We'd like a dedicated account manager.
The responses are generally fast and effective.
The customer service is excellent, and I rate it ten out of ten.
Providing assistance almost instantly when needed.
Ensuring less than one second mitigation for L3/L4 and less than ten seconds for L7.

It is scalable and user-friendly.

Room For Improvement

Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
F5 BIG-IP AFM is costly, complex, needs dashboard improvements, enhanced features, better integration, and concerns over CPU and support.
Radware DDoS needs better scalability, integration, AI, documentation, interface, response, pricing, customization, SSL management, and support availability.
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.
Having advanced technology similar to other vendors like Palo Alto for zero-day attack prevention would be valuable.
The appliance and features could be enhanced further, especially in terms of security.
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.
F5 BIG-IP AFM is costly but justified by its features, with pricing for licenses and potential extra feature fees.
Radware DDoS offers effective security with flexible pricing, appealing to those prioritizing robust protection despite higher costs.
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.
The standard license is reasonably priced, but additional features like the WAF can be more expensive.
If considering a one-stop solution that provides load balancing, DNS security, AAA authentication, and firewalling on the same hardware, the cost is reasonable.
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.
We have a premium cost setup to align with a tier four uptime certified data center, storing and protecting critical infrastructure.
 

Valuable Features

Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
F5 BIG-IP AFM offers robust network security, ease of use, and supports cloud migration with AI-driven features.
Radware DDoS offers robust, automated protection with seamless integration, advanced analytics, and user-friendly features to enhance system stability.
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 solution provides behavioral analysis via AI to detect malicious traffic.
The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications.
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.

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.

Straightforward setup with very good granularity and performance
Our company uses the solution as a data center firewall.  It is hard to determine all users within our infrastructure. It depends on systems we put behind the solution. Its internal but also a data center firewall. Sometimes, there are hooks from the solution to our external infrastructure or…

Multi-layered defense ensures robust protection and optimized resources
Radware DDoS Protection Service is valued for its multi-layered defense protection, always-on and on-demand service, zero-day protection with adaptive behavioral-based mitigation, DNS and infrastructure protection, and SSL attack mitigation. The solution's multi-layer protection covers volumetric, protocol-based, and application layer attacks. They offer a very effective response against DNS attacks. Regarding behavior-based detection technology, in terms of real-time detection, it has been able to reduce false positives. We have pretty good experience with them. The geolocation is pretty good for an organization such as ours. We can block anything from certain regions, like North Korea or China, etc, cetera. It works alongside machine learning. They can update policies globally in less than ten seconds, which really helps with false positives. During a DDoS attack, it ensures legitimate users are not affected. We're working on a hybrid solution, so we have Defence Pro devices on our side and unlimited mitigation capabilities on the cloud.
