How Emailing Private Docs Can Leave You Vulnerable

In 2019 alone, hackers exposed 7.9 billion records in 5,183 data breaches.

While threats to data security come in many forms, transmitting sensitive data over the internet can leave you open to some serious vulnerabilities.

When it comes to sending the most important documents, many businesses still rely on the trusted security of traditional fax. But the high cost of maintaining separate phone lines, hardware maintenance, and supplies convince many businesses to opt for paperless options.

Both email and cloud fax offer potential solutions for sending secure documents, though there are inherent flaws to email security which can leave your sensitive data exposed.


Why Email Security Won't Cut It

While many companies trust email for internal and external communications, most providers don’t offer the elevated level of security required for many regulated industries.

To avoid exposing sensitive information to hackers, you must understand the problem inherent with sending your files as email attachments.

The first problem with many email systems comes when users log in. While some providers offer two-factor authentication to prevent fraudulent logins, many people don’t opt-in to this feature. As a result, hackers only need the username and password to access everything in the user's email. In fact, stolen passwords appear quite frequently on the dark web. Since 2017, 555 million passwords have been stolen from unsuspecting users and posted.

The second problem with email security comes from its lack of encryption.

Most email programs do not encrypt messages or attachments. Any breach into the email system exposes all the information in both the attachments and the text of emails to anyone who can gain account access.

Third, if you don’t have a read-receipt option for your email system, you can’t know whether the recipient has actually received and opened your emails. In fact, one small mistype in the address could send a sensitive document to the wrong person, leaving you unsure if your message ever reached its intended destination.

Lastly, email requires users to print out attachments, sign, scan, and reattach them to a new email for return. This process is both time-consuming and harmful to the environment (what a waste of paper!).

Additionally, the scanned signature on the email may not be acceptable in some industries that require authenticated forms. Digital signatures that offer authentication of the user and document are a better option in these cases. This enables you to send documents for a recipient to sign digitally using a secure cloud fax service.


Cloud Fax - The Best of Both Worlds

While email might work well for fast communication, it doesn’t necessarily work in situations requiring the highest security for documents.

Medical, legal, financial, and government-related companies require a highly secure method of sending documents. Traditionally, these industries have relied on fax machines for this purpose because the analog nature of faxes doesn’t have any openings for hackers to get access to information.

Unlike emails, cloud fax provides protection for every document sent through encryption both during transmission and while the document sits in the cloud.

Secure cloud storage relies on remote servers guarded with high-level physical security and redundant features to enhance reliability. During transmission, encrypted faxes stored in the cloud travel through servers in facilities with SSAE16 Type II security to reach their destination securely.

Companies that require the ease of email can use an email-to-fax option that allows faxing emails with the same level of security offered by cloud fax. While traditional fax machines print out receipts of the transmission, cloud services produce an audit trail of all document transmissions including the IP addresses and user information of those who login to the system. This audit trail is an essential component for businesses that require HIPAA compliance or for those who require similar document tracing capabilities.

Encryption during transmission and while on servers protects the information in any faxed documents from unauthorized access. mFax users have access to admin controls that allow admin users to dictate roles and permissions for all other users in the system.

When sending traditional paper faxes, another fax machine must pick up the line and receive the document for it to go through.

HIPAA-compliant fax systems must restrict access to sensitive faxes and have proper protocols for preventing a user from sending a sensitive fax to the wrong destination.

However, paper faxes can sit on a machine in an open office for hours or days until the intended recipient finally retrieves them, exposing the information to anyone else using the machine or even to people just walking by.

Electronic faxes increase security by only permitting those with authorization to access the digitally submitted faxes. With audit trails built in, you can quickly find out where any fax went, preventing faxes from missing their destinations.

While email services leave messages open to unauthorized access when a person stays logged into their account and leaves their computer, the same is not true of cloud faxes. mFax contains an automated log-off feature that prevents idle time from turning into an accidental security breach. User authentication and administrative controls over who can access files in the system also helps to reduce the chance that hackers using a stolen password can gain access to the server.


Cloud Fax Or Email?

So which is the better choice for secure document transmission?

While email is an easy and convenient way to send messages, it lacks many of the necessary security features essential for regulated businesses and those dealing with sensitive information.

Cloud fax provides high level encryption, server security, traceable audit trails, and strict user controls to prevent unauthorized access and ensure document security.

With fax to email options, cloud fax offers the best of both worlds - secure, compliant, and reliable document transmission with all the convenience and ease of sending an email.
