Room For Improvement

Azure Web Application Firewall needs better reporting, integration, cost plans, and process streamlining for enhanced management and support.
Fastly requires improvements in China presence, configuration complexity, pricing, customer support, security features, documentation, and bot detection.
The product can improve by having more multitenancy capability, which is currently not available.

I think they're doing a good job with DNS and as support for any domains that I create or that my clients create, it's mandatory for me to ensure they have Cloudflare as their DNS provider.

And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network.

Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.

CTO at PlayNirvana
Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Offers robust analytics and seamless cloud integration with minor room for user interface improvement
The Microsoft support and the analytics are what I appreciate about Azure Web Application Firewall. 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. It helps when looking for threats. It reduces issues significantly because the filtering capabilities are high. Given that it's a cloud solution, we have very minimal downtime, especially because we have Microsoft support. On a scale of one to 10, I would give it an eight.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.
