What is ISO 27001 Annex A.8.12?
Annex A.8.12 is the ISO 27001:2022 control for data leakage prevention. It expects organizations to prevent sensitive information from being disclosed or transferred without authorization.
ISO 27001 Annex A.8.12 requires organizations to prevent sensitive information from leaving approved systems, users and channels. TRIAS DLP helps security and compliance teams discover sensitive data, classify it, monitor risky activity, block leakage paths and produce audit-ready evidence.
Create policy, incident, classification and monitoring evidence that supports ISO 27001 internal and external audits.
Control endpoint, USB, email, browser upload, cloud transfer, file sharing and insider-risk channels.
Turn Annex A.8.12 from a policy statement into enforceable technical data protection.
Annex A.8.12 focuses on preventing data leakage from systems, networks and endpoint devices. A practical implementation needs sensitive data visibility, channel controls, user activity monitoring, incident workflows and evidence that policies are operating effectively.
TRIAS DLP combines discovery, classification, endpoint control, device control and activity monitoring so organizations can define what must be protected and enforce how it may be used.
TRIAS DLP supports ISO 27001 Annex A.8.12 by identifying sensitive data, enforcing data leakage policies across endpoints and channels, monitoring user activity and producing audit evidence for data loss prevention controls.
| Requirement | TRIAS DLP support |
|---|---|
| A.5.12 Classification of information | Data discovery and classification policies identify regulated, confidential and business-critical information. |
| A.5.13 Labelling of information | Labels and policy tags can drive DLP enforcement and watermarking workflows. |
| A.5.34 Privacy and protection of PII | PII detection and leakage prevention support GDPR and KVKK obligations. |
| A.8.1 User endpoint devices | Endpoint DLP controls risky local copy, print, upload and removable media use. |
| A.8.12 Data leakage prevention | Core DLP policies prevent unauthorized transfer of sensitive data. |
| A.8.15 Logging | Events, violations and investigations provide audit evidence. |
| A.8.16 Monitoring activities | User and file activity monitoring supports insider threat detection. |
Annex A.8.12 is the ISO 27001:2022 control for data leakage prevention. It expects organizations to prevent sensitive information from being disclosed or transferred without authorization.
ISO 27001 does not mandate one specific product, but organizations with sensitive data usually need DLP-like controls to demonstrate effective data leakage prevention.
Useful evidence includes DLP policies, classification rules, incident logs, investigation records, user activity monitoring and remediation workflows.
Yes. The same discovery, classification and leakage controls can support personal data protection obligations under GDPR and KVKK.
