The defense sector was once a niche market reserved mostly for governments and legacy contractors. Now, defense tech is one of Europe's fastest-growing innovation sectors.
Modern defense tech is about much more than military equipment—it integrates AI-powered intelligence, satellite systems, cybersecurity and much more.
With Europe racing to close its defense innovation gap, the startups, technologies, and policies shaping this sector today will define the continent's security for generations to come.
What Is Defense Tech, and Why Is It Rising Now in Europe?
Defense tech refers to technologies developed to improve national security, defense capabilities, and critical infrastructure resilience.
Traditional defense focused on hardware such as aircraft, ships, and armored vehicles. But defense tech startups also develop software, AI, robotics, sensors, satellites, and cyber defense.
From Niche Sector to Strategic Priority
Russia's invasion of Ukraine fundamentally changed Europe's security priorities, says Philippe Adam, a former general in the French Air Force and president of consulting business PhAS Conseil.
"In 2022, we all realized that real war still can happen,” Adam said on stage at VivaTech 2026. “Of course, the war of the future will be different from the wars of the past. But certainly, what we called a high-intensity war can happen again in Europe. And we are not ready for that.”
At the same time, increased cyberattacks against governments, healthcare systems, financial institutions, and critical infrastructure are evidence that modern conflicts often begin online before ever reaching physical borders.
This has led to growing recognition in Europe that tech leadership is inseparable from strategic defense, explains Cesare Battaglia, an aerospace and defense leader at PwC: "The meaning that defense acquired over the last years that is no longer military, but it's much more tech related, resilience-related, autonomy, sovereignty, and so on."
In response, governments are investing in modernizing their armed forces, but also in securing Europe's digital infrastructure, industrial competitiveness, and long-term resilience.
The Forces Driving Europe's Defense Tech Boom
Several structural trends are driving the sector's rapid growth:
- Artificial intelligence is transforming intelligence gathering, logistics, autonomous systems, and decision support.
- Advances in robotics are accelerating the deployment of autonomous ground vehicles and drones.
- Space technologies improve communications, navigation, and surveillance.
- Cybersecurity has become a frontline defense capability.
The private sector also plays a larger role than in previous decades. Venture-backed startups develop technologies that governments once built internally, shortening innovation cycles and bringing commercial expertise into national security.
How Much Is Flowing Into European Defense Tech?
Venture capital firms used to largely avoid the defense tech sector, but are increasingly backing startups that develop dual-use technologies with both commercial and defense applications.
Record Funding Across Defense, Security, and Resilience
Investment in European defense tech has accelerated dramatically over the past several years. In 2025, European defense, security, and resilience startups raised $8.7 billion—a 4x increase over 2020. The sector now makes up about 10% of all European venture capital funding.
This shift reflects a change in investor sentiment. "There's lots of money that is going there,” says Battaglia. "But there's also a significant understanding of what defense now means in terms of technological spillover, direct and indirect impact on the real economy, new skills, new technologies, and development."
Public investment has also expanded. The European Union, national governments, and NATO are channeling significant resources into emerging technologies designed to strengthen European resilience.
Where Late-Stage Capital Is Heading
Later-stage capital is increasingly concentrating around companies capable of scaling internationally.
Investors are prioritizing startups with technologies that address multiple markets—everything from defense and aerospace to industrial automation, cybersecurity, and critical infrastructure protection.
Many technologies used daily by civilians began as defense projects. For example, the internet, GPS, and microwaves were all tools initially built for military use before becoming expanding to the general public. This dual-use model reduces dependence on government procurement while expanding commercial opportunities.
Which Startups Are Leading Europe's Defense Tech Shift?
Let’s look at a few startups that are strong examples of Europe's new approach to defense innovation.
Helsing, TEKEVER, and ARX Robotics: Scaling AI and Robotics for Defense
Helsing has become one of Europe's highest-profile AI defense companies. The German defense startup develops AI software that transforms sensor data into real-time intelligence for military decision-making.
TEKEVER specializes in autonomous drone systems used for maritime surveillance, border security, and intelligence gathering. The Portuguese company is now a leading European provider of AI-enabled unmanned aerial systems (UAS) and autonomous intelligence.
ARX Robotics develops autonomous ground vehicles designed to improve logistics, reconnaissance, and operational efficiency while reducing risk for personnel. The German company’s systems are on the frontlines in Ukraine and used across NATO forces.
These companies showcase a broader trend in European defense tech: the development of highly adaptable solutions that combine AI, robotics, software, and advanced manufacturing.
How NATO's Innovation Fund Is Backing the Next Wave
The NATO Innovation Fund invests directly in deep tech startups working across AI, quantum computing, advanced materials, energy resilience, space technologies, and cybersecurity.
Alongside NATO’s innovation accelerator DIANA, the innovation fund provides startups with access to funding, testing environments, technical expertise, and defense customers. All of these are resources that have been historically difficult for early-stage companies to access.
By connecting governments, investors, researchers, and entrepreneurs, these programs aim to accelerate commercialization while strengthening Europe's long-term tech competitiveness.
Why Cybersecurity Is Now Inseparable From Defense Tech
Modern defense extends beyond physical borders.
Hybrid Threats and the Rise of Digital Warfare
Cyberattacks targeting governments, hospitals, transportation networks, financial institutions, and energy providers have made it clear that digital infrastructure is now also critical national infrastructure.
Everyone from nation-state actors to organized criminal groups and hacktivists are a part of today’s complex threat landscape.
This has made cybersecurity one of defense tech's fastest-growing segments. AI-powered threat detection, real-time monitoring, identity protection, secure cloud infrastructure, and automated incident response are all essential parts of national resilience.
Building Europe's Cyber Resilience Through the AGILE Plan
Europe is increasingly combining investment with coordinated policy.
In recent years, the EU has launched several initiatives to encourage collective resilience across member states:
- The EU Cybersecurity Strategy aims to build cyber threat resilience for essential services such as hospitals, energy grids, and railways, and outlines how the EU can collectively detect, prevent, and respond to major cyberattacks.
- The Cyber Solidarity Act was implemented to strengthen the EU’s ability to detect, prepare for, and respond to significant and large-scale cybersecurity threats and attacks.
- The AGILE program is the European Commission's €115 million defense technology innovation accelerator. It is designed to bring disruptive defense technology such as AI, quantum, and drones from the lab to the field at record speed.
From Awareness to Action: How Startups Are Closing the Gap
Startups play an increasingly important role in Europe's cyber resilience. Many specialize in AI-driven security operations, secure communications, cloud security, identity management, industrial control system protection, and automated threat intelligence.
European defense startups also help governments and EU defense giants like Airbus and Saab develop more innovative solutions, explains Lithuania’s Vice-Minister of Finance Januš Kizenevic: "The long-term thing is to not only strengthen these companies and extend production capabilities, but also to connect these European champions with the smaller, very innovative companies from other countries that really develop very sophisticated products—cyber security, laser, and other very niche areas—that are required to build strong defense systems.”
What Does Defense Tech Mean for Europe's Sovereignty?
One of Europe's main goals is to reduce strategic dependence on external technologies.
Reducing Dependence on Non-European Suppliers
Policymakers understand that technological autonomy is directly tied to national resilience. That’s why Europe is focused on building homegrown suppliers of semiconductors, cloud computing, AI models, satellite communications, and cybersecurity infrastructure.
Strengthening domestic innovation doesn’t mean Europe is closing itself off from global partnerships. But for long-term security and competitiveness, it is critical that Europe reduces its technological dependence on the U.S. and China.
Aligning Capital, Policy, and Innovation
Achieving that goal requires coordination across European governments, investors, industry, research institutions, and startups.
"It's not everything to have a lot of money to spend, it's also to spend it wisely," advises Adam. “We have to adapt to this world, and we have to recognize that our procedures were built for a world that was largely at peace. The wars we were preparing to fight were completely different than the ones that we need to prepare to fight now.”
Alongside regulatory clarity, fostering skilled talent, and providing opportunities for startups to scale, increasing the speed of innovation also needs to be a priority.
So, Is Defense Tech a Security Risk or Europe's Sovereignty Engine?
Defense technologies inevitably raise ethical, regulatory, and geopolitical questions.
Why the Opportunity Outweighs the Risk
For startups and investors, there is a major opportunity to develop innovations that strengthen both economic competitiveness and public security. But time is of the essence.
"The opportunity window is open, but it's open now,” says Battaglia. “We have in front of us 12 to 24 months in order to position. The need and the challenges will be in the stable and structure for 10 to 15 years. But the move has to be done now because the first mover gets a significant advantage."
Europe has to strike the tricky balance of ensuring AI, autonomous systems, cybersecurity governance, and international cooperation are deployed responsibly, while not slowing down this innovation.
What Comes Next for Investors and Innovators
The key to defense tech success for Europe lies in cooperation, says Adam: “The common interests of Europe really require that we stop competing a little bit with each other. The competition will still be there, of course. But we need to make sure that we can also unite efforts when it comes to our real interests in the future.”
Europe has the talent, capital, and partnerships needed to build the next generation of security technologies. Now the challenge is keeping that innovation growing on European soil.
