Onyxia Cyber

Onyxia Cyber is a cybersecurity management company that offers a Preemptive Cyber Defense & Planning Platform designed for CISOs and security leaders. The platform is focused on helping organizations move from reactive to proactive and predictive cybersecurity management. The core offering is a Cybersecurity Performance Management (CPM) platform that provides Cybersecurity Performance Indicators (CPIs) to help security leaders measure, communicate, and optimize their security programs. Key platform features include a Security Stack Map, which visualizes how an organization's existing security tools provide coverage across devices, applications, networks, users, and data, and a NIST CSF 2.0-aligned dashboard that allows security leaders to assess their program's adherence to the framework. The platform targets CISOs and senior security leadership who need to quantify the business impact of their security programs, manage compliance with industry regulations, and optimize security investments. It addresses gaps left by legacy tools such as SIEMs, which are not designed for executive-level governance needs. Onyxia Cyber supports alignment with major frameworks, including the NIST Cybersecurity Framework 2.0 and CISA Cybersecurity Performance Goals (CPGs). The company is SOC 2 compliant, reflecting its commitment to data protection standards for its clients and partners. The company was founded by Sivan Tehila, a former Israeli Defense Forces intelligence and cybersecurity officer, alongside CTO Eugene Brodsky, both previously of Perimeter 81. Onyxia Cyber is headquartered and operates as a software company serving enterprise-level organizations.
