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.

Web protection has improved security posture and prevents advanced bot and zero-day attacks
In my opinion, the best features of Fortinet FortiAppSec Cloud are usability and price, which are the two strongest features from Fortinet security products. We use the advanced bot mitigation, which supports credential stuffing, account takeover prevention, and stopping layer 7 DDoS and OWASP Top 10 attacks. With the bot mitigation in Fortinet FortiAppSec Cloud, we control end users whenever they connect to our website, checking that they are not bots and allowing access only after verification. We run AI detection in a testing phase, using both basic and advanced security measures, including API security and XML protection. AI helps by providing machine learning that suggests which policies need tuning and which signatures need to be added to our policy. Fortinet FortiAppSec Cloud's adaptability to traffic patterns helps mitigate zero-day vulnerabilities through machine learning. Fortinet FortiAppSec Cloud helps our organization by relying on Fortinet threat intelligence, which provides information on newly emerging zero-day attacks, allowing us to run signatures to stop these attacks. We utilize the dynamic learning capabilities for threat updates.

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

"Centralized, full-featured DNS."
"The technical support is good."
"The DDoS protection is the most valuable aspect of the solution."
"The tool is user-friendly."
"The most valuable feature is its usability."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The solution provides good load balancing and protection against DDoS attacks."
"I rate its stability a ten out of ten."
"We have seen a reduction in incidents and a good return on investment from Fortinet FortiAppSec Cloud, with our return on investment around 60%."
"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"Integration with IBM AS/400 and Db2 is okay."
"It has threat intelligence and we are using Incapsula. With threat intelligence, we can separate HTTP and HTTPS traffic. We can use Incapsula to send all the threat intelligence to the WAF."
"An improvement has been to our website: It increases the speed of our response, the capacity of the site, and optimizes the bandwidth.​"
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."
"It works right out of the box once you integrate the application."
"It is an effective threat mitigation tool."
 

Cons

"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"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."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"There might be helpful if there was some web application firewall feature."
"The pricing could be improved."
"Integration involving API with other products could be more user-friendly."
"Technical support is lacking."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"Real-time traffic analysis has posed an issue for us because we did not see logs for legitimate traffic."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers."
"The user interface could be better."
"The tool needs to include artificial intelligence and machine learning. It also needs to improve profiling."
"I would like to see automated reporting to improve visibility."
"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
 

Pricing and Cost Advice

"The tool is a premium product, so it is very expensive."
"The price is reasonable."
"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 cost primarily depends on the size of the organization."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"A free version of the solution is available."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We are using the free version."
Information not available
"The solution's pricing is an issue."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"Varies depending on the needs of the customer."
"The solution's price is high for small companies."
"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."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"It is not expensive compared to the other similar solutions in this category."
"It is a very affordable solution."
