Proton: a real alternative to GAFAM for your data?

For a long time, choosing digital tools seemed fairly straightforward.

For emails, you’d pick Gmail or Outlook. For files, Google Drive, OneDrive, or Dropbox. For meetings, Google Meet or Teams. For passwords, a browser-integrated manager. For VPN, a separate tool. For AI, yet another solution.

This model has a clear advantage: everything works fast, everything is familiar, and everything is already part of team habits.

But it also comes at a cost. Not just a financial one. A cost in dependency, data confidentiality, access control, and sometimes digital sovereignty.

That’s where Proton becomes interesting.

Proton isn’t just a secure email service. It’s a complete ecosystem that includes Proton Mail, Proton Calendar, Proton Drive, Proton Docs, Proton Sheets, Proton VPN, Proton Pass, Proton Meet, and Lumo, its privacy-focused AI assistant. Proton presents itself as an encrypted suite, based in Switzerland, with a data protection-centric approach and an ad-free model.

So the real question isn’t: “Is Proton more ethical than Google?”

The real question is: “Can Proton become a credible alternative to GAFAM for an SME without disrupting daily work?”

The short answer: yes, in many cases. But not without the right approach.
‍

Why SMEs are looking for alternatives to GAFAM

GAFAM won because they made digital simple.

One account, one inbox, one calendar, one cloud, shared documents, video calls, effective search. For an SME, it’s very tempting. You create the accounts, add collaborators, and the business runs.

The problem arises later.

When client files are scattered everywhere. When access permissions are no longer clear. When a former employee retains access rights. When a sensitive document ends up in the wrong folder. When a team uses free tools without approval. When no one really knows where company data is stored.

This is often when business leaders start considering GAFAM alternatives.

Not out of activism. Out of pragmatism.

An SME doesn’t need an alarmist discourse. It needs to know which tools truly protect its data, which ones simplify daily operations, and which ones create a dependency that’s hard to break.

This is exactly the topic of digital sovereignty for SMEs. And that’s also why a sovereign stack should never be thought of as a trendy list of tools. It should be designed as a work system.

‍

What exactly is Proton?

Proton is a Swiss company built around Proton Mail. Its positioning is straightforward: offering digital tools that are more privacy-respecting, with strong encryption and a subscription-based business model rather than advertising. Proton states it was founded in 2014 by scientists who met at CERN and now claims over 100 million accounts created.

Initially, Proton was primarily known as an alternative to Gmail.

Today, that’s no longer the case.

Proton aims to become an alternative to Google Workspace and Microsoft 365 for teams that want to better protect their data. Its business suite includes email, calendar, cloud storage, collaborative documents, video conferencing, VPN, password manager, and a private AI assistant.

This changes everything.

A company doesn’t replace Google or Microsoft with just one email service. It replaces them with a cohesive suite. Or at least with several well-connected components.

Proton positions itself in an interesting space: simpler than a fully self-hosted open-source stack, more private than traditional GAFAM suites, but less universal than Google Workspace or Microsoft 365.

It’s a compromise. And for many SMEs, that’s exactly what’s needed.

‍

Proton Mail: the most obvious alternative to Gmail

The first use case is Proton Mail.

For a business, email is often the most sensitive tool. It contains quotes, contracts, HR exchanges, invoices, customer requests, banking information, temporary access, and confidential documents.

It’s also the most targeted tool.

Phishing, fake suppliers, fake invoices, password theft, account takeover: many security issues start with email.

Proton Mail delivers a clear promise: a secure, encrypted email service based in Switzerland, designed to limit third-party access to content. Proton highlights end-to-end encryption and “zero-access” encryption, meaning Proton cannot read certain user data without permission.

For an SME, the benefits are tangible.

You can use a professional domain name. You can create addresses for your teams. You can better protect sensitive exchanges. You can also reduce your dependence on Gmail or Outlook, especially if your business handles customer, financial, legal, or strategic data.

Does that mean Proton Mail is perfect?

No.

Some teams very accustomed to Gmail may find the ecosystem less fluid at first. Some business integrations may require a bit of setup. And if your company already operates 100% within Google Workspace, with automations, scripts, shared documents, and advanced use cases, the migration needs to be prepared.

But to replace Gmail for secure email, Proton Mail is often the simplest entry point.

‍

Proton Drive: an alternative to Google Drive, but with some framing

After email, the second topic is storage.

Google Drive, OneDrive, and Dropbox have become go-to solutions. Everything goes there: client documents, accounting exports, signed contracts, marketing files, photos, internal materials, project data.

Here again, the question isn’t just practical. It’s also strategic.

Who can access the files?
Where are they stored?
What happens if an account is compromised?
How do you share a sensitive document?
Who removes access when a project is completed?

Proton Drive addresses this with a privacy-first approach. Proton presents it as end-to-end encrypted cloud storage, where only the user and selected individuals can access the files. Proton Drive also supports file sharing, password protection, expiration dates, and multi-device synchronization.

This is highly relevant for an SME looking to better control its business data.

But we must remain realistic.

If your team spends all day on Google Docs, Google Sheets, Google Slides—comments, suggestions, templates, scripts, and extensions—switching to Proton Drive needs to be tested. Proton offers Docs and Sheets, but Google’s collaborative ecosystem remains more mature for many advanced use cases. Proton is moving fast, but we shouldn’t confuse “credible alternative” with “perfect copy.”

The best approach is often to migrate by data type.

Sensitive documents can be prioritized for Proton Drive. Highly collaborative documents may temporarily stay in the current tool. Then, migration can expand as usage evolves.

This is also how you avoid failed migrations.

‍

Proton VPN: useful for mobile teams

VPNs are often misunderstood.

Many executives see them as tools reserved for technical profiles. In reality, Proton VPN can be useful in very simple scenarios: employees on the go, connections over public Wi-Fi, access to internal tools, secure browsing, and reducing risks on untrusted networks.

In Proton Workspace, the VPN is one of the solutions offered to businesses, alongside email, cloud storage, password management, and collaborative tools.

For an SME, the goal isn’t to “do what big companies do.” The goal is to give teams a simple tool to limit risky connections.

A salesperson working from a train station.
An executive reviewing documents from a hotel.
A consultant connecting from a client’s Wi-Fi network.
A remote team handling sensitive data.

In these cases, a well-configured VPN can become a useful building block for data protection.

It’s not a magic solution. It doesn’t replace good password management, two-factor authentication, properly set permissions, and a strong security culture. But it complements the whole setup well.

‍

Proton Pass: a real consideration for SMEs

If an SME had to improve one thing in security, it would often be password management.

In many companies, passwords are still stored in Excel files, notes, Slack conversations, shared browsers, or worse—only in one person’s head.

It’s fragile.

Proton Pass allows you to manage passwords, shared access, email aliases, and two-factor authentication depending on the plan. In business tiers, Proton highlights shared vaults, unlimited connections, notes, unlimited devices, “hide-my-email” aliases, passkey support, and dark web monitoring.

For an SME, this point can have more impact than a grand speech about cybersecurity.

A good password manager helps reduce weak passwords, avoid unsafe sharing, revoke access faster when someone leaves the company, and better separate personal and professional access.

It’s simple. It’s concrete. It’s often a priority.

‍

Can Proton replace Google Workspace or Microsoft 365?

Yes, but not always completely.

Proton can replace a large part of basic use cases: email, calendar, storage, file sharing, passwords, VPN, video calls, documents, and spreadsheets. Proton Workspace is even presented by Proton as a private alternative to Google Workspace and Microsoft 365 for teams.

But in a business, tools are never standalone.

They’re connected to the CRM, the website, the invoicing tool, accounting, customer support, the ERP, Notion, Airtable, Make, n8n, the HR system, forms, and automations.

That’s where things get interesting.

Switching tools without revisiting processes can create chaos. An SME shouldn’t just ask: “Does Proton replace Google?”

It should ask: “Which workflows currently depend on Google?”

Examples:

Does a form on the website send leads to Gmail?
Is a quote generated from a Google Sheet?
Does a salesperson share Drive folders with prospects?
Does an automation read attachments in a mailbox?
Are reporting dashboards in Google Sheets?
Are client accesses sent via Gmail?

If the answer is yes, these uses must be mapped before migrating.

This is exactly the logic of aSME automation or custom business software project: you don’t choose a tool in a vacuum. You start from the company’s actual workflows.

‍

The real benefits of Proton for an SME

The first advantage is the clarity of its positioning.

Proton doesn’t sell ads. Proton states that its revenue comes from subscriptions and that its services are not based on selling data. Proton also highlights open-source, audited applications and a privacy-centric model.

For an SME, this can become a trust argument.

A consulting firm can reassure its clients.
A company handling sensitive data can better frame its communications.
An association can protect its members.
A startup can limit intellectual property leaks.
A manager can regain control over critical tools.

The second advantage is the “suite” approach.

Proton Mail alone is useful. But Proton Mail with Proton Drive, Proton Pass, Proton VPN, and Proton Calendar becomes more cohesive. This avoids multiplying ten different providers to secure basic uses.

The third advantage is simplicity compared to a 100% self-hosted stack.

A full sovereign stack with Nextcloud, Matrix, Jitsi, dedicated servers, backups, managed services, monitoring, and internal procedures can be very powerful. But it requires more technical maturity.

Proton is a middle ground.

Less customizable than a self-hosted system. But more accessible for an SME that wants to move fast without overcomplicating things.

‍

The limitations to know before migrating

A good article about Proton shouldn’t sell a dream.

Proton has its limitations.

The first limitation is team adoption. Users are creatures of habit. Gmail, Drive, Outlook, Teams, and OneDrive are deeply embedded in many companies. Even if Proton is user-friendly, switching tools still means changing habits.

The second limitation is the integration ecosystem.

Google Workspace and Microsoft 365 are connected to almost everything. CRM systems, marketing tools, HR platforms, extensions, scripts, no-code connectors, automations, APIs, templates—their presence is massive. Proton is improving, but it doesn’t yet offer the same level of integration across all business tools.

The third limitation is advanced collaboration.

For simple documents, Proton Docs and Proton Sheets may suffice. For highly advanced use cases involving comments, workflows, templates, automations, and very specific work habits, testing is essential before making the switch.

The fourth limitation is the risk of confusing privacy with compliance.

Using Proton helps better protect certain data. But it doesn’t automatically make a company GDPR-compliant. The CNIL emphasizes that the roles of data controller and processor must be identified, as they determine each party’s obligations. Data processing by a processor must also be governed by a contract.

In other words: Proton is one piece of the puzzle. Not a compliance policy on its own.

‍

Proton and digital sovereignty: choose your words carefully

The word “sovereignty” is sometimes used too loosely.

Proton is based in Switzerland. It’s not a French provider. It’s not a SecNumCloud-certified solution. It may not be the right choice for all highly regulated sectors or for all critical data.

For a typical SME, Proton can be an excellent data privacy building block. For an organization with strict requirements regarding hosting, certification, public procurement, or highly sensitive data, a deeper analysis is needed.

This is where it’s important to distinguish between several levels:

A more privacy-respecting tool.
A European or Swiss solution.
A sovereign host.
A SecNumCloud-certified solution.
A truly controlled business architecture.

These levels do not mean the same thing.

If your topic is highly sensitive, Scroll’s article on SecNumCloud can help further the discussion. Proton may have its place in a more private stack, but it doesn’t replace a comprehensive analysis of risks, contracts, data, and use cases.

How to migrate to Proton without disrupting the business

The worst way to migrate is deciding on a Friday that the entire team will leave Google by Monday.

The best way is more measured.

We start with an audit.

Which tools are being used?
What data is being exchanged?
Which accounts are critical?
Which files are sensitive?
Which services depend on Gmail, Google Drive, or Microsoft 365?
Which team members will be most affected?
Which automations are at risk of breaking?

Then, we prioritize.

Often, the first components to migrate are the simplest: passwords, sensitive emails, executive accounts, confidential files, critical client folders.

Then we test with a small team.

A director. An administrative manager. A salesperson. A more technical person. This reveals the real friction points. Not the ones imagined in meetings. The real ones.

After this phase, we can scale up.

Migration can also be an opportunity to clean up the existing setup. Delete old accounts. Review permissions. Organize folders. Create a naming convention. Implement two-factor authentication. Document access. Define who can share what.

This work may seem less spectacular than choosing Proton. But it’s often what creates real security.

‍

And what about automations in all this?

Many SMEs want more confidentiality, but they don’t want to lose productivity.

That’s understandable.

No one wants to revert to manual processes just to protect their data.

The right approach is to connect Proton with the right tools, in the right places. For example, an incoming request can create a task. An email can feed a CRM. A document can trigger approval. A form can generate a project folder. A shared password can be revoked at the end of a mission.

On this topic, tools like n8n or Make can help create robust workflows. Scroll supports companies precisely on automation projects with n8nautomation with n8n, with a focus on framing, security, and robustness.

This is important because a migration to Proton shouldn’t just be a change of interface.

It should be an opportunity to build a cleaner system.

Less copy-pasting.
Fewer lost files.
Fewer carelessly shared passwords.
Less dependence on a single Google account.
Less sensitive data in unmanaged tools.

This is where Proton becomes interesting: not as a standalone tool, but as a building block in a better-organized system.

‍

Which businesses is Proton a good choice for?

Proton is particularly relevant for freelancers, consultants, consulting firms, agencies, associations, SME leaders, professionals handling sensitive exchanges, startups looking to protect their intellectual property, and teams seeking a Gmail alternative without switching to overly technical infrastructure.

It’s also interesting for companies that don’t want to abandon everything at once.

You can start with Proton Pass. Then Proton Mail. Then Proton Drive for certain folders. Then Proton VPN for mobile teams. Then expand if the use case is validated.

It’s a healthy approach.

Conversely, Proton should be considered more cautiously if your business heavily relies on advanced Google Sheets, macros, scripts, Microsoft 365 workflows, Teams, SharePoint, or deep business integrations.

In this case, Proton can remain a protective building block for certain uses without immediately becoming the main suite.

‍

Our take: Proton is a good gateway to a healthier stack

Proton isn’t magic. Proton doesn’t solve all digital sovereignty issues. Proton doesn’t always replace Google Workspace or Microsoft 365 100%.

But Proton has a real merit: it makes confidentiality more accessible.

For an SME, that’s already huge.

You don’t always need a complex infrastructure to start better protecting your data. You can already improve email, passwords, file sharing, and remote connections.

Next, you can go further.

Build a more sovereign stack. Rethink your automations. Connect your business tools. Replace certain Excel files with an internal app. Implement cleaner access rules. Secure your forms. Rethink your customer flows.

This is often where the real issue emerges: it’s not Proton vs. Google. It’s controlled organization vs. imposed tools.

‍

Now, shall we take back control of your tools?

Proton can be an excellent first step to gradually reduce dependence on GAFAM.

But success doesn’t just depend on the tool. It depends on the framework, usage, data, access, automations, and team adoption.

At Scroll, we support SMEs and entrepreneurs on these topics: tool audits, stack selection, automations, business apps, AI, no-code, and gradual migration to more reliable systems.

If you feel your current tools are practical but too scattered, or your sensitive data is circulating in too many places, now might be the right time to take stock.

You can schedule a meeting with Scroll or estimate your project to identify the first useful actions: securing access, migrating certain components to Proton, rethinking your workflows, or building a stack better suited to your business.
