A reliable, scalable product for security and auditing of our mainframe environment
It is a good product. It has been used for years. As long as it is configured correctly, it is a very stable product. It depends on how an institution or a company configures it. It depends on an institution's risk appetite. You need to make sure it is configured as per the concept of least privilege, and the logging features, detection and control mechanism, and other things like that are enabled. If you configure it to give access to the public, then there could be compromises. You should also have someone who independently checks it to make sure that it is configured keeping security in mind. If it has been configured for a while, when there are enhancements to the product or when you enhance it, you need to make sure that security is also looked at, and it is configured according to an institution's security policies. I would rate it a nine out of 10.

Has provided wide data coverage and supports flexible implementation for growing database environments
Imperva SecureSphere Database Security offers the most comprehensive coverage range of database types, which is a significant advantage. It has very flexible implementation modes and an understandable console. Even someone who is not a database administrator could work with it, understand the security events, and comprehend the data activity monitoring events.Data is the most important asset in any organization and the primary target of hackers. Imperva SecureSphere Database Security provides one of the best solutions to analyze data, maintain GDPR compliance, and help investigate any incidents. It is user-friendly and can start with a small scope. Unlike competitors such as IBM Guardium and Oracle, customers can start with a small scope and scale every year. This advantage allows them to invest less money initially while learning the solution. Year after year, they can add value scope and cover more databases in their organization with high quality. We have been working with Imperva SecureSphere Database Security for about 10 years. I started working with this project about five years ago.

Quotes from Members

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

Pros

"The NOACCESS by default is another very good feature. Also, access rules are straightforward, and easy to understand."
"Logging and monitoring are most valuable. It is for the mainframe environment, and it is at the forefront for security and resilience."
"By providing a high level of access control to the z/OS systems, ACF2 allows us to maintain tight controls on dataset and system access and helps us keep unauthorized users from accessing PHI or PII data."
"Know that this tool is a great tool, a good tool to use, because you can quickly automate, quickly provision, and deprovision new users, which is essential when you are bringing new people onboard."
"We use this tool to quickly assign privileges to different users as soon as they come in."
"It is a good product."
"Without the product, extracting this information may take us as much as several days; instead, we can get it in real time."
"Excellent real-time reporting that saves time and resources."
"The product’s most valuable feature is real-time highlights."
"I like almost everything about the solution, including sensitive data scanning, which is the most important, the data discovery is great as well, and I like the activity monitoring, which was the main reason we purchased the tool."
"It is very effective, and we are using four main features. The first feature is cluster management, which allows me to redirect an agent to another gateway if one goes down."
"The most valuable features include a great level of automation, machine learning for attack validation, and a very flexible and comfortable management console."
"All of Imperva’s features are extremely powerful, while a certain degree of knowledge is required to have a solid understanding of the product."
"The initial setup is very simple."
"Our primary use for this product is as an application firewall."
"Imperva is a product leader in this line, and it is very good."
 

Cons

"Initial setup could be complex if you rely on contractors to help with implementation."
"I would like my team and me to be able to use simple browsers, like Chrome, to be able to access mainframe data and provision users using the browser.​"
"It needs longer rules. The max rule is 32K."
"Reporting can sometimes include false positives."
"The user access review could also be improved. It produces a lot of false positives."
"They can work on its ability to work in a distributed environment."
"They can work on its ability to work in a distributed environment. It's a mainframe product. As many companies move to the cloud, depending on what cloud models they choose, such as a public, hybrid, or private cloud, it should be deployable. I am not sure if it can be deployed on those platforms. It has been there since the '50s or '60s, and it's still scalable. It has survived all these years, and it's scalable to many platforms, but I don't know about the cloud."
"There are delays in responses from technical support, but you do get a response per SLA."
"I'd like to see some sort of solution for storage."
"Imperva must work on more features for z/OS."
"The development mode on the platform needs improvement."
"The firewall features are not very strong and should be improved."
"Some cloud versions are not supported by the agent."
"It can be simplified as it is a little complicated."
"The development mode on the platform needs improvement. For example, the archiving functionalities should be enhanced to allow easy conversion of archived logs into CSV or Excel formats for data analysis."

"The cost of support for this solution is very expensive."
