ISO 27001 for Clinical Trials: Information Security Management That Regulators Respect
How ISO 27001's information security management framework applies to clinical trial technology, what the 93 controls cover, and why alignment matters for your EDC platform.
What Is ISO 27001?
ISO 27001 is the international standard for Information Security Management Systems (ISMS). Published by the International Organization for Standardization, it provides a systematic framework for managing information security risks through a combination of policies, processes, and technical controls.
The 2022 revision (ISO 27001:2022) reorganised its controls into four themes with 93 total controls — down from 114 in the 2013 version. For clinical trial technology, this framework provides a structured approach to securing patient data, trial integrity, and operational availability.
The Four Control Themes
ISO 27001:2022 organises its 93 controls into four categories. Here is how they map to clinical trial EDC requirements.
┌─────────────────────────────────────────────────────────┐

└─────────────────────────────────────────────────────────┘Key Controls for EDC Platforms
Not all 93 controls are equally critical for clinical trial technology. Here are the ones that matter most.
Access Control (A.5.15-A.5.18, A.8.2-A.8.5)
- A.5.15 Access control policy: Documented rules for who can access what
- A.5.16 Identity management: Unique identifiers for every user
- A.5.17 Authentication: Strong authentication mechanisms
- A.5.18 Access rights: Principle of least privilege
EDC application: Role-based access control with site-scoped data isolation. Users see only the studies and sites they are assigned to. Administrative access is separate from clinical data access.
Cryptography (A.8.24)
- A.8.24 Use of cryptography: Encryption policy covering data at rest, in transit, and key management
EDC application: AES-256 field-level encryption for PII, TLS 1.3 for all communications, Argon2id for password hashing, and documented key management procedures.
Logging and Monitoring (A.8.15-A.8.16)
- A.8.15 Logging: Event logging for user activities, exceptions, and information security events
- A.8.16 Monitoring activities: Continuous monitoring of networks, systems, and applications
EDC application: Immutable audit trails logging every data change, access, and system event. Automated anomaly detection for unusual access patterns. Log retention aligned with clinical trial archival requirements.
Secure Development (A.8.25-A.8.31)
- A.8.25 Secure development lifecycle: Security integrated into development processes
- A.8.26 Application security requirements: Security requirements defined for all applications
- A.8.27 Secure system architecture: Security by design principles
- A.8.28 Secure coding: Coding standards that prevent vulnerabilities
- A.8.29 Security testing: Automated and manual security testing
- A.8.31 Separation of environments: Development, testing, and production isolation
EDC application: Automated security scanning in CI/CD pipelines, dependency vulnerability monitoring, code review requirements, and strict environment separation with no production data in development.
Supplier Management (A.5.19-A.5.23)
- A.5.19 Information security in supplier relationships: Security requirements for all suppliers
- A.5.21 Managing information security in the ICT supply chain: End-to-end supply chain security
EDC application: Cloud infrastructure provider compliance (SOC 2, ISO 27001 certified data centres), subprocessor management, and data processing agreements.
The ISMS Approach: Plan-Do-Check-Act
ISO 27001 is not a list of controls — it is a management system based on continuous improvement.
┌─────────────────────────────────────────────────┐
│ │
│ ┌──────────┐ │
│ │ PLAN │ Risk assessment, │
│ │ │ define controls, │
│ │ │ set objectives │
│ └─────┬────┘ │
│ │ │
│ ┌───────────▼───────────┐ │
│ │ DO │ Implement controls, │
│ │ │ train staff, │
│ │ │ operate ISMS │
│ └───────────┬───────────┘ │
│ │ │
│ ┌────────▼────────┐ │
│ │ CHECK │ Monitor, measure, │
│ │ │ audit, review │
│ └────────┬────────┘ │
│ │ │
│ ┌──────▼──────┐ │
│ │ ACT │ Correct, improve, │
│ │ │ update policies │
│ └─────────────┘ │
│ │
│ This cycle runs CONTINUOUSLY — not annually │
│ │
└─────────────────────────────────────────────────┘For clinical trial technology, this means:
- Plan: Assess risks specific to clinical data (patient safety, data integrity, regulatory penalties)
- Do: Implement technical controls (encryption, access control, audit trails, monitoring)
- Check: Continuous compliance testing, penetration testing, access reviews, incident analysis
- Act: Address findings, update controls, improve processes
ISO 27001 vs SOC 2: Complementary, Not Competing
| Aspect | ISO 27001 | SOC 2 |
|---|---|---|
| Origin | International (ISO/IEC) | US (AICPA) |
| Focus | Management system | Operating effectiveness |
| Output | Certificate (valid 3 years) | Report (annual) |
| Scope | Entire ISMS | Specific system/service |
| Audience | Global | Primarily North American |
| Clinical trial relevance | EU sponsors prefer it | US sponsors prefer it |
The best clinical trial technology platforms pursue both. ISO 27001 demonstrates systematic risk management; SOC 2 demonstrates operational effectiveness of controls.
What “ISO 27001 Aligned” Actually Means
Some vendors claim “ISO 27001 alignment” without formal certification. Here is what the term means and what to verify:
Certified (ISO 27001:2022): An accredited certification body has audited the ISMS and issued a certificate. This is independently verified and publicly defensible.
Aligned: The organisation has implemented controls consistent with ISO 27001 but has not been formally certified. This can be genuine (controls are in place, certification is in progress) or marketing (controls are partial or aspirational).
How to verify:
- Ask for the certificate or the certification timeline
- Request a Statement of Applicability (the document listing all 93 controls and their implementation status)
- Ask which controls are implemented, which are planned, and which are excluded (with justification)
- Check whether the vendor has an internal or external audit programme
Your EDC Vendor’s Security Framework Matters More Than Their Marketing Claims
Here is the uncomfortable truth: most EDC vendors claim compliance alignment without the evidence to back it up.
They put badges on their website. They check boxes on RFI responses. But when you ask for the Statement of Applicability, the penetration test results, or the risk treatment plan — silence.
Clinical trial data is not just sensitive data. It is data that affects patient safety, regulatory decisions, and drug approvals. The information security framework protecting that data should be auditable, systematic, and continuously improving.
PharmaTrialsCortex is built with ISO 27001 controls embedded in the platform architecture:
- 93 controls mapped to our security programme with documented applicability
- Risk-based approach — security controls proportional to the sensitivity of clinical trial data
- Continuous compliance testing — automated verification of controls in every deployment
- Secure development lifecycle — security scanning, code review, dependency monitoring, environment isolation
- Formal certification actively in progress
We do not just claim alignment. We document it, test it, and prepare for independent audit.
Schedule a security review — we will walk your team through our Statement of Applicability, our risk register, and our control evidence. Bring your CISO. We are ready.
The question is not whether your EDC vendor has security controls. The question is whether they can prove it.
