Meet Onyxia Cyber

Setting the standard for cybersecurity management.

Our Mission

Along with constantly battling an ever-evolving threat landscape, CISOs today face multiple challenges in quantifying and conveying the business impact of their critical cybersecurity programs. According to Gartner Inc., by 2026, 70% of boards will include one member with cybersecurity expertise, heightening the need for security leaders to demonstrate the impact of their cybersecurity measures at the business level.

Our mission is to empower CISOs with a unified view of their cybersecurity program and deliver actionable insights for high-performing cyberdefense strategies that align with business objectives, enabling them to keep their organizations safe from emerging threats, focus on what matters most, and make smarter and more efficient decisions.
