ISA 95 vs MLPS 2.0 (Multi-Level Protection Scheme)
ISA 95
Framework for enterprise-manufacturing control integration
MLPS 2.0 (Multi-Level Protection Scheme)
China's regulation for graded cybersecurity system protection
Quick Verdict
ISA 95 provides voluntary models for manufacturing-IT integration worldwide, while MLPS 2.0 mandates graded cybersecurity in China. Companies adopt ISA 95 for efficient operations; MLPS 2.0 for legal compliance and enforcement avoidance.

ISA 95 Details
What It Is
ISA-95 (ANSI/ISA-95, IEC 62264) is a technology-agnostic international standard and reference framework for integrating enterprise business systems with manufacturing operations. Its primary purpose is defining consistent information models, boundaries, and exchanges between Level 4 (ERP/logistics) and Level 3 (MES/MOM) using the Purdue hierarchy (Levels 0-4). It employs hierarchical, activity, and object modeling approaches.
Key Components
- Eight parts covering models/terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging (Part 6), aliases (Part 7), profiles (Part 8).
- Core Purdue levels, equipment hierarchies, shared semantics for materials/equipment/personnel/production.
- No formal product certification; compliance via architectural alignment and training certificates.
Why Organizations Use It
Reduces integration risk, cost, errors; enables semantic consistency, IT/OT collaboration, regulatory traceability. Drives OEE improvements, scalable rollouts, Industry 4.0 readiness. Builds stakeholder trust through auditable data governance.
Implementation Overview
Phased program: assessment, canonical modeling, pilots, rollouts. Applies to manufacturing firms globally; requires cross-functional governance, security segmentation. No mandatory audits; self-assessed via KPIs and maturity models.
MLPS 2.0 (Multi-Level Protection Scheme) Details
What It Is
China's Multi-Level Protection Scheme 2.0 (MLPS 2.0) is a mandatory regulatory framework under the 2017 Cybersecurity Law. It classifies information systems into five levels based on compromise impact to national security, social order, and public interests, requiring graded technical, governance, and organizational controls.
Key Components
- Common controls across physical security, networks, data protection, and operations; extended for cloud, IoT, big data, ICS.
- Standards like GB/T 22239-2019, GB/T 25070-2019; ~75/100 audit score threshold.
- Governance structures, personnel management, incident response.
- Third-party audits, PSB approval for Level 2+.
Why Organizations Use It
- Legal enforcement by PSBs avoids fines, suspensions.
- Reduces cyber risks, ensures resilience.
- Enables market access, procurement in China.
- Builds regulator, stakeholder trust.
Implementation Overview
- Phased: scoping, classification, gap analysis, remediation, audits, ongoing monitoring.
- Targets China network operators, critical sectors; multi-year program with annual re-evals.
