SOC 2 End-to-End Guide (Big 4 Style)
This guide explains SOC 2 from a Big‑4 auditor perspective, walking through why SOC 2 matters for client trust and deal flow, the Trust Services Criteria (security, availability, processing integrity, confidentiality, privacy), and the differences between Type I (point‑in‑time) and Type II (3–12 months). It outlines a practical SOC 2 engagement lifecycle: scoping/readiness, control design and implementation, documentation, audit testing (tests of design and effectiveness), evidence collection, and final report components (auditor opinion, system description, control matrix, exceptions). The post lists common control failures, example controls and tools (ServiceNow, Jira, Okta, Azure AD, AWS, GCP, Vanta, Drata), and career skills for IT audit/risk professionals. The tone is instructional, emphasizing documentation, consistent evidence, and controls that demonstrably mitigate risk.
Practical, operational guidance on SOC 2 is useful for SaaS and technology vendors (including AdTech/MarTech providers) to demonstrate security and win client trust, but the article is educational rather than a major industry event.

Key Takeaways & Evidence Grounding
- SOC 2 is an AICPA framework based on Trust Services Criteria: Security (mandatory), Availability, Processing Integrity, Confidentiality, and Privacy.
- Type I SOC 2 assesses control design at a point in time; Type II covers control effectiveness over 3–12 months (Type II is preferred by many large firms).
- A typical SOC 2 engagement lifecycle: scoping & readiness assessment → control design & implementation → documentation → audit testing (Test of Design and Test of Effectiveness) → evidence collection → report issuance.
- Final SOC 2 report components include the Independent Auditor’s Report (opinion), System Description, Control Matrix (controls, tests, results), and any Exceptions.
- Common SOC 2 failures: inconsistent evidence across the period, undocumented/manual controls without proof, weak access management, lack of segregation of duties, and policies not followed.

Open-source SOC 2 Evidence Automation Tool
An open-source compliance automation project by Arjav Mehta (posted on DEV on 2026-06-29) provides a customizable agent that connects to AWS via APIs to collect evidence, map items to SOC 2 controls, and generate auditor-ready reports. The tool targets early-stage SaaS/Fintech/Healthtech teams using AWS/GitHub, offers a free pre-audit readiness scan (claims ~2 minutes), supports configurable controls and continuous scanning, and produces verifiable, SHA-256 tamper-evident chains of custody for each evidence item. The project repository is published on GitHub and includes a public checklist for adopters.
Automating SOC2 CC6.6 DNS and Email Evidence
This technical guide explains how SOC2 Trust Services Criterion CC6.6 applies to DNS and email controls and shows how to automate evidence collection so auditors can verify continuity across an audit period. It identifies five specific controls auditors test — DMARC enforcement (p=quarantine/reject), SPF/DKIM coverage for all senders, MTA-STS in enforce mode, DNSSEC validation, and CAA records — and details the evidence auditors require (timestamped records, DMARC RUA reports, continuous logs). The guide warns auditors evaluate control state at the start of the audit window (so p=none during any part of the period is a failure) and emphasizes MFA on all accounts that can modify DNS/email settings. It recommends continuous, timestamped scanning and tamper-evident logs to replace manual, point-in-time evidence assembly.
Investigation: Delve Allegedly Faked SOC 2 Certifications
A Substack investigation alleges that Delve, a compliance automation platform, systematically manufactured false SOC 2 and ISO 27001 certifications by pre-populating audit evidence, generating test procedures internally, and sending finished packages to auditing firms that allegedly rubber-stamped results without independent verification. Named auditors in the report include Accorp, Gradient Certification, Glocert, and DKPC. The report says multiple companies — including venture-backed startups and at least one NASDAQ-listed firm — received these certifications, collectively handling millions of customer records. The article warns that automated compliance can become misleading when evidence is fabricated, and it outlines verification steps for buyers: request full SOC 2 Type II reports under NDA, verify the auditor on the AICPA directory, prefer Type II over Type I, look for exceptions in reports, and evaluate security independently. It also lists other compliance automation vendors (Vanta, Drata, Secureframe, Thoropass) and frames the issue as a systemic trust risk for developer tools.
