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.

Chief Information Security Officer at a computer software company with 51-200 employees

It gives us a risk report that helps us refine our process management by highlighting where we might be exposed

Flow's distinctive capability to analyze both data at rest and data in motion grants us the ability not only to get full visibility and classification of the data within our managed databases but also to visualize the data flows both within and beyond our environment. This enables us to achieve a comprehensive understanding of all our sensitive data, even as it traverses through applications, shadow databases, and external services such as third-party entities and SaaS applications. What we aspire to achieve with Flow is extended visibility into the external services themselves, which will allow us to see the data they contain.

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."

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

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

"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."

"Before implementing Flow Security, we had no mechanism to alert us when third-party contractors were accessing sensitive data or moving it to locations with lower security. Now we know precisely where the data is stored and can assess the risk when someone wants to develop something. Flow Security lowers our risk of a data breach."

Cons

"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."

"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."

"It provides a good overview of our infrastructure, but I need more end-to-end visibility, and SaaS is one of the gaps."

Broadcom

Flow is a data security platform that combines Data Security Posture Management (DSPM) together with real-time detection and response to data security violations. Flow is not just your cloud security tool with a data scanning utility. It is the only platform that analyzes both data at rest and data in motion. By also following and analyzing all data flows in runtime, the platform enables security teams to regain control over all their data, including shadow data stores and applications across all cloud, on-prem, and SaaS environments.

Flow’s deep analysis of the organization’s data journey from origin to destination allows security teams to automatically catalog all their sensitive data (e.g. PII, PHI, PCI); visualize data flows; detect and remediate data risks; and effectively respond in real-time to data violations by providing the full context: who, what, when, where and why.
