Review summaries and opinions

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

ROI

Sentiment score
6.5
Cloudflare users experienced increased performance, security, and cost-effectiveness, leading to improved loyalty and revenue despite difficult ROI calculations.
Sentiment score
6.7
AWS WAF adds security, appreciated despite costs, by integrating with AWS to block attacks and protect investments effectively.
Sentiment score
3.9
Azure Web Application Firewall offers cost-efficiency through reduced administration, AI enhancements, and competitive pricing compared to leading competitors.
WordPress security can be tricky, and that's where Cloudflare can be absolutely helpful for small businesses.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
In terms of return on investment with Cloudflare, it costs my time to set them up, but basically once they're set up, it's done.
Recently, they have been under serious attack with major exploits, such as Log4j, affecting Fortinet and Palo Alto, and even Cisco and VMware.
AI-based recommendations save on time and money.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is quick, but technical support feedback is mixed, with improvement needed in responsiveness and detailed assistance.
Sentiment score
6.6
AWS WAF support is generally well-regarded but faces criticism for slow responses and limited flexibility, especially in lower tiers.
Sentiment score
7.1
Microsoft support is generally satisfactory, with users preferring higher-tier options for faster response and clearer communication.
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.
They are good at troubleshooting and configuring things.
I am very satisfied with the response from Microsoft dedicated architects if it happens that I have to call for their support.
I reached out to their support, and they helped me resolve the issue effectively.
 

Scalability Issues

Sentiment score
8.1
Users praise Cloudflare for seamless scalability, effective traffic management, easy upgrades, and robust global infrastructure without disruptions.
Sentiment score
7.8
AWS WAF is highly scalable, effectively handling diverse needs and traffic load, earning positive feedback across multiple sectors.
Sentiment score
6.6
Azure Web Application Firewall offers flexible, highly-rated scalability, easily adapting to traffic changes and various workload needs across subscriptions.
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.
Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup.
For our company, Azure Web Application Firewall works effectively for scalability.
 

Stability Issues

Sentiment score
7.6
Cloudflare is highly rated for stability and uptime, with few past issues, especially on higher-tier plans.
Sentiment score
8.3
AWS WAF is consistently praised for its stability, reliability, and strong performance, with high ratings for dependable service.
Sentiment score
7.1
Azure Web Application Firewall is highly stable, with minimal connectivity or performance issues and consistently earns high reliability ratings.
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.
We faced issues with AWS WAF when writing the custom rules.
Very rarely do I see any latency issues.
 

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
AWS WAF needs better interface, automation, documentation, pricing, rules management, integration, threat detection, user support, and billing.
Azure Web Application Firewall needs better reporting, integration, cost plans, and process streamlining for enhanced management and support.
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.
The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client.
Compared to firewalls, WAFs generally provide limited stateful analysis capabilities.
The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information.
Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF.
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
The pricing needs improvement, and I think for beginners it will be a little bit complicated, so the ease of use could be enhanced.
 

Setup Cost

Cloudflare offers scalable pricing, from free to enterprise plans, providing significant value especially for mid-sized companies.
AWS WAF's flexible and scalable pay-as-you-go pricing suits diverse needs, offering competitive rates compared to other vendors.
Azure Web Application Firewall offers scalable pricing, valued functionality, and favorable terms, appealing compared to AWS and GCP.
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.
The licensing cost for AWS WAF is just pay-as-you-go; it is a service-based model.
It is even a lower cost compared to AWS and GCP.
Sometimes, when opting for a higher SKU, it's not the WAF itself that's costly but the additional requirements.
I would place Azure Web Application Firewall at an eight on a scale from one to 10, with one being cheap and 10 being expensive.
 

Valuable Features

Cloudflare enhances performance and security with CDN caching, DDoS protection, and an easy-to-use dashboard, benefiting many users.
AWS WAF offers scalable, user-friendly protection with advanced AI, DDoS defense, and seamless AWS integration at an affordable price.
Azure Web Application Firewall offers robust security, seamless Azure integration, automatic rule management, and scalable, user-friendly deployment with minimal downtime.
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 biggest benefit of AWS WAF for us is to filter malicious requests, so we can protect our environment and application from malicious actors.
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.
With Microsoft, everything is within a single suite, making it easier to configure and plan.
It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure.
It integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot.

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.
Azam S M - PeerSpot reviewer
Has successfully filtered malicious traffic and allowed country-specific access controls
For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.
Mano Senaratne - PeerSpot reviewer
Comprehensive suite simplifies configuration while frequent updates require management
Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.
