What 8 Arbolus experts think of Proton Drive

NPS scores are high: six of seven respondents scored 9 or 10, while one scored 6, producing an NPS of 71. Renewal intent is recorded as “Yes” for two respondents and is missing for five, so the available responses should not be treated as a representative renewal rate. Implementation-stage data show five respondents using the product for more than a year, one for less than a year, and one unsure. Qualitative feedback emphasizes privacy and secure storage, while identifying integration and Office autosave limitations as the primary drawbacks.Overall Customer Sentiment: Positive

What customers say

Privacy-led positioning
“I recommend the product primarily because Proton is committed to encrypting and protecting user data. I value its Swiss-based positioning and the respondent’s view that its privacy and cybersecurity standards are stringent. This is the clearest reason I would choose it over leading US-based storage brands. For an organization handling sensitive documents, the privacy promise is central to the product’s appeal, rather than an incidental feature. I would particularly consider it where secure cloud storage matters more than broad integrations with external business software.”
Shared access with controlled spaces
“I have seen a nonprofit use Drive as its primary storage space for multiple users. Its arrangement separates an organization-wide intranet space, accessible through the organization’s website, from a private database reserved for board members. I value that distinction because it supports shared organizational files while keeping a separate space for board material. The example demonstrates a practical multi-user setup with different access groups, rather than storage limited to an individual’s personal files.”
Flexible file storage and backup
“I use Proton Drive as a secure alternative for managing documents in the cloud. In my family-office context, I rely on it to back up and share files across an internal network. I can mount it to a computer in a way similar to familiar cloud drives, use it as a primary place to save documents, or keep it as a backup to another disk. That gives me more than one practical way to incorporate the service into file storage workflows.”
