This week SonicWall announced its TZ and NSA product lines achieved the latest in government certification requirements, having earned the Common Criteria (CC) Evaluation Assurance Level 4+ (EAL4+) certification (ISO 15408). The new EAL4+ certification is an addition to the already achieved FIPS140-2 Level 2 certification (see article here). As any federal IT engineer will tell you, having the box checked on government requirements for compliance is critically for government acceptance and implementations.
