Top secure cloud storage and backup compared

About Top secure cloud storage and backup compared

Secure cloud storage and backup services promise much the same thing and price it very differently. This ranking covers 70 of them, and the main trade-off is the gap between what you pay to get in and what you keep paying once the plan rolls over. The entry price in this category has a median of €4.99, while the yearly cost per terabyte has a median of €82.87 and runs €10.52 to €921.69 across the wider data. 86.5% of the members here include a free plan, with free storage at a median of 5. Provider-blind encryption, which leaves stored files unreadable to the company holding them, is close to standard here, with 76.5% of the members using it. That narrows the decision to price at entry, price at renewal, what the plan includes, and the country the account is registered in.

How we picked

Every service in this ranking is scored on the same set of criteria. Cost carries a weight of 40%, offer carries 40% and trust carries 20%. Cost looks at what a plan costs and what a terabyte costs over a year, so an attractive entry price is not enough on its own. Offer looks at how much storage the free plan includes, what the paid plan adds and how the plan model is built. Trust looks at where the company is registered, which law governs the account, whether files are encrypted so the provider cannot read them, and which certifications are listed. The figures come from each company’s own product pages, terms and support documents, alongside the comparison data behind the site. Cost and offer together count for more than trust, which lets a smaller service with a generous free tier and a clear yearly price outrank a larger brand. No payment changes a score, and any partner would be listed ahead of the scored members rather than given a place on merit. Where members share a service name but sit under different legal entities, each appears and is judged on its own registration and pricing.

Our top picks

1. 4. Acronis

   Acronis is in this ranking for backup depth and paperwork. The paid plan works out to $56.99 a year per terabyte, the free plan includes 50, the company is registered in CH as Acronis International GmbH, and support runs on phone, email and chat, including phone and live chat. The compliance list, ISO/IEC 27000 series, ISO 9001 and SOC 2, is the longest here, which matters when a client asks for a certificate. The cost is the price line, well above the services near the top of this ranking. IDrive, ranked next in this ranking, answers with a cheaper range, $12 to $23.98 a year per terabyte, provider-blind encryption and 10 free.

   • Free storage: 50
   • Price per TB per year: $56.99
   • Jurisdiction: CH

   Pros

   • Free storage of 50 outstrips MEGA at 20 and Degoo at 20, and Apple Inc. at 5.
   • Storage per terabyte of $56.99 sits under the encrypted storage group figure of €82.87.
   • Support covers phone, email and chat, and phone and chat lines are rarer in this field than help centres, which stand at 95.4% against 41.1% for phone.
   • The published compliance record, ISO/IEC 27000 series, ISO 9001 and SOC 2, is long enough for buyers who must show documented controls to a client or an auditor.

   Cons

   • Acronis has no free version, so buyers testing backup tools before paying should start with MEGA or Degoo, which publish 20 and 20 of free storage.
   • Per terabyte, Acronis ranks 11 of 31 brands in the group, so heavy storage buyers pay nearer the middle of the market for each unit.
   • A 5 device cap is tight for a family or small office, where encrypted storage rivals cover as many as 10 devices on a plan.

2. 5. IDrive Inc.

   IDrive sits in this ranking as the value backup option, with provider-blind encryption, 10 of free space and a paid plan that runs $12 to $23.98 a year per terabyte depending on the term. It is registered in US as IDrive Inc., support covers chat, email and phone, and the compliance page lists SOC 2 Type 2, SSAE 18 and ISO 27001 for anyone who needs paperwork. Mega Cloud Services Limited, the member ranked after it in this ranking, carries the same service name under a separate registration in NZ as MEGA Privacy (NZ) Limited, charging €15 a year per terabyte with 20 free.

   • Free storage: 10
   • Price per TB per year: $12 to $23.98
   • Zero-knowledge encryption: Yes

   Pros

   • Compliance statements list SOC 2 Type 2, SSAE 18 and ISO 27001, so a business buyer has named standards to check rather than a claim to take on trust.
   • Support runs on chat, email and phone, giving a reader both a live route and a written one when a restore stalls.
   • Encryption only the password holder can unlock: the terms answer yes, so the strongest privacy setting in this group is written into the contract rather than into a pitch.
   • The free allowance of 10 is above Apple Inc. at 5, so a free start is roomier than the bundle alternative.

   Cons

   • The free allowance of 10 is smaller than MEGA at 20 and Degoo at 20.
   • Free storage ranks position 8 of 36, so the free tier sits mid table while the paid rate leads the group.
   • The terms place IDrive Inc. under US jurisdiction at US, which counts against anyone who wants a non US legal home.
   • Fees per terabyte run $12 to $23.98 a year, so a large library pays the upper end of that range rather than the entry rate.

3. 7. Norton

   Norton appears in this ranking as a backup tool rather than a plain storage locker. Its plan model is listed as free, it runs under Gen Digital Inc. in US, and support covers phone, help centre and community, which includes a phone line for anyone restoring a failed machine. The company dates back to 1982, so the backup side is the reason it belongs in the list. With the model shown as free only, readers shopping on paid price per terabyte should look further down. Acronis, ranked next in this ranking, publishes a figure: $56.99 a year per terabyte, with 50 free on its free plan.

   • First-year price: $19.99
   • Renewal price: $59.99
   • Devices: 1 to 10

   Pros

   • Entry price of $19.99 for Norton Deluxe is well under the antivirus median of €49.95, and renewal at $59.99 still sits low.
   • One subscription covers 1 to 10 across Windows, macOS and Android and bundles vpn, password manager and parental controls that would otherwise be separate subscriptions.
   • A free version of the apps lets you try the security side before paying, with a free trial of 7 and a money back window of 60.
   • Support reaches phone, help centre and community, including phone, which is less common in the category.
   • The VPN has a no-logs audit by VerSprite, July 2025 (Technical Privacy Impact Assessment), a published third party review rather than a promise alone.

   Cons

   • Renewal sits well above entry: Norton Deluxe jumps from $19.99 to $59.99, and many antivirus plans renew under €3.97 a month.
   • The Norton Deluxe device allowance of 1 to 10 is behind the antivirus median of 10, while Apple covers more device types through iOS, iPadOS and macOS.
   • Support runs on phone, help centre and community, so help is by phone, help centre and community only.
   • Norton also lists standalone subscriptions: a VPN plan of $34.99 a month, a family plan at $49.99 a year and a password manager from $9.99.

4. 8. Proton AG

   Proton AG is in this ranking for its privacy record rather than its price, with a plan model listed as free and 5 on the free plan. What it offers is files the provider cannot read, a registration in CH as Proton AG, and GDPR, HIPAA and ISO 27001 for anyone who needs certificates. Support covers email, chat and help centre, including email and chat. Readers shopping mainly on paid allowance per terabyte will find cheaper figures near the top of this ranking. Icedrive, the member ranked after it, offers a paid plan running €22.25 to €29.50 a year per terabyte with 10 free and GDPR, UK GDPR and ISO 27001.

   • Devices: 10
   • Server countries: from 140
   • No-logs audit: Securitum, 2026

   Pros

   • No-logs claims are audited rather than asserted: Securitum's audit (Securitum, 2026) sits behind a No activity logs policy.
   • Free limits come with no caps on data or speed, no ads and no time limit.
   • 10 simultaneous devices, above the ranked VPN median of 8.
   • Servers in from 140 countries, with streaming for Netflix, Hulu and Disney+ and WireGuard and OpenVPN as the connection protocols.
   • A single account carries the VPN, a passkey vault with end-to-end encryption and 5 GB of free storage, with GDPR, HIPAA and ISO 27001 compliance reported.

   Cons

   • Support runs on email, chat and help centre, and there is no phone line among them.
   • The free plan limits put you on a single device at medium speed with randomly selected countries, so constant use points at a paid plan.
   • End-to-end encryption is marketed for Proton for Business, while the consumer plan encrypts only the connection from your device to Proton's servers.
   • The plan set is aimed at business buyers, so a home user ends up paying for features built around teams.

5. 10. Enpass

   Enpass earns its place in this ranking by pairing a free and paid plan model with provider-blind encryption and among the stronger compliance records in the list: ISO 27001, ISO 27701 and SOC 2, with the account governed by US. Support runs on help centre, community and email, so help comes from a help centre, an email address and a community. That suits readers who read privacy paperwork before they buy. Norton, ranked next in this ranking, has the opposite shape, a free model under Gen Digital Inc. in US with phone, help centre and community for support, so a phone conversation is available there and not in Enpass.

   • Price from: $1.99
   • Free plan: Yes
   • Platforms: Windows, MacOS, Linux, and 4 more

   Pros

   • A free plan exists and holds Up to 25 items in 1 vault, so a small vault costs nothing to keep.
   • Entry price $1.99 undercuts Total Password, which lists €9.99 at entry.
   • Vault data stays in the user's own cloud, so nothing readable rests on Enpass servers.
   • Apps cover Windows, macOS and Linux, so desktop, phone, watch and browser are all served.
   • Compliance spans ISO 27001, ISO 27701 and SOC 2, with an independent audit by security experts on record.

   Cons

   • Enpass is not open source, so outside researchers cannot read the code themselves.
   • Support runs on help centre, community and email, with no phone line or live chat in that list.
   • The free plan stops at Up to 25 items in 1 vault, so a larger vault needs a paid plan.
   • The family plan is billed annually rather than monthly, so families commit to a longer block.

What to look for

Entry price

Start with the cheapest way in rather than the headline. The entry price in this ranking has a median of €4.99, and a monthly figure with a median of €5.27 shows what the habit costs once it becomes routine.

Yearly cost per terabyte

Price per terabyte per year decides the long plans, because nearly everyone grows into the space. The median here is €82.87, well above the cheapest members, so compare the yearly figure and not just the first bill.

Free space

The free plan tells you how easy it is to try before paying anything. Free storage has a median of 5 in this ranking, and 86.5% of the members offer a free plan at all.

Privacy model and registration

Most services here encrypt files so the company cannot read them, with 76.5% of the members using that model. The legal entity and country behind the account decide who is bound by your data, and certification lists such as ISO 27001 and SOC 2 give business buyers something to check.

Support and reach

Support decides how fast a stuck restore gets solved. A help centre appears at 96.9% across this ranking, while community boards appear at 58.5%, and the server spread has a median of 5 countries.
