Monitor S3 Bucket Changes & Integrity Audit with Mistral AI

This n8n workflow provides automated, scheduled integrity audits for AWS S3 buckets, capturing snapshots to detect unexpected changes like additions, deletions, modifications, renames, or moves caused by users, applications, tenants, or ransomware. It compares current and previous bucket states to identify altered objects, downloads changed files (focusing on text-based formats like TXT, PDF, and logs), applies OCR for text extraction, and leverages Mistral AI to analyze changes for sensitivity and completeness, ensuring data integrity.

Key benefits include proactive ransomware detection, prevention of data loss, compliance assurance, and reduced manual oversight for storage admins. It works with any cloud provider (adaptable to Azure or Google Cloud) and runs on customizable schedules (hours, days, weeks), alerting on anomalies to maintain secure, compliant storage environments.

Ideal for cloud architects, DevOps teams, and storage administrators managing critical data. Use cases: auditing multi-tenant S3 buckets, monitoring logs for tampering, verifying backups against corruption, or ensuring regulatory compliance in finance/healthcare. Setup involves configuring AWS credentials, Mistral API, and snapshot storage.
