What is the primary objective of SOC 2?

The primary objective of SOC 2 is to provide independent attestation that a service organization's controls meet the Trust Services Criteria (TSC) for security, availability, processing integrity, confidentiality, and privacy. Developed by the AICPA, SOC 2 evaluates systems handling customer data, with Security (CC1-CC9) mandatory. Type 2 reports assess design and operating effectiveness over 3-12 months, delivering assurance to stakeholders via CPA audits.

Who is legally or professionally required to comply with SOC 2?

No organization is legally required to comply with SOC 2, as it is a voluntary AICPA framework; however, service organizations like SaaS, cloud, and data processors face professional mandates from enterprise clients. Targeted at providers storing, processing, or transmitting customer data, it's essential for vendor risk assessments, RFPs, and MSAs where 70-80% of deals demand Type 2 reports.

Oes SOC 2 require an external audit or third-party certification?

Yes, SOC 2 requires an external audit by an independent AICPA-accredited CPA firm to issue Type 1 or Type 2 reports. Type 1 verifies control design at a point in time; Type 2 tests operating effectiveness over a period, including evidence sampling like logs and penetration tests. No formal certification exists—reports provide the attestation.

How often should an assessment for SOC 2 be performed?

SOC 2 Type 2 assessments should be performed annually to capture a full monitoring period of 3-12 months. Bridge letters from management extend validity up to 3 months between audits, confirming no material changes. Continuous monitoring ensures ongoing evidence for recertification.

What are the consequences of non-compliance with SOC 2?

Non-compliance with client-mandated SOC 2 results in deal disqualification, extended sales cycles (3-6 months), and heightened breach liability exceeding $1M per incident. No AICPA fines apply, but operational risks include lost revenue, reputational damage, and custom contract clauses inflating CAC by 20-50%.

An SOC 2 be mapped to other international frameworks?

Yes, SOC 2 maps effectively to frameworks like ISO 27001 (80% control overlap), NIST CSF, and others via AICPA spreadsheets. Common Criteria (CC1-CC9) align with ISO Annex A and NIST categories, enabling multi-compliance efficiency without dual audits, particularly for Security controls.

What is the first step to begin implementing SOC 2?

The first step to implement SOC 2 is a scoping exercise and gap analysis against the Trust Services Criteria, engaging a CPA for readiness assessment. Define in-scope systems, data flows, and TSC (Security mandatory), inventory assets, and prioritize 50-100 controls like IAM and logging using tools like Vanta.

What is the primary objective of AS9110C?

AS9110C's primary objective is to define quality management system requirements for aviation maintenance, repair, and overhaul (MRO) organizations to ensure consistent conformity of products and services to customer and regulatory requirements. It builds on ISO 9001:2015 using the High Level Structure (HLS), embedding aerospace-specific controls for configuration management, counterfeit parts prevention, human factors, maintenance release, and risk-based thinking (RBT) across Clauses 4–10 to support continuing airworthiness and supply-chain readiness via IAQG OASIS listing.

Who is legally or professionally required to comply with AS9110C?

AS9110C applies to MRO organizations providing maintenance, repair, overhaul, or continuing airworthiness services for commercial, private, and military aircraft. Target entities include independent repair stations, airline maintenance departments, component overhaul facilities, and OEM MRO divisions; compliance is professionally required by customers, OEMs, and regulators (e.g., FAA/EASA Part-145 alignments) for contract eligibility and OASIS approval, with no employee/revenue thresholds specified.

Does AS9110C require an external audit or third-party certification?

Yes, AS9110C requires third-party certification through accredited registrars following a two-stage external audit process. Stage 1 reviews documentation and readiness; Stage 2 verifies effective QMS implementation via on-site evidence of operational cycles, internal audits, and management review (with at least three months of data). Certification is listed on IAQG OASIS, with surveillance audits annually and recertification every three years.

How often should an assessment for AS9110C be performed?

Internal audits for AS9110C must be performed at planned intervals based on process risk, with critical maintenance processes (e.g., configuration control, release-to-service) audited more frequently. Management reviews occur regularly, tied to business cycles with sufficient data; full internal audit cycles and one management review (after 3+ months of QMS operation) are prerequisites before external certification, followed by annual surveillance.

What are the consequences of non-compliance with AS9110C?

Non-compliance with AS9110C risks regulatory sanctions, contract loss, and operational shutdowns in safety-critical MRO environments. Consequences include FAA/EASA Part-145 certificate suspension, fines up to $100k/day, liquidated damages from airline contracts, litigation from airworthiness failures, and exclusion from OEM bids/OASIS, potentially causing multimillion-dollar revenue losses and reputational damage.

An AS9110C be mapped to other international frameworks?

Yes, AS9110C uses ISO 9001:2015's HLS (Annex SL) for seamless mapping to aligned frameworks via shared Clauses 4–10 structure. IAQG provides correlation matrices linking AS9110C to regulatory requirements (e.g., EASA/FAA Part-145), enabling integrated QMS without duplication while prioritizing statutory/regulatory overrides.

What is the first step to begin implementing AS9110C?

The first step for AS9110C implementation is a disciplined gap analysis mapping existing processes to all clauses using IAQG checklists. Conduct evidence-based review (desk audit plus process observations), prioritize high-risk gaps (e.g., counterfeit prevention, RBT per Clauses 6.1/8.1.1), define QMS scope with regulatory mapping, and produce a phased SOW with executive sponsorship.
