Executive SummaryUpdated on Oct 19, 2025

Cloudflare and AWS Shield compete in the security and content delivery network category. Cloudflare appears to have the upper hand with its emphasis on speed improvements and aggressive caching as well as its flexibility and customization capabilities through SSL and page rules, making it an attractive option for web performance optimization and security.

Features: Cloudflare's CDN speed improvements, aggressive caching, and flexible SSL offer enhanced security and performance. Its page rules and website analytics provide valuable customization and insights. AWS Shield excels in robust DDoS protection, focusing on application layer security. Its comprehensive WAF integration and targeted protection against advanced threats are notable.

Room for Improvement: Cloudflare users see room for improvement in analytics precision, CDN speed, and customer support responsiveness.

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.

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.

Quotes from Members

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

Pros

"I am impressed with the product's multiple features like security."

"The solution's ease of use is the most valuable feature."

"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."

"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."

"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."

"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 product is easy to use."

More AWS Shield pros

"The solution is stable, and the DNS servers are simple to use."

"Centralized, full-featured DNS."

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

"It is a fast and secure DNS."

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."

"The most valuable feature is its usability."

"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."

More Cloudflare pros

Cons

"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."

"The product should give users more flexibility to customize their security policies according to their requirements."

"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."

"We end up having to pay extra for features that AWS adds that we don't need."

"The product needs to improve its logs and reports to make it read better."

"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."

More AWS Shield cons

"Latencies are always a problem."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"In the last two years, there has been a certain amount of downtime when using the VDM."

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."

"An integrated SSO feature would be useful for Cloudflare DNS."

"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

More Cloudflare cons

Pricing and Cost Advice

"The tool is cheap."

"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 tool's pricing is good."

"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 product's pricing is minimal compared to other products."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"The cost primarily depends on the size of the organization."

"The product's pricing is cheap."

"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."

Reviews from real users

“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. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“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.” PeerSpot user, Competence Center Manager at a tech services company
