Most Secure Cloud Storage Companies in 2024

Jan 22 2024 - Category: Compare Cloud Storage

Taking extra steps to protect your data may seem like an unnecessary chore, since most people haven’t had a catastrophic data breach (that they know of). But loosing, or even worse, someone getting a hold of you confidential information will show you just how valuable your data is.

We are accumulating data faster than we ever have before, and as a result, data breaches are becoming more common. Securing data is becoming increasingly difficult, but thankfully, some cloud storage companies are taking cloud security to new levels.


What Makes Cloud Storage More Secure?


  • End-to-End Encryption – Don’t just encrypt your data at rest, but just as important, data should be encrypted in transit.
  • Zero-Knowledge Encryption – Only you have the key to decrypt your data. The storage provider is not capable of viewing your data, not even if a court orders them to do so.
  • Multi-Factor Authentication – Having only one type of password leaves you vulnerable to password theft and brute force attacks.
  • Redundancy – Data is copied to multiple servers in different geographical locations.
  • Physical Security – Securing the data center from intruders, and more importantly, insider threats.

By evaluating cloud storage providers using theses metrics, as well as there past performance, we are able to figure out who has the most secure cloud storage.

#1 – NextCloud


NextCloud is the most secure cloud storage, but its not the simplest solution. NextCloud is your own personal cloud. It is just the software, you provide the hardware. So you can put it on your own server, or paid server hosting. This may sound complicated, and it can be, but there are plenty of hosting companies (eg. Linode, A2Hosting) that have options with NextCloud preloaded, which makes getting started very easy. NextCloud is free and opens source software which gives it the added assurance that the software is sound, since available for anyone to see, unlike proprietary software, where you just have to hope that it was built right.
