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

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

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

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

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

"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."

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

"Know that this tool is a great tool, a good tool to use, because you can quickly automate, quickly provision, and deprovision new users, which is essential when you are bringing new people onboard."

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

More ACF2 pros

"IBM Guardium Data Protection has better integration options than most of the leading competitors on the market, and the price is always better."

"IBM Guardium Data Protection is very good at keeping your database secure."

"The most valuable feature I have found is the performance of client monitoring. The other competitors are unable to do this."

"It has been very difficult to analyze all the network traffic with something else. Guardium provides that feature, it's heuristic. So we have rule-based algorithms in place to take care of that."

"I would definitely recommend it, as it's easy to use and it can save a lot of headaches by just implementing it and being able to answer at the time of audit."

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

"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."

"Database logging and audit functions are the most valuable features."

Cons

"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."

"Initial setup could be complex if you rely on contractors to help with implementation."

"Reporting can sometimes include 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."

"Setup can be complex. The documentation is in so many different locations, and a lot of times we have to leverage support and higher level resources to figure out the right steps to take."

"It was extremely complex. Without IBM support it would take years for you to setup infrastructure."

"The solution could be improved for NoSQL databases."

"It will not go as fast as you want."

"While Guardium is great at structured monitoring (DAM), the product is lacking features on the file activity side (FAM)."

"Personally, I would like to see IBM Guardium have other encryption algorithms employed, such as DES/3DES or TripleDES, Twofish, Blowfish, or IDEA."

"The one thing that I would like to see improved, but I don't think it's going to be in the next release, is its reporting capabilities. I think that's been offloaded to another third-party product that I think IBM actually endorses for that."

"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."

Pricing and Cost Advice

Information not available

"Licensing fees are paid on a yearly basis."

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

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

"Guardium has not saved us time or money."

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

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

"The price of the solution could be better."

"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."
