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

"From what I've seen so far, there are no negatives to report as of yet"
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"So far I use free tier and happy with it."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"We have seen a reduction in incidents and a good return on investment from Fortinet FortiAppSec Cloud, with our return on investment around 60%."
"Human contact Fast SLA Trustworthy and excellent communication Highly-functional back office with user friendly reports and intelligence on bad IPS and malicious software is at very high level and very quick."
"I was involved in the deployment and found that all the features in this product are fantastic, especially the correlated attack validation, threat radar (reputation, fraud), and virtual patching."
"Imperva DDoS is fairly stable, and its availability is quite high."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"Great product, it will not let you down!"
"The main benefit is the use case my clients find valuable, because for the product and security there is good API inspection, and if any abnormal API appears or there are any similarities due to changes, the API security features will catch that so allowed APIs will get access while others will be blocked."
"The solution's most valuable aspect is that it is easy to configure."
"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."
 

Cons

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"Support response time could be improved."
"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."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"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."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"Integration involving API with other products could be more user-friendly."
"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."
"Real-time traffic analysis has posed an issue for us because we did not see logs for legitimate traffic."
"I see some areas for improvement in Imperva Application Security Platform, especially regarding price."
"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."
"The solution should integrate with something that looks at continuous security management."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"I guess the GUI could be improved a little, as it’s not always simple to get."
"Caching rules are really basic now and lots of space for improvement here."
"Imperva Web Application Firewall is very expensive."
"The user interface could be better."
 

Pricing and Cost Advice

"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."
"We are using the free tier of the solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"A free version of the solution is available."
"We are using the free version."
"That is one of the great features. I was able to access the majority of the features and services for free."
Information not available
"There is a license or subscription renewal that our customers pay."
"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 solution's pricing is an issue."
"The solution's price is high for small companies."
"The tool is expensive."
"The price is high compared to other solutions like FortiWeb."
"There are a couple of different licensing models."
"It is a very affordable solution."
