Email security refers to the collective methods, technologies, and best practices that help protect email accounts, content, and communication from unauthorized access, loss, or compromise. It encompasses measures to ensure the confidentiality, integrity, and availability of email data.
In today's digital world, email is a critical communication channel for personal and professional use. It's also a prime target for cybercriminals, who exploit email vulnerabilities to launch phishing attacks, spread malware, and steal sensitive information. In fact, 60% of small businesses close within six months of being hacked, which demonstrates the devastating impact of poor email security. Implementing strong email security practices is essential for safeguarding your personal data, business assets, and reputation.
In this updated guide, we outline the top 10 email security best practices to help you safeguard your personal and business communications.
Creating strong, unique passwords for your email accounts is the first line of defense against unauthorized access. Use a mix of uppercase and lowercase letters, numbers, and special characters to make your passwords difficult to guess or crack. Avoid using personal information, and never reuse passwords across multiple accounts. Consider using a reputable password manager to generate and store complex passwords securely.
Enable 2FA for your email accounts to add an extra layer of security. This requires users to provide a second form of identification, such as a fingerprint or a code sent to a mobile device, in addition to their password. With 2FA enabled, even if your password is compromised, attackers will have a harder time gaining access to your account.
Phishing attacks are becoming more sophisticated and difficult to detect. According to a Kaspersky phishing report, the number of phishing attacks doubled to reach over 500 million in 2022. Always scrutinize the sender's email address, the content, and any links or attachments in emails you receive. If something seems suspicious, do not click on links, open attachments, or provide any personal information. Instead, report the email as phishing or contact the sender through a known, trusted channel to verify its authenticity.
Encrypting your emails ensures that only intended recipients can read the message content. Virtru offers email encryption services that seamlessly integrate with popular email platforms like Gmail and Outlook, making it easy to protect sensitive information without disrupting your workflow. By using Virtru, you can confidently share sensitive data, knowing that it remains secure from unauthorized access.
Outdated software and operating systems can expose your devices to security vulnerabilities. Regularly update your email client, antivirus software, and operating system to ensure you have the latest security patches. Turn on automatic updates where possible to stay protected against emerging threats.
Create and enforce a comprehensive email security policy for your organization that outlines the best practices and protocols for email usage. As we highlighted in our blog about data security statistics, 53% of organizations have over 1,000 sensitive files open to every employee, and on average, every employee has access to 17 million files (Varonis). This underscores the importance of having a robust email security policy in place.
Your policy should include guidelines on password management, handling sensitive information, and how to identify and report potential phishing attacks. Regularly train employees to ensure they understand and follow these best practices.
Always connect to secure, password-protected Wi-Fi networks when accessing your email. Public Wi-Fi networks can be easily compromised, allowing attackers to intercept your email communications. If you must use a public Wi-Fi network, use a Virtual Private Network (VPN) to encrypt your connection and protect your data.
Regularly review and manage the access permissions of your email accounts. Remove access for users who no longer need it, and restrict the use of shared mailboxes. Implementing the principle of least privilege helps reduce the risk of unauthorized access to sensitive information.
In the event of a security breach, having a well-defined incident response plan can help minimize damage and ensure a swift recovery. Develop a plan that outlines the steps to take when a breach occurs, including how to detect, contain, and resolve the incident. Regularly test and update the plan to ensure its effectiveness.
Regularly backing up your email data helps ensure that you can recover critical information in the event of a cyberattack, accidental deletion, or system failure. Cloud storage services make it easy to backup, and for those with extra regulatory concerns, there's no excuse, as there are compliant services available. Use a secure, encrypted backup solution to protect your data, and periodically test your backups to confirm that they can be successfully restored.
By following the 10 email security best practices mentioned in this article, you can significantly minimize the risk of cyber threats and protect your personal and business communications.

Phishing emails often appear to be from legitimate sources but contain malicious links or attachments. Be cautious of emails with a sense of urgency, requests for sensitive information, poor grammar, or spelling errors. Additionally, verify the sender's email address and hover over links to check their legitimacy before clicking.
To secure your email on a mobile device, use strong and unique passwords, enable multi-factor authentication, update your device's operating system and apps regularly, and use a secure email app like Virtru's mobile application.
