Horizon3 is the AI-Native Proactive Security Company behind NodeZero®, the World’s Best AI Hacker™. Founded by experienced cyber operators, security practitioners and startup engineers, Horizon3 helps organisations across financial services move beyond checkbox compliance, alert fatigue and point-in-time assessments.

NodeZero autonomously and safely tests an organisation’s external, internal and cloud environments from an attacker’s perspective. It identifies and prioritises exploitable attack paths, not just theoretical vulnerabilities, so teams can focus on weaknesses most likely to affect services, data and operational resilience. Once issues are remediated, NodeZero instantly verifies that fixes work, creating a continuous hack, fix, verify cycle at machine speed.

For financial institutions, this provides actionable evidence to support risk-based decision-making, strengthen control assurance and help demonstrate that security measures are effective in practice. By reducing reliance on costly, time-consuming manual testing, Horizon3 enables teams to continuously understand, communicate and reduce cyber risk, with human expertise applied where it matters most.
