Comprehensive Approach...

Good risk assessment, upon which actionable decisions can be make, requires the intelligent correlation of substantial operating information with real world impediments. To be comprehensive and exhaustive, hundreds or thousands of asset-threat combinations must be valued, evaluated, and prioritized.

Actionable Insights...

PARRE supports your team in this process, intelligently dealing with this minutiae so that the team can focus on the most important details and actionable insights. We share a written report with you, but we also leave all of the data in an easy-to-use software framework that can be updated and examined through “what if” drills at any time.
