4. Signal

Our expert review:

Open source, reviewed by peers, and run by donations and grants: these are just some of the characteristics of Signal, and they are also some of the good reasons why more people trust this messaging app as a form of file transfer solution. The open-source nature of its encryption engine makes it open for anyone to inspect and review for further development.

Encryption is a leader in the industry, but the whole interface is quite plain and basic in terms of its physical appearance. The visuals are plain and pretty direct. As a messaging app, it is quite useful with the availability of group chats as well as sharing photos and files.

You can also use Signal as the default messaging app, but there is no encryption on basic SMS service. Signal has to be installed for you and your contact for the encryption to work. The app also has some additional features like video calls and disappearing messages.

8. Tresorit

Our expert review:

A European cloud file storage company, Tresorit made itself popular when it challenged hackers to get into its servers for a price of $50,000. It claimed that no one succeeded in doing so. The company focuses on optimum security as it highlights its offers of end-to-end encryption in sharing and syncing files, compliance withGDPRand HIPAA, and being backed up by internationally-renowned privacy laws among other security measures. Customers in other countries have been offered recently with the option for data residency.

Tresorit comes with a wide selection of plans for personal, business, or enterprise use. It does have a free plan, but this is very limited to only 5GB of files for sharing and cannot be stored in. It offers a free trial, which lasts for 14 days only and requires credit card details upon registration, too. Additional features with the paid accounts include an admin console, branding, integration with Outlook, and “zero-knowledge” protection.

Best secure file transfer solution for simple syncing

9. SugarSync

Our expert review:

SugarSync comes with this sweet ability to simply right-click on the folder, and it gets synced right away as long as your SugarSync desktop application is ready. It also gives you the ability to create a designated folder on your computer for all the files that are sync to the service, which used to be automatically called Magic Briefcase but is now My SugarSync.

The biggest limitation of the service though is the lack of integrated third-party tools and even simply two-factor authentication beyondMicrosoftOutlook. There is also no actual free plan but only a free trial plan with 5GB only.

Many of these options have similar services and advantages, but some might work better for your file sharing and syncing needs. It is all up to you to determine which one suits you and your requirements best.

Secure file transfer solution FAQs

What is SFTP and why should you opt for one?

The world abounds in basic file transfer protocols (FTP). However, they are not the best option for you and your business. Organizations own files that contain highly confidential and sensitive information. When they are transmitted using basic FTP, there is no encryption or any similar strategy to conceal the information. As a result, it is available for anyone to intercept and access.

This is where SFTP or Secure File Transfer Protocol comes into the picture to save the day. Basically, this gives an additional layer of protection to keep your files from getting compromised. Your best option, therefore, is in the form of a secure file transfer solution with SFTP.

Before investing in any of the many file transfer solutions available online, you should take the time to evaluate each of the options you are considering according to certain characteristics.

The top consideration is security. Greater security is always better. No business wants its data to be compromised in any way. In order to do that, you should find a secure file transfer solution that comes with a complete set of security measures for protecting your information and keeping possible hackers away.

Compatibility is another important factor. Businesses do not use only one type of application daily. If your file transfer solution does not cater to all forms of data, you might end up losing a significant amount of data in the process. Therefore, you should opt for a solution that works across common protocols like FTP, FTPS, SFTP, and HTTPS at the very least.

The third, but definitely not less important, characteristic of the file transfer solution is its controllability. Representatives of the organization should be able to control who can be given access to the file and the transfer based on the need and the person’s role in the organization.

Which secure file transfer solution is best for you?

When deciding which secure file transfer solution to use, first consider what your actual needs are, as budget options may only provide basic features, so if you need to use advanced tools you may find a more expensive platform is better suited to you. Additionally, higher-end software can usually cater for every need, so do ensure you have a good idea of which features you think you may require from your secure file transfer solution.
