Room For Improvement

Cloudflare users seek better analytics, integration, support, pricing clarity, and enhanced features like caching and multi-user access.
F5 Advanced WAF requires intuitive UI, clearer reporting, seamless updates, better integration, and improved support with advanced features.
Imperva DDoS requires improvements in customer support, pricing, interface design, security features, latency management, and enhanced documentation.
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 ability to integrate with the on-site active directory instead of just AD through Azure AD
Deployment training for F5 Advanced WAF is lacking and restricts growth by being inaccessible and costly for partners.
 

Setup Cost

Cloudflare offers flexible pricing plans from free to $1,500 monthly, ideal for businesses of different sizes and traffic needs.
F5 Advanced WAF is costly but valued for robust features; pricing varies, challenging for small businesses yet negotiable.
Imperva DDoS offers competitive pricing with flexible options, but can be costly compared to Cloudflare or Akamai.
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.
Subscription models have competitive pricing, while perpetual licenses involve an upfront higher cost.
 

Valuable Features

Cloudflare enhances performance and security with CDN, caching, DDoS protection, easy DNS management, analytics, and intuitive interface.
F5 Advanced WAF enhances web security with anti-bot protection, behavior analysis, and flexible policy customization, featuring AI and load balancing.
Imperva DDoS provides robust, easy-to-use protection against attacks with advanced security measures and real-time traffic analysis.
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 perpetual license, despite an initial higher cost, lacks transparency regarding support expiration.

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.

Easy event identification, highly stable, and customizable
Generally, F5 Advanced WAF initial setup is straightforward. However, our environment was more complex and it took us a little more time to customize the solution to where we needed it to be. Additionally, the customization didn't rectify everything. We had to do customization to a certain event to prevent attacks that it wasn't catching, but that might not necessarily be the solutions' fault. It could be more of our setup than the solution's fault and not being able to run the latest version or the newer version could be more of a limitation on our ability to put it in the right place. The whole implementation to have the solution run at the level we wanted it to take approximately five months. Our company's environment is one that we can't put a canned solution in front of. Our environment, cannot have a canned solution that might fit everybody else because of how customized this environment is. It does need a lot of tuning to meet our environment's requirements. I rate the initial setup of F5 Advanced WAF a three out of five.

I like the content monitoring feature which I haven't seen in other WAF solutions.
They could improve by minimizing false positive results. Although this occurs less with Imperva, we would like to see some further improvements. We have been using this product for last 1 years, it's result is very impressive. But due to the excessive load on the Web site where thousands of requests‎ are generated from legitimate users, however the request in which any sequential or specialised characters are requested would be directly blocked by impreva . Currently imperva blocks the special character request generated from the user, as I conduct a test where I am parsing the encoded html values of the same special characters to the input field, imperva bypasses these encoded values for example : ' i.e. %27 or / i.e %2F, the WAF bypasses these encoded characters. I hope that this device should have a capability to detect the pattern which is associated with Xss or Xsrf, rather then by not blocking the request which contains any special characters.
