Proton: a real alternative to GAFAM for your data?

For a long time, choosing digital tools seemed straightforward.

For email, it was 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 quickly, 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.

This is where Proton becomes interesting.

Proton is more than just secure email. 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-first 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 GAFAM alternatives

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 appealing. You create the accounts, add collaborators, and the business runs.

The problem arises later.

When client files are scattered everywhere. When access is no longer clean. When a former employee retains permissions. 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 leadership starts considering GAFAM alternatives.

Not out of activism. Out of clarity.

An SME doesn’t need alarmist rhetoric. It needs to know which tools truly protect its data, which simplify daily work, and which create a dependency that’s hard to leave.

This is exactly the topic of digital sovereignty for SMEs. And this is 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 value proposition is straightforward: offer digital tools that better respect privacy, 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 best known as an alternative to Gmail.

That is no longer the case.

Proton aims to become an alternative to Google Workspace and Microsoft 365 for teams seeking better data protection. 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 details, 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 this mean Proton Mail is perfect?

No.

Teams heavily accustomed to Gmail may find the ecosystem less fluid at first. Some business integrations may require some framing. And if your company already operates 100% within Google Workspace, with automations, scripts, shared documents, and advanced usage, the migration must be carefully prepared.

But for replacing Gmail with a secure email solution, Proton Mail is often the simplest entry point.

Proton Drive: a Google Drive alternative, but with caveats

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.

Once 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 revokes access when a project is complete?

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

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, Sheets, Slides, comments, suggestions, templates, scripts, and extensions, the switch to Proton Drive needs testing. Proton offers Docs and Sheets, but Google’s collaborative ecosystem remains more mature for many advanced use cases. Proton is evolving quickly, but we shouldn’t confuse “credible alternative” with “perfect replica.”

The best approach is often to migrate by data type.

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

This is also how you avoid failed migrations.

Proton VPN: useful for mobile teams

VPNs are often misunderstood.

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

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

For an SME, the goal isn’t to “act like a large corporation.” The goal is to give teams a simple tool to reduce 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 layer of data protection.

It’s not a magic solution. It doesn’t replace strong password management, two-factor authentication, properly set permissions, or a genuine 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 can have more impact than a grand speech on cybersecurity.

A good password manager reduces weak passwords, prevents unsafe sharing, revokes access faster when someone leaves the company, and better separates personal and professional access.

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

Can Proton replace Google Workspace or Microsoft 365?

Yes, but not always entirely.

Proton can replace most basic uses: 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, website, invoicing tool, accounting, customer support, ERP, Notion, Airtable, Make, n8n, HR system, forms, and automations.

That’s where things get interesting.

Switching tools without reviewing 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 site form send leads to Gmail?
Are quotes generated from a Google Sheet?
Does a salesperson share Drive folders with prospects?
Does an automation read attachments in an inbox?
Are reporting spreadsheets in Google Sheets?
Are client access details sent via Gmail?

If the answer is yes, you need to map these use cases before migrating.

This is exactly the logic behind a SME automation or custom business software project: you don’t pick a tool in a vacuum. You start with the company’s actual workflows.

Proton’s real advantages for an SME

The first advantage is the clarity of its positioning.

Proton does not sell ads. Proton states that its revenue comes from subscriptions and that its services do not rely on data monetization. Proton also highlights its open-source, audited applications and a privacy-first model.

These commitments are public and verifiable, which is a criterion in itself: Proton’s app code is open, and security audits are published, unlike most mainstream office suites, which allow no external inspection. For a business leader, the point isn’t to read the code but to have tangible proof to back up a commercial promise. Professional offering and detailed commitments: Proton for Business.

For an SME, this can become a trust-building 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 leader 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 use cases.

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

A fully sovereign stack with Nextcloud, Matrix, Jitsi, dedicated servers, backups, managed services, monitoring, and internal procedures can be very powerful. But it requires a higher level of technical maturity.

Proton is a middle ground.

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

Limitations to consider before migrating

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

Proton has its limits.

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

The second limit is the ecosystem of integrations.

Google Workspace and Microsoft 365 connect to almost everything. CRM, marketing tools, HR tools, extensions, scripts, no-code connectors, automations, APIs, templates: their reach is vast. Proton is improving, but it doesn’t yet offer the same level of integration across all business tools.

The third limit is advanced collaboration.

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

The fourth limit 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 reminds us 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.

This is the point most companies overlook when switching tools: compliance cannot be outsourced. The CNIL defines a processor as an organization that processes data "on behalf of" the controller, and responsibility remains with the latter. The contract must include four specific obligations for the processor: transparency and traceability, data protection by design and by default, security of processed data, and a duty of assistance, alert, and advice, including the procedure for notifying breaches. Switching email providers doesn’t check any of these boxes: your contracts and registry do. Official definition: the CNIL’s definition of a data processor.

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

Proton and digital sovereignty: mind the terminology

The word “sovereignty” is sometimes used too hastily.

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

This distinction is worth understanding rather than enduring, as it can be disqualifying in certain markets. SecNumCloud is the qualification awarded by ANSSI to cloud service providers, and it is required for some of the French state’s sensitive data and operators of vital importance. No amount of encryption replaces this qualification: it’s a security and legal framework, not a technical feature. If your tenders mention it, the decision is made before even comparing features. Framework and qualified providers: ANSSI’s SecNumCloud qualification.

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

This is where we need to distinguish several levels:

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

These levels do not mean the same thing.

If your topic is highly sensitive, Scroll’s article on SecNumCloud may complement the discussion. Proton can fit into a more private stack, but it doesn’t replace a full risk, contract, data, and usage analysis.

How to migrate to Proton without disrupting the business

The worst way to migrate is deciding on a Friday that the whole team leaves Google on Monday.

The best way is more measured.

Start with an audit.

Which tools are in use?
What data is being shared?
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 might break?

Then, prioritize.

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

Then test with a small team.

A director. An administrative manager. A salesperson. A technical person. This reveals the real friction points, not the ones imagined in meetings.

After this phase, you 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. Enable two-factor authentication. Document access. Define who can share what.

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

And what about automation in all this?

Many SMEs want more privacy, but they don’t want to sacrifice 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 an approval. A form can generate a project file. A shared password can be revoked at the end of a mission.

On this topic, tools like n8n or Make can help build robust workflows. Scroll supports companies on automation projects with n8n, with a focus on scoping, security, and reliability.

This matters because migrating 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 passwords shared carelessly.
Less reliance on a single Google account.
Fewer sensitive data in unmanaged tools.

This is where Proton becomes compelling: not as a standalone tool, but as a building block in a better-structured organization.

Which businesses is Proton a good fit for?

Proton is especially relevant for freelancers, consultants, consulting firms, agencies, associations, SME leaders, professionals handling sensitive exchanges, startups protecting their IP, and teams seeking a Gmail alternative without adopting overly technical infrastructure.

It’s also useful for companies that don’t want to switch everything at once.

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

This is a sensible approach.

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

In such cases, Proton can remain a protective layer for certain uses, without immediately becoming the primary suite.

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

Proton isn’t magic. It doesn’t solve every digital sovereignty issue. It doesn’t always fully replace Google Workspace or Microsoft 365.

But Proton has a real strength: it makes privacy more accessible.

For an SME, that’s already significant.

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

Then, you can go further.

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

This is often where the real issue emerges: it’s not Proton vs. Google. It’s controlled organisation 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 framing, usage, data, access, automation, and team adoption.

At Scroll, we support SMEs and entrepreneurs on these topics: tool audits, stack selection, automation, 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 book a meeting with Scroll or estimate your project to identify the first useful actions: secure access, migrate certain components to Proton, review your workflows, or build a stack better suited to your business.
