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.

Has enabled multi-layered threat mitigation but still lacks deeper visibility for advanced application attacks
AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods. It does not provide inherent protection against more sophisticated layer 7 attacks such as HTTP floods. In such cases, integration with WAF is necessary, which results in additional costs for customers. To protect layer 7, layer 4, and layer 3, customers must implement both solutions. The service also has difficulties with static detection thresholds, which may not be sensitive enough to detect smaller application-specific attacks. While AWS Shield is a key security service, AWS should enhance their expert support with 24/7 response for complex attacks, which is currently limited.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Quotes from Members

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

Pros

"The setup and configuration is also easy to perform and their support is excellent."
"This solution has improved the security of our organization."
"The DDoS protection is the most valuable aspect of the solution."
"I rate its stability a ten out of ten."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."
"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."
"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."
"The product is easy to use."
"It is integrated with AWS. So, it gives you a good first step."
"I recommend AWS Shield because it has proven helpful in tracking DDoS attacks within both my past and present environments, and without AWS Shield, a business could face potential losses, as this tool helps in identifying and mitigating fake traffic that disrupts applications, ultimately supporting business continuity."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"It is quite scalable, and we have not faced any issues with its scalability."
"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."
"It is a user-friendly product in terms of monitoring and updating policies."
"The product allows the users to adjust the thresholds."
"I find the interface easy to use."
"Packet inspection has been effective for mitigating DDoS attacks."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"The product's initial setup phase was really easy."
"The solution is very user-friendly and very easy to use."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
 

Cons

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"Cloudflare should add more documentation and pricing to the cloud version."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"I think they have failed with their technical support."
"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."
"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"The pricing could be improved."
"We end up having to pay extra for features that AWS adds that we don't need."
"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"The product needs to improve its logs and reports to make it read better."
"The product should give users more flexibility to customize their security policies according to their requirements."
"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."
"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."
"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it."
"The web interface could be much better."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see analytics, big data."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"Earlier versions of firmware had bugs that limit my options."
"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."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
 

Pricing and Cost Advice

"The price is reasonable."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"We are using the free tier of the solution."
"A free version of the solution is available."
"We pay $3000 per month for the solution."
"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"The tool's pricing is good."
"The tool is cheap."
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
