Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
SEALSQ INeS Managed PKI for IoT
Mid-market and enterprise teams deploying large IoT fleets will find real value in SEALSQ INeS for zero-touch onboarding and batch certificate provisioning to disconnected factories, where manual cert management becomes operationally impossible. The service covers the full NIST Identity Management and Platform Security functions through device attestation, automated lifecycle renewal, and native integration with AWS IoT Core and Azure DPS. Skip this if your IoT footprint is under a few thousand devices or if you need certificate management to double as a broader identity platform for non-IoT assets; INeS is purpose-built for device identity at scale, not workforce access.
Mid-market and enterprise security teams drowning in certificate sprawl across hybrid infrastructure should start here; Tanium Certificate Manager finds and monitors certificates you didn't know existed, which is half the battle most teams lose. The platform covers ID.AM and DE.CM functions meaningfully, giving you actual inventory visibility and continuous anomaly detection rather than point-in-time scanning. Skip this if you need deep certificate orchestration and renewal automation; Tanium excels at discovery and alerting, not at managing the remediation workflow end-to-end.
