Offers contextual prioritization and risk-based remediation of vulnerability
An improvement would be some sort of an integration with any GRC suite. There are a lot of GRC suites available, like Archer, MetricStream, Rsam, Protiviti, for example. So how would a solution like this work if my company has already invested thousands or maybe millions in a GRC solution? Do I still need it and how does it fit into an existing SAP environment? There could be interoperability, having more data sources, integrating Splunk, Qualys, FireEye, Rapid7, Carbon Black. I'm sure all that can be done to an extent, with a little more insight and a little more accuracy on the industry numbers and trends. I'd like the solution to offer any sort of assistance in any way with the remediation part, not just identification of vulnerability risk, and that is second.

Health Care Specialist at a healthcare company with 11-50 employees
Improved radiation safety and compliance has supported patient care but daily workflows still need refinement
I think it can be improved by making it more practical, integrated, and easier for teams to apply in real-world workflow from a healthcare perspective. The main improvements I can see right now are better user training with real-case scenarios rather than only theory, and clear and simple protocols for day-to-day operations. Strong integration between safety compliance and documentation systems would help significantly in practice for the healthcare field, which is a niche field. The biggest gain would come from making security processes easier to follow consistently, especially in busy environments where teams need to be aware of clarity and really need to rely on the documentation they are using.I chose a rating of seven because it offers strong value in safety, risk reduction, and compliance, especially in healthcare. However, there is still room for improvement in usability and day-to-day integration. Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow.

Quotes from Members

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

Pros

"The risk context of any vulnerability is a valuable feature."
"The risk context of any vulnerability is a valuable feature; that is what it is used for and then data from different sources can be fed into it, and they have good dashboards, risk meters, and virtualization."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
 

Cons

"An improvement would be some sort of an integration with any GRC suite."

Pricing and Cost Advice

"I think the pricing is based on the number of endpoints, so it's more subscription-based."
