SOC 2 Control Matrix Template for Startups: Map Work to Proof

A SOC 2 control matrix is a working map from the criteria in your proposed report to the controls your team actually runs. For each control, record its scope, owner, procedure, timing, source system, expected proof, and current status. Build it after you define the service and design the controls. A downloaded list of generic safeguards cannot tell you whether your system uses those safeguards or whether they cover the right people and data.

What goes in a SOC 2 control matrix template?

The AICPA Trust Services Criteria are criteria for evaluating controls over Security, Availability, Processing Integrity, Confidentiality, and Privacy. They are not a prescribed set of company procedures or a spreadsheet format. Management defines controls for the service in scope, its risks, and its commitments, then discusses the proposed report with the CPA firm.

Use these fields as a starting worksheet:

Field	What to record
Criterion	The applicable criterion ID and category, with a link to the current source
Control ID and outcome	A stable ID and the result the activity is meant to achieve
Scope	The service, systems, accounts, people, or data the control covers
Activity and procedure	What the owner does and where the approved steps live
Owner and reviewer	Who operates the control and who checks the result when review is required
Timing	The schedule or event that starts the work and its due rule
Source and expected proof	The authoritative system, safe locator, and record that should exist after real operation
State and date	Proposed, implemented, operating, or blocked, with the date and basis for that assessment
Gap and next action	What is missing, who will fix it, and when to recheck

Keep a criterion-to-control mapping separate from the control record if one activity supports several criteria. That lets you change one procedure without copying edits across many rows. One criterion can also need several controls. Neither relationship gives you a universal target count.

What does a copyable matrix row look like?

Suppose your team grants and removes production access through an identity provider. AICPA criterion CC6.2 addresses authorizing users before granting credentials and removing access when it is no longer authorized. Copy this CSV header and illustrative row into a sheet, then replace each field with your own facts:

criterion,control_id,outcome,scope,activity_procedure,owner,reviewer,trigger,due_rule,source_proof,status,status_date,gap_next_action,gap_owner,recheck_date
CC6.2,AC-01,"Access starts after approval and ends when no longer authorized","Production identity groups and governed systems","Approve requests before provisioning; remove access after departures",Identity owner,Service owner,"Each access request or departure","Before provision or within the approved departure window","Safe links to approval and removal records in approved systems",Proposed,YYYY-MM-DD,"Check procedure and source access",Engineering lead,YYYY-MM-DD

The dates and due rule are placeholders for your own approved schedule. Move the row from proposed to implemented only after management checks the actual scope, owner, procedure, and usable source. Mark it operating only after a real due occurrence has a dated record. If one control maps to another criterion, add a mapping rather than creating a second, diverging copy of its procedure.

This is an illustration, not an AICPA control requirement. A SaaS team with support tools, contractors, or separate cloud roles would need to test whether those paths belong in the control scope. The controls guide explains how to design the activity; the gap analysis guide helps record what is missing before relying on a candidate Type 2 period.

How do you keep the matrix current?

Review a row when a control owner, service boundary, procedure, source system, or customer commitment changes. Do not change a status to operating because a policy was approved or a test run succeeded. Check a real occurrence and its dated record. During a Type 2 period, preserve the prior control version and the date of each change so management can explain what operated when.

Before sharing the matrix with a CPA firm, reconcile its criteria and scope with the agreed engagement, then trace requested evidence to the source. A matrix is an index for management, not a substitute for the complete populations, operating records, or the CPA firm’s procedures. The Type 2 populations guide explains how to define a complete source set when sampling applies.

FileGRC can hold the proposed criteria, controls, owners, source components, and safe evidence references in a Git-native GRC workspace. JSON holds structured records, Markdown holds long-form work, and Git supplies the change history. Starter records are proposals, not compliance claims. Keep restricted exports in their source systems or approved stores. Your team operates the controls, and the CPA firm examines them and decides whether evidence is sufficient.
