Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
We'd like a dedicated account manager.
The response time is very slow, especially when multiple teams are required to collaborate on a case.
Providing assistance almost instantly when needed.

I rate the scalability a ten out of ten.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
Scalability is well-supported by Radware.
It is scalable and user-friendly.

7.7
Cloudflare is generally stable and reliable, but occasional issues with downtime, speed, and DDoS protection are reported.

I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
In my opinion, there is no downtime experienced with Radware DDoS Protection Service due to external network redundancy.
 

Room For Improvement

Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
Azure DDoS Protection requires improved interface consistency, reporting, configuration simplicity, bandwidth optimization, enhanced services, and AI-driven auto-remediation.
Radware DDoS needs improved scalability, cloud integration, AI features, flexible configurations, better documentation, UI enhancements, and pricing adjustments.
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.
In future releases, one thing that would be great is if Cloudflare could provide basic WAF rules and security recommendations based on website scanning.
It would be beneficial to have more detailed insights available directly on the dashboard.
I have noticed some false positives with the Web Application Firewall yet not with DDoS Protection.
I suggest adding more services and additional services, which would be beneficial.
I suggest improvements to the user interface to make it easier to use and to find the necessary data for analysis.
I think Radware DDoS Protection Service could be improved by enhancing the network analytics features.
I want to improve the blocking time; it should be within 10 seconds because 18 seconds allows multiple transactions in the financial industry.
 

Setup Cost

Cloudflare offers flexible pricing with plans for small businesses to enterprises, balancing cost with comprehensive features and protection.
Azure DDoS Protection offers expensive but comprehensive protection with trial, special pricing for education, and no extra fees for some uses.
Radware DDoS Protection is costly but praised for flexible pricing, value, and effectiveness, especially for enterprises.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
It's cost-effective, but I think they should have a custom pricing model for enterprise customers based on the features you use.
If used with Front Door or Web Application Firewall, DDoS Protection is included without additional cost.
The pricing is somewhat costly, usually around $3,000 to $4,000 per month.
Compared to competitors, it is good.
Radware pricing is on the high end, suitable more for larger organizations.
I didn't check pricing of other providers in depth but verified with two, and found Radware to be significantly cheaper compared to F5.
 

Valuable Features

Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
Azure DDoS Protection offers seamless integration, robust security, and scalability, despite higher costs, providing significant ROI for vulnerable environments.
Radware DDoS Protection provides robust, user-friendly defense with real-time detection, automated mitigation, and reliable support to minimize downtime.
Our scenario consisted of two web servers in different allocations to control access demands, and the load balancer did the job as expected, bringing security and stability to access points.
For me, the valuable feature is DDoS protection.
The most valuable features of the solution are performance and security.
The security architecture with Azure DDoS Protection is critical for safeguarding our financial organization's infrastructure.
The ability to do research and development quickly without waiting for infrastructure is a plus.
The integration of various tools with Azure Firewall, like DDoS Protection, Web Application Firewall, and Azure Front Door, is quite effective.
The support from Radware is also exceptional, as they are always willing to jump on a call to help solve issues and improve our network design.
The ERT feeds, which are based on Radware intelligence services, have been beneficial to my organization because they block a lot of malicious IP addresses and botnets.
The best feature of Radware DDoS Protection Service is the automation.

Spencer Malmad - PeerSpot reviewer
It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Acts as an additional layer of protection, provides endpoint security but not very easy to configure
It's not very easy to configure, in my view. We have to do some work behind the scenes. It's not very simple. We have to do it very carefully, and we need to monitor this enablement as well. But apart from that, I didn't see any kind of challenges. So, in my opinion, configuration is the main trouble for them. It is something that can be done to be better. Not just configuration. You need an expert who knows the ins and outs of these security solutions. In my experience, people struggle with configuration. While configuring, we get this error, we get that error, and then we try to fix those issues. I have seen those. It's not straightforward.
Ajay Tyagi - PeerSpot reviewer
Successfully protects from DDoS attacks
The product is good, but the company could improve its services by appointing customer success managers. This would ensure better interaction with customers and help resolve issues on both customer and supplier ends. Most other security product companies such as Palo Alto and Forcepoint appoint customer success managers to interact with customers and ensure that the product they have purchased is used perfectly. If we are facing any kind of issues in using the product or service, the customer success manager should get things right.
