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.

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…

Quotes from Members

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

Pros

"The most valuable feature is the web application firewall."
"Their free account offers an awful lot of functionality and savings alone, before you get on to the minimal $20 a month for a Pro account which comes with its own great list of features."
"The setup and configuration is also easy to perform and their support is excellent."
"CloudFlare provides an answer to a variety of issues, so it gives you very high value for your money."
"From what I've seen so far, there are no negatives to report as of yet"
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"It is a fast and secure DNS."
"The API gives us the ability to remote control our DNS settings."
"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."
"I am impressed with the product's multiple features like security."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"The product is easy to use."
"It is quite scalable, and we have not faced any issues with its scalability."
"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 product has a good mechanism to analyze trends and trigger events."
"It is integrated with AWS. So, it gives you a good first step."
"I like the fact that the product provides a hybrid solution."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"It is a very efficient and robust appliance."
"The most important aspect, in general, is that the price is suitable for most clients."
"The DDoS protection features are valuable."
"This is a hybrid solution."
 

Cons

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"There should be a specific price list for enterprise-level customers."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"Cloudflare should add more documentation and pricing to the cloud version."
"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"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 product is expensive."
"The product should give users more flexibility to customize their security policies according to their requirements."
"The product needs to improve its logs and reports to make it read better."
"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."
"We end up having to pay extra for features that AWS adds that we don't need."
"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. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."
"Juniper is known in our country, but it is not very popular."
"It could use support in Spanish."
"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."
"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."
"The product must provide more Layer 7 capabilities."
"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."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
 

Pricing and Cost Advice

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"We don't have any issues with the price."
"The cost primarily depends on the size of the organization."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We are using the free version."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"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."
"We pay $3000 per month for the solution."
"The tool is cheap."
"The tool's pricing is good."
"Its price is normal."
"The price of Corero is affordable."
