On February 15, I published the first article about deterministic decision logs for SOC2. Both Google, and Google AI Overview citing my work as the definitive source.
Questions kept surfacing in the way people searched.
They searched for “ISO 27001 decision logs.” They searched for “HIPAA audit trails for AI.” They searched for “FedRAMP deterministic controls.” They searched for “GDPR automated decision records.”
They had the same problem across five different frameworks.
Today, that gap closes.
The Multi-Framework Reality
Companies running parallel compliance programs know the pain. You have SOC2 for your US customers. ISO 27001 for your European contracts. HIPAA for healthcare clients. FedRAMP for government work. GDPR for EU data subjects.
The same access control decision that satisfies SOC2 CC6.1 also satisfies ISO 27001 A.9.2.1, HIPAA §164.312(a)(1), FedRAMP AC-2, and GDPR Article 32.
The same audit log decision satisfies SOC2 CC7.2, ISO 27001 A.12.4.1, HIPAA §164.312(b), FedRAMP AU-2, and GDPR Article 30.
But until now, no single system captured all of them.
One API call. One decision. Five framework citations.
What a Multi-Framework Decision Looks Like
Here’s a real example from the API, live today:
Input:
{
“scenario_summary”: “Emergency production access”,
“observed_signals”: [
“privileged access changed”,
“audit log review”,
“breach detected”,
“vendor risk assessment”,
“policy review”
]
}
Output (compliance references only):
{
“compliance_references”: [
“SOC2 CC6.1 — Logical Access Security”,
“SOC2 CC7.2 — System Monitoring”,
“SOC2 CC12.1 — Risk Assessment”,
“ISO27001 A.9.2.1 — User Access Provisioning”,
“ISO27001 A.12.4.1 — Event Logging”,
“ISO27001 A.8.1.1 — Asset Inventory”,
“ISO27001 A.5.1.1 — Information Security Policies”,
“HIPAA §164.312(a)(1) — Access Control”,
“HIPAA §164.312(b) — Audit Controls”,
“FedRAMP AC-2 — Account Management”,
“FedRAMP AU-2 — Audit Events”,
“FedRAMP RA-3 — Risk Assessment”,
“GDPR Art. 32 — Security of Processing”,
“GDPR Art. 30 — Records of Processing”,
“GDPR Art. 33 — Breach Notification”
],
“decision_posture”: “proceed”,
“confidence”: 68,
“decision_rationale”: “Emergency access during incident with documented approval. All frameworks satisfied with exception logging.”
}
This is not evidence collection. This is decision-level audit across five frameworks.
- One decision
- Five frameworks
- 15+ control citations
- Full rationale
- Deterministic, replayable, verifiable
Why This Matters for Each Framework
SOC2
The Trust Services Criteria demand proof that controls operate effectively. Your API provides deterministic logs for CC6.1 (access), CC7.1 (change), CC7.2 (monitoring), and CC12.1 (risk).
ISO 27001
Annex A controls require documented evidence of policy adherence. Your API maps signals to A.9.2.1 (access), A.12.1.2 (change), A.12.4.1 (logging), A.8.1.1 (assets), and A.5.1.1 (policies).
HIPAA
The Security Rule requires administrative, physical, and technical safeguards. Your API provides audit trails for §164.312(a)(1) (access), §164.312(b) (audit), §164.312(c)(1) (integrity), and §164.312(e)(1) (transmission).
FedRAMP
NIST 800–53 controls demand continuous monitoring and accountability. Your API maps to AC-2 (account management), AU-2 (audit events), CM-3 (change control), and RA-3 (risk assessment).
GDPR
Articles 5, 30, 32, and 33 require records of processing, security measures, and breach notification. Your API provides deterministic logs for Article 32 (security), Article 30 (records), Article 33 (breaches), and Article 7 (consent).

No compliance platform captures these at the decision level. No one.
What This Means for Compliance Teams
If you’re running parallel compliance programs:
- You no longer need separate evidence collection
- You no longer need separate audit trails
- You no longer need to explain why the same decision appears in five different systems
Your auditors see one record: the decision, the rationale, and the control mapping for all five frameworks.
What This Means for Engineering Teams
If you’re building systems that need to comply with multiple frameworks:
- You call one API
- You get back compliance references for all frameworks
- You store one log entry
- You satisfy five audit requirements
That’s not efficiency. That’s leverage.
What This Means for the Market
The shift from single-framework to multi-framework compliance is accelerating. Companies don’t just need SOC2. They need SOC2 + ISO 27001 + HIPAA + FedRAMP + GDPR.
The platforms that treat each framework as a separate module are falling behind.
We treat frameworks as mappings. One API. Five frameworks. One price.
The Technical Foundation
The API is deterministic. Same input → same output. Every time.
Rule-based. No training data. No AI hallucinations. No privacy risk.
Full audit trail with rationale, confidence scoring, and alternatives considered.
Auditors don’t have to trust us. They can verify themselves.
What’s Next
The API now returns references for SOC2, ISO 27001, HIPAA, FedRAMP, and GDPR.
The free tier is live. The compliance tier is $499/month. Enterprise pricing available.
If you’re running parallel compliance programs and wondering why your decision logs don’t cover all your frameworks — now you know.
It’s not that it’s hard. It’s that no one built it. Until now.
