Storing your files in the cloud certainly is a delicate topic. Especially with recent news about the NSA scandal many people worry about storing their files online with an external provider because they don’t know exactly what happens to their data and who is able to access uploaded files (ideally only you, but who knows?).
Personally, I’m a fan of local encryption before sending anything into the cloud. I even do this with my favorite cloud storage service JustCloud. Of course not everybody once to take that extra step handling different encryption keys, thinking about what to encrypt and what to store online. However if you just stop for 10 minutes and think it through it is certainly worth it to encrypt your most important files and choose a secure cloud storage provider from our list of services that John and I recommend.
If you are unsure whether cloud storage is the right solution for your needs be sure to check out our guide on how to choose a cloud storage service and our cloud storage comparison chart where you can compare features and functions of all the major services online.
The tools that keep me safe
Many people email me asking which tools I use to keep my files safe. They must think that I’m using a lot of tools with very complicated settings. However, that is not the case and I will explain to you which services you might consider for secure cloud storage and how easy it is to set everything up for your needs.
JustCloud secure file storage
If you have read a couple of articles here at CloudStorageReviews.org you certainly know that JustCloud is our favorite cloud storage service that we recommend to friends and family. While they are good for everyday use and they are very cheap they do not offer local encryption of your files. So you have to take care about that yourself.
I personally don’t mind doing that, however, I can understand if people would like to avoid fiddling around with encryption software. Nevertheless, you should consider JustCloud as a primary on my backup and cloud storage service for the majority of your files and then combining it with another secure cloud storage service for files that are highly sensitive.
You can read my JustCloud review here.
The disadvantage of secure cloud storage providers is that they are generally more expensive than normal cloud storage services that only encrypt the connection between your computer and their servers. So you have to be willing to put in an extra coin if you like total privacy and anonymity.

SpiderOak file sync and cloud storage
When comes to secure cloud storage online SpiderOak is certainly a company worth looking at: they were among the first to put privacy and security first. The good thing is that you can get 2 GB of free. So if you have just a couple of important files that you want securely encrypted in the cloud that free version might be enough for you. If you need more space you can upgrade for $10 per month for 100 GB.
SpiderOak not only offers cloud storage, they also have a full-fledged online backup and file synchronization service included. That means you can program your computer backups automatically according to your schedule. Also file sharing and synchronization allows you to access your files from anywhere in the world on multiple devices. You can securely share folders or files with friends, family and colleagues.
Of course, that many features come with a downside: not every part of the software seems to be well thought through in comparison to other cloud storage services. Yet when it comes to security SpiderOak offers a so-called zero knowledge privacy which means that SpiderOak encrypts your files locally with your personal encryption key of your choosing which does not get transferred to SpiderOak.
On the other hand, that means you cannot restore your files if you lose that personal encryption key. Your files are fully encrypted and even if somebody from the NSA would like to spy on your files they wouldn’t be able to see the contents of your files.
SpiderOak offers a combination of a 2084 bit RSA and a 256 bit AES encryption method to keep your file secure. Let’s look at what SpiderOak says with regards to their encryption method:
Final note on SpiderOak
If you need or want to take your file encryption and security seriously you should certainly have a look at SpiderOak. The major advantage is that he contested for free and get 2 GB for life. You will have access to all the features and benefits. Please tell your opinion on SpiderOak and if you’re using it already would love to hear your thoughts!www.spideroak.com
We talked about Mega.co.nz in the past here at CloudStorageReviews.org when we compared it to other cloud file synchronization services like JustCloud and sugar sync. Mega.co.nz is certainly an interesting alternative because it provides users with 50 GB of storage space. There are Pro accounts available starting from €9.99/month or €99.99 per year for 500 GB if you need more space you can also opt for a 4 TB version. Now, what makes Mega are unique is that there is actually no desktop version available. You have to use it in the browser which can be an advantage but also a disadvantage. It makes it easy to use and OS compatible yet some would like to fine-tune it in a software client environment.
In terms of encryption Mega promises to be one of the most secure alternatives on the cloud storage market. Your data is encrypted before it is sent over the Internet to Mega’s servers and then decrypted when you download them. As with all highly secure cloud storage services that all depends on your security key. If you lose that you will not be able to access/restore your files.
Let’s see what mega has to offer in terms of encryption:
Final words about MEGA
So what’s the deal with mega? I think Megan is very useful if you have a couple of files the data you need to store online and only will access them via a browser. 50 GB of free is a nice touch, however, that is nothing that impresses me. Also, what is very interesting is that Mecca is very speedy offering one of the highest upload and download speeds available today.
Given the history of mega osprey and father Kit.com I’m still a little reluctant to use that particular service. Even though he has resigned as a CEO. As we can see, there have already been found several vulnerabilities, so no service is actually perfect as promised.
It’s going to be interesting what else made it has to offer in future. Megan wants to be a platform for other services like video sharing and streaming and photo storage. Let’s see what the future brings.Sign up for MEGA
Wuala works similar to SpiderOak, however they offer more flexible storage plans starting from $4 per month for 20 GB to $12 per month for 100 GB. So they are a bit more expensive than SpiderOak yet you can choose less storage if you need to.
Like SpiderOak, you have to create your own security password with Wuala to access your files and even get features like file versioning and file synchronization. You can also share files with the Wuala, yet those files can only be protected with a password so they are not encrypted when you share them with friends and family.
Their security and encryption process is similar to SpiderOak because they use an AES 256 encryption for transfers and an RSA 2048 that will be plenty for your files.
Final words on Wuala
My first impression of Wuala is quite positive. You can do all the things that you need when you think about a more secure cloud storage than, say, Dropbox. Even accessing your files from a mobile phone can be done with Wuala.
I need to test it a little more to come to a full conclusion, yet it seems like a worthy competitor to other cloud storage services that offer the same level of security.Sign up for Wuala
Doing it all on your own
Of course, you shouldn’t rule out the possibility to do all your cloud storage needs and encryption yourself. That way you can ensure that you are in full control of what happens to your data. Most of the time, this can’t be done with just a click of the button. So you need have little more patience. I think, however, that thinking about doing it yourself is a good alternative.
Using ownCloud for your cloud storage needs
If you want to know which are the best and most secure cloud storage services you should have a look at our regularly updated top 10 list of best cloud storage services. However, if you really want to do it on your own you should highly consider purchasing a network attached storage ([dic]NAS[/dic]) device and use it in combination with ownCloud.
If you use a network attached storage you have all the control you need for your sensitive files. I personally use a NAS from Synology with two 3 TB hard drives in it. Then I can install ownCloud from the packages menu and set up my own dropbox. Now, I could even go further and encrypt those files with Boxcryptor or Truecrypt.
I’m still working on a full tutorial on how to do that.
Should you use cloud storage?
I think if you don’t use cloud storage you’re missing out on some major features that will ease your life on a personal as well as on a business level. Cloud storage services give you access to all your files wherever you are. If you are very security concerned you should certainly keep the advice in this article in mind and use only secure cloud file storage services for your most sensitive information.
If budget is your concern you should certainly have a look at JustCloud, that I recommend to my friends and family for all the rough online backup and cloud storage needs. You can sign up for free here.
