Most Secure Cloud Storage  – 6 Bulletproof Solutions

People increasingly use cloud storage for businesses or personally, thanks to its convenience. When you upload sensitive documents to the cloud, the providers you entrust with them must be taking steps to keep them safe.
Cloud storage improves your resourcefulness with a guarantee that members of your team will always have access to the data they need no matter what. At the same time, the solution will back up your data on the cloud simultaneously to escape the catastrophic failures of your devices.

In this guide, we’re going to evaluate how secure is cloud storage and 6 of the most secure cloud storage solutions in the niche.

How Secure is Cloud Storage?

All data stored on secure cloud servers benefit from an enhanced grade of safety. The security credential most folks are familiar with is the password. Cloud storage security providers secure data using other resources also.

Some of them include:

  • Advanced firewalls – They control traveling data packets. Simple firewalls only inspect the source and destination data. Advanced ones verify package content integrity. These programs then map package contents to known security threats;
  • Intrusion detection – Online safe cloud storage can support many users at the same time. Top cloud security systems rely on identifying when someone tries to break into the system. Multiple levels of detection ensure cloud providers can even stop intruders who cut through the network’s initial defenses;
  • Event logging – Event logs assist security analysts in understanding threats and record network actions. Cyber security analysts apply this data to create a narrative concerning network events. It helps them predict and deter security breaches;
  • Internal firewalls – Not all accounts should have complete access to data stored in the cloud. Limiting secure cloud service access by internal firewalls improves security. It ensures that even a compromised account can’t gain full access;
  • Encryption – It keeps data safe from unauthorized users. If an intruder steals an encrypted file, access is denied without a secret key. The data is worthless to anyone who doesn’t have the key;
  • Physical security – Cloud server farms are highly secure. They have 24-hour monitoring, fingerprint locks, and armed guards. These centers are more reliable than almost all on-site data server farms. Different cloud providers use different approaches for each of these factors. For example, some cloud storage systems keep user encryption keys from their users, while others give the encryption keys to their users.

Security Risks

More than 35% of data security breaches occur due to employee error. Therefore, improved user security makes cloud storage more secure.

Many elements contribute to user security in the cloud storage platform, including:

  • Authentication – Weak passwords are the most common security vulnerability. Many employees write their passwords on paper. It defeats the purpose. Multi-factor authentication can solve this issue;
  • Awareness – In the modern environment, every job is a cybersecurity one. Staff must know why security is so important and be trained in security awareness. You must know how hackers break into the system. Also, you must prepare responses to the most common attack vectors;
  • Phishing protection – Phishing frauds remain the most used cyber-attack These strikes attempt to compromise your passwords and emails. Then, culprits can move through business systems to obtain access to more sensitive data;
  • Breach simulation – Simulating data breaches helps employees identify and prevent phishing attacks. You can also improve response times when real breaches happen. It establishes protocols for handling the suspicious activity and gives feedback to users.
  • Measurement – The results of the data leak simulation should inform future performance. Practice only becomes perfect if analysts measure the results and discover ways to improve upon them.

Which is Most Secure Cloud Storage for Business?

There’s no such solution as one-size-fits-all cloud storage. Plus, not all cloud storage solutions are created equally. You need to know that you are safe, secure, and good to go with an ultimate solution you can rely on.

Read our checklist before you decide what your first pick is.

1. pCloud – Best Free Encrypted Cloud Storage

pCloud approaches security differently that many vendors. Instead of encrypting all data before sending them to the server, the company asks you to decide between those that should be coded and those that shouldn’t. These are cases in which you wouldn’t want your files to be encrypted, like when you’re uploading images, you might need to browse later.

This cloud solution goes a step further in guarding the files locally. If you signify a file “confidential” by moving it into the pCloud Crypto (costs extra) folder – it’ll be coded.

pCloud – Best Free Encrypted Cloud Storage

The platform allows you to lock your encrypted files locally, which is excellent if you need to share your computer. It also protects those files if your PC is lost or stolen. The data are only encoded when you enter your key, and they can be easily locked by clicking a button.

Every pCloud account includes the most advanced 256-bit encryption from the moment you upload the folders. Plus, it saves 5 copies of all your files on different servers, adding an extra level of protection to your data.

As an alternative to a monthly or annual subscription, you can have one payment of $175 or $350 for a lifetime subscription. You can opt for a free plan which offers you 10GB of space.


  • Data is secured/backed up on 3 servers;
  • Lifetime plans;
  • Easy access to your data;
  • Convenient file management on the go;
  • Locally encrypted secure capability;
  • 10GB free online storage.


  • Some features aren’t available in the free model.

2. Tresorit

Tresorit is a cloud storage system that claims to offer a “100% secure cloud storage service.” Security trademarks include client-side encryption, secure data centers that are armed with physical security measures against intrusion along with uninterruptible power and backup platforms.

It encrypts the files on your local machine to ensure that your data are protected at all times. This system also practices a zero-knowledge password policy, which means that nobody in the company can ever access your decryption keys or password.


However, the downside of such a policy is that if you forget the password, you’re virtually out of luck (you’ll need to create a new account, and you’ll lose all of the data in the cloud).

Its chief difference from traditional cloud storage services is the capacity to turn any folder on your computer into a secure “tresor.” It means that you don’t have to drag and drop files into a particular sync folder; just right-click on an existing folder and “tresor it.” This’s a great option if you’re digitally organized and want to avoid prearranging your files into one sync-able folder.

The vendor offers 5GB of space for free, while an additional 100GB will cost you $7 per month.


  • Zero-knowledge and client-side encryption;
  • Data are secure and easily accessed from anywhere;
  • Sharing and collaboration are still possible without sacrificing security;
  • Permitted device list;
  • Great platform support;
  • Fully-equipped interface.


  • Limited free storage.

3. Sync

Sync applies end-to-end encryption to protect your data so that you’re the only one that can access them. But how is this different from other platforms?

Many other solutions can access, read, and scan your files also – Sync says that it can’t. Aside from defending your data, the solution has a strict privacy policy, and the vendor guarantees not to retain, sell, or share your personal info or use with third-parties, including advertisers.

It complies with global data privacy laws – so, no matter where you’re in the world, this system is safe to use. It has the USA and Canadian as well as EU and UK GDPR compliance built-into its system.


Besides the two-factor authentication and granular user permissions, the platform also has an enterprise-level infrastructure where it replicates data across different data center locations with SAS RAID storage.

Also, you can get this platform for free with 5GB of storage. However, if you choose the provider’s business plans – they range from $8 for individual subscriptions or between $5 and $15 per user depending on the storage space.


  • Global data privacy compliance;
  • Easy file restoration;
  • Files encrypted at rest and in transit;
  • Real-time backup;
  • Collaboration tools;
  • Excellent support team.

In lieu of storing meta-data from your files on the servers, it stores on your PC. Therefore, every time you change devices to access your files, the platform encrypts the metadata before it goes to a new device. This’s a great way to prevent ransomware and hackers from getting their hands on your data.

SpiderOak One Backup

SpiderOak gives you a high stratum of control over user groups due to its management console. As a team administrator, you can maintain folder creation and deletion along with user privileges.
