Randomness You Can SeeSecurity You Can Trust

Real Random generates true entropy from patented physical hardware for cryptography and other security applications — not algorithms, not silicon you take on faith. Unpredictable to any computer, classical or quantum, and the foundation your post-quantum migration depends on.

Why Now

The Entropy Refresh is Mandatory

Entropy is the one cryptographic component you can't patch in software. As FIPS 140-3, CNSA 2.0, and downstream PCI / financial mandates force module re-validation, regulated industries face a multi-year entropy-source refresh — 2027 to 2029.

Sep 2026

FIPS 140-2 sunset

Validated modules must move to FIPS 140-3 — entropy gets scrutinized. Buyers must act now.

Jan 2027

CNSA 2.0

U.S. national-security systems adopt quantum-resistant algorithms that require more entropy.

2027–2029

Refresh cycle

Enterprise + government re-validation across regulated industries in years not decades.

Recent Examples of Weak Entropy Failing

When a sealed entropy source attests its own output, a silent failure looks identical to success — exactly what happened to AMD's RDSEED in 2025. (CVE-2025-62626) Read the AMD security bulletin

1 in 172 RSA certs scanned across the public Internet shared a prime factor… the cause wasn't RSA; it was insufficient entropy. Read the Keyfactor IEEE paper

Seeing Is Believing

True entropy, not a black box.

That's why we've built a tangible solution using the natural dynamics of physical randomness. “Random” number generators (RNGs) typically use mathematical algorithms to produce digits — meaning they're actually only pseudo-random. In today's hackable online world, pseudo is dangerous. True entropy lies in the unpredictable physical world, where human and digital intervention are withheld.

Side-by-side comparison: a true random number generator's output looks like even noise, while PHP's pseudo-random generator on Windows shows visible vertical striping patterns

The Solution

Physical Entropy.
Verifiable Trust.

Meet the mandate without a multi-year hardware program. Real Random drops into your stack as a service — true physical entropy, delivered the way modern teams ship everything else.

Our hardware, your location

Access true randomness where you need it without passing over open networks.

Integrate in 4 lines of code

Drop our REST API into any application or pipeline.

Secure in hours, not months

From sign-up to live entropy the same day — no procurement cycle.

Subscription that scales

Pay per protected endpoint; capacity grows with you.

How It Works

From Physics to Protection

Four steps take raw physical chaos and turn it into auditable entropy your systems can trust, end to end.

Try the Interactive Demo

Physical Generation

Precision dice tumble through viscous fluid inside patented hardware, producing chaotic motion no computer can model or predict.

Real-Time Capture

High-resolution optical sensors read position, rotation, and collision data, converting physical chaos into raw entropy.

Quality Assurance

Continuous statistical validation confirms every output meets the highest randomness standards before delivery.

Secure Delivery

Entropy flows through an encrypted REST API or your on-prem hardware into your cryptographic stack, with a full audit trail.

Deployment

Adopt in Hours, Not Months

Consume true entropy the way your architecture needs it. Three delivery models, one patented source. Start with the API to prototype, deploy hardware when you scale.

Entropy-as-a-Service

True physical entropy through a REST API, accessible from our developer portal. Prototype against your actual stack before procurement enters the room, evaluation to approval in weeks, not quarters.

2U Server Rack Appliance

Rack-mounted generators deployed inside your secure facility. Same patented technology, zero external dependencies, and a FIPS 140-3 validation pathway.

Portable Hardware

A compact, ruggedized generator built to move. The same patented entropy source, hardened against vibration, temperature, and shock, with no network dependency.

Why We Win

Faster. Simpler. Provable.

U.S.-built entropy source — easier to adopt, lower in cost, and the only one you can independently verify. Real Random makes it possible to meet the coming compliance requirements for entropy without a rip-and-replace operation.

Faster

Integrate in 4 lines of code. Live entropy in hours — no procurement, no rack-and-stack.

Simpler

On-prem or API, delivered as a subscription. We handle the hardware — you get the entropy.

Provable

The only transparent entropy source. We make “trust, but verify” possible.

Use Cases

Built Where the Stakes Are Highest

When predictable randomness isn't an option, these teams choose physical entropy.

Every transaction, tamper-proof

Financial Services

Systems moving billions a day can't run on entropy that's “good enough.” From HSM key generation to fraud detection, this is the cryptographic foundation regulators and auditors trust.
