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.

Quotes from Members

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

Pros

"CloudFlare has positively improved my site's speed, performance and security."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"I rate its stability a ten out of ten."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"It's very user-friendly."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The product's initial setup phase was really easy."
"The protection resources and the support are valuable features of the solution."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"We use it to protect our users and their data."
"It allows me to see all the traffic on my network."
"The product allows the users to adjust the thresholds."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."
"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping."
"The solution has a very good interface."
"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."
"The most valuable features for us are the DDoS and Bot."
"It is an effective threat mitigation tool."
"The WAF itself has been very valuable to me because it has such a complete range of features. Another reason why I like it is because it also takes care of the total overview of the traffic over the network."
"Well, just by using the security rules to block all secured areas by IP minimized the chance of sensitive data leaking outside."
 

Cons

"It looks like they don't support as many TLDs as other registrars, but since they are very new as a registrar, I expect this may improve soon."
"The solution could be more user-friendly."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"There should be a specific price list for enterprise-level customers."
"DNS Management."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"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."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"Earlier versions of firmware had bugs that limit my options."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The web interface could be much better."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"Alerts and reporting features must be improved."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution works for particular zones but isn't always the best solution for all zones."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"If they can bring in generative AI features, that would be useful."
"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 solution should integrate with something that looks at continuous security management."
"Their portal is very limited and needs improvement."
"The tool's UI is complicated. It would be best to have a more accessible UI dashboard to make the job easier."
"Caching rules are really basic now and lots of space for improvement here."
