Tenable SC can cut manpower costs on manual scans and analysis by more than half within one or two years.

The ROI is almost guaranteed because there is a lot of value in using the product and reporting that to our company. 

It's less a question of ROI and more a question of cost avoidance, meaning avoiding the potential cost from having a vulnerable device that can be breached. Security is a sunk cost in any organization. You never truly know its value until you have an incident.

Having Tenable is a requirement. It is a compliance piece which is part of our business. But it is money well-spent in that it focuses us to work on problems that are prioritized and it allows us to cut down on the manual integration of multiple reports from Microsoft and Linux, etc. It does save us considerably in that we can have less staff assigned to it, versus having a Linux team and a Windows team and a NetApp team, etc.

Running with a much smaller team of two people probably saves 80 percent of manpower. I would assume that the team would be ten people or so if we had to mash together multiple reports and spend time doing that.

Tenable SC helps us save about 20% of the price compared to Nexpose, which involves buying three different licenses.

We have seen ROI with the tool's use. 

We've seen return on investment through visibility, scan stability, ensuring that we're able to assess our environment. Also, ensuring that we are able to have good confidence in the data, and that we're able to do out-of-the-box reporting and various other dashboards that really help us drive our program and help sell our case.

We have seen ROI for this solution. It has reduced our security vulnerabilities. Even during the national audit, one of the findings is that this solution is helping us be more productive. We're able to find these issues before somebody else finds them. We can fix them before they are discovered by others.

We're able to save because we don't have to employ more staff members to help with the scheduling of the scans, running the reports or sending them out to the system owners. That alone is a big ROI. A massive security breach would cost us a lot. This is a preventative measure worth our investment.

Yet to be calculated.
