DORA
EU regulation for digital operational resilience in finance
ISA 95
International standard for enterprise-manufacturing integration.
Quick Verdict
DORA mandates ICT resilience for EU finance against cyber threats via testing and reporting, while ISA 95 provides voluntary models for manufacturing IT/OT integration. Finance adopts DORA for compliance; manufacturers use ISA 95 to reduce integration costs and errors.
DORA
Regulation (EU) 2022/2554, Digital Operational Resilience Act
Key Features
- Mandates comprehensive ICT risk management frameworks
- Enforces 4-hour incident reporting for disruptions
- Requires triennial threat-led penetration testing (TLPT)
- Oversees critical third-party ICT providers directly
- Harmonizes resilience rules across 27 EU states
ISA 95
ANSI/ISA-95 Enterprise-Control System Integration
Key Features
- Purdue levels 0-4 hierarchical model
- Activity models for manufacturing operations
- Object models for equipment and materials
- Standardized Level 3-4 transactions
- Alias services for identifier mapping

DORA Details
What It Is
DORA (Regulation (EU) 2022/2554) is an EU-wide regulation enhancing digital operational resilience for the financial sector against ICT risks like cyberattacks and failures. It applies to 20 financial entity types (~22,000 entities) and critical third-party providers (CTPPs), using a proportional, risk-based approach for harmonized oversight.
Key Components
- **ICT risk management frameworksIdentification, mitigation, annual reviews by management.
- **Incident reporting4-hour initial, 72-hour updates for major incidents (>5% users or €100k losses).
- **Resilience testingAnnual basic tests, triennial TLPT.
- **Third-party oversightContracts, monitoring, ESAs supervision of CTPPs. Built on four pillars with reporting to authorities; penalties up to 2% global turnover.
Why Organizations Use It
Mandated compliance avoids fines, mitigates threats (74% ransomware hit), boosts resilience post-outages like CrowdStrike. Enhances trust, enables info sharing, drives cybersecurity investments (€10-15B EU-wide).
Implementation Overview
Conduct gap analyses per RTS/ITS (2024), develop frameworks/testing/vendor strategies. Proportional to size/complexity; for EU financials. No certification but authority audits, remediation; leverage tools for monitoring.
ISA 95 Details
What It Is
ISA-95 (ANSI/ISA-95, IEC 62264) is an international framework standard for integrating enterprise business systems like ERP with manufacturing operations and control systems such as MES/SCADA. It organizes activities into Purdue levels 0-4, focusing on the Level 3-4 interface with models for consistent information exchange.
Key Components
- Hierarchical levels 0-4 (process to business planning)
- Activity models (Part 3), object models for equipment/materials/personnel (Parts 2/4)
- Eight parts including transactions (Part 5), messaging/alias services (Parts 6-8)
- Compliance via architectural alignment; certificate programs available
Why Organizations Use It
- Reduces integration risk, cost, errors; enables semantic consistency
- Supports IT/OT collaboration, data governance, Industry 4.0
- Drives OEE improvement, traceability, agility
- Builds stakeholder trust through standardized exchanges
Implementation Overview
- Phased: assessment, canonical modeling, pilot, rollout
- Involves cross-functional governance, data mapping
- Applies to global manufacturing; voluntary adoption
