NATO formalises cyber partnerships with Microsoft, Palo Alto Networks and ESET

NATO has announced strategic partnerships with Microsoft, Palo Alto Networks and ESET during the International Conference on Cyber Conflict (CyCon) in Tallinn, Estonia. The non-commercial agreements are intended to facilitate information sharing, the exchange of best practices and coordination on cyber incidents of mutual concern.

The partnerships follow a commitment made at the 2023 NATO Summit in Vilnius, where member states agreed to expand structured cooperation with private-sector cyber companies. Speaking at CyCon, NATO Assistant Secretary General for Cyber and Digital Transformation Jean Charles Ellermann-Kingombe said effective cyber defence depends on both technical capabilities and shared norms, particularly as attacks on critical infrastructure become more frequent and cyber threats evolve.

The three companies bring distinct capabilities: Microsoft operates one of the largest threat intelligence networks globally; Palo Alto Networks specialises in enterprise network and cloud security; and ESET is one of the major providers of endpoint protection with significant presence in Central and Eastern Europe.

The 2026 CyCon edition, themed ‘Securing Tomorrow,’ runs 26–29 May and convenes approximately 800 participants — including policymakers, technical experts, academics, and industry representatives — from 48 countries. The conference is organised annually by NATO’s Cooperative Cyber Defence Centre of Excellence, based in Tallinn.

Why does it matter?

Governments increasingly rely on cooperation with private-sector cybersecurity companies to identify threats, protect critical infrastructure and respond to cyber incidents. The partnership reflects NATO’s recognition that much of the expertise, threat intelligence and digital infrastructure relevant to cyber defence is operated by industry.

The agreements also signal a broader effort by the alliance to strengthen cyber resilience and improve coordination as cyber threats become more sophisticated and increasingly target both civilian and military systems.
