CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Individual privacy advocates and security researchers who need genuine iOS isolation will find StealthOS valuable for its anti-fingerprinting implementation and encrypted peer-to-peer messaging that actually compartmentalizes data from the OS kernel. The free pricing model removes barrier to experimentation, though deployment remains limited to personal devices rather than organizational fleets. Skip this if you're a security team looking for MDM-integrated mobile data protection; StealthOS prioritizes individual privacy over enterprise control and compliance reporting.
Enterprise and mid-market defence contractors need Armour Mobile specifically for classified comms that satisfy NATO and UK government approval without custom integration hell. NATO Restricted and OFFICIAL SENSITIVE clearance baked in, plus FOI-compliant audit trails and device revocation, means you skip the certification delays that kill typical commercial platforms in this space. NIST Identity Management and Data Security coverage is solid, though the feature set tilts heavily toward secure transport rather than zero-trust device posture; if your threat model centres on endpoint compromise before the encrypted channel, you'll need layered defences elsewhere. Wrong choice for non-defence organizations or anyone without classification requirements.
