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.

Quotes from Members

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

Pros

"There are a number of features that are valuable such as the account takeover and various antivirus features."
"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."
"The bot management features are very effective, as they help filter unwanted traffic using keywords."
"Imperva Web Application Firewall is stable."
"It has threat intelligence and we are using Incapsula. With threat intelligence, we can separate HTTP and HTTPS traffic. We can use Incapsula to send all the threat intelligence to the WAF."
"Protection is the best solution since it has profile functionality."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"The solution can be configured in just a couple of minutes."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"Imperva should have more points of presence in Africa."
"I don't really use it and therefore can't speak to areas of improvement."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"I would like to improve the tool's turnaround time in terms of support."
"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."
"The product could use a broader scope in the area of policies."
"A limited tool if you're looking to customize."
"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."
 

Pricing and Cost Advice

"The cost is on par with other solutions such as Cloudflare and Akamai."
"It is not expensive compared to the other similar solutions in this category."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"Everybody complains about the price of this solution."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"Varies depending on the needs of the customer."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
