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.

Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

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.

Quotes from Members

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

Pros

"It is easier to configure and develop documentation to see how we have configured firewalls."
"It is very clear and the information is very useful."
"Generally, I am satisfied with this product."
"The most valuable feature is its usability."
"Centralized, full-featured DNS."
"The DDoS protection is the most valuable aspect of the solution."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"It's very user-friendly."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"The most important aspect, in general, is that the price is suitable for most clients."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"I like the fact that the product provides a hybrid solution."
"It is a very efficient and robust appliance."
"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."
"The DDoS protection features are valuable."
"The most important feature I have found to be the ease in how to do the backup and restores."
"Hands down, the WAF is the most valuable feature; being able to identify, block, whitelist or blacklist as needed, are all valuable."
"The Imperva Web Application Firewall feature I have found the most valuable is the ease of deployment."
"Overall, I am really happy with this solution."
"Imperva Application Security Platform positively impacts us because we have a critical website, so by placing a WAF of Imperva's quality, it allows us to have visibility and granular control over the various attacks that can occur on the website."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"The user-generated spam stopped after we started using Incapsula, and so we feel more secure."
"We can now quickly address the problems of our clients in an effective manner."
 

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"The product needs to improve its automation."
"I rate technical support quite badly."
"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."
"Cloudflare's console should be made more user-friendly."
"There should be a specific price list for enterprise-level customers."
"Juniper is known in our country, but it is not very popular."
"Lacks international presence."
"It could use support in Spanish."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"Reporting and the main Sites dashboard could use refinement."
"The solution works for particular zones but isn't always the best solution for all zones."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
"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."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"It would be nice to have a mobile app as a dashboard interface instead of the web administration, but the service is really great."
"This is a very limited tool if you're looking to customize."
"We need an improvement in the support. We need a lot of turnarounds."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The product's pricing is cheap."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The price of the solution is expensive."
"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 price of Corero is affordable."
"Its price is normal."
"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."
"There are a couple of different licensing models."
"We are satisfied with the pricing."
"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 price of Imperva Web Application Firewalls is expensive compared to others."
"Imperva Web Application Firewall is expensive."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
