Our verdict on each
Internxt
Internxt bundles encrypted storage, mail and a no logs VPN into a single open-source account, which suits people who want one provider rather than a stack of separate tools. The trade-off sits at entry: the free allowance is small, and paid storage starts at €9.99.
Proton
Proton bundles a password manager, VPN and encrypted storage in one account, with Pass starting at $4.99 and a free tier. It suits readers who want passwords, private files and a VPN in a single subscription, and who can live with free plan limits that leave out an authenticator, password sharing and file attachments.

Pros and cons
Internxt
Pros
- Open source, so the client code can be read by anyone, and the logging policy says passwords and user data are not stored, with data encrypted in transit and at rest.
- The drive product lists ISO 27001:2022, HIPAA and GDPR and is aimed at business buyers.
- Apps on Windows, macOS and Linux put storage, mail and VPN on the same account across desktop and mobile.
Cons
- The free tier is 1 GB of encrypted cloud storage, free for life, the smallest free allowance here: MEGA gives 20 GB free, Degoo 20 GB, and Apple 5 GB.
- The VPN reaches 5 server countries, well below the 48.5 country median here.
- Support runs on email, chat and help centre only, so answers arrive in writing or in chat.
Proton
Pros
- A single account covers a password manager, a VPN and end-to-end encrypted storage, with a free plan to start.
- Passkeys, custom domains and a Family plan with an admin panel suit single-user and shared use.
- Vaults use AES-GCM encryption with OpenPGP and ECC keys, and only the account holder can decrypt.
Cons
- Support runs on email, chat and help centre with no phone line.
- Free plan limits leave out the authenticator app, password sharing, attachments and dark web monitoring.
- Extra storage costs $95.88 per TB per year beyond 5 GB free.
Who each suits
Internxt
Who it suits
- Readers who want storage, mail and a VPN from a single open-source provider rather than separate subscriptions.
- Business buyers, since the drive product lists ISO 27001:2022, HIPAA and GDPR and the suite is aimed at business.
Who should look elsewhere
- Free-library seekers: MEGA gives 20 GB free and Degoo 20 GB, against 1 GB here.
- People who need a wide server map: a larger VPN covers more countries than 5.
- Storage-only buyers: Apple bundles 5 GB of free space into an account many already hold.
Proton
Who it suits
- Readers who want a password manager, a VPN and private files under a single subscription rather than separate products.
- Households and small teams that need shared accounts, since the Family plan bundles several Pass Plus accounts and an admin panel.
- Buyers who care about open source under a copyleft licence, outside security audits and a public bug bounty.
Who should look elsewhere
- Apple Hide My Email at $0.99 if email aliasing is the whole job, since Proton adds a VPN, storage and a password manager.
- Apple Inc. at $0.99 when aliasing is the priority; Proton's $4.99 entry brings a VPN, storage and password manager in the same account.
- EasyOptOuts at $19.99 for a single higher priced subscription, against Proton's $4.99 entry and a free plan.

Questions about each
Internxt
What does the free plan include?+
The free plan covers 1 GB of encrypted cloud storage, free for life. That is a small starting allowance, and the paid tiers are where real volume sits. It is enough to try the encryption setup on a few files before committing to a subscription, and the free tier is listed as free for life.
How much does Internxt cost to start?+
Entry pricing is €9.99, and Internxt is listed across both free and budget tiers. Paid subscriptions come with a 30 day money-back window, so a first subscription can be reversed. A free plan also exists, so paying is a choice rather than a requirement.
Proton
How much is Proton Pass at the entry price?+
Proton Pass starts at $4.99, and there is a free plan beside it. The paid tiers widen the set of features, so the entry price only pays off if you want more hide my email aliases, passkeys and password health alerts.
What does the free plan leave out?+
The free plan covers as many logins, notes, cards and devices as you like, but it leaves out the authenticator app, sharing with other people, file attachments and dark web monitoring. Those sit on paid Pass plans, where entry starts at $4.99.
