Best Cloud Storage With End-to-End Encryption

Every file you put in Proton Drive is end-to-end encrypted by default, its cheapest paid plan is $3.99 a month for 200 GB, and the company answers to Swiss law, which makes it the simplest answer here. MEGA matches that 200 GB for $3.88 and gives away 20 GB free, four times Proton's 5 GB, with the same zero-knowledge encryption on the free account.

The column that matters most is Encryption Coverage, because not everything on this list encrypts everything. Six services do it for all files from the moment you sign up. pCloud and Icedrive encrypt only a separate Crypto folder, and Apple iCloud+ does it only after you switch on Advanced Data Protection. Price and capacity pull in opposite directions after that: $0.99 buys 50 GB at Apple, while Icedrive's entry plan is 2,000 GB for $9.99.

Our picks

  • Encryption you never have to switch on: Proton Drive. All files are encrypted by default, free tier included, and $3.99 a month buys 200 GB under Swiss law.
  • The most room without paying: MEGA. 20 GB free, with the same zero-knowledge encryption as its paid plans.
  • A budget plan billed in euros: Filen. €1.99 a month for 200 GiB, with every file encrypted by default and a 10 GiB free tier.
  • Confidential work files under Swiss law: Tresorit. Run from Zurich under Swiss law, with zero-knowledge encryption on everything, from $4.75 a month for 50 GB.
  • A household that is all Apple devices: Apple iCloud+. $0.99 a month for 50 GB, with iCloud Drive, Photos and backups covered once Advanced Data Protection is on.

Whole-account encryption or an encrypted folder

pCloud is the row most likely to surprise someone searching this topic: its ordinary storage is not end-to-end encrypted. Client-side encryption comes from pCloud Encryption, sold on top of a storage plan, which activates a separate Crypto folder. Icedrive works the same way with its own Crypto space, which is listed as included only on paid plans, and its camera auto-upload sits outside it.

Apple iCloud+ covers much more once Advanced Data Protection is on, 25 categories including iCloud Drive, Photos and device backups, but the setting is off unless you turn it on. If you would rather not remember any of that, Proton Drive, Sync.com, MEGA, Tresorit, Filen and Internxt all encrypt the whole account from the start.

Reading the price next to the storage

Sorted by price alone, Apple comes first and Icedrive last, which says nothing about value. Among the fully encrypted services, Sync.com's $3.50 buys 150 GB, while MEGA and Proton Drive give 200 GB for under 50 cents more. Tresorit charges $4.75 for 50 GB, the least storage per dollar on the table, and is priced for compliance rather than capacity. Internxt's paid plans start at 1,000 GB and bundle a VPN and antivirus, so it is sold as a privacy suite more than a drive.

The billing basis differs too. Proton, Sync and MEGA are shown at their annual-billing rates. pCloud's $4.99 and Icedrive's $9.99 are month-to-month, and paying yearly brings them down to $49.99 and $99 a year.

Which country's law covers your files

Three of these are Swiss: Proton Drive, Tresorit and pCloud. Sync.com's privacy commitments are written around Canada's PIPEDA, Filen is German, Internxt is in Valencia under Spanish law, Icedrive is in Gibraltar, and Apple stores data in the United States. MEGA is the complicated one: its head office is now in Csomád, Hungary, alongside its Auckland operation, and its privacy policy says the governing law depends on which MEGA entity your agreement is with.

The options in detail

Proton Drive

Cloud storage from the Swiss company behind Proton Mail, started in 2014 by scientists who met at CERN. Everything you upload is end-to-end encrypted by default, including on the free 5 GB tier, and the cheapest paid plan gives 200 GB at a price in line with ordinary cloud storage rather than a privacy premium. It is the easiest pick if you want encryption you never have to think about, because there is no separate vault to remember to move files into. The catch is that the cheap tier is storage only: the plans that bundle Proton Mail, VPN and Pass cost several times more.

Sync.com

A Toronto company that has offered zero-knowledge storage for years, with end-to-end encryption covering the whole account rather than one special folder. Its cheapest paid plan is the smallest here at 150 GB, but it is also among the cheapest, and the free 5 GB account keeps the same encryption as the paid ones. Sync has tilted toward business use: its main pricing page now leads with Teams plans and you have to switch tabs to see personal ones. Its privacy commitments are written around Canada's PIPEDA rather than European or Swiss law, which is worth weighing if jurisdiction is why you are shopping.

MEGA

MEGA gives away the most storage of anything here: 20 GB free, with the same zero-knowledge encryption as its paid plans, so files are encrypted on your device before they upload. Paid plans start at 200 GB and also come with a monthly transfer allowance, which is unusual, since most rivals meter only storage. The wrinkle is jurisdiction: MEGA's head office is now in Csomád, Hungary alongside its long-standing Auckland operation, and its privacy policy says which country's law governs you depends on which MEGA entity your agreement is with.

Tresorit

The compliance-minded option, aimed at people and firms handling confidential documents, run by Tresorit AG in Zurich under Swiss law. Everything is end-to-end encrypted with zero knowledge, and the free 3 GB Basic account is a real ongoing plan rather than a trial with a clock on it. It is by some distance the most expensive storage per gigabyte in this table: the entry personal plan is 50 GB, a fraction of what MEGA or Proton hand over for less money. Pick it when Swiss jurisdiction, audits and business controls matter more than how much you get for the money.

Filen

A small German provider that built its entire product around zero-knowledge end-to-end encryption, with encrypted notes and chat sitting alongside file storage. It is the cheapest per gigabyte of anything here, at €1.99 a month for 200 GiB, and its free Starter tier hands over 10 GiB outright rather than as a trial. Two caveats. Filen publishes prices only in euros, so there is no dollar figure in the Price column for it. And it is a far smaller operation than Proton or MEGA, which is worth thinking about if you want the company holding your archive to still exist in ten years.

Internxt

A Valencia-based service governed by Spanish law, and the one here that markets post-quantum cryptography alongside conventional zero-knowledge AES-256, encrypting files on your device before they leave it. Its paid plans now start at 1 TB and bundle a VPN and antivirus rather than selling storage on its own, so it is priced as a privacy suite more than as a drive. The free tier is 1 GB, which is really only enough to try it. No price is listed in the table because at the time of writing Internxt's own pricing page renders its figures without a decimal point.

pCloud

Swiss-based and best known for lifetime plans, where you pay once instead of subscribing. It is also the row most likely to surprise someone searching for encrypted storage, because ordinary pCloud storage is not end-to-end encrypted. Client-side encryption comes from pCloud Encryption, which you switch on to activate a separate Crypto folder, and it is sold on top of a storage plan rather than included in it. The base 500 GB plan is priced competitively and the free account goes up to 10 GB, so pCloud makes sense if you want a large ordinary drive plus a vault for the handful of files that need one.

Icedrive

A Gibraltar company that stands out for using the Twofish cipher rather than AES for its client-side encryption. Like pCloud, the encryption is not account-wide: a separate Crypto space is what gets end-to-end encrypted, it is listed as included only on paid plans, and its own feature table marks camera auto-upload as sitting outside it. What Icedrive does give you is room. Its cheapest paid plan is 2 TB, roughly ten times the first tier at Proton or Sync, and the free account is 10 GB. The monthly price is correspondingly higher, so it suits people with a lot to store rather than a little.

Apple iCloud+

The service most people already have, and it belongs on this list only once you turn on Advanced Data Protection, an optional setting that raises the number of end-to-end encrypted iCloud categories to 25, covering iCloud Drive, Photos and device backups. At 99 cents a month for 50 GB it is the cheapest paid entry here, and the 5 GB free tier comes with any Apple account. Three things to weigh: Apple stores data in the United States, the protection is off unless you deliberately enable it, and it only really makes sense if your devices are all Apple.

How we researched this

We kept pCloud, Icedrive and Apple iCloud+ on the list even though they do not encrypt everything, because many people searching this already use one of them and assume they are covered; the Encryption Coverage column says exactly how far each goes. Prices, storage sizes and encryption coverage were read on each provider's own site, and so was jurisdiction, except in two cells that cite Apple's and Sync's privacy policies. Encrypted-storage roundups that promote their own house brand were not used as sources.

NordLocker was left out because its $2.99 a month is a first-year rate that renews at $59.88 a year, which would not compare with standing prices. Cryptomator was left out because it encrypts files you store elsewhere rather than storing them itself. SpiderOak, Skiff, Koofr and Ente came up as candidates but were not researched far enough to include. Two prices are blank: Filen publishes only in euros, so its €1.99 sits in its summary, and Internxt's pricing page displayed its figures without a decimal point in September 2026. Tresorit's $4.75 is the default figure on its page, and we could not confirm whether it is the monthly or yearly rate. Promotional banners come and go on these pages, and the total at checkout is the figure that counts.
