Tutus and Sentyron Together at Enforce Tac – Strengthening a Shared European Security Mission

At Enforce Tac 2026 in Nuremberg, CR Group’s subsidiaries Tutus and Sentyron exhibited side by side for the first time. While both companies have long protected sensitive information within their respective domains, this marked an important step: presenting a shared commitment to high-assurance security solutions for Europe’s defence and security community.

Enforce Tac gathers decision-makers and specialists from across defence, law enforcement, and industry. For CR Group, the event reflected something more than product showcases. It demonstrated how the group actively supports its companies in reaching their full potential, both individually and together.

Complementary strengths across classification levels

Tutus and Sentyron operate in adjacent but distinct security domains. Tutus develops Swedish high-assurance solutions for secure communication and information protection, approved for handling classified information up to Restricted / EU and NATO Restricted levels.
Sentyron, based in the Netherlands, delivers certified high-assurance security solutions, including data diodes and advanced cryptographic systems, designed for environments requiring protection at the highest classification levels, including Top Secret.

Together, the companies address a broader spectrum of security needs, from tactical secure mobility and encrypted communications to strictly controlled information flows in highly classified environments.

A long-term owner enabling collaboration


CR’s ambition is to provide stability, strategic direction, and resources that enable our companies to grow stronger in their own rights, while also identifying opportunities where collaboration creates additional value. While our companies operate at different assurance levels, they serve overlapping customer communities across defence and national security.

As geopolitical uncertainty increases across Europe, demand for trusted cybersecurity partners continues to grow. CR Group remains committed to investing in its subsidiaries by expanding capabilities, supporting innovation, and ensuring that each company has the conditions needed to thrive in highly regulated and mission-critical environments.

Building a stronger European cybersecurity group

The conversations in Nuremberg reflected a shared reality across Europe: secure communication and controlled information flow are foundational to defence readiness and national resilience.
Through Tutus and Sentyron, CR Group contributes to that mission across multiple assurance domains. By fostering collaboration while preserving deep technical specialization, CR continues to strengthen its position as a trusted European cybersecurity group.
