Mitesh D Patel

Senior Technical Consultant- Cyber Security at Ivalue Infosolution

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.

Imperva Cloud WAF would be the most powerful option. It uses cloud-based signatures, which are constantly updated. This is different from the on-premises version, where the signature updates might be less frequent. Imperva has basic reporting templates. We can use those, and we can also create custom reports. However, customization is limited to labels and structure – we can't change the actual content of the reports. For that, we need to use Imperva Compass. Overall, I would rate the user experience an eight out of ten, with ten being good experience.

Support is one thing I wish Imperva could improve. They follow the phone model and keep rotating you from one customer service person to another. The layer one support isn't very clear about the workings of the product. My feedback is primarily about Imperva Cloud, not on-premise. On-premise is a whole new story. Support is the issue for Imperva Cloud. It's also a bit pricey. It's a premium service and very expensive. The licensing model is not very straightforward. Every feature is priced separately, and to enjoy maximum protection, you'll have to spend a lot of money. The licensing model is a bit complex, and each feature is very pricey. For example, API security and web application protection are two separate license packages.
