Room For Improvement

Cloudflare's Web Application Firewall requires ModSecurity upgrades, improved logging, integration, accuracy, more controls, and better documentation.
Microsoft Azure Application Gateway is criticized for high costs, complexity, lacking documentation, and needing improvements in security, scalability, and support.
NetScaler needs improvements in usability, stability, security integration, and support while enhancing documentation, pricing transparency, and deployment processes.
The product can improve by having more multitenancy capability, which is currently not available.
Network Architect at a computer software company with 11-50 employees
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.
Owner at Hga consulting
They need to improve their support because getting a response for basic requests took around 48 hours, which is too long.
IT Manager at Amla Commerce
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
In future releases of Microsoft Azure Application Gateway, I would like to see more AI functionalities and a better dashboard as well as some customizations.
IT Manager at Chong Hua Hospital
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
 

Setup Cost

Cloudflare's WAF offers competitive pricing from $20 to $10,000, seen as cost-effective but could improve transparency.
Microsoft Azure Application Gateway's cost is debated; appreciated for scalability but potentially expensive with additional fees compared to AWS.
NetScaler pricing is high but offers strong features; cost-saving options include alternatives or negotiating multi-year subscriptions.
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.
Information Security and Compliance Officer at Carnation
When it comes to pricing for Microsoft Azure Application Gateway, I would rate it a seven out of ten.

Valuable Features

Cloudflare Web Application Firewall provides scalable DDoS protection, configurable rules, advanced features, and comprehensive support with minimal false positives.
Microsoft Azure Application Gateway provides secure, efficient traffic management with integration, automation, and scalability benefits for straightforward application deployment.
NetScaler provides flexible deployment, security enhancements, and integration with Citrix for efficient application delivery and robust traffic management.
The custom rules and the geo-redundant geographical rule feature, which allows me to implement geographical rules for customers, add significant value.
Network Architect at a computer software company with 11-50 employees
All the DNS and everything is routed through Cloudflare, so anybody coming to any of the sites has to go through Cloudflare first, making them the first wall of defense.
Owner at Hga consulting
The best features of Cloudflare Web Application Firewall are multiple, including the WAF, rate limiter, and bot attack protection.
IT Manager at Amla Commerce
We are using it for some of the security features for our applications, particularly for securing traffic in transit with SSL.
Information Security and Compliance Officer at Carnation
The Web Application Firewall (WAF) in Microsoft Azure Application Gateway has been very effective in protecting applications from security threats.

The gateway's Web Application Firewall feature enhances security as it is the first entry point to your network from the outside world.

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.

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.

Offers better visibility into user sessions compared to other solutions
Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.
