Apricorn Aegis Secure Key 3NXC
Best for: Government agencies and defense contractors requiring FIPS Level 3
The Aegis Secure Key 3NXC is one of very few flash drives with FIPS 140-2 Level 3 validation, meeting the strictest government and military data protection requirements. The physical keypad is tamper-evident and the drive self-destructs data after configurable failed attempts.
Why we like it

- Physical keypad with tamper-evident epoxy coating
- Configurable brute-force lockout and data destruction
Flaws

- Fingerprint scanner eliminates PIN entry hassle
- Compact credit-card-sized design
Flaws
- Not FIPS-certified for government compliance

BUYING GUIDE
Hardware vs Software Encryption
Hardware encryption uses a dedicated chip on the drive to encrypt/decrypt data, making it immune to software-based attacks and keyloggers. Software encryption relies on your computer's CPU and can be vulnerable to certain attacks. For truly sensitive data, always choose hardware-encrypted drives with FIPS certification.

FIPS Certification Levels Explained
FIPS 197 certifies the encryption algorithm (AES). FIPS 140-2 Level 2 adds tamper-evidence and role-based authentication. Level 3 adds tamper-resistance with physical mechanisms that zero out keys if the device is opened. For government and military compliance, Level 3 is typically required.
