so is a lot of work."
"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."
"If they can bring in generative AI features, that would be useful."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We are using the free tier of the solution."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The price of the solution is expensive."
"We are using the free version."
"I give the price a five out of ten."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"It's an excellent product, but it can be very costly."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"The price is high compared to other solutions like FortiWeb."
"It is not expensive compared to the other similar solutions in this category."
"The tool is expensive."
"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."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
