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

"Logging and monitoring are most valuable. It is for the mainframe environment, and it is at the forefront for security and resilience."
"I am deeply impressed with the quality and depth and breadth of security and functionality in CA’s ACF2 and Top Secret products."
"Excellent real-time reporting that saves time and resources."
"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."
"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."
"The most valuable feature is strict and reliable access control to CICS Resources."
"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."
"For security and compliance it is very, very good."
"We acquired Guardium to encrypt certain databases to meet a customer requirement and it has been performing to spec."
"The tool helps detect invalid login attempts within a specific time frame."
"What I like about IBM Guardium Data Protection is that some of its features were deployed by collectors during the installation phase. The solution has collector and aggregator features, license installation, and even server patches that you won't find in other security providers. I like the collector-aggregator capabilities of IBM Guardium Data Protection where you install each component on separate servers, then on the aggregator, you collect all the logs on a central server or central console."
"The most valuable feature is using the capture operation mode “S-TAP/K-TAP agent”, because all activities in the database are captured, including direct access to the database server by privileged users, which is useful because, even if the database server logs were deleted, the Guardium Collector has already stored such data to enable traceability of access."
"It's one of the first to encrypt DB2 databases."
"It provides a comprehensive security for databases, both on-prem and on the cloud. Among the advanced features we use automatic backups, DR."
 

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."
"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."
"It needs longer rules. The max rule is 32K."
"The analysis part of this product could be improved. It's a very comprehensive product, so the features it has complement customer requirements. But I would like to see more emphasis on analytics, and it would be great if they added machine learning. They already have analysis insights, but a comprehensive analytical feature that's already incorporated into the solution would be very helpful."
"Setup cost is a little high as compare to other products available in the market but the service provided by vendor is great and there are many additional functionalities as compare to other tools."
"More automation, user guides, and tips would make this solution better."
"The installation is not straightforward at all. In fact, it is very, very complicated."
"There was a slight performance tax on the system and load balancing could be better."
"We are currently facing a challenge because it does not offer data encryption by default, only data masking."
"We deal with updates manually on Sundays and sometimes face bugs with the newer versions."
"The maintenance and support aspects of the product need improvement."
 

Pricing and Cost Advice

Information not available
"IBM solutions have fair price strategy, and operates on a yearly basis. If it's a SaaS solution, then you can opt for yearly basis."
"My company purchased IBM Guardium Data Protection in a package, so I'm unable to give its exact licensing cost, but for the package of three IBM solutions, it wasn't very expensive. I'd rate the pricing for all three solutions three out of five. When my team deployed IBM Guardium Data Protection, all features were included."
"It is a very costly product."
"Guardium's pricing is quite high, but it gives good value for money for all sizes of enterprises, especially for partners."
"Licensing fees are paid on a yearly basis."
"I would suggest to review the type of data, need for security, and if the organizational structure needs the options IBM Guardium provides."
"One of the deployments that I know of had three databases, and the yearly fees are approximately $50,000 USD."
"The biggest challenge is the cost associated with the product, and the cost of maintaining. Everything is not translated directly to the benefits we see. There are benefits, yes, but if I were writing the check, would I buy Guardium? No."
