Know what’s inside your files before they reach the cloud.

Scan for common secrets and personal information, review the risk, optionally redact detected patterns, and store only files that pass the server-side upload policy. Every scan and storage decision is recorded in an audit log.

① Scan a file

Files are checked by the server before any storage action. Supported: TXT, MD, CSV, JSON, LOG · maximum 5 MB.

⇧

Choose a file to inspect

Scans text-based TXT/CSV/JSON/LOG, PDF, and modern Word (.docx) files for configured sensitive-data patterns. Max 5 MB; scanned/image-only PDFs and legacy .doc files are not supported.

No file selected

Redact detected patterns before storing
Attempts to replace common credentials, emails and phone-like numbers. For PDF/Word files, redaction exports extracted text as a .txt file and does not preserve the original formatting. Review the result yourself; automated redaction is not guaranteed to catch every sensitive value.

🔐 Security rule: the server rescans the file at upload time. Critical/high findings block storage unless the redacted file passes the same checks. A clean scan does not prove a file is safe.

② Storage & audit

Review files stored by CloudShield and the latest security events.

CloudShield academic prototype · Local demo mode stores files on this computer. Configure a private S3 bucket to demonstrate cloud storage mode. Do not upload real credentials or personal data during testing.
