Azure Front Door offers a quick return on investment once it is set up.
Co-Founder at arpa
They know how much money they are losing while the system is down, so by increasing the possibility of not having a down website or web application, return on investment can be calculated easily.

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
Azure Front Door needs improvements in multi-cloud support, pricing, user interface, DDoS protection, and enhanced functionalities as per feedback.
Imperva needs UI improvements, competitive pricing, better integration, real-time analytics, and enhanced support for efficiency and transparency.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
Managed Services Manager at Adapture Technology Group
Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements.
Senior Cloud Solution Architect at Integrated Technology Solution Group (ITSG)
There are some performance considerations when it comes to dynamic content that involves fetching data from databases or using APIs.
Senior Solutions Architect at Think Power Solutions
If I could use Azure Front Door with private IP addresses, it would be more beneficial.
Azure Consultant at cloudshift
It relies on the WAF module where users must configure rate-limiting rules, as it does not automatically sense malicious spikes in traffic.
Architect at a tech vendor with 5,001-10,000 employees
The only significant adjustment required is with URL set parameters that need to be passed for an existing domain.
Co-Founder at arpa
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.

I rate the product’s pricing a five out of ten, where one is cheap, and ten is expensive.

The tool is a premium product, so it is very expensive.

Owner at Hga consulting
Has helped manage client domains with streamlined access control and threat visibility
I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

Optimizing global application performance with robust security measures and advanced traffic management
DDoS capabilities in Azure Front Door could certainly be improved. Although Microsoft states it comes with basic DDoS protections out of the box, I find it often ineffectual in mitigating thousands of requests from a single source in a short span of time. User then have to rely on the WAF module where users must configure rate-limiting rules, as it does not automatically sense malicious spikes in traffic. I believe Front Door should have an out-of-the-box premium DDoS protection that can automatically detect and block malicious traffic. I would appreciate improvements in the turnaround time for support, especially since issues with Azure Front Door are usually critical for businesses. If there is an issue, it often results in downtime for line of business applications. I have faced this situation multiple times as one of the largest financial institutions in India is hosted there, adhering to strict SLAs that require prompt responses.

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.
