Why You Should Not Send Confidential Information Over Email: Risks and Secure Alternatives

r

Sending confidential information via email has become a common practice, but doing so can expose your sensitive data to a myriad of security risks. In this article, we will explore the dangers of using email for confidential communications and provide you with secure alternatives to ensure the safety of your information.

The Risks of Sending Confidential Information via Email

r

When you send sensitive information via email, you are essentially leaving your data exposed to various risks. Here are some of the primary concerns:

r

Lack of Encryption

r

Many email services, including Google’s Gmail, do not automatically encrypt messages. This means that unauthorized individuals can intercept and read your emails without difficulty. Without encryption, your confidential data is vulnerable to being read and misused by anyone who can access your email.

r

Phishing Attacks

r

Emails can be spoofed or impersonated, leading to phishing attacks. In these attacks, cybercriminals trick users into providing sensitive information by mimicking legitimate email addresses or organizations. This data can then be used for malicious purposes, such as identity theft or financial fraud.

r

Misdelivery

r

Emails can be sent to the wrong recipient by mistake. This can lead to confidential information being revealed to unintended parties, such as competitors, criminals, or even individuals who are not authorized to access such information.

r

Storage Vulnerabilities

r

Emails can be stored on servers indefinitely, and these servers may be accessed by unauthorized personnel or during data breaches. Once your data is stored on a server, there is a risk that someone else may gain access to it, putting your confidentiality and privacy at risk.

r

Insecure Networks

r

Sending emails over public Wi-Fi or unsecured networks increases the risk of interception. In these environments, your emails can be easily monitored and potentially accessed by cybercriminals or other unauthorized individuals.

r

Compliance Issues

r

Many industries have regulations regarding the handling of confidential information. Examples include the Health Insurance Portability and Accountability Act (HIPAA) for health information and the General Data Protection Regulation (GDPR) for personal data. Sending sensitive data over email may violate these regulations, leading to legal and financial consequences for both individuals and companies.

r

Secure Alternatives

r

To protect confidential information, you should avoid using email and instead opt for secure communication methods. Here are some alternatives:

r

Secure File-Sharing Services

r

Secure file-sharing services such as Dropbox, Google Drive, or Box offer robust encryption and access controls to ensure that only authorized individuals can access your files. These services often have features such as two-factor authentication and granular permissions control, making them a safe choice for sharing sensitive information.

r

Encrypted Messaging Apps

r

Encrypted messaging apps like Signal, WhatsApp, or Telegram provide end-to-end encryption, ensuring that only the sender and intended recipient can read the messages. These apps do not store messages on servers, reducing the risk of unauthorized access.

r

Dedicated Secure Email Services

r

Dedicated secure email services like ProtonMail and Tutanota offer end-to-end encryption and strong security features. ProtonMail, for example, allows you to set expiration dates for messages and revoke access at any time. These services are designed to protect your confidential information from interception and unauthorized access.

r

Google Gmail’s Confidential Mode

r

Google’s Gmail does offer a feature called Confidential Mode that can provide an additional layer of protection. Here’s how it works:

r

Steps to Use Gmail’s Confidential Mode:

r rOpen Gmail on your web browser. rClick on the Compose button to start composing a new email. rAt the bottom right of the compose window, click on Turn on Confidential Mode. rSet an expiration date and passcode. These settings apply to both the message text and any attachments you include. r r

While Confidential Mode can help prevent recipients from accidentally sharing your email, it is important to note that it does not prevent recipients from taking screenshots or photos of your messages or attachments. Additionally, malicious programs on a recipient’s device may still be able to copy or download your messages or attachments.

r

Note: If you use Gmail with a work or school account, contact your admin to ensure you can use Confidential Mode.

r

Conclusion

r

While email continues to be a convenient tool for communication, it is not suitable for sending confidential information. The risks associated with email make it an insecure choice for sensitive data. By using secure file-sharing services, encrypted messaging apps, or dedicated secure email services, you can protect your confidential information from the myriad of security risks that come with email. If you must send confidential information via email, consider using Gmail’s Confidential Mode as a last resort, but remain vigilant about the full security implications.
