With your IT provider

Through TRU partners
We can provide migration and configuration services through our partners, under the agreed terms.
PROJECT PREPARATION
A migration plan that fits the way you work.
Choosing Proton Business solutions starts with the way your company works: the number of users, the email domains, the services needed and the data that has to be transferred.
The duration of the project depends on the current platform, the volume of data, the access available and the checks needed for users. Before setting the timetable, we also inventory the applications and devices that use email, to check how they will work after the switch.
What we check in the migration plan
- Users and addresses: the accounts, domains and aliases needed.
- Data to transfer: messages, contacts and calendars, depending on the source and the tools available.
- Way of working: devices, applications and your team’s access to the chosen services.
- Going live: responsibilities, the sequence of activities and the agreed functional checks.
Implementation is organised with the internal IT team, the client’s IT service provider or through TRU partners. The activities and support required are agreed before the project starts.

Why companies chose Proton.
Three situations in which information confidentiality became a priority for management.
Pharmaceutical manufacturing
Protecting know-how before a sale
Proton Business
Anonymised client experienceA pharmaceutical manufacturer was preparing for a sale. The asset inventory brought an essential part of the company’s value to the fore: the know-how and information built up over time, held largely in emails and shared documents.
Protecting this information became a priority for management. The company chose to implement Proton to improve the confidentiality of its correspondence and documents.
The case illustrates a decision to protect the information that underpins a business’s value, ahead of an important moment for the company.
Rolling stock repair
Correspondence forwarded outside the company
Proton Business
Anonymised client experienceAt a rolling stock repair plant, management noticed that several tenders were being lost by very small margins. It was later discovered that the company president’s messages were being forwarded to an external email address.
The discovery brought the confidentiality of correspondence into focus. The company chose to move to Proton Business to protect its communication.
In this case, the reason for the change was the exposure of business information through email.
Transport
Payment requests in the name of management
Proton Business
Anonymised client experienceAt a transport company, the finance department received payment requests in the name of the general manager, whose correspondence was being monitored. The team acted on the requests and the payments were made.
The incident showed the company that exposure of management’s correspondence can have direct consequences for financial processes. The company subsequently chose to move to Proton to protect its communications.
PROTON BUSINESS AND NIS2The encryption NIS2 requires,
The encryption NIS2 requires,
included in the subscription.
Proton Business natively covers the NIS2 encryption requirements: data encrypted in transit and at rest with zero-access encryption, traffic encrypted through a VPN, encryption keys under your control, sign-in with a physical security key and Proton Pass for passwords. No premium licences and no separate configuration.
| Requirement in OUG 155/2024, art. 13 | What Proton Business covers | What the company sets |
|---|---|---|
| Encrypting stored data, letter c) | Email, files, documents, calendar and passwords are stored with zero-access encryption. Not even Proton can read the content. Email received from outside Proton is encrypted on arrival. | The encryption policy and which data goes into each service. |
| Encrypting data in transit, letters c) and j) | Messages between Proton users are end-to-end encrypted. To recipients outside Proton, you send password-protected or PGP messages. | The rule for information sent outside the company. |
| Internet traffic, letter c) | Proton VPN, included in the subscription, encrypts the connection between the device and the VPN server, including on public Wi-Fi, and blocks malicious domains. | When a VPN connection is mandatory. |
| Encryption keys, letter c) | Private keys stay under the company’s control: they are protected by the users’ passwords and Proton has no access to them. You can generate, import or export them. | The procedure for the key lifecycle: generation, replacement, recovery. |
| Multi-factor authentication, letter j) | The administrator enforces 2FA for all users, with an authenticator app or a FIDO2 physical security key. | The authentication rule and a record of physical keys. |
| Access control, letter f) | Proton Pass keeps passwords, 2FA codes and other secrets in encrypted vaults, shared only with those who need them. | Who has access to what and how access is removed when an employee leaves. |
Who holds the keys
At Proton, zero-access encryption is standard for all data, unlike the big-tech suites. At Microsoft 365 and Google Workspace, data is encrypted, but the provider holds the keys. Your own keys require the top-tier plans.
| Proton Business | Microsoft 365 | Google Workspace | |
|---|---|---|---|
| Stored data is encrypted | Yes, zero-access | Yes | Yes |
| Who holds the keys in the regular plans | The company | Microsoft | |
| Customer-held keys | Standard, for all data | Double Key Encryption and Customer Key, with Microsoft 365 E5 or Microsoft Purview add-ons | Client-side encryption, in Enterprise Plus, Frontline Plus and Education |

Proton Business covers the encryption, authentication and access-control measures. NIS2 compliance also requires the other measures in OUG 155/2024, which the auditor checks.
COMPATIBILITY AND MIGRATION
We check how your business actually works.
You can keep your company’s domain and import email from supported IMAP providers using Easy Switch. Contacts and calendars are checked separately, depending on the source. Data import and address activation are planned before email routing is switched.
On desktop, compatible clients can use Proton Mail Bridge with a paid plan. We check the exact version of Outlook: Proton warns of synchronisation issues with New Outlook for Mac and recommends alternatives. Exchange workflows, delegated access, applications that send email and complex documents are tested in a pilot.
