Sending secure email attachments in Gmail has become very important, but sending an encrypted email in Gmail without an encryption extension can present security vulnerabilities for the email recipient. Users don't realize how unsafe Gmail can be, and how the user's emails in transit can be intercepted by unethical third parties. With more than 1.5 billion active users worldwide, Google's Gmail currently dominates the email provider market and has grown leaps and bounds since its inception in 2004. Who doesn't have a Gmail address? And professionally, Google's G Suite service is utilized by more than 5 million companies, empowering businesses across countless industries to communicate, collaborate, and share important files, documents, etc. every day. In 2020, the Gmail platform is both frequented and beloved for the convenience and efficiency that it offers users.
Unfortunately, Gmail does not provide adequate data protection measures in their email service. By performing regular scans of user emails and gathering data to inform advertisers, Google ultimately puts users' utmost valuable and sensitive information in jeopardy. Although many users have come to brush this fact off, in some cases, deeming it a harmless, unavoidable part of technological life, emails in transit that don't utilize S/MIME encryption or transport level security can become intercepted by third parties with the potential to become leveraged for malicious purposes and phishing attacks. Although seamless and built-in, Gmail's S/MIME (Secure/Multipurpose Internet Mail Extensions) and TLS encryption options are lacking, only working correctly if both the sender and recipient are equipped with it. Without proper email encryption enabled, confidential attachments pertaining to business, financial, and even personal information might fall into the wrong hands. Thankfully, third-party encryption software is available to ensure the security of all attachments and messages transmitted.
Confidential Mode in Gmail
To boost email security offerings, Gmail rolled out its confidential mode option in 2018, allowing "users to send emails that recipients can't forward, copy, print, or download." Although the name of this security method evokes a sense of heightened data safety and confidentiality, in actuality, it effectively provides neither. With confidential mode enabled, users are also empowered to generate passcodes, activate message expiration dates, and rescind recipient access to specific emails. Thus, their confidential mode thwarts any sharing -- whether accidental or otherwise -- on the part of the email's recipient. And a recipient that intends to share an email's messages or attachments with unintended viewers is not prevented from doing so with ease via a simple screenshot. Furthermore, this security mode does not offer end-to-end encryption, permitting Gmail and additional providers to scan and collect email contents.
How to Encrypt Your Emails and Attachments In Gmail
So how do you send a secure email attachment in Gmail? The attachments shared via Gmail are often just as sensitive, or potentially more so than their corresponding messages. End-to-end encryption masterfully encrypts an email's contents while in flight and at rest, ridding emails of most security vulnerabilities. Undoubtedly, this makes end-to-end encryption the most secure method of Gmail encryption, as it protects the user's valuable messages, files, documents, etc. Although Google has often entertained the conversation around implementing end-to-end encryption, it has failed to do so as of yet. Gmail offers users a few added security options at a price. Still, to fill the void left behind by Google's Gmail, several third-party encryption services have stepped up to offer their own applications and extensions so users can properly send secure Gmail attachments.
Upgrade Your Gmail Account
In order to upgrade the data security which operates within your email account, one might consider upgrading their Gmail account from the free model to one of the platform's paid offerings. Both the G Suite Enterprise and G Suite Education plans provide S/MIME encryption. A step up from the standard TLS encryption provided by Google, which performs automatic encryption on all outgoing emails, S/MIME encryption enables users to encrypt emails with keys unique to the user and are required to be shared with the intended recipient. Users of either of Gmail's paid models can discern the level of encryption being employed by any given email.
With this being said, S/MIME encryption can only be successful if exercised by both the sender and the recipient. In other words, an email, even if sent utilizing S/MIME encryption, will remain unencrypted if the intended recipient uses an email provider free of encryption. And to top it off, S/MIME does not prevent Google's scanning of emails for advertising data collection.
Find Another Email Provider For Advanced File Encryption
For those transmitting highly sensitive, confidential, or classified data, Gmail might not be a suitable fit. Although creating and transitioning to a new email account can be burdensome, it may help to achieve the level of security that is necessitated by your business, personal affairs, etc. It is critical to be incredibly diligent when researching a new email provider to ensure that this switch will be permanent and provide the desired privacy and data protection. Along with end-to-end encryption, the most secure provider should offer guaranteed encryption, no matter the recipient's provider, as well as a zero-knowledge policy.
Use Gmail Encryption Software from Trustifi
Gmail attachments must be encrypted before being sent. By doing so, in the event that an email is intercepted and/or forwarded by a malicious actor, the attachments in Gmail will remain encrypted, rendering them useless to cybercriminals, hackers, and other third-party entities. However, discovering the most streamlined, user-friendly, and efficient method of email encryption does not have to be a daunting task. While the encryption solutions provided by Google seem to miss the mark and most third-party plug-ins are challenging to use, users who intend to stick with Gmail can seek the assistance of an encryption software provider.
