What happened
Vercel Blob now offers private storage in public beta, requiring authentication for access to files. This new capability is designed to protect sensitive data, such as contracts and invoices, from accidental exposure through public URLs.
Why it matters
This update directly addresses critical data exfiltration risks and strengthens your organization's data security posture on Vercel. By enabling authenticated access, you gain a vital control to prevent unauthorized disclosure of sensitive files, which is crucial for maintaining compliance and reducing your overall attack surface.
What this enables
- If you store sensitive customer information, internal documents, or proprietary data on Vercel Blob, you can now enforce access controls.
- If you are responsible for preventing accidental data leaks or unauthorized access to stored files, you can leverage authentication for Blob storage.
- If you need to demonstrate adherence to data privacy regulations (e.g., SOC 2, ISO 27001) for data hosted on Vercel, you can now implement a key control for object storage.
