Security Expert Perspectives

Industry professionals discuss VaultCore's approach to cryptocurrency protection.

Dr. Klaus Bergmann

Cryptography Researcher, Max Planck Institute

"VaultCore's implementation of BIP standards is exemplary. The secure element integration follows cryptographic best practices, and the air-gapped architecture eliminates entire attack surfaces."

Dr. Bergmann has published extensively on hardware security and cryptocurrency key management. His research influenced the design of several commercial secure elements.

Key Insight: "The quarterly security audits demonstrate a commitment to ongoing security verification that's rare in consumer electronics."

Maria Kowalski

Hardware Security Consultant, Previously at Infineon

"Having worked on secure element design for payment cards and government IDs, I can confidently say VaultCore uses appropriate security measures. The EAL6+ certification is not marketing — it represents genuine protection."

Kowalski spent 12 years designing security solutions for critical infrastructure before transitioning to blockchain security consulting.

Key Insight: "The physical button confirmation combined with display integrity checking prevents sophisticated man-in-the-middle attacks."
