Nordian, a European private equity firm focused on technology-driven growth, has announced a strategic investment in Deciso, the Dutch company behind the OPNsense open source firewall and router platform. The investment is intended to accelerate the development of OPNsense while expanding Deciso's European-designed cybersecurity hardware portfolio and supporting greater digital sovereignty across Europe.
The partnership provides Deciso with additional resources to strengthen the long-term development of OPNsense, one of the world's widely adopted open source firewall and routing platforms. The investment will support continued feature enhancements, security hardening, and community-led innovation while ensuring the platform remains transparent, secure, and sustainable.
By expanding engineering resources, Deciso aims to accelerate innovation across its cybersecurity software ecosystem.
A key objective of the investment is to scale Deciso's European-designed hardware portfolio. The company plans to accelerate the design, manufacturing, and distribution of purpose-built routers, firewalls, and security appliances that run OPNsense natively.
The investment will also strengthen manufacturing capacity, production processes, logistics, and supply chain efficiency, enabling Deciso to serve a growing global customer base with scalable cybersecurity infrastructure.
The partnership aligns with broader efforts to strengthen European digital independence by reducing reliance on non-European providers of critical cybersecurity infrastructure.
Through continued investment in locally designed and manufactured security solutions, Deciso and Nordian aim to promote transparency, open source development, and resilient cybersecurity technologies that support privacy and long-term infrastructure independence.
Jos Schellevis, CEO, Deciso "Nordian's investment will catalyze Deciso's growth. OPNsense has proven itself to be a secure, trusted platform. Expanding our European designed hardware portfolio lets us provide adaptable, resilient solutions that uphold our shared values of openness and independence."
