Room For Improvement

Cloudflare's Web Application Firewall requires ModSecurity upgrades, improved logging, integration, accuracy, more controls, and better documentation.
Imperva needs UI improvements, competitive pricing, better integration, real-time analytics, and enhanced support for efficiency and transparency.
Radware Alteon needs improvements in automation, user interface, customer support, integration, security, and educational resources to enhance competitiveness.
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.

They need to improve their support because getting a response for basic requests took around 48 hours, which is too long.

Maybe Imperva DDoS could use endpoints to get information about the attacks before they commence from the endpoint level or establish cooperation with endpoint vendors to share this information.

They keep integrating new features that sometimes break our production, but we use clustered systems, so we can test those software releases.

Setup Cost

Enterprise buyers favor Radware Alteon for its competitive pricing, strong performance, and flexible, simple licensing options.
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.

Effectively protects clients from automated threats and ensures global security
I cannot say much about areas of improvement for Cloudflare Web Application Firewall because I haven't gone through deep understanding of it, as I am still learning. However, they need to improve their support because getting a response for basic requests took around 48 hours, which is too long. If I took 48 hours to answer a request at my company, it would be a tough time to see or address the issue, and it would be frustrating.

Solution ensures website availability and proactive threat mitigation
Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

Manages SSL load balancing and offload efficiently while providing excellent support
The most valuable feature is the support from the engineering team. They quickly resolved a VLAN issue that other vendors could not. The product allows us to manage multiple networks and VLANs into a single box and add numerous web services and farms efficiently. The SSL management and integration capabilities are also standout features.
