One Fix, Four Frameworks: How Cross-Framework Compliance Mapping Works

The Compliance Silo Problem

A compliance officer at a healthcare AI company manages three regulatory obligations: HIPAA, SOC 2, and the EU AI Act. Each framework has its own audit trail, its own control library, and its own remediation process.

One morning, an internal audit reveals that audit logging is insufficient across their AI inference pipeline.

Under the current process, this triggers three separate workflows:

1. HIPAA team files a remediation task for 45 CFR 164.312(b) — Audit Controls
2. SOC 2 team files a remediation task for CC7.1 — System Operations Monitoring
3. EU AI Act team files a remediation task for Article 12 — Record-Keeping

Three teams. Three tickets. Three timelines. One root cause.

This is not an edge case. This is the default operating model for multi-framework compliance. And it is profoundly wasteful.

Why Frameworks Overlap More Than You Think

Regulatory frameworks are written by different bodies, in different countries, at different times. But they are all trying to solve the same fundamental problems: accountability, transparency, security, and fairness.

The result is massive overlap. Consider these control categories and how they map across frameworks:

| Control Category | SOC 2 | ISO 27001 | EU AI Act | HIPAA | NIST CSF | GDPR | |-----------------|-------|-----------|-----------|-------|----------|------| | Audit Logging | CC7.1 | A.12.4.1 | Art. 12 | 164.312(b) | DE.CM-1 | Art. 30 | | Access Control | CC6.1 | A.9.2.3 | Art. 14 | 164.312(a) | PR.AC-1 | Art. 32 | | Risk Assessment | CC3.2 | A.8.2.1 | Art. 9 | 164.308(a)(1) | ID.RA-1 | Art. 35 | | Incident Response | CC7.3 | A.16.1.1 | Art. 62 | 164.308(a)(6) | RS.RP-1 | Art. 33 | | Data Protection | CC6.7 | A.10.1.1 | Art. 10 | 164.312(a)(2) | PR.DS-1 | Art. 32 |

Five control categories. Six frameworks. Thirty overlapping requirements.

If you treat each framework as a silo, you are doing the same work six times.

How Cross-Framework Mapping Works

HAIEC's Compliance Twin uses a control normalizer that maps 70+ individual controls from 9 frameworks into 13 normalized control categories.

When a compliance check fails, the system does not just tell you which rule failed. It tells you which normalized control category is affected, and then maps that category across every framework in your regulatory mix.

The process:

1. Rule fails — e.g., SOC 2 rule "Audit logging must be enabled" returns FAIL
2. Control identified — The rule maps to normalized control NC-03 (Audit Logging)
3. Cross-framework lookup — NC-03 maps to SOC 2 CC7.1, ISO 27001 A.12.4.1, EU AI Act Article 12, HIPAA 164.312(b), NIST CSF DE.CM-1, GDPR Article 30
4. Impact assessment — The system shows you: this single failure affects 6 frameworks
5. Unified remediation — One remediation step resolves the root cause across all 6

The 13 Normalized Control Categories

Every control in every framework maps to one of these categories:

| ID | Category | Frameworks Covered | |----|----------|-------------------| | NC-01 | Risk Assessment | SOC 2, ISO 27001, ISO 42001, EU AI Act, NIST CSF, HIPAA | | NC-02 | Access Control | SOC 2, ISO 27001, EU AI Act, HIPAA, NIST CSF, GDPR | | NC-03 | Audit Logging | SOC 2, ISO 27001, EU AI Act, HIPAA, NIST CSF, GDPR | | NC-04 | Data Protection | SOC 2, ISO 27001, EU AI Act, HIPAA, GDPR, CCPA | | NC-05 | Incident Response | SOC 2, ISO 27001, EU AI Act, HIPAA, NIST CSF, GDPR | | NC-06 | Change Management | SOC 2, ISO 27001, ISO 42001, NIST CSF | | NC-07 | Vendor Management | SOC 2, ISO 27001, ISO 42001, EU AI Act | | NC-08 | Human Oversight | EU AI Act, ISO 42001, NYC LL144, Colorado AI Act | | NC-09 | Bias & Fairness | NYC LL144, Colorado AI Act, EU AI Act, ISO 42001 | | NC-10 | Transparency | EU AI Act, NYC LL144, Colorado AI Act, GDPR | | NC-11 | Model Governance | ISO 42001, EU AI Act, NIST CSF, SOC 2 | | NC-12 | Documentation | SOC 2, ISO 27001, ISO 42001, EU AI Act, HIPAA | | NC-13 | Continuous Monitoring | SOC 2, ISO 27001, NIST CSF, EU AI Act |

This is not a theoretical mapping. It is built into the compliance engine and executed on every rule check.

A Real-World Example

A fintech company in Colorado deploys an AI lending model. Their regulatory obligations include:

• Colorado AI Act (SB 24-205) — High-risk AI deployer obligations
• SOC 2 — Required by enterprise customers
• GDPR — European customer data
• NIST CSF — Industry best practice

An auto-audit detects that their model lacks adequate documentation of training data sources. This triggers:

Without cross-framework mapping:

• Colorado AI Act team: "We need to document training data per SB 24-205 Section 3"
• SOC 2 team: "We need model documentation per CC1.4"
• GDPR team: "We need data processing records per Article 30"
• NIST team: "We need asset documentation per ID.AM-2"
• Four tickets, four teams, four timelines

With cross-framework mapping:

• One failure detected → NC-12 (Documentation) identified
• Cross-framework impact: Colorado AI Act, SOC 2, GDPR, NIST CSF
• One remediation: "Document all training data sources including origin, collection date, preprocessing steps, and retention policy"
• Effort estimate: 4-8 hours
• One ticket resolves all four frameworks

The Math of Efficiency

For an organization under 4 frameworks with 10 control categories in scope:

• Without mapping: 40 individual control checks, 40 potential remediation tasks
• With mapping: 10 normalized checks, 10 potential remediation tasks (each resolving up to 4 framework-specific controls)

That is a 75% reduction in remediation overhead. Not because you are doing less compliance — but because you are not doing the same work four times.

For organizations under 6+ frameworks, the efficiency gain approaches 80-85%.

Why This Required a New Approach

Existing compliance tools treat frameworks as separate modules. You buy the SOC 2 module, the HIPAA module, the GDPR module. Each has its own control library, its own assessment workflow, its own remediation tracker.

This architecture makes cross-framework mapping impossible. The tools were not designed to understand that SOC 2 CC7.1 and ISO 27001 A.12.4.1 and EU AI Act Article 12 are all asking for the same thing.

HAIEC's control normalizer was built from the ground up to understand these relationships. It is not a bolt-on feature. It is the foundation of how the compliance engine works.

Every rule, every check, every remediation flows through the normalizer. Cross-framework impact is not an optional report — it is the default view.

What This Means for Your Organization

If you operate under multiple regulatory frameworks — and most AI companies do — cross-framework compliance mapping changes the economics of compliance.

Instead of scaling your compliance team linearly with each new framework, you scale logarithmically. Each new framework adds incremental effort, not multiplicative effort.

One fix. Four frameworks. That is not a tagline. It is the architecture.
