Cloud Storage Exposure Check – Public Bucket and Blob Scan

Publicly readable cloud storage is behind a remarkable share of the leaks you read about. Nobody ever chooses it on purpose.

The Cloud Storage Exposure Check tests whether the storage buckets and containers associated with your business can be listed or read by an anonymous stranger — exactly the way an outsider would find out, using no credentials at all.

What it checks

• Whether named storage buckets and containers respond to an anonymous request
• Whether their contents are publicly listable — the difference between one shared file and your whole archive
• Whether individual objects can be read without authentication
• Bucket names derived from your domain and brand, which is how they get found in the first place
• Storage endpoints referenced directly by your own website

What you get

• A written PDF report emailed back to you, typically within one business day.
• Every exposure rated Critical / High / Medium / Low, with what an anonymous visitor can currently see.
• Provider-specific instructions for closing the access without breaking your site.
• Guidance on the settings that stop it recurring.
• Reporting built to CompTIA Security+ and PenTest+ practice standards.

Who it's for

Businesses using cloud storage for backups, media, customer documents or website assets — particularly where a developer or agency set it up and moved on.

Requirements

• Windows 10 or Windows 11
• Run as administrator
• An internet connection
• Your domain and any storage names you want checked — they must be yours
• About 5 minutes

What this is not

QuickScan is detection and advisory only. It makes the same anonymous request any visitor could; it never downloads your data, never uses credentials, never exploits a weakness, and changes nothing. Only run it against storage you own or are authorised to test. It is not a certification, an audit or an attestation.
