SecuraVouch Credential Assurance
Controlled pre-release. SecuraVouch is not yet generally available through Microsoft Marketplace. Reference Action Packs demonstrate policy-bound authorization and evidence generation; they do not execute privileged, financial, supplier-record or information-release actions unless a separately reviewed customer connector has been deployed.

SECURITY DESIGN

Fail closed. Bind narrowly. Prove what happened.

SecuraVouch is designed around explicit trust boundaries rather than implicit approval from presence, urgency or a single application event.

Fail-closed authorization

Expired, invalid, missing or insufficient identity and authority evidence does not silently downgrade into approval.

Identity ≠ presence

Microsoft Teams meeting context is treated as origin evidence, not proof of physical identity or organizational authority.

Exact-action binding

Decisions and permits are bound to the protected action they were issued for, reducing approval-reuse ambiguity.

Separation of principals

Policies can require distinct authority holders and prevent a single principal from satisfying multiple policy-distinct roles.

Time-bounded permits

Authorization permits are deliberately short-lived and expire rather than remaining reusable authorization artifacts.

Tamper-evident evidence

Structured evidence and cryptographic integrity mechanisms support later verification of assurance events.

Protected meeting references

Sensitive external meeting and participant references are protected by application-level cryptographic controls before persistence.

Minimal device access

The Teams application does not request camera or microphone device permissions for its credential-assurance workflow.

Logging hygiene

Authentication failures are designed to emit diagnostic status without exposing raw bearer tokens in normal application logging.

Trust boundary

SecuraVouch provides authorization assurance for configured workflows. It does not claim that collaboration-platform presence alone proves the physical identity of a person, and it does not infer authority from meeting membership. It makes no biometric, liveness, physical-presence, qualified-electronic-signature or universal deepfake-detection claim. Its research-only physical-channel experiments are not part of the current product surface.

Current validation boundary

Local automated tests exercise implemented authorization, evidence and marketplace trust boundaries. Native execution in a controlled Microsoft 365 tenant and customer-specific downstream connectors remain separate release gates. No public statement on this site should be read as a certification of a customer's configuration or regulated workflow.

Responsible disclosure

Security researchers can report suspected vulnerabilities to info@securagen.ai. Please do not include passwords, bearer tokens, private keys or other live secrets in an initial report.
