Evidence Vallum Produces
Authentication event receipts, identity-verification records, and credential-lifecycle evidence
Evidence Vallum Does NOT Produce
Biometric verification data, physical identity documents, or multi-factor device attestations
Known Limitations
Vallum produces evidence relevant to this control but does not enforce the control at the infrastructure, network, or operating-system level. Evidence covers Vallum-managed operations only. Customer systems, third-party integrations, and infrastructure controls require separate evidence sources.
Your Responsibilities
Manage identity provider, enforce multi-factor authentication, establish credential policies, and handle identity lifecycle
External Controls Required
Identity provider (IdP), network firewall and segmentation, infrastructure monitoring, endpoint protection, and organizational security policies
Residual Risk
Vallum evidence covers authorization and evidence-layer operations. Gaps exist at infrastructure, network, and physical layers that require complementary controls. Time-of-check to time-of-use windows exist between evidence capture and verification.
