Hello HN friends,

My early-stage startup just left stealth mode to enter closed-beta. Our product, nCryptedCloud (which currently works with OSX 10.7+, Windows and iOS) is tackling the problem of data privacy and secure collaboration in the cloud. We're starting with Dropbox first, other cloud storage providers are in the plan.

nCryptedCloud is an enhancement layer on top of Dropbox. It encrypts & decrypts your Dropbox files seamlessly. Your files are always protected and you control who get access to them. For collaboration, you can revoke access to shared folders any time. Yes, even if they have the file, without permission, that file is not readable. Our purpose is protecting data at rest and data in the cloud.

Please give it a try if you have Dropbox installed. I would love any feedbacks you may have. Of course, it's free: http://ncryptedcloud.com/?rfc=VN-FRIENDS

Thank you,

The website should be as clear as this comment. I didn't really understand what the product did until I read this.

We will continue to improve the site and our messaging with feedbacks from wonderful folks like yourself!

Thank you,

How does your product compare to Dropbox+encfs or Dropbox+boxcryptor?

How about FileRock?

When we set out to create nCryptedCloud, we took a look at all the solutions out there. Some solutions address the private data quite nicely. However, the problem is secure collaboration. As far as I can tell, there's no way to easily share encrypted files with other people and this is one of the main problems nCryptedCloud solves.

Thank you for your feedbacks,

Enterprise is $10 per month for what, per enterprise? Really? No

If it's really enterprise, forget any price tag under $250, you won't be taken seriously. If it's not enterprise, call it Pro.

My apologies. $10 per user/per month for Enterprise version. This is fixed.

Thank you for letting us know,

Beautiful site. Is this Vuong's work? It's exceptional.

I can appreciate that you want your descriptions to be as accessible as possible, but I had trouble finding any technical details about your system. Do you have this information on your site? Is the source code available? If the answer to either of these is no, then I'd be extremely reluctant to trust you with anything important.

Also, am I correct in understanding that this is not a standalone service? Is this only usable with a dropbox?

Thank you for the nice complement. We're continuing to improve and iterate it. We're just focusing on producing the best software at the moment so our public-facing site can take a little bit to perfect. We welcome any suggestions you may have.

We understand that trust is an important issue and we're definitely in the business to solve this very problem. Our team members are probably the most paranoid bunch you'll ever meet. We worry about our own privacy in the cloud so we set out to build something we can use. All of us now religiously use nCryptedCloud to secure our own sensitive data in Dropbox.

At the moment, nCryptedCloud works with Dropbox but our plan is to work with other cloud storage providers as well. Which cloud storage provider do you use?

Is source code available? I couldn't find a link. Without the source, claims of privacy and security are very suspect.

We use standard & proven zip file format with AES 256 bit encryption. Each file has a unique key randomly generated. At this time, our source code is not available.

Thank you for your feedback,

Here's a litmus test: If a user loses their credentials, is their data unrecoverable?

Currently, the server maintains the backup key to recover data in case of lost/forgotten credentials. In the PRO version, users will be able to choose not to store this backup key on our server and will be responsible for maintaining it on their own; in this case data would not be recoverable without this backup key.

Thanks,

-V.

openbsd devs have the same thing called ciphertite except they have source review and you keep the key it can't be used by the corp to sell you out. didn't see any info about who controls keys

Looks good: https://www.cyphertite.com/

Can you securely share your data with this service? The reason I ask is because we're addressing this problem but at the same time addressing the difficult issue of secure collaboration in the cloud.

-V.

VuongN, you are indeed correct that you cannot currently share data with the service. this will change in the near future.

i had a look at your site, nice design :)

Thank you. Good luck to you guys. Consumer security is a difficult problem as you may already know. However, it is such a HUGE issue especially since most solutions out there give users an allusion of security. I think we got a very good product at the moment and would definitely continue to improve the user experience. Where are you guys? Come visit us some time :)

thanks for the plug guys =)
