SOX Program Cost

01

Median mid-market SOX program consumes 2,400–3,800 total testing hours per year.

For 300–1,500 emp companies, the hour distribution runs internal audit 55–65 percent, management testing 15–20 percent, outsourced consulting 10–20 percent, remediation 5–10 percent. A 650-emp PE portco with 120 controls typically consumes 2,800–4,200 hours at traditional manual testing.

Mid-market control population benchmarks: 300–500 emp median 55–90 controls; 500–1,000 emp median 90–150; 1,000–1,500 emp median 150–220.

ITGC sub-population typically represents 65–75 percent of total control count at mid-market scale. Multi-entity roll-ups multiply the base with ~25 percent overlap reduction. Industry-specific scope expansions: healthcare adds 15–40 HIPAA-overlap controls, defense contractor adds 40–110 CMMC 2.0 Level 2 controls, EU-exposed finance adds 30–80 DORA controls.

03

Outsourced SOX consulting for readiness at 300–1,500 emp companies runs $250,000–$500,000 per year.

Pre-IPO readiness engagements run $300,000–$600,000 plus execution-phase engagements continuing at $200,000–$400,000. Outsourced consulting produces external deliverables (walkthrough memos, control matrices, test workpapers) without leaving in-house evidence capability, restarting the cost clock at the next testing cycle.

04

SOX + SOC 2 evidence consolidation saves 1,300–1,800 hours per year at 650-emp scale.

Running SOX ITGC plus SOC 2 separately typically consumes 3,400–5,200 total hours/year with ~65 percent testing-work overlap. Consolidated evidence stream with framework-tag mappings reduces total hours to 2,100–3,400. Multi-framework overlap (SOX + SOC 2 + DORA + CMMC 2.0 + ISO 42001) saves 2,000–3,500 hours/year at same scale.

AuditBoard & Competitive Landscape

01

AuditBoard was acquired by Hg for $4.4 billion in 2024.

The acquisition, announced May 2024, represented the largest GRC/SOX platform exit to date and validated the category at enterprise scale. AuditBoard's pre-acquisition customer base was weighted toward 2,000+ emp enterprise with deep SOX 404(b) programs.

02

AuditBoard mid-market ACV for 300–1,500 emp customers in 2026 lands $150,000–$250,000 per year.

Enterprise deployments range $250,000–$500,000+. Customer reports on r/Accounting, portco CFO forums, and published G2 reviews consistently place the mid-market quote band, with ~20–30 percent feature utilization at the 400–900 emp scale driving the downmarket mispricing argument.

03

Prova ACV at 300–1,500 emp is $12,000–$60,000 per year per entity.

Department-head tier priced at $1,000–$5,000 per month per entity. Typical microcap cost reduction vs AuditBoard: 70–90 percent year-over-year, holding evidence quality constant or improving it. A 650-emp PE portco replacing $200K AuditBoard with $40K Prova returns $160K to G&A.

Internal Audit Staffing

01

Traditional internal audit staffing benchmark: 1 FTE per 40–60 controls under manual testing.

The IIA Pulse of Internal Audit and Protiviti Internal Audit Capabilities Report data place median IA headcount at 2 FTE for mid-market companies (sub-$1B revenue) with an interquartile range of 1–4. PE-backed portcos skew toward the lower end due to sponsor margin pressure.

Source: IIA Pulse of Internal Audit 2025; Protiviti Internal Audit Capabilities Report 2024–2025

02

Agent-augmented internal audit ratio: 1 FTE per 80–120 controls with continuous testing of deterministic families.

Agent-driven testing of access review, change management, and ITGC baseline families returns approximately 1,200–1,400 hours per year at 650-emp scale that flow to judgmental-family testing, design effectiveness evaluation, and external auditor coordination.

PCAOB AS 2201 & Inspection

01

PCAOB inspection reports 2024–2026 have validated agent-produced evidence meeting four characteristics: authenticity, completeness, source reliability, reperformability.

Authenticity via SHA-256 cryptographic hashing; completeness via continuous full-population testing; source reliability via direct read-only system integration; reperformability via preserved reasoning traces plus source-system query parameters. Document-centric evidence lacking cryptographic integrity, black-box automated evidence, and user-submitted attestation without independent verification are common exposure patterns.

02

PCAOB inspection reports 2023–2025 identify deficiencies at mid-market auditors when internal audit is understaffed relative to control population.

The 2024 annual report on broker-dealer and emerging-growth-company inspections specifically called out insufficient testing rigor on access review and change management at programs running at the thinnest 1 FTE per 60+ control ratios under manual testing. The inspection posture validates the traditional benchmark as the minimum defensible ratio.

03

PCAOB AS 2201 key sections for ITGC evidence: §.36, §.39, §.42, §.46, §.47, §.50.

§.36 identifies controls addressing significant risks. §.39 establishes evidence characteristics (authenticity, completeness, source reliability, reperformability). §.42 governs nature/timing/extent of tests. §.46 governs design effectiveness testing. §.47 governs operating effectiveness testing. §.50 governs deficiency evaluation (significant deficiency vs material weakness).

Continuous Control Testing

01

Agent-driven continuous testing covers 60–75 percent of IT General Controls at PCAOB AS 2201-aligned evidence bar in 2026.

High-confidence agent-testable families: access management (70–85 percent coverage), change management (65–80 percent), logging/monitoring (60–75 percent). ITGC operations baseline and configuration management reach 55–70 percent coverage. Design effectiveness (§.46) and deficiency severity (§.50) evaluations remain judgmental.

02

Continuous full-population testing produces evidence weight exceeding sample-based testing under PCAOB AS 2201 §.42.

Traditional sampling examines 25–40 records from a population under statistical inference; continuous agent testing examines 100 percent continuously. Sampling can miss deficiencies that population testing cannot, which appears as a first-year uptick in identified deficiencies (detection-quality improvement, not control deterioration).

AI agents credibly test 30–45 percent of a typical mid-market SOX control population today.

Agent-covered families: user access review, change management, ITGC baseline (backup, job scheduling, incident monitoring), entitlement-level SoD. Hybrid-coverage families: reconciliation, journal entry review. Human-only: estimate review, management review, anti-fraud program review, complex revenue recognition under ASC 606.

Regulatory Overlap

01

SOC 2 Trust Services Criteria CC6, CC7, CC8 overlap 85–90 percent with SOX ITGC.

CC6.1 (access) maps 90% to SOX access management. CC6.3 (access removal) maps 95% to terminated-user access. CC8.1 (change) maps 90% to SOX change management. CC7.2 (detection) maps 85% to logging/monitoring. A single evidence stream with framework-tag mappings serves both frameworks.

02

DORA (Regulation EU 2022/2554) entered into force January 17, 2025.

The regulation is directly applicable in all EU Member States. Approximately 62 percent of DORA Articles 5–14 ICT control activities map to SOX ITGC; 78 percent map to SOC 2 TSC CC7/CC8. Article 17 requires 4-hour initial incident notification. Article 28 cascades obligations through ICT third-party supply chains to US vendors.

CMMC 2.0 phased implementation runs October 2025–October 2028.

Phase 1 (Oct 2025): new contracts under $500K. Phase 2 (Oct 2026): full new-contract scope. Phase 3 (Oct 2027): renewal contracts. Phase 4 (Oct 2028): all remaining DoD contracts. Level 2 requires NIST SP 800-171 Rev 3 compliance (110 controls, triennial C3PAO assessment).

04

C3PAO Level 2 assessment cost runs $75,000–$180,000 per triennial cycle for 300–1,500 emp contractors.

Single-site 650-emp typically $95,000–$130,000. Multi-site 1,200-emp typically $150,000–$220,000. Pre-assessment readiness adds 400–1,000 internal hours plus $50,000–$150,000 external consulting. Ongoing maintenance 800–1,600 hours/year plus $50,000–$150,000 platform spend. 3-year aggregate: $350,000–$750,000.

EU AI Act general-purpose obligations took effect August 2, 2026.

Articles 51–55 govern general-purpose AI models; Articles 16–27 govern high-risk AI systems. Article 17 (record-keeping) and Article 13 (transparency) overlap with DORA Article 17 when incidents involve AI systems. ISO 42001 (AI management systems, published 2023) is the operational reference standard.
