Secure file storage in Europe

Security is our top priority: security of data, which is transferred several times to different data centres, but also security of exchanges. We use SSL with an RGS certificate, which is the best in France (and costs us a fortune, mind you).

Try it now.


With Ziplo, we're offering to keep your documents for up to 15 years, so naturally we made sure our storage solution stood up to the test.


Our servers are all based in mainland France and are upgraded 3 times a year. This means that your file is written in 3 different places so that it can be found even if one hard drive fails. If one of the datacentres catches fire or floods, if a server breaks down or has any problems at all, we will always be able to recover your files without them being altered.


We also use an OpenStack solution that has been proven by a number of companies that are experts in cloud storage. This also means that we can change storage provider very easily (almost at the click of a button) should the need arise and for any reason that does not respect our commitments in terms of hosting, security or data privacy.

On Ziplo, we take care not to store files with public access. First of all, files are encrypted (we make them unreadable without a security key), we change their name for storage (so that no one can find out what a particular file is, even for the Ziplo team), we create a unique numerical fingerprint of the file (called a checksum) that we can use to identify the file; This is then checked to ensure that it has not been tampered with; ré then we store them on private cloud instances that are not accessible from outside the Ziplo cosystème.  

As ça, no one will be able to read your documents that you want to protect, unless you are the one sharing them with Ziplo!!

On the certificate we send you when you deposit your document, there is a digital signature of your file and timestamp information. This digital signature is self-contained and can be decrypted by anyone, without even using Ziplo (provided they know the correct mathematical formula!). Additionally, we have provided a page (verify a Ziplo digital signature) that allows you to enter this signature and decrypt its entire content.

In this signature, you'll find the following information:

  • the file name, its size, and a unique identifier
  • the digital fingerprint of the file (checksum)
  • the depositor's information (first name, last name, and email address)
  • the date and time of the deposit on Ziplo
  • the file's expiration date in Ziplo

In addition to this, in your Ziplo personal space, you'll find your deposit certificate (which we also send to you via email), containing certain information about your deposit, the digital signature mentioned earlier, and a QR Code that allows access to a page containing all the information related to your Ziplo deposit.

You can also retrieve the timestamp certification file for your deposit. Certified timestamping is the indisputable proof of registering your file on the platform and, therefore, proof of ownership.

The QR Code allows anyone to easily verify the information related to your file deposited on Ziplo. All you need to do is scan it to instantly access all the information that proves your deposit and can be used in legal matters. This way, you can verify the information and the deposit yourself. Others can do so as well when necessary: judges, judicial experts, bailiffs, notaries, lawyers, and more. For example, you can protect a blog article and display the QR Code at the end to indicate that you've protected it with Ziplo and that reproduction is not authorized.
