Room For Improvement

Imperva needs UI improvements, competitive pricing, better integration, real-time analytics, and enhanced support for efficiency and transparency.
Microsoft Azure Application Gateway is criticized for high costs, complexity, lacking documentation, and needing improvements in security, scalability, and support.
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.
Head of Sales Services Department at a comms service provider with 51-200 employees
One feature I mentioned is the support for non-HTTPS protocols such as TCP, which could allow one endpoint for all kinds of protocols.
Cloud Specialist at a tech services company with 10,001+ employees
Microsoft Azure Application Gateway has room for improvement because it offers many features, but its configuration is a bit difficult, at least from the developer point of view.
Cloud Head at White-Spunner & Associates
There is room for improvement in terms of support, such as assigning agents directly for more straightforward engagement.

Setup Cost

The Imperva platform's pricing is competitive with advanced features, ranging from $5,000 to $10,000 annually and no setup costs.
Microsoft Azure Application Gateway's cost is debated; appreciated for scalability but potentially expensive with additional fees compared to AWS.
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
Head of Sales Services Department at a comms service provider with 51-200 employees
We would prefer to have it cheaper, but it is still expensive.
Cloud Specialist at a tech services company with 10,001+ employees
Azure solutions are quite expensive.

Valuable Features

Microsoft Azure Application Gateway provides secure, efficient traffic management with integration, automation, and scalability benefits for straightforward application deployment.
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.
Head of Sales Services Department at a comms service provider with 51-200 employees
We are using it for some of the security features for our applications, particularly for securing traffic in transit with SSL.

The Web Application Firewall (WAF) in Microsoft Azure Application Gateway has been very effective in protecting applications from security threats.

We find mutual TLS valuable because we can verify the client securely by setting up the trust certificate of the client, and also if we do it at the client side as well.

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.

Mutual TLS has secured our web services and now needs broader protocol support
The most valuable feature we have found in Microsoft Azure Application Gateway is mutual TLS. We find mutual TLS valuable because we can verify the client securely by setting up the trust certificate of the client, and also if we do it at the client side as well. This successfully develops mutual trust, ensuring that we know the client who is calling our service is a legitimate client. That is a very nice feature.Microsoft Azure Application Gateway has helped manage our traffic efficiently because we have many web services that we can put behind the same URL, and we can have different URLs with the same Application Gateway with a limited number of listeners. We can do host-based routing as well as URL-based routing or path-based routing. It supports both, so we can have even a single URL supporting many applications, or we can have different URLs for different applications respectively. We have both use cases.
