Who can do a SOC 2 audit?

Only an independent, licensed Certified Public Accountant (CPA) firm in good standing with its state board of accountancy and enrolled in the AICPA Peer Review Program can perform a SOC 2 audit and issue a valid attestation report. Non-CPA cybersecurity consultants, automated compliance software platforms, and internal security teams cannot legally sign or issue a SOC 2 report.

How to prepare for a SOC 2 audit?

To prepare for a SOC 2 audit: (1) Define your audit scope by selecting the applicable Trust Services Criteria (Security is mandatory); (2) Conduct an initial readiness gap assessment against the 47 AICPA criteria; (3) Author and approve required organizational security policies; (4) Implement necessary technical safeguards such as MFA, data encryption, and role-based access control; and (5) Collect point-in-time configuration evidence and system architecture descriptions for auditor review.

How long does a SOC 2 audit take?

A SOC 2 Type 1 audit typically requires 4 to 8 weeks from initial readiness preparation to final report delivery. The internal readiness remediation and evidence assembly phase generally takes 2 to 4 weeks, while independent CPA auditor fieldwork, walkthrough interviews, and report drafting require an additional 2 to 4 weeks.

How much do SOC 2 audits cost?

Direct CPA audit fees for a SOC 2 Type 1 examination generally range from $12,000 to $25,000 for the Security criterion when engaging a boutique or tech-specialized accounting firm. Total first-year expenses—including optional compliance automation software ($6,000–$15,000), external penetration testing ($4,000–$10,000), and internal engineering hours—typically total between $22,000 and $50,000.

Are SOC 2 audits required?

SOC 2 audits are not a government or statutory legal requirement. However, they are practically mandatory for B2B technology and SaaS companies selling to enterprise customers. Enterprise procurement teams, vendor security reviewers, and corporate risk officers routinely mandate a verified SOC 2 report as a contractual prerequisite before deploying software that touches corporate or customer data.

SOC 2 Type 1 Audit: What Happens, How Long It Takes, What It Costs

Q: What is a SOC 2 Type 1 audit?

A SOC 2 Type 1 audit is an independent attestation examination performed by a licensed Certified Public Accountant (CPA) firm under AICPA SSAE 18 standards (AT-C Section 205). The audit evaluates whether a service organization has suitably designed internal controls to meet the applicable Trust Services Criteria as of a specific calendar date (a point in time). Unlike Type 2, it does not evaluate operational effectiveness over a historical observation window.

What Is a SOC 2 Type 1 Audit?

A soc 2 type 1 audit is an independent attestation examination conducted by a licensed Certified Public Accountant (CPA) firm under AICPA SSAE 18 standards (codified in AT-C Section 205). The audit evaluates the suitability of the design of an organization's internal controls as of a single calendar day—referred to under professional standards as a "point in time." The examination assesses whether management has formally described its technology infrastructure, defined governance policies, and implemented security safeguards capable of satisfying the applicable AICPA Trust Services Criteria if operated as designed.

Unlike informal vendor risk questionnaires, self-attestations, or automated code vulnerability scans, a SOC 2 Type 1 examination produces a formal, legally recognized attestation deliverable: the Independent Service Auditor’s Report. Within this document, an accredited accounting firm issues an official professional opinion verifying that your system description fairly represents your operational architecture and that your documented controls are properly designed to mitigate cybersecurity risks.

The defining characteristic of a Type 1 examination is its strict temporal scope. The CPA firm tests your security environment as it exists on a specific target date (for example, "as of October 31, 2026"). The auditor does not review whether your development team conducted code reviews across the preceding six months, nor do they verify whether access was revoked within 24 hours for every employee who departed last quarter. Instead, the auditor verifies that the control structure exists, is documented, and is technically configured on that chosen assessment date.

AICPA Attestation Legal Framework: A SOC 2 examination is an attestation engagement governed by the American Institute of Certified Public Accountants (AICPA). Only a licensed, independent CPA firm in good standing can perform the examination and sign the auditor’s opinion. Automated compliance software platforms, penetration testing vendors, and cybersecurity consultancies cannot legally issue a SOC 2 report. SOC 2 Gap provides free, independent technical readiness tools and educational guidance, but does not conduct commercial audits or issue attestation opinions.

The SOC 2 Type 1 Audit Process: Step-by-Step Fieldwork

Navigating the soc 2 type 1 audit process requires understanding the sequential phases of an attestation engagement. While enterprise software vendors often perceive the audit as an opaque hurdle, the examination follows a structured, repeatable methodology established under professional attestation standards:

1

Criteria Scoping and System Boundary Definition

The audit commences by defining the exact organizational and technological boundaries of the system under examination. You and your auditor determine which Trust Services Criteria apply to your service offering. The Security criterion (Common Criteria CC1–CC9, comprising 22 controls) is mandatory for 100% of SOC 2 audits. You must determine whether to include additional modular criteria: Availability (if contractual uptime SLAs are committed to clients), Confidentiality (if handling proprietary client IP or sensitive data), Processing Integrity (if performing complex financial or transactional processing), or Privacy (if storing personal identifiable information).

2

Readiness Gap Assessment and Control Implementation

Before engaging the CPA firm for formal fieldwork, management must benchmark current controls against the AICPA criteria. Organizations identify operational gaps, such as unencrypted local drives, lack of centralized identity management, missing background checks, or absent vendor review policies. Remediating these gaps involves drafting governance policies, configuring cloud security settings, and establishing formal procedures. You can benchmark your posture using our free, in-browser SOC 2 readiness assessment and cross-reference your controls against our interactive SOC 2 checklist.

3

Evidence Collection and Artifact Assembly

Because a Type 1 audit evaluates design as of a single calendar day, evidence collection focuses on proving that controls exist and are configured as of that date. In auditing terminology, the required sample size for design-only controls is typically a "sample size of 1." For example, instead of providing 40 separate pull request approvals spanning six months, you provide evidence of current repository branch protection rules, the current configuration enforcing mandatory multi-factor authentication (MFA) across your identity provider, and a sample ticket demonstrating a recent change review.

4

CPA Auditor Fieldwork and Walkthrough Interviews

During fieldwork, the CPA firm conducts technical walkthroughs with key system operators, including engineering leads, DevOps personnel, and HR administrators. The auditor inspects cloud console configurations (e.g., AWS, GCP, or Azure), verifies identity provider enforcement, reviews the network architecture topology, and validates human resource records. The auditor performs three standard test procedures: inquiry (interviewing personnel regarding policy execution), observation (watching an engineer demonstrate system behavior), and inspection (reviewing system-generated configuration logs, screenshots, and policy documents).

5

System Description Drafting and Management Assertion

Management prepares the formal "Description of the System" (Section III of the final report), detailing the infrastructure, software components, people, data flows, and control procedures governing the service. Management also signs Section II, the formal "Management Assertion," legally certifying that the description fairly presents the system and that controls were suitably designed as of the specified date.

6

Quality Review and Independent Auditor Report Issuance

The engagement team submits its workpapers to an independent quality review partner within the CPA firm. Once technical quality checks pass, the firm signs Section I—the Independent Service Auditor's Report—issuing a formal opinion (typically an Unqualified opinion) and delivering the bound digital PDF report.

How Long Does a SOC 2 Type 1 Audit Take?

A common operational question founders ask is: how long does a soc 2 type 1 audit take from kickoff to signed report? For modern cloud-native B2B SaaS startups, the complete timeline spans between 4 and 8 weeks. Because the examination tests controls at a single point in time, there is no mandatory multi-month historical observation period.

The elapsed duration depends primarily on two factors: the organization's existing security hygiene before audit kickoff, and the responsiveness of internal engineering personnel when fulfilling auditor artifact requests. The schedule below details the standard 8-week delivery cadence:

Audit Phase	Duration	Key Activities and Deliverables	Primary Ownership
Phase 1: Scoping & Engagement	Week 1	Select criteria, define production system boundaries, execute CPA engagement letter, and configure evidence repository or compliance tooling.	Executive Leadership & Lead Auditor
Phase 2: Gap Remediation	Weeks 2–3	Enact 15–20 essential security policies (access control, incident response, data retention); enforce MFA, SSO, and full-disk encryption; conduct vendor reviews.	DevOps, Security & HR Teams
Phase 3: Evidence Assembly	Week 4	Gather point-in-time configuration snapshots, export user rosters, collect external penetration test results, and assemble the system architecture diagram.	Technical Lead & Compliance Admin
Phase 4: Auditor Fieldwork	Weeks 5–6	Participate in 3 to 5 virtual walkthrough sessions with the CPA firm; provide clarifications; remediate any noted configuration deficiencies in real time.	CPA Audit Team & Engineering Leads
Phase 5: System Description & Reporting	Weeks 7–8	Draft and review Section III (System Description); sign management assertion letter; complete partner quality review; receive final bound report.	CPA Signing Partner & CEO/CTO

Factors That Accelerate or Delay the Timeline

Organizations can compress this schedule to 4 weeks if they meet three conditions: (1) They use modern infrastructure-as-code (e.g., Terraform on AWS) with centralized single sign-on already deployed; (2) They complete an external network and application penetration test prior to audit launch; and (3) A dedicated technical lead is assigned to respond to auditor inquiries within 24 hours. Conversely, audits extend beyond 8 weeks when organizations operate fragmented legacy environments, lack formal change control records, or experience prolonged delays in drafting the system description.

SOC 2 Type 1 Audit Cost Breakdown

Estimating your total soc 2 type 1 audit cost requires separating direct CPA audit fees from secondary expenses such as penetration testing, compliance tooling, and internal engineering allocation. While direct audit fees represent the contractual line item paid to the accounting firm, auxiliary compliance investments represent a significant portion of first-year outlays.

Expense Category	Typical Cost Range	Cost Factors & Description	Mandatory vs. Optional
Independent CPA Audit Fees	$12,000 – $25,000	Direct attestation fees paid to a licensed CPA firm for Security criteria. Varies based on firm tier (boutique vs. regional vs. Big Four) and system complexity.	Mandatory (Required for attestation)
External Penetration Testing	$4,000 – $10,000	Independent third-party network and web application penetration test. Required by auditors to fulfill CC4.1 and CC7.1 testing criteria.	Mandatory under auditor evidence standards
Compliance Automation Software	$6,000 – $15,000	API-based platforms (e.g., Vanta, Drata, Secureframe) that continuously monitor cloud configurations and automate artifact collection.	Optional (Reduces engineering hours by ~60%)
Employee Background Checks	$500 – $2,000	Pre-employment criminal and identity verification through vendors like Checkr. Budget roughly $40 to $80 per current employee.	Mandatory for CC1.4 workforce controls
Internal Engineering Labor	100 – 180 hours (~$10,000 equiv.)	DevOps and engineering time spent writing Terraform scripts, configuring SSO/MFA, writing policies, and attending walkthroughs.	Mandatory internal operational overhead
Total First-Year Type 1 Investment	$22,500 – $52,000	Comprehensive budget for a seed or Series A tech startup achieving its first SOC 2 Type 1 report.	All inclusive investment range

When selecting an accounting firm, tech startups generally achieve the best balance of speed, modern tooling compatibility, and cost efficiency by working with tech-specialized boutique CPA firms.

The SOC 2 Type 1 Audit Checklist: Essential Control Domains

Preparing for point-in-time fieldwork is significantly streamlined by organizing controls into functional operational buckets. A practical soc 2 type 1 audit checklist focuses on six core domains that satisfy the AICPA Common Criteria:

1. Identity & Access Governance (CC6.1–CC6.3)

Hardware or authenticator-app Multi-Factor Authentication (MFA) enforced on all corporate systems (Google Workspace/Okta, AWS, GitHub).
Role-Based Access Control (RBAC) configured according to the Principle of Least Privilege.
Password manager deployment with mandatory 16+ character complexity rules.
Centralized Single Sign-On (SSO) integration across production and administrative platforms.

2. Cloud Infrastructure & Encryption (CC6.6–CC6.8)

All production databases, object storage buckets (e.g., S3), and virtual block volumes encrypted at rest using AES-256 or KMS.
Encryption in transit enforced via TLS 1.2 or TLS 1.3 across all public and internal service boundaries.
Production VPC networks isolated from staging, testing, and corporate internal networks with strict security group egress rules.
Automated cloud secrets management (AWS Secrets Manager, HashiCorp Vault) with no hardcoded credentials in source code.

3. Software Development & Change Management (CC8.1)

Mandatory peer code reviews enforced via branch protection rules on `main` and `production` branches.
Automated CI/CD security checks, including static application security testing (SAST) and dependency vulnerability scanners.
Separation of duties: software engineers prevented from directly committing code to production without peer pull request approval.
Documented release management procedures with rollback plans for major deployments.

4. People Operations & Governance (CC1.1–CC1.5)

Written and approved suite of core security policies (Information Security, Access Control, Incident Response, BC/DR).
Pre-employment background verification completed for all new personnel prior to granting system access.
Documented employee acknowledgment of Code of Conduct and Acceptable Use policies upon hire.
Annual security awareness and anti-phishing training curriculum completed by all staff members.

5. Vulnerability & Threat Management (CC7.1–CC7.4)

Annual third-party external penetration test executed by an accredited cybersecurity firm.
Continuous automated vulnerability scanning enabled across production cloud infrastructure and container registries.
Documented vulnerability remediation SLAs (e.g., Critical flaws patched within 7 days, High within 30 days).
Centralized audit logging enabled across cloud platforms (e.g., AWS CloudTrail) with tamper-resistant log retention.

6. Vendor Risk & Business Continuity (CC9.1–CC9.2)

Documented inventory of all third-party subservice organizations and critical SaaS vendors.
Annual collection and review of third-party SOC 2 Type 2 reports (e.g., AWS, GCP, Stripe, Datadog).
Tested Business Continuity and Disaster Recovery (BC/DR) plan, including documented data backup restoration tests.
Formal Incident Response plan with defined severity levels, escalation trees, and customer notification protocols.

What a SOC 2 Type 1 Report Contains (and What It Does Not Prove)

Receiving your final deliverable from the CPA firm gives your sales team an essential enterprise asset. To leverage the document effectively in security reviews and RFPs, you must understand both its formal anatomy and its commercial boundaries.

The Four Standard Sections of a Type 1 Report

Section I: Independent Service Auditor’s Report: Written and signed by the independent CPA firm. Contains the auditor’s formal opinion stating whether the system description is fairly presented and whether management's controls were suitably designed as of the specified test date to meet the AICPA Trust Services Criteria.
Section II: Management Assertion: A legally binding written statement signed by corporate officers (typically the CEO or CTO). Management asserts responsibility for designing, implementing, and maintaining effective controls, and affirms that the system description accurately reflects reality.
Section III: Description of the System: The comprehensive technical narrative authored by the company. Details the services provided, technical infrastructure, system boundaries, software applications, personnel responsibilities, data flows, and subservice organization dependencies (e.g., cloud hosting providers).
Section IV: Applicable Criteria, Related Controls, and Tests of Controls: The detailed matrix mapping each AICPA Trust Services Criterion to the company's specific control activities. In a Type 1 report, this section describes the design of each control and indicates the auditor's test procedure (e.g., inquiry, inspection, or observation).

What a Type 1 Report Proves

A Type 1 report conclusively proves to external stakeholders that your company has instituted formal, institutional-grade security architecture. It proves that an accredited third-party accounting firm examined your policies, inspected your cloud configurations, reviewed your employee controls, and confirmed that your technical safeguards are suitably designed to protect client data. For seed and early Series A startups, this proof often suffices to unblock enterprise pilot contracts and satisfy initial vendor procurement questionnaires.

What a Type 1 Report Does NOT Prove

It is equally critical to understand what a Type 1 report does not prove. A Type 1 report provides zero assurance regarding operational effectiveness over time. It does not prove that an employee followed security policies yesterday, nor does it prove that systems will remain secure tomorrow.

For example, an auditor conducting a Type 1 examination as of October 31 verifies that production databases are encrypted on October 31. The auditor does not test whether an unencrypted backup was inadvertently left exposed on an open network in August. Similarly, the auditor verifies that access revocation policies exist, but does not pull employee termination logs from March to verify whether credentials were systematically revoked within the required 24-hour SLA.

Because of these inherent limitations, enterprise procurement teams, corporate risk committees, and Fortune 500 CISOs view a Type 1 report as an interim milestone. In enterprise contracts, buyers frequently insert compliance covenants stipulating that the vendor must complete and deliver an annual SOC 2 Type 2 report within 6 to 12 months. For a comprehensive comparison of how buyer expectations differ between report tiers, consult our detailed analysis on SOC 2 Type 1 vs. Type 2 requirements.

Strategic Playbook: When to Pursue Type 1 vs. Skipping to Type 2

Deciding whether to execute a Type 1 audit or proceed directly to a Type 2 examination is a pivotal strategic decision for executive leadership. While skipping Type 1 saves upfront auditor fees, it introduces operational risks. Use the decision matrix below to determine the optimal path for your organization:

Company Context & Stage	Recommended Strategy	Strategic Rationale
Seed / Early Series A with Urgent Pipeline	Pursue SOC 2 Type 1 Immediately	Unblocks active enterprise procurement deals in 4 to 8 weeks. Provides immediate validation while establishing the baseline date for your subsequent Type 2 observation window.
Bootstrapped or Capital-Constrained Startup	Pursue Type 1 as Milestone	Lower initial CPA audit fees ($12k–$25k vs. $25k–$50k+). Allows the team to debug control processes before committing to a high-stakes multi-month sampling window.
Growth Stage Selling to Fortune 500 / FinTech	Skip Directly to Type 2	Enterprise procurement teams in regulated sectors frequently reject Type 1 reports. Commencing an immediate 3- or 6-month Type 2 observation window avoids redundant testing fees.
Company with Mature Existing Controls	Skip Directly to Type 2	If your team has enforced MFA, PR reviews, background checks, and logging for over 6 months, you already possess the historical population records required for Type 2 sampling.

Regardless of which path you choose, establishing technical readiness before contacting audit firms prevents expensive scope creep and wasted billable hours. Begin by benchmarking your current infrastructure against the 47 AICPA criteria using our zero-signup in-browser SOC 2 readiness tool.
