Turn compliance checklists into verifiable attestations. An open source platform to map controls to standards, collect evidence, and exchange results machines can verify and humans can trust.
From high-level compliance dashboards to granular assessment workflows, Assessors Studio gives every stakeholder the view they need.
Widget-based dashboard surfaces conformance posture, assessment progress, and risk insights across your organization.
Visualize organizational structures, suppliers, products, and their assessment relationships in an interactive graph.
Step through standards, evidence, claims, and attestation generation with full traceability at every stage.
Built for modern assurance workflows. Assessors Studio replaces spreadsheets and static reports with structured, machine-readable, verifiable artifacts.
Conduct repeatable assessments aligned to defined requirements, with workflow support for contributors, reviewers, and approvers.
Attach documentation, scan results, test artifacts, and third-party reports directly to claims while preserving provenance.
Express conformance statements in a standardized format that downstream systems can parse, validate, and automate against.
Generate CycloneDX attestation documents consumable by governance, risk, compliance, and security automation platforms.
Support for both electronic and cryptographic digital signatures enables flexible deployment from internal approvals to legally binding attestations.
Import and manage machine-readable standards. Map internal controls to recognized frameworks and generate attestations aligned to multiple standards.
The CycloneDX attestation model structures assurance around four core primitives.
Import standards and define what must be satisfied. Map requirements to recognized compliance frameworks.
Assert conformance in a structured, standardized format. Reference supporting and counter evidence with mitigation strategies.
Attach artifacts that substantiate claims. Scan results, documentation, test reports, and third-party attestations.
Produce machine-readable, signed attestation documents ready for automated validation and exchange.
Assessors Studio works as a hands-on platform and as a node in your automated infrastructure. Every workflow that runs through the UI can also run through code, pipelines, and cross-system integrations.
Every capability exposed through the UI is also available programmatically. Build integrations, trigger assessments, and retrieve attestations through a consistent, well-documented API surface.
Embed attestation generation directly into CI/CD workflows. Validate compliance gates, produce signed artifacts, and propagate trust signals as part of every build and release.
Exchange attestations across organizational boundaries through transparency ecosystems like the Transparency Exchange API (TEA). Consume and produce artifacts that any compliant system can verify independently.
