IT Examiner at a financial services firm with 10,001+ employees

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.

Jefe De Continuidad Operacional at a insurance company with 501-1,000 employees

Has improved data visibility and streamlined compliance reporting across multiple database platforms

The best feature is how many databases we can protect with one solution because it has compatibility with different databases, including Oracle, SQL, and DB2. The data activity monitoring feature is very good because we can check the PDS and have the information for that. We can schedule the reporting and receive it by email, which provides very important information for different areas of the company. We don't need to have a seat and a case or access to the portal, we just receive the report. The user-friendly interface is very good.

Quotes from Members

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

Pros

"Excellent real-time reporting that saves time and resources."

"I love their support. The support is great. They are number one."

"The most valuable feature is strict and reliable access control to CICS Resources."

"Without the product, extracting this information may take us as much as several days; instead, we can get it in real time."

"It is a good product."

"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."

"Logging and monitoring are most valuable. It is for the mainframe environment, and it is at the forefront for security and resilience."

More ACF2 pros

"Overall, this is a wonderful product."

"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."

"The most valuable features of this product are activity monitoring on the database servers, discovery capabilities, and vulnerability scanning."

"It provides a comprehensive security for databases, both on-prem and on the cloud. Among the advanced features we use automatic backups, DR."

"Database Activity Monitoring fulfills the international standard security requirements, such as PCI DSS, and is very transparent on all of the query access controls of the monitored databases."

"Accelerators is one of the big functions they have out there. It gives you canned reports that you don't have to make yourself, they're out there by being part of the patch. You just have to fill your information in to some of the already built groups, for your environment, and it automates a lot of that. That has definitely helped improve things."

"Compliance Quick Start – Quick, GUI, step-by-step guide to automate compliance and give the customer a quick ROI."

"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."

Cons

"The user access review could also be improved. It produces a lot of false positives."

"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."

"It needs longer rules. The max rule is 32K."

"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."

"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."

More ACF2 cons

"I'd like to see a smoother GUI interface for the CAS agent - CAS does configurations on the database - to interface better with the vulnerability assessments."

"The biggest complaint that I hear from customers and users is that using this solution requires database skills, yet it is a security and monitoring tool."

"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."

"Initial setup is very complex. Once you start interacting with people's databases, they get very hesitant. Then, the amount of social tasks to socialize the solution ensuring people are comfortable with it became a much heavier lift."

"My only negative thing on Guardium would be it is too smart."

"Reporting has always been a weakness, but it has improved across the versions."

"The installation is not straightforward at all. In fact, it is very, very complicated."

"I would like to see streamlining of some of the agent features, some of the patches; make it a little bit more user-friendly on the documentation."

Pricing and Cost Advice

Information not available

"Licensing fees are paid on a yearly basis."

"For IBM Guardium, licensing is very simple and straightforward. There are no issues I can speak of."

"If you are researching this type of solution, work with IBM."

"Guardium won mostly because of our scope and scale. It was able to perform at the scale that we wanted to use it. "

"Guardium's pricing is quite high, but it gives good value for money for all sizes of enterprises, especially for partners."

"It is not an expensive product. We purchase its yearly license."

"One of the deployments that I know of had three databases, and the yearly fees are approximately $50,000 USD."

"The cost depends on the number of databases. You can purchase advanced licenses, but the standard license is calculated based on the number of databases you have to onboard."
