Private beta · invite only · SOC 2 and ISO 27001

A workspace for audit firms. Request list to signed report.

Tiomsu runs a SOC 2 or ISO 27001 engagement end to end — requests, samples, tests, review, findings, report and binder — with every result traced to a test, a sign-off and a document. No spreadsheet. No Word assembly.

We onboard a few firms at a time and reply personally.

Illustration. The real thing is in beta.

§ 01 · How it works

Built around how an audit actually runs.

Evidence lives in requests, not controls. Samples are drawn, confirmed and sent. Review is a signature on a version. The report is generated from the records, never typed over.

01

Requests, not controls

One request links to many controls, so HR sends one leaver list instead of answering six people. Each request has a kind — population, sample or document — a title, a detailed description, an owner and a due date. Merge or split them to match what the client can actually provide.

02

Samples that stay reproducible

Your sample-size table by control frequency. Tiomsu suggests a size, draws items at random with a stored seed, and the preparer confirms or overrides with a reason. The exact items go to the client as a sample request linked to its population — and never roll forward to next year.

03

Review that means something

Every sign-off records who, when, and which version of the record it covers. An edit after sign-off clears it. Nobody reviews their own work, and the report cannot be approved while a required checklist step is unsigned.

04

Report and binder from the records

Your DOCX templates, letterhead, opinion variant and boilerplate. Regenerate after a change and read the diff; an approved report is immutable. The binder is a ZIP of every document, test and sign-off, with a manifest.

§ 02 · Connections

Clients answer where they already work.

A request goes out from the engagement; the answer comes back as a pinned copy — file, digest, version, collection date, submitter. Where the client answers from is up to them.

Available

From their compliance platform

Clients who run their program in AuditBadger see your requests in an auditor inbox there and answer without a second login. A client admin approves the connection — one account, one project, one period — and can revoke it at any time. Obsolete evidence is labelled, never hidden.

On request

From the platform they use instead

If several of your clients live on another compliance platform, tell us which one. The connector is a small, well-defined contract and we would rather build the next one with a firm that needs it. Platform teams who want their customers' auditors in Tiomsu: same door.

Available

From a small portal

Everyone else gets a deliberately small portal: their requests, the exact sample items, last period's answer, upload and comments. Works on a phone. It is not a GRC tool and does not try to be.

Your tests, notes and findings never leave Tiomsu — only what you deliberately share for a client response.

§ 03 · The model

Nine objects. Fixed on purpose.

Fixed objects, fixed fields, fixed lifecycles. You change wording, templates and your own checklist steps — never the data model. No form builder, no custom columns, nothing to configure before the first engagement.

Engagement
Client, framework and version, report type or audit purpose, period or as-of date, team, report template. Status is derived from the records, never set by hand.
Checklist
Our program per profile, plus the steps your firm adds. Each step carries a preparer and a reviewer sign-off.
Criteria
Read-only catalogs: TSC 2017 with 2022 points of focus; ISO 27001:2022 clauses and Annex A. An engagement pins one version for good.
Controls
Imported from AuditBadger, from CSV, or picked from your standard set by the readiness questionnaire. Every in-scope criterion shows its controls or a visible gap.
Requests
Population, sample or document. Open, submitted, returned, accepted. Every submission and comment kept; last period's accepted answer one step away.
Tests
One per control per engagement. Inquiry, observation, inspection, reperformance. Linked to accepted submissions; a Type 2 test without a sample cannot be signed.
Findings
Raised from a test. Exception or nonconformity grade, client response, follow-up. Every finding reaches the report; none can be deleted after the report is shared.
Description
Structured sections with prompts for what an auditor needs. The client drafts; you accept each change. The report shows only accepted text.
Report & binder
DOCX and PDF from your templates, chosen per scenario. A ZIP of every document, test and sign-off, with a manifest.

SOC 2 Type 1 and Type 2 first. ISO 27001:2022 follows during the beta.

§ 04 · Private beta

Shadow-run one engagement with us.

We're inviting a small number of firms to run one SOC 2 Type 2 engagement in Tiomsu alongside their current tool. Same client, same period, no risk to the issuance. At the end you tell us where it saved time — requests, testing, review, report — and what got in the way.

What you get
  • A firm account with MFA for your whole team
  • Our engagement program and standard request list, to adapt
  • Your report templates loaded as DOCX scenarios
  • A direct line to the people building it
  • A binder export that is yours to keep, whatever happens next
What we ask
  • 1One real SOC 2 Type 2 engagement, run in parallel
  • 2A candid read on each stage: what was faster, what was in the way
  • 3An hour of your time every couple of weeks
