A Private, Compliant Cloud Storage Option for Small Businesses

Most small businesses store their files on one of the big-name cloud platforms without thinking too hard about it. The files sync, sharing works, and everyone moves on. The part that rarely gets asked: can the company hosting your files actually read them?

For a lot of mainstream cloud storage, the honest answer is yes. The provider holds the keys, so in technical terms it can access your files. For a marketing agency that might not matter. For a law firm, a medical practice, a financial advisor, or a nonprofit handling donor records, it matters quite a bit.

This page explains a different option (Proton Drive for Business), what its privacy and compliance claims actually mean in plain English, and where it makes sense for a small business. No fear tactics. We will tell you up front that Norvet is a Proton affiliate, and what that means for you.

A few terms worth knowing first

Three phrases come up constantly in this space. If you know what they mean, the rest of the page is easier to follow.

End-to-end encryption means your files are scrambled on your own device before they ever leave it, and only you (and the people you share with) hold the keys to unscramble them. The data travels and sits on the server already locked.

Zero-access architecture is the follow-on promise: because the provider never holds your keys, the provider itself cannot read or decrypt your files, even if it wanted to or was compelled to. Proton says this is how Proton Drive is built.

SOC 2 Type II is an independent audit standard. It means an outside auditor reviewed the provider's security controls over a period of time and confirmed they actually operate the way the provider claims. It is a checkmark a lot of business and healthcare buyers look for.

What Proton Drive for Business is

Proton Drive for Business is secure cloud storage, file sharing, and a built-in documents tool called Proton Docs that supports real-time collaboration (several people editing the same document at once). It is part of a wider encrypted suite that also includes Proton Mail, Calendar, VPN, and Pass.

The thing that sets it apart is the encryption model described above. Proton says files are end-to-end encrypted and that its zero-access architecture means Proton cannot read or decrypt your data. Proton also states it does not use your data to train AI, that the software is open source, and that it has been independently audited.

Proton was built by scientists and engineers who came out of CERN, the European physics research organization. The company hosts its data in Switzerland, which has some of the strongest privacy law in the world. Proton says its business products are trusted by over 50,000 organizations.

The compliance and storage details

For regulated small businesses, the specifics matter more than the marketing. Here is what Proton publishes.

Compliance support

Proton says Proton Drive for Business supports GDPR, HIPAA, and ISO 27001 requirements. It states that it is ISO 27001 certified and that it has been independently audited for SOC 2 Type II. If you handle protected health information or EU resident data, those are the standards your auditor and your clients will ask about.

A note for honesty: a tool supporting HIPAA requirements is not the same as your business being HIPAA compliant. Compliance is about how your whole organization handles data, not one app. The right tool makes it much easier, but you still need the policies and the paperwork (a Business Associate Agreement, for example) to go with it.

Storage and version history

Proton lists 1 TB of storage per user and up to 10 years of file version history. That version history is quietly one of the most useful features here. If a file gets overwritten, corrupted, or hit by ransomware, you can roll back to an earlier copy.

Sharing controls

You can share files with passwords, set expiry dates, and revoke access after the fact. External collaborators can upload files to you without needing a Proton account of their own, which is handy when a client or vendor needs to send you something securely.

Why this matters for a small business

The cost of getting data handling wrong is not abstract. IBM's Cost of a Data Breach 2024 report put the global average cost of a breach at $4.88 million. That figure is skewed by large enterprises, so do not read it as your bill. Read it as the reason regulators and insurers care so much about how you store data.

On the regulatory side, GDPR fines can reach 20 million euros or 4% of annual revenue, whichever is higher. Most small Atlanta businesses are not GDPR targets, but if you serve EU clients or partners, it can apply to you.

The point is not to scare anyone. It is that the businesses with the most to lose from a storage breach are often the smallest ones: the solo law practice, the two-person accounting firm, the local clinic, the nonprofit. Those are exactly the verticals where end-to-end encrypted storage earns its keep. Legal, healthcare, finance, nonprofits, and consultancies all handle sensitive records that a client trusts them to protect.

Where Norvet MSP fits in

Norvet MSP is a managed IT and security provider based in the Atlanta area. We work with small businesses that do not have a dedicated IT team, and with ones that do but need an extra set of hands.

A tool like Proton Drive is only as good as the way it gets rolled out. Migrating your existing files without breaking links, setting up user accounts and sharing rules, training your team so they actually use it, and folding it into the rest of your security stack: that is the part we handle. We can set it up and manage it for you as part of a managed IT plan, so you get the privacy benefit without the migration headache.

If your business handles records you would not want a third party reading, this is worth a short conversation.
