Company

A focused product for one hard question.

Access Witness exists because SharePoint Online administrators keep being asked who had access to something in the past, and the platform cannot answer. We build one product to answer that question well, and we run it on your infrastructure.

What we believe

How we build

  • Explainable over impressive

    An access answer is only useful if it shows the path, the actor and the confidence. We would rather say Unknown than guess.

  • Private by architecture

    Permission history is sensitive. It stays in your database, on your host, behind your network. The vendor sees license metadata and nothing else.

  • Honest about Microsoft 365

    Audit events arrive late, throttling is real, and SharePoint Online cannot be scanned without Microsoft connectivity. The product and the website say so.

  • Useful without buying

    The technical blog is written to solve problems with PowerShell and Microsoft Graph on their own. The product is for when that is no longer enough.
