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

"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."
"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."
"We use this tool to quickly assign privileges to different users as soon as they come in."
"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."
"Without the product, extracting this information may take us as much as several days; instead, we can get it in real time."
"We also use IBM Guardium to support security initiatives and compliance policies. For example, our audit area can verify if someone has access to information that they shouldn't have, for their regular job functions."
"The most valuable feature is the GUI, the interface. It also interfaces well with REST API, if you want to automate some of the commands."
"The solution has definitely saved us time, because if you want to monitor this kind of vast environment of different products, it's going to take a lot of time. Let's say one database server has 100 database instances running on it; I don't need to install 100 data instances, I just need to install on the one database server and that will cover all of my instances on that particular database."
"The most valuable feature of the solution for the customers is the monitoring and full log of the database activity of privileged users."
"The valuable features enable us to track all activities on the database, it has helped improve the visibility for our data usage, and it is very useful."
"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."
"It supports our audit compliance."
"Ease of deployment is a valuable feature."
 

Cons

"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."
"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. 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 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."
"Lower pricing would always be good but apparently we're getting our money's worth or we wouldn't be using it."
"The scalability is not that easy to use because, you need a lot of knowledge about it, on data security; basically you need to know where your sensitive data is."
"An improvement would be to make the pricing relative in terms of regions."
"They could enable the out-of-the-box feature to track application user activity."
"The initial setup was complex."
"Sometimes the connectors to the databases need to be manually updated and we have to configure them again, which is something that should be improved."
"We did find some difficulty in deploying IBM Guardium Data Protection here in Pakistan because of the lack of resources."
"The most important requirements for us are integration with new database solutions and the ability to manage things like Jailbreak or something like that. Its reduction feature can also be improved. It has a functionality called reduction, which is like masking data, but it is just a replacement of characters. Sometimes the customer needs more than this. It would be good if it was more advanced or complete. We also have a problem with this solution because the IBM aggregator isn't working very well. IBM has created big data intelligence for Guardium, and occasionally, customers need three or four months of data, but they can't run it from the collectors. It can have a better dashboard and more pre-defined use cases for those customers who don't have any idea about data protection or don't have expert personnel in this area. For example, they can include five use cases for banks and five use cases for retail."
 

Pricing and Cost Advice

Information not available
"The price of Guardium is higher than the main competitor, Imperva. In addition, it's complex as the calculation of the licensing is done by Processor Value Unit (PVU). However, before purchasing a DAP solution, it is important to analyze specific points to evaluate the cost-benefit of each tool. For example: Does the environment to be monitored have mainframes? If so, it's a point for Guardium. If not, a point for Imperva. Note: IBM is looking into a new licensing policy and reducing the price of Guardium."
"Guardium's pricing is quite high, but it gives good value for money for all sizes of enterprises, especially for partners."
"The price is good for the quality of the solution."
"Reasonable cost but could be lower."
"Guardium has not saved us time or money."
"Licensing fees are paid on a yearly basis."
"IBM Guardium Data Protection charges you based on the number of users, e.g. based on the number of licenses, and it's either on a per-license or a per-data basis."
"Guardium won mostly because of our scope and scale. It was able to perform at the scale that we wanted to use it. ​"
