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.

Centralized monitoring has improved audit readiness and streamlines investigations of data access
IBM Security Guardium Data Protection is a strong platform, but there are a few areas where I think it could be improved. One area is alert tuning and prioritization. Large environments can generate a significant number of alerts, and while the platform provides good visibility, reducing noise and automatically highlighting the highest-risk events would help security teams work more efficiently. Another area is ease of administration. As environments become more complex with cloud, hybrid, and on-premises databases, managing policies and configurations can require significant effort. Simplifying some of those workflows could reduce the operational overhead for administration. I would also like to see deeper automation and more advanced analytic capabilities. The security industry as a whole is moving toward faster threat detection and automated response, and having more built-in intelligence to identify unusual behavior with less manual tuning would be valuable. A couple of additional areas come to mind regarding needed improvements for IBM Security Guardium Data Protection. Integration is one of them. IBM Security Guardium Data Protection integrates with a variety of security tools, but as organizations adopt more cloud-native platforms and multicloud environments, smoother integration and simpler deployment processes would be beneficial. Many security teams are managing dozens of tools today, so reducing integration complexity can save a lot of operational effort. From a usability perspective, some administration and reporting tasks could be more intuitive, especially for new users. The platform is feature-rich, which is a strength, but it can also create a learning curve. Regarding support, my experience has generally been positive, but complex issues can sometimes require coordination across multiple teams before they are fully resolved. One feature I appreciate about IBM Security Guardium Data Protection is the detailed audit trail that IBM Security Guardium Data Protection maintains. When investigating an issue, having a historical record of database activity can save a lot of time and provide the context needed to understand what happened. That is especially useful for compliance and forensic investigations. As for a wish-list item, I would like to see even more intelligent alert correlation and risk prioritization. A challenge across the security industry is that teams often deal with a large number of alerts from different tools, and determining which ones require immediate attention can still be time-consuming. Although IBM Security Guardium Data Protection already provides strong monitoring capabilities, more automated context and prioritization could help security teams focus on the highest-risk events faster.

Quotes from Members

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

Pros

"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."
"Logging and monitoring are most valuable. It is for the mainframe environment, and it is at the forefront for security and resilience."
"Excellent real-time reporting that saves time and resources."
"The most valuable feature is strict and reliable access control to CICS Resources."
"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."
"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."
"I love their support. The support is great. They are number one."
"It does not require our involvement to run it. It runs in the background and the people that do the reporting do so. The reports go to the directors who are in charge of the various data areas. It's pretty clean. Clearly there is some setup, but after you get it set up it just goes."
"The monitoring and analytics capabilities make it a very good product, although we have had intermittent problems with our database connectors so it is not perfect."
"Ease of deployment is a valuable feature."
"The features I like are the robust policies, which allow us to create customized monitoring based on specific activities."
"For security and compliance it is very, very good."
"Audit Process Builder – Workflow generator to enhance audit tasks and compliance workflows."
"The tech support is very knowledgeable."
"It provides us regulatory compliance proof and evidence for audit."
 

Cons

"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.​"
"Reporting can sometimes include false positives."
"Initial setup could be complex if you rely on contractors to help with implementation."
"They can work on its ability to work in a distributed environment."
"The user access review could also be improved. It produces a lot of false positives."
"It needs longer rules. The max rule is 32K."
"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."
"I would like to see a lot of additional reporting and analytics features. They have basic outlier detection, but I would love to see that go further, and model it after analytics tools like Splunk."
"Flexibility could be improved."
"Guardium has limitations so most companies using advanced technologies have stopped using this tool because it doesn't have the capability to identify the PII data in flat files."
"It would be helpful, and convenient to improve the Chat support."
"We have had some issues with patches breaking things unexpectedly in our environments."
"The technical support is very poor."
"We also have a problem with this solution because the IBM aggregator isn't working very well."
"The manuals should be clearer. There needs to be an online course or tutorial for faster management training."
