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.

Has provided exceptional performance for handling high web traffic
In my opinion, Windows Azure CDN is one of the best CDNs. We tried to replace it and made a business case to check other options such as Cloudflare, and we are using Cloudflare and tried Akamai, wanting to explore alternatives from OCI. One of the best features of Windows Azure CDN is that it has integrated WAF; it is not only CDN alone and it is a very smart and capable WAF. Windows Azure CDN is easily integrated with Azure services such as Azure Storage and Azure Web Apps, and sometimes we are using just Azure Front Door while the back end and database will be on OCI. The impact of Windows Azure CDN's dynamic content acceleration on our application performance is very significant. For one of our clients, we could not use anything other than Azure Front Door.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is very good at intercepting traffic before it gets to our data centers."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"We have peace of mind that nobody will use malware on us or try to hack our website."
"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping."
"It is a stable solution."
"We use the product for faster content delivery with low latency."
"The UI is very intuitive."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"I enjoy engaging in discussions with colleagues possessing unique expertise. I leverage the three platforms—Azure, Google, and AWS extensively. This allows me to offer diverse solutions to customers, commonly referred to as a multi-cloud approach."
"One of the most valuable aspects is the capability to store extensive datasets and objects in the cloud, enabling their download through shared access signatures."
"I like that CDN offers a routing feature."
"One of the tool's best features is its ability to handle edge cases. For instance, we encountered a situation where we needed to remove certain files from public access. The solution offered a purge feature that allowed us to remove these files. This feature ensured that the files were deleted from all edge servers. Subsequently, we were able to upload new versions of the files."
 

Cons

"There’s nothing that’s missing in terms of features."
"Some maintenance must be performed by our IT team."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"Imperva DDoS does not provide version control."
"Certificate management could be improved."
"If they can bring in generative AI features, that would be useful."
"The tool's UI is complicated. It would be best to have a more accessible UI dashboard to make the job easier."
"One potential improvement for Imperva is enhancing its alert system."
"I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"The solution’s pricing could be improved."
"We have experienced issues with switch connectivity."
"They should include configuration for cache rules."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"It is not a weakness of Windows Azure CDN; rather, it is the fact that it is outside Saudi Arabia, leading to some regulation issues."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
 

Pricing and Cost Advice

"There are a couple of different licensing models."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"We are satisfied with the pricing."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
"The tool's pricing is cheap."
"The pricing of the solution depends on usage and varies based on the company's needs. If you want additional features like advanced logging, it will be pricier. However, it could be cheaper if you don't need those features. It all depends on the resources and requirements."
"The pricing is extremely high, almost 9 out of 10."
"It comes at a relatively affordable cost."
"The solution's price is above the medium range."
"The solution's price depends on how much traffic you have. So, it was okay for us. Payments are to be made on a monthly basis since one has to pay for what they used."
"I rate the price of Windows Azure CDN a six on a scale of one to ten, where one is cheap, and ten is high."
