Cloud DLP in AWS, Azure, and GCP: A Practical Guide for India

Implementing data loss prevention in the cloud requires clarity on discovery, classification, policy enforcement, and incident response. This guide walks through platform-native options—AWS Macie, Microsoft Purview, and Google Cloud DLP—plus how Sentrix Axis operationalizes DLP with governance and managed response for India-based teams.

DLP building blocks

  1. Discovery: Inventory data stores across S3, EBS/EFS, RDS; Azure Blob/Files/SQL; GCS/Filestore/Spanner.
  2. Classification: PII/PHI/PCI detection using native classifiers and custom regex/dictionaries.
  3. Policy controls: Access governance, tokenization, encryption, and exfiltration monitoring.
  4. Monitoring & response: Alerting, triage, and guided remediation with IR playbooks.

Native tools overview

  • AWS Macie: Automates sensitive data discovery in S3 with ML-based classification.
  • Microsoft Purview: Unified data governance, sensitivity labels, and DLP policies across M365/Azure.
  • Google Cloud DLP: Powerful inspection templates, de-identification, and risk analysis APIs.

Cross-cloud guardrails

  • Identity: MFA, conditional access, least-privilege roles.
  • Encryption: KMS/CMK, rotation, envelope encryption patterns.
  • Network: Private endpoints, VPC Service Controls, Azure Private Link.
  • Observability: SIEM/XDR integration and DLP event normalization.

Compliance alignment for India

Map DLP controls to ISO 27001 Annex A, SOC 2, and regulator guidance (CERT-In and sectoral norms). Maintain auditor-ready evidence and reports with change tracking.

FAQs

Which cloud should I start with?

Start where your sensitive data resides today; we often prioritize S3 and M365 due to common exfiltration risks.

Can DLP slow down developers?

Good DLP emphasizes guardrails and observability first; we tune policies to minimize friction while reducing risk.

Do you support hybrid data estates?

Yes. We integrate on-prem and SaaS data sources with cloud platforms for full coverage.
