SOC 2 Attestation Services
Independent auditors. Defensible outcomes.
Every engagement is scoped, tested, and reviewed by career SOC 2 auditors. We stay independent by design so that your report stands up to procurement, investors, and regulators.

- Chain-of-custody documentation that captures counts, frames, and selection logic.
- Partner and technical review prior to issuance so questions are resolved before the report ships.
SOC 2 Type I Audit

What you receive
- SOC 2 Type I report (Independent Auditor's Report, System Description review, Management's Assertion)
- Control matrix with test procedures and results
- Exceptions documented with objective rationale
- Complementary user entity controls (CUECs) clearly enumerated
Best for: Teams needing a defensible attestation on design to unlock enterprise deals or investor diligence.

We do not provide readiness assessments, remediation guidance, or control design consulting. If you require advisory work, we will gladly collaborate with your chosen advisor. Our role remains strictly independent.
What makes a SOC 2 report “defensible”?
Defensibility comes from disciplined execution and complete documentation. Our approach is transparent and testable:
- Scope discipline: Criteria selection, subservice carve-outs, and system boundaries are documented and justified.
- Sampling you can explain: Statistically sound or risk-based sampling with counts, frames, and selection logic captured in workpapers.
- Evidence integrity: Time-bound evidence requests, metadata preservation, and verifiable screen capture/exports with hash or provenance notes when applicable.
- Traceable procedures: Each control maps to a procedure, evidence item(s), and a tester's conclusion. No gaps, no hand-waving.
- Quality review: Independent technical and partner review prior to issuance, with queries resolved and logged.
- Exception precision: Clear description, impact, and criteria reference. Never vague language that invites second-guessing.

Defensibility in the real world
Anonymized client
DevTools Scale-Up (Type II)
Procurement raised three exception challenges. Our report's sampling logic, evidence chain, and exception rationale resolved all challenges in one review cycle, enabling an annual vendor agreement.
Anonymized client
Healthcare SaaS (Type I)
Investor diligence required a point-in-time opinion within 30 days. We executed a tightly scoped Type I with explicit CUECs and subservice disclosures, and the deal closed on schedule.
Anonymized client
Fintech API (Type II)
Legal requested clarity on carve-outs. Our report included explicit carve-out language and matrix cross-references. Questions closed without rework.

FAQ
Do you do readiness?
No. We are an independent audit firm and do not provide readiness or remediation services.
Can you tell us how to fix exceptions?
We document exceptions precisely and fairly. Because we maintain independence, we do not design controls or provide remediation advice.
What is included in a Type I vs. Type II?
Type I opines on control design at a point in time. Type II opines on operating effectiveness over a review period. Both include a defensible report package with clear scope, CUECs, and disclosures.
