SOC 2 Overview

Type I vs Type II

Aspect	Type I	Type II
Scope	Design of controls at a point in time	Design AND operating effectiveness over a period
Duration	Single date (snapshot)	Observation period (3-12 months, typically 6-12)
Cost	$20K-$60K (first audit)	$40K-$150K (first audit)
Timeline	1-3 months	6-15 months (includes observation period)
Customer Preference	Early-stage acceptable	Enterprise customers require

Start with Type I to validate control design, then transition to Type II within 6 months.

Trust Services Criteria Summary

Category	Focus	Controls
CC1-CC5	Common Criteria (COSO-based)	Control environment, communication, risk, monitoring, control activities
CC6	Logical and Physical Access	Authentication, authorization, physical security, encryption
CC7	System Operations	Vulnerability management, monitoring, incident response, BCP
CC8	Change Management	Authorization, testing, deployment controls
CC9	Risk Mitigation	Vendor management, business disruption, risk transfer
A1	Availability	Capacity planning, DR, recovery testing
PI1	Processing Integrity	Data validation, error handling, reconciliation
C1	Confidentiality	Classification, encryption, disposal
P1	Privacy	Notice, consent, data subject rights, retention

For detailed control requirements per category, see REFERENCE.md.

Clarify First

Before running the readiness assessment, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Report type — Type I (design at a point in time) vs Type II (operating effectiveness over a period) (sets the observation-period requirement and timeline)
• TSC scope — which criteria beyond mandatory Security (Availability, Processing Integrity, Confidentiality, Privacy) (drives which controls and evidence are needed)
• Subservice organizations — carve-out vs inclusive (affects the scope and system description)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the assessment.

Readiness Assessment Workflow

The agent guides organizations through SOC 2 readiness from gap analysis through audit completion.

Workflow: Phase 1 -- Gap Analysis (Weeks 1-4)

1. Define scope -- determine which TSC categories to include (Security is mandatory), define system boundaries, identify subservice organizations (carve-out vs. inclusive), document principal service commitments.
2. Assess current state -- inventory existing policies and procedures, map current controls to TSC requirements, interview process owners and control operators.
3. Run automated gap analysis using scripts/soc2_readiness_checker.py.
4. Document gaps -- missing controls, controls lacking evidence, controls not operating effectively.
5. Prioritize gaps by risk level and remediation effort.
6. Validation checkpoint: Gap analysis covers all in-scope TSC categories; each gap has severity rating and remediation owner assigned.

Workflow: Phase 2 -- Remediation (Weeks 5-16)

1. Develop/update policies -- information security policy, supporting procedures per control domain, policy review and approval workflows.
2. Implement technical controls -- configure IdP with SSO/MFA enforcement, deploy endpoint security (MDM, EDR, disk encryption), implement SIEM logging and monitoring, configure backup and DR, harden cloud infrastructure.
3. Establish processes -- access review procedures, change management workflow, incident response procedures, vendor management program, security awareness training.
4. Set up evidence collection -- configure automated collection, establish repository structure, define refresh cadence per TSC category.
5. Validation checkpoint: All identified gaps remediated; technical controls verified via scripts/soc2_infrastructure_auditor.py; evidence collection producing artifacts.

Workflow: Phase 3 -- Pre-Audit (Weeks 17-20)

1. Conduct internal readiness assessment -- mock audit against all in-scope TSC, validate evidence completeness and quality, run infrastructure auditor for technical validation.
2. Remediate pre-audit findings -- address remaining gaps, strengthen evidence.
3. Select and engage CPA firm -- negotiate scope, timeline, fees; schedule kickoff; prepare system description draft.
4. Validation checkpoint: Mock audit passes with no critical gaps; system description reviewed; auditor engaged.

Workflow: Phase 4 -- Audit Execution

1. Type I audit (if applicable) -- auditor reviews control design; management provides assertions; address findings before Type II.
2. Type II observation period (3-12 months) -- controls operate consistently, evidence collected continuously, quarterly self-assessments, regular auditor check-ins.
3. Fieldwork (2-4 weeks) -- auditor selects samples, tests controls, interviews personnel; draft report review; final report issuance.
4. Validation checkpoint: Clean opinion received; any findings have management response and remediation plan.

Automation Strategies

GRC Platforms: Vanta, Drata, Secureframe, Laika, AuditBoard -- automated evidence collection via API integrations, continuous control monitoring, auditor collaboration portals.

Infrastructure-as-Evidence: Cloud configuration snapshots (AWS Config, Azure Policy, GCP Org Policies), Terraform state as configuration evidence, Git history as change management evidence, CI/CD pipeline logs as deployment control evidence.

Audit Timeline

Typical Timeline (First SOC 2)

Phase	Duration	Activities
Scoping	2-4 weeks	Define TSC, system boundaries, auditor selection
Gap Analysis	2-4 weeks	Assess current controls, identify gaps
Remediation	8-16 weeks	Implement missing controls, policies, procedures
Type I Audit	2-4 weeks	Point-in-time control design assessment
Type II Observation	3-12 months	Controls operate, evidence collected continuously
Type II Fieldwork	2-4 weeks	Auditor testing, evidence review, interviews
Report Issuance	2-4 weeks	Draft review, management response, final report

Annual Renewal

• Begin renewal planning 3 months before observation period ends
• Maintain continuous compliance between audit periods
• Address prior-year findings before new observation period
• Bridge letters available for gaps between reports

Incident Response Requirements

IRP Structure

1. Preparation -- IR team defined, communication channels established, runbooks for common incidents, legal/PR contacts on retainer.
2. Detection and Analysis -- monitoring/alerting coverage, severity classification (SEV1-SEV4), triage procedures, escalation matrix.
3. Containment, Eradication, Recovery -- isolate affected systems, preserve evidence, identify root cause, restore and validate.
4. Post-Incident -- blameless post-mortem within 5 business days, lessons learned, control improvements, notification assessment (MTTD, MTTR, MTTC tracking).

For severity level definitions and breach notification timelines, see REFERENCE.md.

Troubleshooting

Problem	Likely Cause	Resolution
Readiness checker scores are 0% across all categories	Controls JSON missing config_key values or all set to false	Verify the input JSON maps each TSC control to a boolean value under the correct config_key. Run --generate-sample > sample-config.json to see the expected structure.
Infrastructure auditor reports all checks as "fail"	Infrastructure config JSON is empty or uses wrong key names	Run --generate-template to produce a valid template. Populate DNS, TLS, cloud, endpoint, and other sections with actual infrastructure state.
Evidence collector checklist missing categories	--categories flag filtering output	Use --categories all to generate the complete checklist. Available categories: security, availability, processing_integrity, confidentiality, privacy.
Evidence tracker status not updating	Tracker file path incorrect or file not writable	Verify the path passed to --status or --update points to an existing tracker JSON file. Check file permissions.
Cloud mapping not appearing in readiness report	--cloud-mapping flag not included	Add --cloud-mapping to the readiness checker command to include AWS/Azure/GCP control mappings in the output.
Type II observation period too short for auditor	Observation period is less than 3 months	Most CPA firms require a minimum 3-month observation period for Type II. A 6-12 month period carries more weight. Plan the observation window during the scoping phase.
Auditor requests evidence not in the tracker	Evidence catalog does not cover all TSC subcriteria for the selected scope	Supplement the auto-generated checklist with auditor-specific evidence requests. Each CPA firm may have additional requirements beyond the standard TSC evidence items.

Success Criteria

• SOC 2 scope defined with all applicable TSC categories selected, system boundaries documented, and subservice organizations identified (carve-out vs inclusive)
• Gap analysis completed with every identified gap assigned a severity rating, remediation owner, and target completion date
• Readiness score of 80%+ across all in-scope TSC categories before engaging the CPA firm, trending to 95%+ before Type II fieldwork
• Evidence collection framework operational with centralized repository, defined refresh cadence per TSC category, and automated collection where possible
• Infrastructure audit passes with no critical or high-severity findings in DNS, TLS, cloud, endpoint, or access control domains
• Type II observation period of at least 6 months with continuous control operation, quarterly self-assessments, and no significant control failures
• Clean SOC 2 Type II opinion received with any findings addressed by management response and documented remediation plans

---

Scope & Limitations

In Scope:

• SOC 2 Type I and Type II readiness assessment against all TSC categories (CC1-CC9, A1, PI1, C1, P1)
• Infrastructure security validation (DNS, TLS, cloud, endpoint, network, container, CI/CD, secrets)
• Evidence collection framework generation and tracking
• Gap analysis with severity-rated findings and remediation guidance
• Audit timeline planning and CPA firm engagement preparation
• Incident response plan structure and requirements
• Continuous compliance program design

Out of Scope:

• CPA firm audit execution (the tools prepare for audit; the actual Type I/II report requires an independent CPA firm)
• SOC 1 (ICFR) assessment (SOC 1 covers financial reporting controls, not security/availability/privacy)
• SOC 3 report generation (SOC 3 is a public-facing summary derived from SOC 2; it requires a completed SOC 2 audit)
• Penetration testing execution (use infrastructure-compliance-auditor or engage a third-party pentest firm)
• GRC platform selection or implementation (the skill is compatible with Vanta, Drata, Secureframe, etc., but does not implement them)
• Legal advice on customer contractual requirements for SOC 2 reports
• Physical security assessments (the infrastructure auditor covers logical controls; physical data center audits require on-site assessment)

Integration Points

Skill	Integration
infrastructure-compliance-auditor	Provides Vanta-level infrastructure checks across cloud, DNS, TLS, endpoints, access controls, and CI/CD that map directly to SOC 2 TSC requirements
nist-csf-specialist	NIST CSF functions map to SOC 2 TSC categories; use the control mapper to build unified control matrices for organizations pursuing both
information-security-manager-iso27001	ISO 27001 Annex A controls provide a management system backbone that satisfies many SOC 2 requirements; shared evidence reduces audit burden
pci-dss-specialist	PCI DSS requirements overlap with SOC 2 CC6 (access), CC7 (operations), CC8 (change management); shared controls for payment-processing organizations
gdpr-dsgvo-expert	GDPR requirements align with SOC 2 Privacy (P1) criteria; organizations processing EU personal data can leverage shared privacy controls
nis2-directive-specialist	NIS2 minimum security measures overlap with SOC 2 security criteria; EU entities can map shared incident response, access control, and encryption controls
