Data recovery in Switzerland: how to verify your provider
Your data is about to leave your hands. Before entrusting a drive, a server or a phone, five two-minute checks show you, with sources to back them up, who you are contracting with, where your device will be processed and before which court you could act in the event of a dispute.
The findings of our documentary verification
We examined the data recovery providers visible on the Swiss market using public sources: legal notices, general terms and conditions, the commercial register (zefix.ch) and SOGC publications. The results of this verification, carried out in August 2026 (method and sources in the footnote):
A .ch domain, an 04x phone number or an address in a major Swiss city tell you nothing about the entity you are contracting with, nor about the place where your device will be processed. That information is found elsewhere: here is where to read it.
The 5 checks to make before entrusting your data
Read the legal notice, not the homepage
The legal notice (impressum) identifies the operator of the website. The counterparty to your contract, however, is designated by the general terms and conditions or the contract: the two do not always coincide, so check both. A .ch website can be operated by a company registered in another country: it is written there, but at the bottom of the page.
Check the company on Zefix.ch: free and official
The central commercial register (zefix.ch) tells you in ten seconds whether the company is registered in Switzerland, in what legal form, since when, and who represents it. Registration is not compulsory for all activities (a sole proprietorship below a certain turnover may not appear); but without registration you cannot verify the entity through this official channel, and that is in itself a piece of information.
Look for the place of jurisdiction in the terms and conditions
The place of jurisdiction designates the competent court in the event of a dispute. Read the relevant clause before sending in your device: it also states the law applicable to the contract. Its scope is not absolute: it depends on the applicable mandatory rules, particularly for consumer contracts. It nevertheless indicates where, and under which law, the provider intends to have disputes settled.
Look for the transfer and subcontracting clause
This is the clause that authorises sending your device to partner laboratories or subcontractors, sometimes with no geographical limit. Smartphones, memory chips and complex RAID configurations are the devices most frequently concerned.
Distinguish what is verifiable from what is merely claimed
A cleanroom with an ISO class, a certification, a success rate: ask for the certificate, the issuing body, the scope and the validity date. A “no data, no fee” guarantee may come with exceptions in the terms and conditions (analysis fees, express options, certain types of cases): read the exact conditions.
Documentary comparison of the main providers
Facts recorded in August 2026 from the providers' websites, terms and conditions and official registers (detailed sources in the methodology note). Four statuses: YES = documented by a verifiable source · CLAIMED = asserted by the provider, not independently verified · NOT DOCUMENTED = no information identified in the sources examined · NO = explicit source to the contrary.

Detailed comparisons, provider by provider
Regulated sectors: what the place of processing changes legally
For a private individual, choosing a provider is a matter of trust. For certain professions and institutions, the place of processing and the subcontracting chain additionally raise questions of professional secrecy, supervision and data protection, which require analysis before the device is sent.
Healthcare: doctors, hospitals, pharmacies, laboratories
Patient data is sensitive personal data (Art. 5 let. c FADP) and is covered by medical secrecy (Art. 321 Swiss Criminal Code), which also extends to the professional's auxiliaries.
IT service providers may, depending on the circumstances, qualify as auxiliaries within the meaning of Art. 321 Swiss Criminal Code. Using a provider or a subcontracting chain abroad is not automatically prohibited, but it requires reinforced analysis: professional secrecy, data access, contractual commitments, applicable law and the FADP's rules on international transfers. For patient data, the FDPIC notably recommends, as a precaution, avoiding a cloud provider abroad.
Banks and institutions supervised by FINMA
Banking secrecy (Art. 47 Banking Act) makes the disclosure of client data a criminal offence. Depending on the nature and importance of the engagement, FINMA's prudential rules on outsourcing (FINMA Circular 2018/3) may also be relevant: the institutions concerned must in particular ensure adequate risk management and sufficient control and audit rights and, where processing takes place abroad, take into account the additional risks associated with that location.
Lawyers and notaries
Art. 321 of the Swiss Criminal Code protects the professional secrecy of lawyers and notaries, and Art. 13 of the Lawyers Act (LLCA) requires lawyers to ensure that their auxiliaries respect it. An entirely Swiss processing chain, with no access from abroad, in principle avoids the issue of international data transfers; the contracting party, the applicable law and the place of jurisdiction must nevertheless be checked separately, and the professional remains bound to check the provider's confidentiality and security commitments. For fiduciaries and other accounting professions, obligations may arise in particular from the FADP, from the contract and, depending on the activity carried out, from other sector-specific rules.
Public administrations, municipalities, schools
Official secrecy (Art. 320 Swiss Criminal Code) and cantonal data protection laws apply to public bodies. Using a foreign entity may impose additional requirements or, depending on the applicable legislation and the nature of the data, limit the solutions that can be used: compliance must be analysed case by case (authority concerned, cantonal law, type of data, contractual and security guarantees, country of destination).
Sensitive federal engagements
Since 1 January 2024, the Information Security Act (ISA) has governed the processing of classified federal information. Where an engagement involves a sensitive activity, it goes through the company security procedure (PSE), which may result in a company security declaration (DSE).
Tesweb SA has completed the company security procedure (PSE) and holds a company security declaration (DSE). The employees who handle these engagements and access the secured laboratory hold “SECRET” level clearance issued by the State Secretariat for Security Policy (SEPOS). The document can be presented on request in the context of an engagement.
All companies: the FADP
Since 1 September 2023, the revised FADP has governed the disclosure of personal data abroad (Art. 16-17). It may notably rely on the recognition of an adequate level of protection or, failing that, on the safeguards provided for by law; Art. 17 also provides for certain exceptions in specific situations. The controller must furthermore keep control of its subcontracting chain (Art. 9): a processor may only engage another processor with the controller's prior authorisation; that authorisation may be general, in which case the processor must announce any change so that the controller can object.
Certain intentional breaches of FADP obligations, in particular of duties of care relating to subcontracting, security or the disclosure of data abroad, are criminally sanctioned; the maximum penalty under the FADP is a fine of CHF 250,000 and is aimed primarily at the responsible natural person (Art. 60 et seq. FADP).
What we document, and how to verify it
We apply the same standard of proof to our own row of the table as to the others: every element below is verifiable, and we tell you how.
A Swiss company, specialising in data recovery since 2006
SOS Data Recovery is a service of Tesweb SA (CHE-112.898.136), a public limited company registered in the Swiss commercial register: verifiable on zefix.ch. Since 2006, more than 11,300 devices have been processed in our laboratory. Our general terms and conditions provide for the exclusive application of Swiss law and jurisdiction in the canton of Bern.
A laboratory you can visit
Devices are opened in our laboratory in Switzerland, under ISO 5 certified laminar flow, certificate available on request; our laboratory is presented in detail on our dedicated page. You can hand in your device in person, at one of our 30 collection points in Switzerland, and visit our facilities by appointment. Our general terms and conditions commit us to this (Art. 3.1 “Place of Processing and Data Location”): your device, the working copies and the recovered data do not leave Switzerland, including for smartphones.
Verifiable references
Labels and certifications: Swiss Label (association for Swiss provenance), CyberSafe label (cyber-safe.ch association). 296 customer reviews on Avis Vérifiés, average rating 4.8/5 (a SKEEPERS group platform, NF Service certified). Our references and press articles: references page.
A free diagnosis within 3 hours
The diagnosis is free and without obligation, in under three hours of receipt: nature of the failure, chances of recovery and exact cost of the intervention, communicated in writing before any decision. Invoicing of the intervention is conditional on the recovery being at least 80 % successful.
Frequently asked questions
Does a CHE number on a website guarantee a Swiss company?
No. A CHE number may correspond to mere Swiss VAT registration, which is available to foreign companies selling into Switzerland. The proof is the entity's entry in the commercial register, verifiable free of charge on zefix.ch.
How do I know whether my data will leave Switzerland?
Read the general terms and conditions before sending in your device: look for the words “partners”, “subcontractors”, “central laboratory”, as well as the place of jurisdiction and the applicable law. Require written confirmation of the place of processing, including for smartphones, which are often handled at separate specialised sites.
Why does the place of processing matter?
For three reasons: the FADP's rules on disclosing data abroad, access to the courts (acting before a Swiss court is simpler and less costly than proceedings abroad), and the chain of custody, which matters for corporate, medical or professionally privileged data.
Is a cleanroom really necessary?
Opening a mechanical hard drive without damaging its platters requires a controlled-air environment. The useful questions to ask: which environment exactly (room, hood, laminar flow), which class, certified by whom, and can it be seen? An ISO class cited without a certificate or the possibility of a visit remains a claim.
Are smartphones treated differently?
Often, yes: recovery from soldered chips requires specific equipment, and several providers entrust them to specialised sites, sometimes abroad (at one major provider, the German version of the terms states: “Mobiltelefone und Tablets senden wir üblicherweise in unser Schwesterlabor nach Polen”, phones and tablets are usually sent to a sister laboratory in Poland). Ask explicitly where the extraction will be carried out.
I am a doctor, lawyer or banker: can I send a device abroad?
It is not automatically prohibited, but it requires reinforced analysis: professional secrecy (Art. 321 Swiss Criminal Code) or banking secrecy (Art. 47 Banking Act), the provider's contractual commitments, data access from abroad, the applicable law and the FADP's transfer rules. For patient data, the FDPIC recommends, as a precaution, avoiding a cloud provider abroad. If in doubt, consult your supervisory authority or your lawyer. An entirely Swiss chain, with no access from abroad, in principle avoids the international transfer issue; the contracting party, the applicable law and the place of jurisdiction still need to be checked separately.
Methodology note. The findings on this page rely exclusively on public sources consulted in August 2026: the legal notices and general terms and conditions of the providers cited, the central commercial register (zefix.ch), SOGC publications and the providers' own communications. Every finding is dated; the screenshots and exact references are kept on file.
