Onyxia Cyber Launches Nexa: The AI Agent Redefining Preemptive Cyber Resilience for CISOs and Security Teams

Onyxia Cyber, the leader in Preemptive Cyber Resilience, announced the launch of Nexa, a groundbreaking AI Security Agent designed to transform how security teams interact with their data. Nexa moves beyond generic AI by analyzing security data and asset inventories within the specific context of an organization’s unique environment, providing trustworthy, actionable insights for optimal decision-making, and recommended actions for preemptive exposure mitigation.

In a world of data fatigue, Nexa is the CISO’s right hand and a trusted source for the entire security team, delivering the data-driven answers and context-aware recommendations they need to make critical decisions. By integrating directly into an organization’s cybersecurity ecosystem, Nexa eliminates manual correlation and provides instant clarity across the security environment.

Sivan Tehila, CEO and Founder of Onyxia Cyber, commented on the significance of the launch:

“With the launch of Nexa, we turn asset inventory into action. Nexa allows CISOs and every member of the security team to ask critical questions and receive contextualized, prioritized recommendations tailored to their specific environment. By normalizing complex data and making it actionable, we are enabling teams to uncover gaps, analyze risk implications, and initiate preemptive mitigation workflows.”

Nexa delivers immediate insights into an organization’s security posture, answering questions that address aspects across all security domains, including:

• User Audits: “How many active users are registered in our systems?”
• Environmental Changes: “How many new Windows devices were added since January 1?”
• Vulnerability Impact: “How many hosts are affected by the new CVE-2026-XXXX vulnerability?”

Why Nexa is a Game Changer:

• Cross-Domain Intelligence: Nexa collects and normalizes data from all security domains, providing a unified view of an organization’s entire environment.
• Seamless Collaboration: Nexa breaks down silos by giving CISOs and every member of the security team a single, reliable source of truth.
• Decisive Action: Move from insight to impact. Nexa provides recommended actions and strategic guidance to preemptively strengthen cyber resilience.

Nexa is now available to the market, providing a seamless way to improve security posture through the power of context-aware and agentic artificial intelligence.

Harshal Mehta, CISO & Onyxia CISO Advisor, shared: “Onyxia’s Preemptive Cyber Resilience Platform is central to a CISO’s automation strategy, particularly as security teams increasingly integrate Generative and Agentic AI into our ecosystems. Instead of manually pulling data, we can now use an AI agent like Nexa to ask complex questions – like ‘How has patch management performed over the last few weeks?’ – and receive instant, intuitive dashboards. It’s a shift from running reports to having a real-time dialogue.”
