Executive SummaryUpdated on Apr 6, 2025

IBM Security Guardium Data Protection and ACF2 are competitors in data security. IBM Security Guardium Data Protection has a slight advantage due to its advanced analytical tools and streamlined deployment.

Features: IBM Security Guardium Data Protection offers robust data encryption, real-time monitoring, and automated compliance capabilities. It also provides comprehensive security through database activity monitoring and firewall features, making it adaptable to various environments. ACF2 focuses on strong access control, efficient multi-factor authentication, and seamless mainframe integration, appealing to those prioritizing system integration.

Room for Improvement: For IBM Security Guardium Data Protection, areas of improvement include enhancing user interface intuitiveness, expanding cloud compatibility, and reducing complexity in advanced feature deployment. ACF2 could benefit from improving the user experience for non-mainframe experts, expanding feature richness beyond integration, and enhancing its analytical tools to compete directly with IBM's offerings.

Ease of Deployment and Customer Service: Both products offer effective deployment models, but IBM Security Guardium Data Protection is notably more streamlined, reducing implementation time. IBM's customer support is perceived as more accessible and responsive, whereas ACF2 may require specialized mainframe knowledge for support.

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.

Ensures data security and compliance with reliable alerts and protections

The manuals should be clearer. There needs to be an online course or tutorial for faster management training. The maintenance was slightly complicated. I had to read the manuals carefully and even failed the Guardium certification exam due to insufficient information or time. Improving the tool learning process would be beneficial.

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."

"We use this tool to quickly assign privileges to different users as soon as they come in."

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

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

"The NOACCESS by default is another very good feature. Also, access rules are straightforward, and easy to understand."

"I think IMB's technical support is good."

"Guardium is easily integrated with other IBM solutions, a significant advantage and a key reason we chose Guardium. Both platforms share the IBM infrastructure, enhancing compatibility and integration. Additionally, Guardium offers a vulnerability analyzer, which is another compelling feature of the platform."

"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."

"Setting up Guardium was easy and straightforward."

"It's made database monitoring more visible to the business, creating more conversations about how we should do it better."

"Efficiency is key and IBM Guardium provides information in a heartbeat, but protects the data with military grade encryption."

"The front-end works very well."

"The most valuable feature is the visualization of data and the ability to monitor our databases."

Cons

"Reporting can sometimes include false positives."

"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."

"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."

"I would like to see IBM Guardium have other encryption algorithms employed."

"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."

"Overall testing and quality need improvement. It is fairly buggy at times, so it feels like it could use additional staff on the product, testing and trying it out."

"Right now we're having some issues where it's using a high CPU, we don't know why. So, better testing before the product is ready would help."

"The installation should be a bit easier."

"There could be a feature to integrate and protect multiple databases. The local support services need improvements as well."

"Personally, I would not recommend this product."

"We are currently facing a challenge because it does not offer data encryption by default, only data masking."

Pricing and Cost Advice

Information not available

"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."

"Reasonable cost but could be lower."

"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."

"It's an expensive solution"

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

"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."

"The tool is not cheap, but it is not expensive."

"The price of the solution could be better."
