Sharing One Survey Login Across Clients Is a Liability

Running every client employee survey from one shared account concentrates sensitive feedback in one place. See what that risks and what to do instead.

Short answer

Running multiple clients' employee surveys out of one shared consultancy login turns your firm into the custodian of several companies' sensitive workforce data. Isolating each client in their own workspace with client-held encryption keys removes cross-client exposure and makes handover clean.

Most consultancies run every client's survey out of one account. It is not laziness; it is what the tools are shaped for. But it quietly makes your firm the custodian of several companies' most sensitive employee feedback, in a place none of them control, and that is a position worth looking at directly.

01What you are actually holding

Open the account and look at what is in there. Harassment climate results for one client. Layoff aftermath for another.

An upward review of a CEO who is still in post. Exit feedback naming a manager by pattern if not by name.

Now ask the questions your client's counsel would ask:

  • If your firm is subpoenaed in an unrelated matter, what is discoverable?
  • If an employee at Client A files a claim, and your account also holds Client B, what does disclosure look like?
  • When a consultant leaves your firm, what did they still have access to on the way out?
  • If your account is breached, how many companies do you have to notify, and who tells them?

None of these are exotic. They are the ordinary consequences of concentration, and the reason they rarely get raised is that nobody prices the arrangement until something happens.

02The shared password makes it worse

The account is usually shared, too, because per-seat pricing punishes a firm of six for behaving properly. So there is one credential, it is in a password manager and probably a Slack message from 2024, and the access log cannot tell you which of your people opened which client's results.

"Who at your firm has seen our employee feedback?" is a fair question from a client. "Everyone with the password, and I cannot tell you who used it" is not a good answer.

03An account per client is not the fix either

The obvious response is to have each client buy their own. Now the data is properly theirs, which is right, and you have added a procurement cycle to the front of every engagement, which is why it does not happen. Six-week project, three-week purchase. Most firms take the shared account instead, and honestly the incentives make that rational.

04Separate the workspaces, keep one login

The structure that works is per-client isolation with per-firm access:

  • A separate workspace per client, with its own key. Client A's results are not decryptable with Client B's key. There is no query that returns both.
  • One login for you, with a membership in each. Your people are named individuals, not a shared password, and the client can see exactly which of them can open their workspace.
  • The client owns theirs from day one. If that is only a promise, it is worth nothing at the moment it matters. Make it structural: we refuse to publish a survey in a client workspace until somebody at the client is an owner with their own key.
  • One bill, on your side. The client should not have to buy anything for their data to be theirs.

05What this does to the discovery question

It does not make your firm immune to a subpoena. Nothing does. What it changes is what a subpoena can reach.

If answers are encrypted in the respondent's browser and stored as ciphertext, then the survey vendor holding them cannot produce readable individual responses to anybody. What your people see is decrypted in their own browsers, by somebody the workspace gave a key to: scores as totals, and written answers word for word but shuffled and undated. Where the poll allows it, anyone who'd rather not be read can send just the topics they pick instead. Nothing on any server ties an answer to a person, so there is no file of who said what for anyone to be compelled to hand over, not because of a policy, but because it was never created.

That is a materially different conversation with a client's general counsel than "we take security seriously".

06The cheap version of doing this right

Move to a structure where each client's data is separate, the client owns it, and your access is a named membership you can end in one click. Then say so in your engagement letter, in one paragraph, because it is a genuine differentiator against every firm still running on a shared login.

No. Folders are organisation inside one account: same key, same access, same discovery scope. Separation has to be at the workspace and key level to change anything.
