Between customers and employees, companies transfer thousands of data every day. Even the average Internet user sends data more than once a day. As cyber attacks become more dangerous, frequent and sophisticated, it is essential to learn how to secure data in transit.

This article will go over the best ways to send data safely.

Email encryption

Since most corporate communications are done via email, encrypting these messages is critical to organizational security. Personal communication via email tends to be more sensitive than other methods such as text or social media.

By default, most email platforms such as Gmail or Outlook are encrypted. However, emails are stored in plain text, which can be difficult if, for example, email providers suffer data breaches. That’s why it’s best to enable end-to-end encryption. S / MIME and OpenPGP are the two main email encryption protocols. You can enable them in your email provider settings

Virtual Private Network (VPN)

Using a VPN is one of the easiest ways to send data securely while browsing the Internet. A VPN will encrypt all your data traffic by funneling through a third server. This will hide your IP address and geolocation, making you much less vulnerable to external attacks.

Note that a VPN will not encrypt messages like emails or SMS directly. It will only hide the source, not the plain text. You still need to enable encryption to send messages securely.

Encrypted Cloud Data Storage

Many businesses are turning to the cloud to store large amounts of data. A good cloud storage solution is not only a convenient option for large data centers. This is a great way to send data securely within an organization.

More complex cloud solutions provide the ability to create, share and download files. Communications will be end-to-end encrypted, meaning no one outside the organization will be able to access the data. It is also very difficult to hack an organization’s cloud server, because there are many security measures to overcome it.

Secure File Transfer Protocol (SFTP)

Most people are familiar with FTP. This is the traditional protocol for sharing files on the Internet. SFTP is a new option that adds a layer of security when transferring files. SFTP protects data from external entities by encrypting with SSH (secure shell).

SFTP is available in the public cloud solution. You can also enable it on a private network Businesses must move to SFTP, as it does nothing to protect traditional FTP files in transit. Even amateur hackers can easily block FTP transfers. You can’t take that risk if you transfer sensitive data, especially since it can cost your business integrity.

Website data encryption

Websites may also contain data that needs to be safely removed. This is especially true for e-commerce websites that place sensitive financial data on their customers. All websites must use HTTPS to encrypt personally identifiable information. HTTP (Hypertext Transfer Protocol) transfers data to plain text, making it readable for anyone.

HTTPS runs HTTP via the Transport Layer Security (TLS) protocol. TLS is a newer version of SSL (Secure Sockets Layer), but the two terms are used interchangeably. In fact, more and more people are familiar with the SSL certificate used to encrypt website traffic.

Peer-to-peer (P2P) data transfer

For smaller groups, there is nothing safer than transferring P2P files. In P2P communication, the devices do not go through a central server to connect. Instead, they connect to a shared network and perform transactions through their personal network.

Since there is no need to involve a third party in a transaction, P2P is a highly secure method and is widely used for making payments. Over the past decade, P2P has been used to manage and communicate projects from a transaction protocol.

Near-field communication (NFC)

NFC is the safest way to exchange small files like images between two devices. NFC may not be as popular as Bluetooth, but it is still available on all modern smartphones.

NFC transfer is slow, so it is not ideal for large files. This is why it has lost its popularity over the years. However, it is much safer than using a USB, even Bluetooth, which is more powerful but more dangerous.


Whether you are a business or an individual, the data you send and receive wants to be private There are several ways to secure your data in transit. The security method you choose will depend on the method of your communication.
