NIST SP 800-53 Rev 5

IA-2(6) Identification and Authentication — Network Access — MFA

Phishing-resistant MFA using hardware security keys. Software TOTP and SMS are explicitly excluded from "phishing-resistant" in NIST 800-63B and most modern framework guidance.

SC-12 Cryptographic Key Establishment and Management

Hardware-bound key generation and storage. Private keys generated and stored inside a certified secure element (EAL 6+) and are non-exportable by design.

AC-19 Access Control for Mobile Devices

Hardened mobile OS with per-app sensor controls, verified boot, and no background telemetry. Satisfies mobile device management and bring-your-own-device security requirements.

SI-7 Software, Firmware, and Information Integrity

Measured boot chain verified on every power-on. Any firmware modification — supply chain implant, evil-maid attack, or malicious update — fails attestation before the OS loads.

SC-3 Security Function Isolation

VM-level compartmentalization means a compromise of one domain (e.g. browser) cannot reach another (e.g. keys, vault). No other consumer laptop provides this by default.

SC-7 Boundary Protection

Stateful firewall with IPS at the network perimeter. All inbound/outbound traffic inspected with Suricata rule sets. VPN gateway replaces consumer VPN dependency.

Products that satisfy this control:

SC-28 Protection of Information at Rest

Hardware-encrypted storage and self-hosted file servers replace cloud storage with hardware you control. Encryption keys never leave your environment.

SR-3 Supply Chain Controls and Processes

Open-source firmware is publicly auditable and reproducibly built. EU jurisdiction hardware is not subject to US National Security Letters. Directly addresses hardware supply chain risk in CMMC and NIS2.

PE-3 Physical Access Control

Rated safes and vaults protect physical assets, documents, and hardware backups. UL-certified fire and burglary ratings provide auditable physical security controls.

Products that satisfy this control:

SC-8 Transmission Confidentiality and Integrity

Verified boot ensures the TLS stack is unmodified before communication. VPN gateway encrypts all remote access traffic. Hardware-backed keys prevent interception even if endpoints are observed.
