Is Cyphertite backup secure?

What is Cyphertite

Cyphertite is described, quite simply, as "high-security online backup." A quick browse of the provider's website seems to suggest this is an accurate description, and that this is a simple service best suited to techies and enthusiasts, rather than novices who require a little hand-holding. Cypertite's open-source roots are clear, with the website offering downloadable source code alongside complied client versions of the software. One benefit of this open-source approach is that Cyphertite's encryption methods can be "independently verified." Essentially, they set out to operate a

Cyphertite's free service offers up to 8GB of data. This is notably generous

What Features does Cyphertite have?

Cyphertite is a little light on features and doesn't try to be "all things to all people" like some other backup services.

In a way, it's easier to list what Cyphertite doesn't do than what it does! You won't find any friendly synchronization and sharing features here, and versioning is limited to configuring how many "increments" of a backed up file will be saved.

Also conspicuous by its absence is any mobile support - you won't find a way to access your Cyphertite files from iOS or Android.

One feature we've not found elsewhere is a Command Line Interface (CLI) option for controlling the software. Cyphertite does offer this, further extending its appeal to enthusiasts and experts.

What soon becomes clear when reviewing Cyphertite is that it's a classic secure online backup solution, aimed at a techie demographic and that it isn't really trying to be anything else.

Is Cyphertite Secure

Cyphertite begins to regain some lost ground when you look into privacy and security, as you would expect with a product where this is the focus.

Cyphertite operates encryption based on a "crypto passphrase" to encrypt data before it leaves your computer.

Another level of encryption is then applied once data reaches Cyphertite's servers. These are operated on a true "zero knowledge" basis, where even Cyphertite staff cannot access your data as they do not have your crypto passphrase.

Another thing that will please the privacy-conscious is that Cyphertite clearly lay our their attitude to handing over customer data to "the authorities." While they state that warrants can be served to force them to hand over customer data, they say that this will only ever be in its encrypted form, and thus only accessible by you, or anyone given your passphrase.

For those preoccupied with security, Cyphertite's lack of headline features may be adequately balanced out by these definite privacy plus points.

Other Platforms

As we mentioned earlier, Cyphertite doesn't offer any mobile device integration, so there's no Windows or Android client to review here.

It's also worth mentioning that while a version is in development, there is currently no Cyphertite software available for Mac, although Unix and Linux versions are available.


There's no getting away from the fact that Cyphertite is rather limited. It doesn't offer a fraction of the features of competing software, and the lack of Mac and mobile versions will put plenty of people off.

However, it would be a mistake to dismiss it out of hand. The stripped down, traditional approach to online backup will certainly appeal to a certain user demographic, as will the focus on privacy and security. If those things appeal to you, Cyphertite is worth a try, and it will cost you nothing to audition it.

    I'm pretty sure Cyphertite shut down mid 2015. This article is dated September, 2018. Did you do any actual research/review, or are you just recycling old news? Credibility... Zero.
