Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Ifeanyi Stanly Nwokoro - PeerSpot reviewer
Has ensured ongoing protection against cyber threats and provides timely automated response while requiring improvements in cost structure and performance transparency
Business inherently involves risk, and it's important that services continue to improve. AWS Shield is not an exception. Regarding advanced Shield protection pricing, there should be cost protection for most DDoS events. The pricing model should be based on service usage rather than a flat monthly rate. The advanced technique package, while premium and not available to every user due to cost implications of $3,000 per month, offers valuable features including real-time attack visibility and 24/7 access to the DDoS response team. Integration is paramount, particularly with the Web Application Firewall's rule-based blocking paradigm that helps in balancing routes, especially route 53 and the global accelerator. AWS Shield uses pattern recognition to analyze traffic, and certain attributes are immediately intercepted. The assessment process is profound, and the service maintains consistent availability. From a software perspective, there are improvements needed regarding antivirus and network security. Additional engineering improvement requirements would benefit AWS Shield.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through
Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

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 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."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Centralized, full-featured DNS."
"The UI is good."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"The most valuable feature is its usability."
"The most valuable features of the solution are performance and security."
"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."
"It is quite scalable, and we have not faced any issues with its scalability."
"The product has a good mechanism to analyze trends and trigger events."
"I am impressed with the product's multiple features like security."
"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."
"The solution's ease of use is the most valuable feature."
"It is integrated with AWS. So, it gives you a good first step."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"AWS Shield offers numerous protection features that are crucial at the application layer, safeguarding users from distributed denial of service attacks, man-in-the-middle assaults, and hacker orchestrations."
"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."
 

Cons

"The solution could work at being less expensive. It costs a lot to use it."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Integration involving API with other products could be more user-friendly."
"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."
"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."
"The product needs to improve its logs and reports to make it read better."
"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."
"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."
"The time taken to detect anomalies must be reduced."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"The product is expensive."
"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."
"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
"We are using the free version."
"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."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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 solution is expensive when compared to other products but offers unlimited bandwidth."
"The price of the solution is expensive."
"The tool's pricing is good."
"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 cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"The tool is cheap."
