Hardware-rooted identity for workforce access, high-risk approvals, and enterprise trust.
Hardware-rooted identity for workforce access, high-risk approvals, and enterprise trust.
Workforce & Privileged Access Assurance
Protects access to systems, admin functions, and sensitive operations on enterprise-issued or managed devices. Prevents credential compromise, insider misuse, and unauthorized escalation.
Ideal for—Organizations where human access alone can cause systemic failure.
Outcome—Deterministic, auditable enforcement of workforce and privileged access decisions.
High-Risk Internal Approvals and Transactions
Secures treasury actions, wire approvals, and other high-impact financial or operational decisions. Replaces spoofable or phishable approval mechanisms with hardware-enforced authorization.
Ideal for—Organizations where a single approval moves money or creates irreversible exposure.
Outcome—Deterministic, auditable approval of high-risk financial and operational actions.
Enterprise-Oriented Trust Artifacts
Verifies the authenticity and provenance of enterprise-issued instructions, credentials, and attestations. Binds origin, delivery, device, and network integrity to prevent spoofing and replay attacks.
Ideal for—Organizations where enterprise-issued instructions must be provably authentic.
Outcome—Deterministic, auditable enterprise-issued trust artifacts.

Multi-Signature (Multi-Sig) High-Risk Approval Flow
For sensitive actions such as large fund transfers, privilege escalations, or executive overrides, SLC Guardian supports multi-sig authorization, requiring confirmation from multiple trusted devices or approved users before execution.
