Terma’s Acquisition of Dencrypt: Why Sovereign Cybersecurity Is Becoming a Defense Capability

Europe’s defense build-up is elevating cybersecurity sovereignty to a strategic capability. Terma’s acquisition of Dencrypt illustrates how secure communications, cryptographic control, and technological sovereignty are moving closer to the core of defense strategy. The blog examines the deal in the context of ReArm Europe and its implications for vendors, service providers, and defense users.

Terma’s recent agreement to acquire Danish encryption specialist Dencrypt goes beyond a typical cybersecurity deal. It signals a significant shift in the European defense landscape, where secure communications, control over cryptographic technologies, and technological sovereignty are becoming increasingly important to military capabilities and national security.

The timing is significant, as Europe is entering a period of substantially higher defense investment under the European Commission’s ReArm Europe / Readiness 2030 agenda. This ambitious plan is set to unlock up to €800 billion in additional defense funding, including the €150 billion SAFE loan instrument that supports investment in priority defense capabilities, such as cybersecurity. Moreover, EU policy is increasingly focused on strengthening the European defense industrial base, encouraging joint procurement, and reducing reliance on external suppliers. This creates an encouraging landscape for European defense companies, especially those that can effectively integrate military platforms with locally or regionally controlled digital and cybersecurity capabilities.

By combining Terma’s expertise in defense systems, including command and control, radar, and electronic warfare, with Dencrypt’s end-to-end encryption technology, the acquisition is especially timely. As European armed forces become more interconnected, the need for secure information exchange among soldiers, command structures, drones, and allied forces continues to grow.

The key concern is not simply whether communications are encrypted. Defense organizations also need sufficient control over the technologies, infrastructure, software, and supply chains that underpin operational communications.

What Is Happening?

On August 17, 2026, Terma, a Danish defense technology company, announced it had reached an agreement to acquire Dencrypt, a Danish specialist in encrypted communications. Dencrypt provides end-to-end encryption for voice, video, messaging, and file exchange, backed by secure server infrastructure for authentication, user management, certificate management, and administration.

Its technology is designed for high-security environments and holds NATO and national security accreditations. For Terma, the acquisition adds a dedicated secure communications capability to a portfolio already focused on the military and government sectors.

The intention is to integrate Dencrypt’s technology into Terma’s broader defense portfolio and expand its use in Denmark, allied countries, and selected international markets. The transaction, therefore, gives Terma greater control over a technology layer that is increasingly relevant to connected defense systems.

Why Is This Strategically Important?

Modern military operations depend on rapid and secure information exchange across an increasingly distributed environment. Command centers, deployed forces, intelligence units, sensors, autonomous systems, aircraft, ships, drones, and external partners all generate and consume sensitive information that must remain available and protected.

As these environments become more connected, cybersecurity extends beyond protecting the IT systems supporting military operations. It increasingly determines whether digital military capabilities can be trusted and used under operational conditions. Secure communications are an essential part of this architecture.

For armed forces, sovereignty therefore extends beyond where information is stored. If operational communications depend on cryptographic technologies, key management, software updates, or other components controlled by external entities, defense organizations retain dependencies that may become problematic during geopolitical crises or supply disruptions.

That is why Dencrypt is strategically relevant to Terma. By adding a domestically developed and controlled encryption capability, Terma can offer defense customers greater control over an important part of their communications architecture.

ReArm Europe emphasizes a crucial point: it’s not just about spending more on defense. The initiative links increased investment to the goal of strengthening European industry and reducing reliance on external sources. This approach is further developed in the Defense Readiness Roadmap 2030, which highlights the need for Europe to focus on key areas, including cyber defense, artificial intelligence, and electronic warfare. In this context, secure communications and cryptographic control become vital components of Europe’s broader efforts to improve defense readiness and achieve greater technological independence.

The acquisition also reflects the continuing digitalization of European defense. AI-supported intelligence, unmanned systems, integrated command and control, and increasingly connected weapons and sensor platforms all depend on reliable communications and secure information exchange.

Secure communications are therefore evolving from a specialized cybersecurity capability into part of the underlying architecture of digital defense. Terma’s existing capabilities in command and control, radar, aircraft self-protection, and systems integration make Dencrypt a logical addition to that architecture.

This broader shift toward technological control is also visible in AI and cyber defense, as discussed in PAC’s Expert View on how sovereign AI is shaping cyber warfare.

What Does This Mean for Software Vendors?

The transaction illustrates how the evolving European defense landscape is reshaping the competitive requirements for cybersecurity vendors. Technical capability remains important, but defense customers also consider where technology is developed, who owns the intellectual property, how encryption keys are managed, whether updates remain available during a crisis, which jurisdiction applies, and whether products meet required defense and government standards.

Dencrypt brings cryptographic expertise and security accreditations, while Terma contributes defense integration capabilities and established access to military customers. The combination demonstrates why cybersecurity technologies often gain additional value when integrated into broader defense architectures.

For smaller European cybersecurity companies, this creates both an opportunity and a challenge. Defense markets can generate attractive demand, but they also involve:

• certification requirements,
• long procurement cycles,
• restricted environments, and
• integration with existing military platforms and command systems.

ReArm Europe could reinforce this trend by increasing defense investment and encouraging greater participation from European industry. Cybersecurity companies with unique European intellectual property, models for sovereign deployment, defense-grade certifications, or technologies that help minimize strategic dependencies could be viewed as more attractive partners, suppliers, or even acquisition targets by larger defense firms.

For global cybersecurity vendors, the implications are different. Standard global delivery models may remain acceptable in many enterprise environments, but European defense customers are likely to place greater weight on:

• technological sovereignty,
• operational resilience,
• jurisdiction, and
• supply chain control.

Encryption is one example, but the same questions increasingly apply to identity management, data protection, secure collaboration, AI security, security operations, and other components that become embedded in military systems.

What Does This Mean for Security Services Providers?

Security services providers face a significant but demanding opportunity in the defense sector. Secure communications require architecture, integration, deployment, identity and certificate management, and ongoing operations. Defense environments add requirements around classified information, restricted networks, operational continuity, and interoperability between national and multinational forces.

Cybersecurity for defense cannot, therefore, be reduced to software implementation alone. Systems integrators and security service providers need to connect secure communications with identity systems, command-and-control platforms, networks, endpoint security, cryptographic infrastructure, and operational processes.

The Terma-Dencrypt transaction also illustrates a potential structural change. Larger defense companies may bring strategically important cybersecurity capabilities into their own portfolios rather than relying exclusively on independent technology suppliers.

The push for increased defense spending in Europe, driven by initiatives such as ReArm Europe, could significantly expand the market. However, it could also reshape how contracts are structured. As governments focus more on joint procurement, readiness, building local industrial capacity, and reducing dependencies, service providers will likely need to demonstrate how they fit into a trusted European defense ecosystem. This means they can’t rely solely on general cybersecurity skills; they need to prove their value in a more collaborative and integrated defense landscape.

For service providers, two positions appear particularly relevant.

1. They can become specialized partners for sovereign defense platforms, providing integration, operational support, accreditation, and lifecycle services.
   Alternatively, they can build broader sovereign cybersecurity propositions covering secure communications, identity, encryption, SOC services, cloud, data protection, and resilience.
2. In both cases, generic cybersecurity capabilities will not be enough. Providers need to demonstrate that their technology, personnel, delivery processes, supply chains, and support models can meet the specific sovereignty and security requirements of defense customers.

What Does This Mean for Defense and Other Enterprise Users?

The transaction is particularly relevant for defense ministries, armed forces, intelligence agencies, and related organizations. For them, secure communication is not simply another collaboration service. It supports:

• operational command,
• crisis management,
• intelligence exchange, and
• coordination with allied forces.

The Terma-Dencrypt combination underscores why procurement decisions must look beyond functionality and conventional cybersecurity criteria. Defense organizations should understand:

• who controls cryptographic infrastructure,
• administrative functions,
• certificate and key management,
• software updates,
• support services,
• intellectual property, as well as
• which external dependencies could pose problems during political conflict or supply disruption?

Customer-controlled deployment can therefore provide strategic benefits. Dencrypt supports deployment models in which customers retain substantial operational control. Combined with Terma’s systems-integration capabilities, this can enable secure communications to be more tightly integrated into national defense environments.

These considerations also apply to government and critical infrastructure, although the required degree of sovereignty varies by sector. A commercial organization may accept dependencies that would be inappropriate for a military command environment.

The principle is straightforward: the more operationally critical a digital capability becomes, the more closely organizations should examine the dependencies underpinning its security, availability, and continued operation. Defense sits at the most demanding end of this spectrum.

What Does This Mean for the Cybersecurity Market?

Terma’s acquisition of Dencrypt illustrates the convergence of three markets that have traditionally been relatively separate:

• defense technology,
• cybersecurity, and
• digital sovereignty.

ReArm Europe highlights a crucial backdrop to the ongoing changes in defense spending across Europe. Under ReArm Europe / Readiness 2030, Member States aim to mobilize up to €800 billion to increase defense spending. Notably, the €150 billion SAFE fund specifically recognizes cybersecurity as a key investment area. There is a clear push to:

• boost Europe’s industrial capacity,
• enhance the resilience of supply chains, and
• reduce reliance on external sources.

This reflects a broader commitment to strengthening Europe’s security landscape.

As European countries increase defense investment, a growing share of it will need to support digital capabilities alongside conventional military hardware. Connected weapons systems, autonomous platforms, AI-enabled decision support, electronic warfare, sensor networks, and distributed command systems all depend on cybersecurity.

This broadens the opportunity beyond perimeter protection and traditional SOC services. Secure communications, identity, cryptography, post-quantum security, data protection, OT security, secure AI, and resilient infrastructure are becoming increasingly relevant components of modern defense architectures.

The value of specialist European cybersecurity companies may therefore also change. Smaller vendors can possess intellectual property, cryptographic expertise, accreditations, or access to sensitive environments that larger defense companies would need considerable time to build internally.

Given ongoing developments in ReArm Europe, we’re likely to see more mergers and acquisitions in the defense sector. European defense companies are increasingly motivated to acquire cybersecurity technologies to:

• fill capability gaps,
• secure critical components, and
• enhance their standing in national or joint European procurement initiatives.

While it’s not expected that every small niche in cybersecurity will merge into larger defense groups, we can anticipate that strategically important areas will attract more interest and investment.

This creates a dynamic competitive landscape for cybersecurity providers. Defense companies may increasingly be customers, partners, integrators, and competitors simultaneously.

For defense suppliers, the boundary between the physical platform and the digital security architecture is becoming less meaningful. Cybersecurity increasingly affects the operational effectiveness and competitiveness of the underlying defense system.

Terma’s purchase of Dencrypt is a targeted move, but it reflects a broader trend in the defense landscape. With initiatives like Readiness 2030 coming into play, the European defense market is evolving, driven by increased investment, industrial policies, and concerns about critical dependencies. Gaining control over secure communications and cryptographic technology has become crucial, offering strategic advantages that extend far beyond the cybersecurity products themselves.

Conclusion:

Terma’s acquisition of Dencrypt reflects a broader shift in European defense, in which secure communications, cryptographic control, and technological sovereignty are increasingly integral to operational capability. ReArm Europe is likely to reinforce this trend by increasing investment and elevating the strategic value of European cybersecurity assets.
