We believe cyber risk management has evolved from an IT problem into a business problem. Because of this shift, security executives must adapt how they communicate risk to the board. But since risk is hard to frame in the context of a business initiative, security executives need help putting risk into business terms that the board can use to make informed, strategic decisions to drive growth. Additionally, security teams are often seen as the team that says “no”, shutting down projects and initiatives due to risk, which limits growth and results in missed opportunities. At RiskOptics, we aim to make risk management more strategic, pulling it up from tactical “check-the-box” work to something more valuable to both the company and the security team. There’s an opportunity for security executives to go beyond just protecting their company and secure their role as a more valuable, strategic member of the team. We can help by giving them the business context they need to report risk to their board in a way that is easy to understand and act upon.
