AWS WAF vs Cloudflare Web Application Firewall comparison

Cloudflare is a highly-regarded Content Delivery Network (CDN) and a Distributed Denial-of-Service (DDoS) protection solution. The robust global connectivity cloud platform that is Cloudflare ensures users are able to connect to the Internet quickly, securely, and reliably. Cloudflare is one of the world's largest networks in the marketplace today. Using Cloudflare, businesses, educational entities, NGOs, vloggers, bloggers, and anyone else with an internet presence can experience more secure, faster websites and applications.  

Currently, there are millions of Internet locations on Cloudflare, and the Cloudflare network 
continues to grow every day by the thousands. The solution is able to fulfill the requests for 
millions of websites seamlessly and serves on average 45 million HTTP requests per second.

Cloudflare has safe, secure data centers in close to 300 cities worldwide to ensure every 
client request is filled as quickly as possible. It is Cloudflare’s edge network that makes this 
possible by keeping content and other services as close to each client as possible, so the 
information requests are always only seconds away. 

Many organizations that work in democracy, civil society, human rights, or the arts are able to 
access Cloudflare's highest levels of protection for free via Project Galileo. Additionally, official 
election websites can be secured from hacking and fraud through Cloudflare’s Project 
Athenian, also at no additional cost.

Cloudflare can also help organizations of all sizes develop a robust zero-trust strategy to 
ensure the highest levels of productivity and profitability. Employees, stakeholders, and end users have a greater level of satisfaction and overall improved user experience, which can, in 
turn, result in higher revenues and overall ROI. Zero-trust and BYOD (bring your own device) 
access ensure end users and employees always have the best resources and technology 
available to them at all times.

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

AWS Web Application Firewall (WAF) is a firewall security system that monitors incoming and outgoing traffic for applications and websites based on your pre-defined web security rules. AWS WAF defends applications and websites from common Web attacks that could otherwise damage application performance and availability and compromise security.

You can create rules in AWS WAF that can include blocking specific HTTP headers, IP addresses, and URI strings. These rules prevent common web exploits, such as SQL injection or cross-site scripting. Once defined, new rules are deployed within seconds, and can easily be tracked so you can monitor their effectiveness via real-time insights. These saved metrics include URIs, IP addresses, and geo locations for each request.

AWS WAF Features

Some of the solution's top features include:

• Web traffic filtering: Get an extra layer of security by creating a centralized set of rules, easily deployable across multiple websites. These rules filter out web traffic based on conditions like HTTP headers, URIs, and IP addresses. This is very helpful for protection against exploits such as SQL injection and cross-site scripting as well as attacks from third-party applications.

• Bot control: Malicious bot traffic can consume excessive resources and cause downtime. Gain visibility and control over bot traffic with a managed rule group. You can easily block harmful bots, such as scrapers and crawlers, and you can allow common bots, like search engines and status monitors.

• Fraud prevention: Effectively defend your application against bot attacks by monitoring your application’s login page with a managed rule group that prevents hackers from accessing user accounts using compromised credentials. The managed rule group helps protect against credential stuffing attacks, brute-force login attempts, and other harmful login activities.

• API for AWS WAF Management: Automatically create and maintain rules and integrate them into your development process.

• Metrics for real-time visibility: Receive real-time metrics and captures of raw requests with details about geo-locations, IP addresses, URIs, user agents, and referrers. Integrate seamlessly with Amazon CloudWatch to set up custom alarms when events or attacks occur. These metrics provide valuable data intelligence that can be used to create new rules that significantly improve your application protections.

• Firewall management: AWS Firewall Manager automatically scans and notifies the security team when there is a policy violation, so they can swiftly take action. When new resources are created, your security team can guarantee that they comply with your organization’s security rules.

Reviews from Real Users

AWS WAF stands out among its competitors for a number of reasons. Two major ones are its user-friendly interface and its integration capabilities.

Kavin K., a security analyst at M2P Fintech, writes, “I believe the most impressive features are integration and ease of use. The best part of AWS WAF is the cloud-native WAF integration. There aren't any hidden deployments or hidden infrastructure which we have to maintain to have AWS WAF. AWS maintains everything; all we have to do is click the button, and WAF will be activated. Any packet coming through the internet will be filtered through.”
