Nucleon Security

Cyberattacks are projected to cost businesses $10.5 trillion globally by 2025, while the cybersecurity talent gap remains severe, with nearly 4 million professionals missing worldwide. Nucleon Security addresses this challenge with a proactive and automated Zero Trust platform, already protecting over 100 clients across three continents.

The company’s solutions cover the full defense cycle: endpoint protection with its Zero Trust EDR that blocks suspicious activity by default; 24/7 sovereign MDR ensuring local and independent monitoring of critical data; advanced malware analysis through Malprob AI to identify unknown threats before they spread; and ScorX, which prioritizes alerts to highlight the most critical risks.

What sets Nucleon apart is its use of agentic AI, designed to act as an autonomous co-pilot for cybersecurity teams—able to analyze, decide, act, and continuously learn. This adaptive approach enhances prevention, detection, and remediation for organizations of all sizes.

With its €3 million late seed round in 2025, Nucleon Security is accelerating the industrialization of its AI technologies and expanding its presence in Europe and Africa.
