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

"I love their support. The support is great. They are number one."
"Without the product, extracting this information may take us as much as several days; instead, we can get it in real time."
"The NOACCESS by default is another very good feature. Also, access rules are straightforward, and easy to understand."
"We use this tool to quickly assign privileges to different users as soon as they come in."
"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."
"The most valuable feature is strict and reliable access control to CICS Resources."
"It is a good product."
"The ability to audit across multiple data environments led to a greater understanding of the data traffic and the potential weaknesses in the access controls."
"Good data encryption and data masking features."
"Guardium has save us a lot of time, especially with the things it can automate."
"We use Guardium to support security initiatives and compliance policies such as APCI, SOX, GDPR, pretty much everything."
"Ability to define reports based on SQL query, especially when you have complex report criteria."
"Its ability to find data; once I find data, I can leverage it to perform specific select statements against PII data and do smarter controls rather than monitoring the entire database."
"We appreciate its ease of implementation and the local support available for the product."
"IBM Guardium Data Protection improved our organization by providing visibility into our database functions."
 

Cons

"Initial setup could be complex if you rely on contractors to help with implementation."
"It needs longer rules. The max rule is 32K."
"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.​"
"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."
"Reporting can sometimes include false positives."
"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."
"Sometimes the performance is not good, and also sometimes we have sudden bugs causing difficulties."
"IBM Guardium Data Protection is a mature product. There is a lot of encryption that is not owned by IBM and is done by a third party and is not an integral part of the solution."
"Guardium has not saved us time or money."
"It was extremely complex. Without IBM support it would take years for you to setup infrastructure."
"I am struggling getting through to social."
"The installation should be a bit easier."
"An area for improvement would be the user interface - currently, it takes around two to three months to become comfortable using it."
"Needs easier integration with custom applications."
