Cyber security
# Cybersecurity, Quantum and the Future of Defense
In recent years, the conversation around defense and critical
infrastructure has shifted dramatically. Cybersecurity is no longer treated as a last priority in development. Instead it has become a foundational element.
This shift reflects a time where threats evolve quickly and technologies mature faster than anticipated.

Written by: [Terma](https://blog.terma.com/author/terma)
### From Extra to Standard
Traditionally, cyber was seen as something “extra” when the core system was built. Today, organizations recognize that resilience must be designed into systems from the start. Cybersecurity supports the entire life cycle of defense platforms. It ensures that once it’s delivered, it remains secure in the environments where it operates.
This evolution is very important. Defense is about protecting systems with interoperability across borders and allies. Common standards, such as those defined by NATO, are crucial to ensuring secure communication and collaboration.
### The Convergence of Emerging Technologies
Artificial intelligence, quantum computing, and other disruptive technologies are developing faster than traditional defense planning can keep up. They offer new opportunities, but also serious risks.
- **AI**: It’s already integrated into everyday life. AI brings efficiency and new capabilities, but it also raises questions of trust, integrity of training data, and the risks of misuse.
- **Quantum**: Beyond its promise, quantum computing carries the threat of breaking today’s encryption.
- **Cyber**: Once purely defensive, cyber has become both shield and sword. Attacks on critical infrastructure are a clear sign that offensive capabilities are growing.
The defense and critical infrastructure sectors must not only explore the benefits of these technologies but also weigh their risks. For a deeper perspective on managing emerging threat, listen to [Samant Khajuria and Jeffrey Saunders discuss mitigation of risks](https://blog.terma.com/digital-warfare-in-the-age-of-ai-and-quantum-computing).
### Preparing for Quantum
Quantum computers that can break today’s encryption doesn’t exist yet. The problem here is , we can’t wait until it does. Enemies are already saving encrypted data now and plans to unlock it later. We call this strategy: *harvest now, decrypt later.*
To counter this, organizations are exploring post-quantum cryptography and quantum key distribution. Some solutions are already being tested, and modular security systems will make it easier to move to quantum-safe technology. But there are still challenges ahead. A lot of today’s systems are outdated and not easy to swap out. We need solutions that let classical and quantum methods coexist, not simply replace each other. Technology alone isn’t enough. Building the right skills in the workforce is just as essential.
### Collaboration Is Key
It requires more than individual effort to meet the challenges. Defense and infrastructure providers now lean on partnerships that span industries, universities, and national borders. By sharing intelligence, advancing research and removing barriers, they actively build resilience against disruptive innovation.
Such collaboration both strengthens today’s defenses, and lays the foundation for a more resilient and secure future.
### Looking Ahead
The future of defense will be shaped by how well we balance speed, innovation and security. Clear strategies, strong partnerships, and proactive adoption of emerging technologies will define readiness in the years to come.
Cybersecurity and quantum are not distant threats but present realities. By acting now, we do not only protect us against present risks but also secure a stronger, more resilient future.
