Why you shouldn't send email attachments

Dangers of Attachments

share post

Every second more than 2 million emails are sent around the world. Often with important files, documents and letters attached. These attachments reach inboxes through few security controls, and hackers often use them as a gateway to companies' corporate systems. With the General Data Protection Regulation (GDPR), questions arise about the transmission of data in this way and the risk that this may pose to your company's duty to protect personal data, both of your clients and of your workers.

uncontrollable attachments

The moment you hit “Send” on an email, you lose control of it and everything attached to it, forever. Documents can be downloaded, copied, shared, and re-downloaded over and over again, which is an even bigger problem if the communication lands in the wrong inbox. The document goes from being on one device to being on at least two devices, and the inboxes of both the sender and the recipients.

Security, or lack thereof...

It is undeniable that emails are not secure enough to include sensitive and possibly confidential information in their attachments. They are vulnerable and you could incur liability for non-compliance with the GDPR. Currently, more than 80% of the volume of cyberattacks use email attachments as a means of attack.

Have you recieved my email?

It is common to send an email, and not know if it has been received, if it has been opened, if it has gone directly to the spam or junk folders, ... it is not always possible to know if your email has been opened, if the email has been seen attachment and who received it. If what you send is important and needs to be seen, it is vital that you know if and when it has been opened. Mistaking the recipient, or the wrong attachment, are one of the most common causes in terms of security breaches.

Employees look for workarounds for large files

Email attachments have a space limit, and if the file is larger than the limit, it cannot be sent. This can be easily avoided if you know the size limit of your company's server, but it's quite possible that the recipient of your email has a much lower limit and won't know that your important document has been blocked by their automated systems.

The alternative to sending attachments by email

It is true that sending the attached documents by email is easy. It is just as easy for cybercriminals, who can send massive emails with malicious files, hoping that an employee will click on it.

It is increasingly important for companies to have a secure channel for exchanging files, both to send them and avoid information leaks, and to receive them, where they go through much more advanced security filters than traditional mail.

Tranxfer helps secure the sending and receiving of documentation, scans all incoming documents, and analyzes outgoing ones through a DLP module to prevent information leaks.
