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.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"The solution can scale."
"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
"The solution's most valuable aspect is that it is easy to configure."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"The solution has been quite stable. I have not seen any bugs at all."
"Imperva monitors all traffic, even customer access, to the web application. Then, Imperva uses features like signatures to identify attacks like cross-site scripting or SQL injection."
"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."
 

Cons

"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."
"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."
"I think that better bot protection is needed in this solution."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"It's quite expensive."
"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."
 

Pricing and Cost Advice

"The cost is on par with other solutions such as Cloudflare and Akamai."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"The license is on a yearly basis."
"There are a couple of different licensing models."
"Pricing could be more competitive."
"The price is high compared to other solutions like FortiWeb."
"It is a very affordable solution."
