When choosing an access control system, data security matters. While cloud solutions are gaining popularity, CDVI’s ATRIUM KRYPTO system stands out as a powerful on-prem option —giving you full control over your data without relying on third parties, all while delivering advanced, built-in protection.

What makes ATRIUM KRYPTO different? It is a “ready-to-use” high-security solution that protects your infrastructure end-to-end, ensuring card cloning is a thing of the past. Read on to discover more of ATRIUM KRYPTO’s benefits and advantages:

 

1. End-to-End Military-Grade Encryption

KRYPTO’s security is impenetrable. The system uses AES128 encryption between the credential and the reader, and it escalates to AES256 from the reader to the A22K IP controller. This architecture ensures that every communication point is shielded against external attacks.

2. Unique Authentication Keys per Site

Unlike other systems, KRYPTO automatically generates unique authentication keys and an exclusive Application Identifier (AID) for each installation. This means your digital keys are yours alone, eliminating generic vulnerabilities.

3. Instant High Security

KRYPTO combines high-level security with true simplicity. No advanced programming or lengthy configuration is required—the system is designed to deliver maximum protection right out of the box, making installation faster and everyday use seamless.

4. No Subscription Fees

The ATRIUM software and firmware updates are all included and completely free of charge, so you can maintain full control of up to 500 doors and 10,000 users without paying monthly fees. Additionally, our KRYPTO Mobile-Pass, combined with ATRIUM BT app, allows users to unlock doors directly from their smartphones—without recurring platform usage fees.

5. Complete Ecosystem

ATRIUM KRYPTO delivers a complete access control ecosystem—from controller to credential—built to work seamlessly together. Each component is designed within the same environment, eliminating compatibility issues and simplifying installation. This unified approach ensures consistent performance, strong security, and a smooth experience for both installers and users. With no need to source or integrate third-party elements, projects move faster and operate more reliably.

Conclusion

ATRIUM KRYPTO sets the standard for on-prem access control—combining advanced security, simple installation, and intuitive day-to-day use. With a complete ecosystem from controller to credential, it’s a reliable, no-nonsense solution that puts you fully in control.
