Quantum computers will break today's encryption. The transition starts now.
As quantum computing edges closer to breaking the encryption that underpins modern digital life, the window for preparation grows narrower with each passing season. NEXCOM, a Taipei-based network hardware maker, has answered this civilizational inflection point with the FTA 5190 — a compact edge server engineered to carry the mathematical weight of post-quantum cryptography without burdening the networks it protects. The machine arrives not as a solution to a future problem, but as a bridge across the difficult present, where old and new encryption standards must coexist and neither can afford to fail.
- Quantum computing is advancing faster than most enterprises anticipated, threatening to render today's encryption obsolete before organizations have finished replacing it.
- Post-quantum cryptographic algorithms demand significantly more computational power than their predecessors, creating a performance crisis for infrastructure not built to absorb the load.
- NEXCOM's FTA 5190 deploys Intel QuickAssist Technology to offload encryption operations onto dedicated hardware, freeing processors for AI, analytics, and the other work edge servers must still perform.
- In testing, the server sustains up to 3,500 post-quantum connections per second per core and delivers more than double the throughput of earlier systems in hybrid encryption environments.
- The device is designed for the transitional moment — supporting legacy and quantum-resistant standards simultaneously so organizations can migrate without forcing painful trade-offs or service disruptions.
Quantum computers are coming, and when they arrive at scale, they will shatter the encryption guarding most of the world's digital secrets. The threat is not purely hypothetical — it is already reshaping how enterprises plan their security infrastructure. Post-quantum cryptography offers a defense, but its algorithms are mathematically heavier than anything they replace, demanding larger keys, more complex computations, and hardware capable of absorbing that burden without choking the networks that depend on it.
NEXCOM, headquartered in Taipei, has built a machine for precisely this transition. The FTA 5190 is a compact edge server — roughly pizza-box dimensions — powered by Intel's Xeon 6 processors with up to 36 performance cores per chip, 128 gigabytes of DDR5 memory, and a dense array of high-speed network ports. It is designed to sit at the perimeter of enterprise networks, handling encryption for thousands of simultaneous connections without becoming a bottleneck.
The key to its performance is Intel's QuickAssist Technology, which delegates cryptographic operations to specialized hardware rather than consuming the main processor cores. This keeps those cores available for machine learning, real-time analytics, and the other workloads modern edge infrastructure is expected to run concurrently. NEXCOM's benchmarks place the server at 3,500 post-quantum connections per second per core, with throughput in hybrid deployments — running both traditional and quantum-resistant encryption at once — running more than twice that of comparable systems.
That hybrid capability is the point. Enterprises cannot abandon legacy encryption overnight; old systems must remain functional while new ones come online. The FTA 5190 is engineered for this complicated middle ground, where organizations must honor both the infrastructure they have and the security standards they are moving toward — carrying heavy traffic across a bridge that cannot afford to buckle.
Quantum computers are coming, and they will break the encryption that protects most of the world's secrets today. This is not a distant threat—it is reshaping how enterprises think about security right now. As quantum capabilities advance, organizations are scrambling to adopt post-quantum cryptography, a new class of algorithms designed to resist attacks from machines that don't yet exist at scale. The problem is that these new encryption methods demand far more computational power than the systems they replace. They require larger encryption keys, more complex mathematics, and infrastructure that can handle the load without slowing down the networks that depend on it.
NEXCOM, a Taipei-based maker of network appliances, has built a machine designed specifically for this transition. The FTA 5190 is a compact edge server—about the size of a pizza box—built to handle post-quantum cryptography workloads without sacrificing the performance that enterprises need. It runs on Intel's latest Xeon 6 processors, which can pack up to 36 performance cores into a single chip. The server supports up to 128 gigabytes of DDR5 memory and includes eight high-speed 25-gigabit network ports, along with eight standard gigabit ports and room for additional network modules. For a machine designed to sit at the edge of a network, handling encryption for thousands of simultaneous connections, this is a dense concentration of capability.
The real innovation lies in how the FTA 5190 handles the computational burden of post-quantum algorithms. It uses Intel's QuickAssist Technology, a hardware acceleration feature that offloads cryptographic operations from the main processor cores. This matters because post-quantum encryption is mathematically heavier than what came before. The algorithms use larger key sizes and more complex computations. Without acceleration, processing all that encryption would consume CPU resources needed for other tasks—machine learning models, real-time analytics, the work that modern edge servers are actually supposed to do. By delegating encryption to specialized hardware, the FTA 5190 keeps the main processors free.
NEXCOM's testing shows what this means in practice. The server can handle up to 3,500 post-quantum cryptographic connections per second per processor core. In hybrid deployments—networks running both traditional and post-quantum encryption simultaneously—it delivers 2.1 times higher throughput than comparable systems. With conventional encryption, the improvement is even more dramatic: up to twice the performance of earlier generations. These are not marginal gains. They are the difference between a transition that feels seamless and one that forces painful trade-offs.
The timing is deliberate. Quantum computing is advancing faster than many expected, and the window for preparing infrastructure is narrowing. Enterprises cannot simply flip a switch and move to post-quantum cryptography overnight. Legacy systems must keep working. New systems must be compatible with old ones during the transition. Networks must maintain performance while adding the computational overhead of stronger encryption. The FTA 5190 is built for exactly this moment—not for a quantum future that may be years away, but for the messy, complicated present where organizations must support both old and new encryption standards simultaneously. It is a bridge, and it is built to carry heavy traffic.

The Hearth Conversation Another angle on the story
Why does quantum computing break encryption that works fine today?
Quantum computers can solve certain mathematical problems exponentially faster than classical computers. Current encryption relies on problems that are hard to solve—factoring large numbers, for instance. A quantum computer could crack that in hours. Post-quantum algorithms use different math that even quantum computers can't easily break.
So why not just wait until quantum computers are actually a threat?
Because encrypted data stolen today can be decrypted later. If someone records your encrypted communications now and quantum computers arrive in five years, they can go back and read everything. Organizations need to encrypt with quantum-resistant methods today, even if the threat feels distant.
That sounds expensive and complicated.
It is. Post-quantum encryption is computationally heavier. It demands more processing power, more memory, more network bandwidth. If you just bolt it onto existing infrastructure, everything slows down. That's where a purpose-built server like the FTA 5190 comes in—it's designed so the slowdown doesn't happen.
How does it avoid the slowdown?
Hardware acceleration. The server has specialized circuits that handle encryption operations in parallel, separate from the main processors. The main CPUs stay free to do other work—analytics, machine learning, whatever the edge server is actually supposed to be doing.
Who actually needs this right now?
Any organization running distributed networks with sensitive data—financial institutions, healthcare systems, government agencies, large tech companies. They're already being pushed by regulators and security standards to start the transition. This server lets them do it without rebuilding their entire infrastructure.
What happens if they don't prepare now?
They're vulnerable to a specific attack: harvest now, decrypt later. And when regulations finally mandate post-quantum encryption—which is coming—they'll face a costly, rushed migration instead of a planned one.
