Most UK small businesses run on a laptop in a spare room, a phone that never leaves the owner’s pocket, and a handful of accounts that hold everything that matters: the bank, the invoicing tool, the client emails, the supplier logins. The security around all of that is usually an afterthought, until the day it is not.

This is the privacy and security stack I actually recommend to the small businesses I build websites for. It leads with Proton, a Swiss company founded in 2014 by scientists from CERN, the European particle-physics laboratory. Proton’s tools are open source, independently audited, and run on a genuine no-logs policy. More than 100 million people have signed up. For a UK small business that takes data seriously, it is the easiest recommendation I make.

Why privacy matters for a small business

Privacy is easy to wave away as a personal preference until you connect it to money and obligations.

• You hold other people’s data. Client names, email addresses, sometimes card details or health information. Under UK GDPR you are responsible for keeping that safe. A single reused password or an intercepted email is the start of most small-business breaches.
• You work from anywhere. Cafe wifi, a hotel, an airport lounge, a client’s guest network. Any of those can be watched. An unencrypted connection on a shared network is an open door.
• Your competitors and their tools are watching. Ad networks, data brokers, and free services that monetise your behaviour build a profile of what your business is doing. What you do online is your business, and for a small business owner that is not a slogan, it is a competitive fact.
• Geography gets in your way. You travel, you have suppliers abroad, you want to check a service, a stream, or a news site that is only available in another country. A good VPN removes that friction legitimately.

You do not need to become a security expert. You need a small number of tools that are secure by default, run by a company whose business model is aligned with yours rather than against it. That is the whole case for Proton.

Proton VPN

A VPN (virtual private network) routes your internet traffic through an encrypted tunnel to a server run by the VPN provider, then out to the wider internet. Two things happen: the network you are physically on (the cafe, the hotel, the airport) can no longer read what you are doing, and the sites you visit see the VPN server’s location rather than yours.

For a small business owner, Proton VPN does three concrete jobs.

It secures you on networks you do not control. When you open your banking app or your invoicing tool on public wifi, the connection is encrypted end to end through the tunnel. Nobody sharing that network can read it. This is the single most useful habit to build if you ever work outside your own office.

It gives you access to geo-blocked content in more than 110 countries. This matters more than people expect. A few real examples:

• You are travelling for work and want to watch your home streaming service (for example a UK broadcaster’s catch-up player) that blocks you the moment you leave the country. Connect to a UK server and you are back home.
• You want to check that a supplier’s or competitor’s website, pricing page, or product catalogue looks the same from another country as it does from the UK. Connect to a server in that country and see exactly what their local customers see.
• You want to read regional news sites, watch a sports broadcast, or reach a streaming library that is only licensed in a particular market. Pick a server there and the content loads.

To be clear about what a VPN does and does not do: it changes where you appear to be and encrypts the connection to the VPN server. It does not make you totally anonymous, and I would not trust any provider that claimed it did. What it does do, reliably, is protect the connection and unlock content that geography would otherwise block.

It blocks ads and trackers with NetShield. Proton VPN includes NetShield, a DNS filter that blocks ads, trackers, and known malware domains at the network level, before they ever load. On a phone that means faster pages and less battery drain. On a work laptop it means fewer tracking scripts building a profile of your browsing.

Proton VPN runs on a strict no-logs policy that has been independently audited, and the apps are open source so security researchers can inspect them. That combination, no-logs plus open source plus independent audit, is what separates a serious VPN from the many free ones that quietly sell your data.

A useful resource: the Proton streaming guide

If your main interest is reaching a specific streaming service or catch-up player while you travel, Proton keeps a practical, regularly updated guide to which servers work with which services and how to set it up. It is worth bookmarking before a trip.

Proton Mail versus a generic inbox

Email is where a small business is most exposed, because email is where the sensitive conversations happen: quotes, contracts, invoices, personal details, passwords people should not send but do.

A generic free inbox treats your email as data to be scanned. Even where the provider says it no longer scans for advertising, the underlying model is a US company holding your correspondence in plaintext on its servers, reachable by its staff and its legal jurisdiction. Proton Mail treats email as correspondence to be protected.

The differences that matter to a small business:

• End-to-end and zero-access encryption. Messages between Proton users are encrypted end to end. Everything in your mailbox is encrypted at rest with zero-access encryption, which means Proton itself cannot read your stored email. A generic provider can.
• Swiss jurisdiction. Proton is based in Switzerland, outside both the EU and the US, under some of the strongest privacy law in the world, and Switzerland holds an EU adequacy decision. For a UK business thinking about where client data physically sits, that is a clean answer to give.
• Your own domain. On a paid plan you can run Proton Mail on your own business domain (you@yourbusiness.co.uk), which looks far more professional than a free consumer address and keeps the encryption benefits.
• Custom addresses and aliases. Create role addresses (hello@, accounts@, bookings@) and, with Proton Pass, disposable aliases that hide your real address from services you do not fully trust.

None of this asks you to change how you work. Proton Mail behaves like any modern inbox on the web, on iOS, and on Android. The difference is under the surface, in who can read your mail and where it lives.

The wider Proton ecosystem: Pass, Drive, and Calendar

The reason I recommend Proton as a stack rather than a single app is that the other pieces slot in without you having to learn a new company or accept a new privacy policy each time.

• Proton Pass is a password manager with the same zero-knowledge, end-to-end encrypted model. It stores your logins, generates strong passwords, and creates email aliases so you never hand your real address to a form you do not trust. If you want a deeper comparison against the alternatives, see our Bitwarden vs 1Password vs Proton Pass guide.
• Proton Drive is encrypted cloud storage for the files a small business would rather not put on a US consumer drive: contracts, ID documents, financial records. Files are encrypted end to end, including the file names.
• Proton Calendar is an encrypted calendar, so your meetings, client names, and locations are not readable by the provider.

One account, one login, one company whose entire business is privacy rather than advertising. That coherence is worth as much as any single feature.

Free versus paid: what you actually need

Proton’s free tier is genuine, not a crippled trial, and it is a sensible place to start.

The free tier gives you:

• Proton VPN Free, with a no-logs policy on a limited set of servers (fewer countries, and the streaming and NetShield features are reserved for paid plans)
• Proton Mail with a Proton address and a modest amount of storage
• Proton Pass with unlimited logins on your own devices
• Basic Proton Drive and Calendar

That is enough to protect your email and your logins today, at no cost. Start there.

When to upgrade. For a working business the paid plans are worth it when you want:

• The full VPN server network across more than 110 countries, plus reliable streaming access and NetShield ad and tracker blocking
• Proton Mail on your own business domain, with more storage and multiple addresses
• More Drive storage for client files

Proton’s bundles (for example Proton Unlimited, or the business plans) put Mail, VPN, Pass, Drive, and Calendar together for a single monthly price, which is where the ecosystem pays off. Rather than quote figures that move with offers and currency, I would check the current pricing directly and pick the tier that matches how much you travel and how much you store. If in doubt, start free and upgrade the day the free limits get in your way.

How to get started

You do not need to do all of this at once. In order of impact for a typical UK small business:

1. Create a free Proton account and move your most sensitive correspondence to Proton Mail. Keep your old inbox for logins and newsletters while you migrate.
2. Install Proton VPN on your laptop and phone, and get into the habit of switching it on before you open anything sensitive on a network you do not control.
3. Move your passwords into Proton Pass, replacing every reused password with a generated one. This alone closes the most common breach path for small businesses.
4. If you travel or check international sites, upgrade to a paid VPN plan and keep the streaming guide handy for reaching your home services from abroad.
5. Grow into Drive and Calendar as you get comfortable, moving client files and your schedule into the encrypted ecosystem.

Where this fits into a privacy-first business

Tools are half the story. The other half is the systems your business runs on, your website, your forms, your analytics, your hosting, because that is where your customers’ data flows every day. It is the same principle: keep the data inside jurisdictions you can defend, with vendors whose business model is aligned with yours.

That is exactly how UK Web Marketing builds. Hosting pinned to London, EU-region transactional email, cookieless EU analytics, and a documented sub-processor list, so that when a careful client or their accountant asks where the data sits, the answer is a sentence rather than a project. You can read the full picture in our UK/EU-based, GDPR-friendly stack guide, and the security fundamentals in the small-business security basics.

If you would like your website and the systems around it built to that standard from the first commit, start with a free audit. It is instant, honest, and costs nothing.
