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
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.

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 DemoPhysical 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.
Traction
Trusted Where Randomness Can't Fail
Security teams in defense, finance, and high-assurance software choose Real Random when predictable randomness isn't an option.
