Who can see your documents

The question everyone asks before uploading anything, answered with what can be checked.

Updated on 13/08/2026

It is the first serious question anyone asks before putting their clients' documentation somewhere new, and it deserves an answer you can check rather than a promise. There are three separate circles, and it helps to look at them one at a time.

The three circles

WhoWhat they seeHow you check it
Your teamWhatever their role and permissions allowThe activity log: it says who opened what and when
Third parties you inviteOnly their own, or what you grantThe same log, with their name
The platform's providersWhat operating the service requiresThe public subprocessor list and what you signed

Important

Over the first circle you have full control and proof: **every access is logged, including read-only ones**. That means the answer to "who has seen this document?" does not depend on trusting anyone, not even inside your own company. It is the most underestimated point when evaluating a tool and the most valuable the day there is a suspicion.

What to ask for in writing before signing

  1. 1

    Where the data is hosted

    Country and infrastructure provider, not "in the cloud".

  2. 2

    Which subprocessors are involved and for what

    There should be a public, current list, with notice when it changes.

  3. 3

    In what cases support accesses, and with what trail

    The right question is not whether they can, but when and what is recorded.

  4. 4

    And what happens at the end

    How you take everything with you and what is deleted, with timeframes.

Watch out

Be sceptical of "nobody on our team can see anything". In any service run by people, someone administers the infrastructure, and claiming otherwise is a simplification that collapses in the first serious audit. The credible answer is not that it is impossible: it is **what is restricted, what is logged and what you signed** — that is what an auditor checks and what you can demand.

What you can do to shrink the circle

The last is the least technical and the most effective: not everything that exists in your company has to live in any tool.

Worth knowing

If a client sends you a security questionnaire, these are the same questions they will put to you — and a public subprocessor list is part of an answer you can give without negotiating anything.

Can I find out whether someone viewed a specific document?

Yes, in the activity log, with name and time.

Does the assistant see more than I do?

No: it answers with what your permissions allow you to see.

What if I need a formal answer for a client?

Ask for it in writing and keep it with that client's documentation.

A real case

The situation

An advisory firm hesitates to upload its clients' documentation to a new tool.

What you do

  2. Checks that the activity log also records views

What you get

Signs with an answer it can show its own clients when they ask.

What you get

Sensitive material stays where it should.

The situation
