You can upload any file with Pcloud Drive using the web interface, mobile app, and desktop. PCloud gives only 10 GB of free cloud storage which is enough for home use, but not so much if you’re a big content creator.

Each file on the Pcloud server is encrypted with AES-256 bit before it leaves your device using an HTTPS certificate.

Features to look before picking cloud storage


Security is one of the first things to check when it comes to secure cloud storage. So your files are fully encrypted on the server. The server and your device combine their efforts to ensure all data is encrypted and decrypted as efficiently as possible.

This means that there is a possibility for an unauthorized person somewhere down the network path to see some of your files. So security is essential to check before picking the best cloud storage service. You must check what types of security encryption protocols they’re offering like does service support end-to-end encryption and what types of encryption algorithms they’re using to encrypt data.

Another thing you need to check is that they’re offering separate private encryption keys that are necessary for decrypting your files store in the cloud that enhance a more security layer of online backup.

Because only you can read and access files with a key. Hence, if somebody else manages to steal this key from you or otherwise obtains it, they will be able to read everything you have stored in the cloud storage provider.

Another most critical steps to keep your files secure is using unique, strong password protection for each service you sign up with and choosing a different password. This way, if someone gains access to that password, they will not access any of your other accounts. One other thing you can do is enable two-factor authentication in case your username and passwords are compromised somehow.

There are various methods for authenticating and verifying identities, and they include:

Tokens or One-time codes: Using tokens will generate a random number for each login, and this number frequently changes (sometimes every minute). This will make it more difficult for unauthorized people to access your account since they would not know the exact code, which might differ from one login attempt to another.

Biometric identification: This method can include a fingerprint scan. The advantage of this type of authentication is that it cannot be stolen or hacked, unlike passwords which we tend to write down or reuse on different websites or services.

Since some cloud storage providers offer more security than others, you need to research how the provider protects your information and if they comply with various international standards before deciding on the exemplary service for you.

Privacy Policy of Cloud Storage

When you’re going to sign up for one of the cloud storage providers, it is most important to read their privacy policy and then decide if that aligns with your preferences. For example, what information they’re collecting? Do they’re selling certain information about you to other companies or organizations without your permission? Or provide access to security agencies.

It is also a good idea to find out what kind of information they retain for themselves or delete after a certain amount of time. For example, does the provider hold on to your personal data indefinitely or until you ask them to delete it? And where their data centers are located.

Which cloud service is best for privacy? And which cloud is the most secure?

For organizations with sensitive data to store, point of sale, and back-end payment systems, the cloud is the securest choice. Pcloud stores files in data center around the world for redundancy and end customer file transactions every minute.
This means every backup is checked and continuously verified for consistency; even they store a copy of your backups in a different geographical location than your main on-site data center.

With privately encrypted storage at multiple locations, you can rest assured that your business can be rebuilt on new equipment or software, knowing that your backups are safe – always available, never lost!

Is cloud storage 100% secure?

Yes, it is 100% secure. Cloud storage should be considered safer for backup than the alternative because cloud companies provide features rich backup systems. And most cloud providers are excellent in security.

That offers high standard protection by using multi-layered access controls for firewalls and proxy configurations; encryption system such as 256-bit SSL (Secure Socket Layers); two-factor authorization such as Dual Authentication Scheme and other robust encryption protocols. On other hand, on local storage, you define your own security and privacy protocols.

Which cloud service is best for privacy?

Without any doubt and concern, Sync.com is the best cloud storage in terms of a privacy policy that complies with PIPE.

Can clouds be hacked?

Yes. The current fear around the IoT revolution is that hackers will break into “unsecure” third-party cloud storage providers and then use them as a gateway to hacking into sensitive data back-end servers hosted by third parties.

Clouds are just another type of networked device, one with virtually unlimited bandwidth and storage capacity, which means if someone can find your unsecured cloud server, they can easily exploit it for wicked purposes. Any home user who is using unsecured wireless network risks is a primary target of a hacker. 

How Safe Is Microsoft OneDrive?

Microsoft’s security and privacy policy is simple; it keeps all the information you upload to OneDrive private and doesn’t share it with anyone.
