Segregation of Duties Controls

Problem class

32% of companies report material weaknesses from SoD issues and 40% fail at least one SOX control annually. Periodic manual access reviews catch conflicts months after they appear, leaving the window open for fraud and audit findings.

Mechanism

A controls engine ingests role and permission data from every financial system, evaluates against a SoD ruleset (e.g., "cannot create vendor + approve payment"), and surfaces conflicts in real time. Provisioning workflows reject conflict-creating role grants at request time rather than at audit time.

Required inputs

• Role and permission inventory across financial systems
• SoD conflict matrix (industry-standard + customized rules)
• HR-driven joiner-mover-leaver triggers
• Approval routing for exception requests

Produced outputs

• Real-time conflict alerts
• Preventive blocks on conflicting role grants
• SOX-ready audit evidence
• Risk quantification by transaction exposure

Industries where this is standard

• SOX-regulated US public companies
• Global banks under regulatory examination
• Pharmaceutical with FDA Part 11 requirements
• Defense contractors with DCAA compliance
• Critical infrastructure operators

Counterexamples

• Very small finance teams (<5 people) where structural SoD is impossible — compensating controls (review, dual sign-off) are the only realistic option.
• Pre-IPO startups before SOX applies — premature investment burns cash on controls auditors won't ask about for 2+ years.

Representative implementations

• Midstream oil & gas company — SAP GRC Access Control 12.0 with Protiviti; 99% SoD conflict reduction at single-role level, automated provisioning via SuccessFactors triggers.
• Global fast-food chain — SafePaaS deployment; 99% SoD conflict reduction with real-time risk visibility across global operations.
• Saviynt composite (BP, Western Digital, MassMutual via Forrester TEI) — 240% ROI over 3 years, $34.4M total benefits including $8.6M from SoD automation, 90% reduction in employee onboarding time.
