Since the entry into force of the new LPD (nFADP) and the strengthening of the powers of the Federal Data Protection and Information Commissioner (PFPDT), the climate has changed in Switzerland. Audits are no longer science fiction.

A simple complaint from an unhappy customer ("I can't unsubscribe"), a whistleblower from a competitor, or a minor data leak can trigger an administrative investigation.

Unlike the European GDPR, which penalizes the company (fine % of revenue), the Swiss nFADP targets the personal criminal liability of executives (fine up to CHF 250,000 against the individual).

If the PFPDT knocks on your door tomorrow morning, they will not ask if you have "tried" to be compliant. They will ask for proof. Here are the 5 technical documents you must be able to produce within 48 hours.

1. The Processing Activities Register (Data Mapping)

This is fundamental. You need to know what data you collect, why, and where it goes.

The PFPDT's question: "Prove to me that you have control over your data flows."

What to provide: A comprehensive and up-to-date inventory.

  • Bad answer: "We use Google Analytics and Facebook, I think."

  • Good answer: A document listing each tool (Tag), the category of data (IP, Email, Behavior), the purpose (Marketing, Stats), the retention period, and the hosting location.

A-Track tip: A static Excel file created in 2023 is no longer sufficient. Your register must reflect the current technical reality of your site (which changes with each update).

Having a cookie banner on your site proves nothing. The PFPDT will want to verify that the banner actually works.

The PFPDT's question: "How do you prove that Mr. Dupont accepted advertising tracking on January 12, 2026, at 2:02 PM?"

What to provide: An extract of the logs from your CMP (Consent Management Platform). This file contains:

  • The consent ID (anonymous).

  • The date and time (Timestamp).

  • The version of the accepted privacy policy.

  • The details of the accepted categories (Marketing: YES, Stats: NO).

If you are using a free or poorly configured plugin that does not store these logs, you are legally exposed.

3. The Data Protection Impact Assessment (DPIA) for Transfers Outside Switzerland

If you use American tools (Google Ads, Meta, Mailchimp) or Chinese tools (TikTok), you are exporting data of Swiss citizens to countries deemed "inadequate" (unless under a specific DPF framework).

The PFPDT's question: "What technical measures have you taken to protect these transferred data?"

What to provide: Technical documentation proving that you minimize the risk. This is where Server-Side Tracking becomes your best advocate. It allows you to prove that you have:

  • Anonimized IP addresses before sending.

  • Hashed (pseudonymized) emails.

  • Blocked the sending of sensitive data.

Questions fréquemment posées

What documents does the nFADP require during an audit?

In case of an audit, the Federal Supervisor (nFADP) will mainly require 5 documents: 1) The updated processing activities register, 2) The consent logs proving that users have validated the cookies, 3) The impact assessment (DPIA) for data transfers outside of Switzerland, 4) The technical proof that trackers are blocked by default (Privacy by Design), and 5) The subcontracting contracts (DPA) with your service providers.

Who pays the nFADP fine in case of non-compliance: the company or the director?

Unlike the European GDPR which penalizes the company, the Swiss nFADP can penalize the responsible individual (Executive, CIO, DPO) if the violation is intentional. The fine can reach CHF 250,000 and must be paid personally by the individual, with no possibility of coverage by the company's insurance.
