Icedrive is a consumer-and-prosumer cloud storage service operated by ID Cloud Services Ltd, a UK micro-company based in Swansea, Wales (one secondary source additionally cites a Gibraltar company registration; the discrepancy is unresolved and flagged below). Founded in 2019, it is effectively a one-person operation led by CEO James Bressington, which is unusual for a directory of procurement-grade vendors and is itself a risk signal: there is no team depth, no funding disclosed, and no public corporate filings surfaced at audit.
The product's headline differentiator is encryption. Icedrive is the only mainstream cloud storage service to use the Twofish algorithm, and it offers true zero-knowledge client-side encryption: files and even file/folder names are encrypted on the device with a 256-bit key that never reaches Icedrive's servers. The important caveat for buyers: this applies only to files placed in a dedicated encrypted folder, not to the whole account. Anything stored outside that folder is not zero-knowledge.
For an EU-sovereignty audit Icedrive is weak. Storage is distributed across data centres in the UK, Germany and the United States with N+2 redundancy, and customers cannot choose their storage region, so EU data can and does land on US infrastructure, which is material CLOUD Act exposure regardless of the client-side encryption available on the opt-in folder. There is no public DPA, no sub-processors list, and no certifications. The vendor's own site (icedrive.net) returned HTTP 403 to automated fetching at audit, so several fields rely on secondary sources.
Pricing is competitive and lifetime-friendly: a 10 GB free tier, Pro plans from ~$5.99/month for 2 TB, and one-time lifetime plans starting around $389 for 2 TB with $199/1 TB and $449/5 TB add-on "stacks"; the lifetime model is the main reason Icedrive appears on best-of lists. Best fit: privacy-curious individuals who will discipline themselves to use the encrypted folder and who value lifetime pricing over EU data residency. Procurement-grade EU buyers should prefer Koofr (SI/DE), Internxt (ES), Tresorit (CH/HU) or Proton Drive (CH), all covered elsewhere on this directory.
