Identity
Explicit authorization for people, workloads, services, devices, and nodes.
Platform / Security
Security claims scoped to the system that earned them
Talvium is developing repeatable controls for identity, attestation, private networking, encryption, key custody, confidential processing, supply chain, change control, incident response, and evidence.
Controls under development
No blanketcertification claims

Evidence matrix
Approval is a stack, not a badge
A facility, information system, network connection, and contractor can each require a different decision owner. Talvium's role is to make the evidence chain repeatable, not to collapse those decisions.
| Layer | Decision owner | Talvium evidence |
|---|---|---|
| Mission and sponsorship | Customer, contracting activity, or qualified prime | Use case, sponsor map, and acquisition path |
| Entity and personnel | Cognizant security and vetting authorities | Entity structure, eligibility, and personnel package |
| Facility | Responsible accrediting authority | Reference design, site delta, tests, and findings |
| Information system | Authorizing official | Boundary, controls, assessment, risk decision, and monitoring |
| Network connection | Network owner and mission authority | Interface, identity, keying, routing, and operating procedures |
| Operations and change | Sponsor and oversight authorities | Configuration history, incidents, maintenance, and reapproval triggers |
Capability set
Platform security domains
Attestation
Verify configuration, hardware state, software state, and approved provenance.
Keys
Platform, customer-managed, or dedicated custody patterns declared by service.
Network
Private paths, segmentation, approved interfaces, and cross-domain control.
Operations
Personnel access, maintenance, incident, vulnerability, and change evidence.
Confidential processing
Attested protection for approved workloads and data in use.
Evidence note
Zero trust is an architecture, not a product label
The design follows the NIST principle that location or ownership does not grant implicit trust. Every resource request remains an explicit policy decision.
