For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
 

Customer Service

Sentiment score

Cloudflare's customer service is efficient for paying users, but responses can vary in speed and effectiveness for others.
Sentiment score
6.8
AWS WAF support is generally well-regarded but faces criticism for slow responses and limited flexibility, especially in lower tiers.
Sentiment score
6.1
Cloudflare's support is praised for responsiveness and effectiveness, though some Indian users face communication challenges and prefer local help.
This would help us address issues promptly, especially during unforeseen events like DDoS attacks.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
The key factor is the language in which the support is offered, which, in this case, is in Thai.
Resolving issues can take time because the support personnel may lack product expertise, leading to delays.
The technical support of Cloudflare Web Application Firewall rates between five and seven at maximum.

Cloudflare is praised for seamless scalability, managing enterprise-level traffic efficiently and earning high customer satisfaction during peak events.
Sentiment score
7.9
AWS WAF is highly scalable, effectively handling diverse needs and traffic load, earning positive feedback across multiple sectors.
Sentiment score
8.1
Cloudflare Web Application Firewall is praised for its scalability, flexibility, automation, and superior advantages compared to open-source solutions.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
The tool offers very good performance, even during high-traffic periods.
I rate the solution’s scalability an eight out of ten.
The scalability of Cloudflare Web Application Firewall rates between 8 to 9, as it depends upon the use cases and what exactly the client needs.
 

Stability Issues

Sentiment score
7.6
Cloudflare is widely regarded as stable and reliable, with improvements noted in uptime and performance on higher plans.

AWS WAF is consistently praised for its stability, reliability, and strong performance, with high ratings for dependable service.
Sentiment score
8.4
Cloudflare Web Application Firewall is highly stable and reliable, ensuring uninterrupted, effective protection and user satisfaction.
For DDoS protection, I would not recommend Cloudflare.
I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
In terms of reliability, I would rate AWS WAF about six out of ten due to the need for improved signature sets.
The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10.
 

Room For Improvement

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
AWS WAF needs better interface, automation, documentation, pricing, rules management, integration, threat detection, user support, and billing.
Cloudflare WAF must update features, improve documentation and support, reduce false negatives, and enhance usability, integrations, and visibility.
There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
Cloudflare should add more documentation and pricing to the cloud version.
Compared to firewalls, WAFs generally provide limited stateful analysis capabilities.
Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF.
The product can improve by having more multitenancy capability, which is currently not available.
They need to improve their support because getting a response for basic requests took around 48 hours, which is too long.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
AWS WAF's flexible and scalable pay-as-you-go pricing suits diverse needs, offering competitive rates compared to other vendors.
Enterprise users find Cloudflare's Web Application Firewall competitively priced, reasonable, and transparent despite starting fees and optional features.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
I think they should consider reevaluating the pricing for support, as it can be quite high.
Due to our status as an AWS shop, AWS WAF is cost-effective for us, and we benefit from discounts due to our extensive use of AWS services.
 

Valuable Features

Cloudflare enhances security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
AWS WAF offers scalable, user-friendly protection with advanced AI, DDoS defense, and seamless AWS integration at an affordable price.
Cloudflare WAF offers API configurability, comprehensive features, robust security, scalability, with strong integration and technical support.
The most valuable features of the solution are performance and security.
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
The cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services.
AWS WAF is not stateful, it offers a time-saving solution with its custom rulesets that enhance security and simplify management.
The custom rules and the geo-redundant geographical rule feature, which allows me to implement geographical rules for customers, add significant value.
The best features of Cloudflare Web Application Firewall are multiple, including the WAF, rate limiter, and bot attack protection.

Featured Reviews

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.
Kavin Kalaiarasu - PeerSpot reviewer
AWS's cloud-native security simplifies rule enforcement but needs better DDoS integration
The dashboarding could be improved, and the default metrics provided by AWS WAF could be upgraded. The rate at which AWS updates their managed rule sets could be better. Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF. Instead, they are part of AWS Shield. Providing DDoS protection as part of their WAF solution would be beneficial.
SachidDoshi - PeerSpot reviewer
Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.
