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.

Pricing and ROI: IBM Security Guardium Data Protection has a higher initial setup cost but delivers significant long-term ROI through its comprehensive protection features. ACF2 presents competitive pricing but achieves a slightly lower ROI due to its focus on integration over feature richness. IBM offers better financial value concerning data protection expenditure.

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

"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."

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

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

"Security policy enforcement of policy-based encryption and centralized encryption key management allows us to maintain data in a secure environment."

"It's one of the first to encrypt DB2 databases."

"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."

"It provides us regulatory compliance proof and evidence for audit."

"I think it scales pretty well. It can run on most of the database platforms currently out there. That is something we really like as a feature, because we try to hit everything in our environment to make sure we're meeting those regulations."

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

"The front-end works very well."

"Gathering the data works very well. "

Cons

"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."

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

"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."

"They could enable the out-of-the-box feature to track application user activity."

"I would like to be able to upgrade appliances within major versions without needing to rebuild the appliance."

"Guardium Data Protection is far better in terms of external integration. But in terms of firewall features, like when you're blocking activities, it's as if Oracle AVDF simply has superior features. This is just from third-party observations, but the users of Oracle AVDF are saying that when it comes to the firewall and protection functionality, they're much more inclined to AVDF."

"I'd like to them make sure that the data sources can be more easily managed, because some of them are tied to multiple things. You try to remove one and you have to go to all the different spots to remove the associations before you can get rid of it."

"More automation, user guides, and tips would make this solution better."

"It was difficult implementing it, configuring it, getting it up and running and in production. However, since then, I believe it has stabilized."

"Guardium's storage capabilities could use some improvement. I'd also like to have some better integration using digital technology or a connector."

"Can't be used for a NoSQL database, which is limiting."

Pricing and Cost Advice

Information not available

"It is a very costly product."

"We haven't talked much about pricing and licencing. But it is not cheap for sure"

"The product's pricing is reasonable and affordable. It is in the moderate range."

"Guardium is most suitable for large scale enterprises because the pricing model is better if you are implementing a large number of databases."

"On a scale from one to ten, where one is low price, and ten is very high price, I rate the solution's pricing a nine out of ten."

"The price is good for the quality of the solution."

"Reasonable cost but could be lower."

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