Featured Reviews

Abdullah Jin - PeerSpot reviewer
Offers bot protection and DDoS Protection and protects public-facing portals
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.
Shashank N - PeerSpot reviewer
Provides good stability, but the agent-based approach could be more convenient
The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF. Additionally, the agent-based approach presents challenges with managing agents across versions and dependencies on specific application platforms like Apache or NGINX, leading to compatibility issues and complexity in integration. This agent-based system proved particularly difficult to manage.

Quotes from Members

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

Pros

"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."
"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."
"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"Data masking is the most valuable feature of this solution."
"Imperva has a complete picture of how the applications are utilizing it. It is handy. DDoS is good. It has an internally managed database. It is very easy to integrate. We have integrated it with SIEM services."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"The solution is cloud-based and offers us good uptime. It has combined web and API security. Therefore, with one license, you access both application security and also API security."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"Support is one thing I wish Imperva could improve."
"Sometimes our web application firewall will slow down."
"The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you."
"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 helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."
"The solution works for particular zones but isn't always the best solution for all zones."
"The tool needs to improve CPU and storage memory."
"Sometimes, support tickets don't get addressed quickly."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"The cost of this solution depends on the platform."
"It is a very affordable solution."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"Imperva Web Application Firewall's pricing is 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."
"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."
"The solution's pricing is an issue."
"There are a couple of different licensing models."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."

Questions from the Community

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 DefensePro 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...
What do you like most about Signal Sciences?
The product's most valuable feature is its ability to set up the rules easily.
What needs improvement with Signal Sciences?
Fastly don't support caching for China users. That's the only feature lacking compared to Akamai.
