# Statement of Applicability

> ISO 27001:2022 Annex A control mapping — which controls apply to Denialbase, which are implemented, and where the evidence lives.

<Info>
  The Statement of Applicability (SoA) is a required ISO 27001 document that lists every Annex A control, states whether it applies to our ISMS, records the implementation status, and points to the evidence. This page is the public summary; the full SoA (with sensitive evidence paths) is available under NDA.

**Last reviewed**: April 2026 · **Version**: 0.9 (draft, targeted GA Q2 2026) · **Owner**: Security Officer

## Scope of the ISMS

The Denialbase Information Security Management System (ISMS) covers:

* The Denialbase SaaS platform — production, staging, and development environments.
* All customer PHI and operational data processed by Denialbase.
* All Denialbase workforce members (employees, contractors, consultants).
* All subprocessors that may touch Denialbase customer data (see [Subprocessors](/trust/subprocessors)).
* Denialbase corporate systems that support the above (GitHub, GCP, Google Workspace, 1Password).

| ------------- | ----- | --------------------------------------------------------------------------------------- |
| **Yes**       | 53    | Control is fully implemented with evidence                                              |
| **Partial**   | 32    | Control is partially implemented; gaps tracked in [Risk register](/trust/risk-register) |
| **Inherited** | 8     | Control is inherited from GCP; evidence via GCP SOC 2/ISO 27001 reports                 |
| **N/A**       | 4     | Control doesn't apply (remote-only, no physical sites, no outsourced dev)               |

## Exclusions and rationale

<AccordionGroup>
  <Accordion title="A.7.3 — Securing offices, rooms, and facilities">
    Denialbase is a fully remote organization with no physical offices. Workforce security relies on managed workstations, secure home networks, and [AUP — devices](/trust/acceptable-use-policy#devices).
  </Accordion>

  <Accordion title="A.7.6 — Working in secure areas">
    No physical secure areas to protect — see A.7.3 above.
  </Accordion>

  <Accordion title="A.8.23 — Web filtering">
    No corporate network with employee web traffic to filter. DNS-level filtering is considered if workforce expands.
  </Accordion>

  <Accordion title="A.8.30 — Outsourced development">
    All product development is performed by Denialbase employees. No outsourced/offshore development. If this changes, the control will be applicable and tracked.
  </Accordion>
</AccordionGroup>

## Review cadence

* **Monthly** — control implementation status updated by Security Officer.
* **Quarterly** — applicability reviewed with CTO for any scope changes.
* **Annually** — full SoA refresh ahead of external audit; mapped to current version of ISO 27001.
* **Ad-hoc** — any material architecture or vendor change triggers re-evaluation of affected controls.

## How to request the full SoA
