Mitesh D Patel

Senior Technical Consultant- Cyber Security at Ivalue Infosolution

Effectively defends against threats like cross-site scripting (XSS), SQL injection, and others

It does bring value. For example, consider a BFSI customer. Their application is critical and represents their brand. Without a WAF, an attack could take their application down, harming their reputation. It leads to hampering the customer's workflow. With an Imperva WAF, they protect against attacks like DDoS or SQL injection, ensuring their application remains available and customers are happy. That's the main benefit for both the customer and the organization. The impact depends on the customer's use case. If their business primarily operates online, a CDN is beneficial for traffic optimization. Moreover, the integration options depend on the specific use case of our customers. Generally, integration capabilities are good with SIEM (Security Information and Event Management) parts.

Helps us to monitor attacks to our sites and prevents a lot of them

Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"The tool's profiling feature maps all the web application directories and related components on the profile directory. It has improved the security of my client's website applications."

"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."

"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."

"There are a number of features that are valuable such as the account takeover and various antivirus features."

"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."

"Imperva Web Application Firewall is stable."

"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."

"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."

More Imperva Web Application Firewall pros

"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."

Cons

"The user interface could be better."

"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."

"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."

"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."

"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."

"It is complicated to integrate the solution's on-cloud version with other platforms."

"The support for the on-premises version needs improvement."

"There is nothing specific where the application firewall is falling short."

More Imperva Web Application Firewall cons

"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."

Pricing and Cost Advice

"The price is high compared to other solutions like FortiWeb."

"It's an excellent product, but it can be very costly."

"The price of Imperva Web Application Firewalls is expensive compared to others."

"The tool is expensive."

"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."

"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."

"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."

"Imperva Web Application Firewall's pricing is expensive."

More Imperva Web Application Firewall pricing and cost advice

"Pricing must be cheaper than the competition and the licensing must be good."

Questions from the Community

Which is the best DDoS protection solution for a big ISP for monitoring and mitigating?

My recommendation is Imperva.

See all answers

Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?

For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.

DDoS solutions: Any other solutions to consider aside from Radware DDoS Protection Service and F5 Silverline DDoS Protection?

You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperv...
