Evidence Vallum Produces
Encryption-status evidence, boundary-enforcement receipts, and key-management lifecycle records
Evidence Vallum Does NOT Produce
Network traffic analysis, TLS certificate management records, or firewall rule configurations
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 TLS certificates, configure network boundaries, implement encryption at rest for infrastructure, and maintain key management infrastructure
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.
