Email continues to be one of the most significant malicious threats to organizations of all sizes. Attackers are constantly developing new methods to exploit email communication. Some of these include phishing, email attachment malware, and social engineering attacks. To address these risks, it’s important to implement a strong email security strategy that adapts to emerging threats.
Every organization must have an email security solution. However, there are some important best practices that every employee must know and follow. This way, they can help lower the possibility of a successful cyberattack.
Training your employees to be aware of email security threats and risks reduces your organization’s cyber risk. It also increases the chance of keeping your sensitive data where it belongs – with you, not the cybercriminals. With Mimecast, Security Awareness Training is not only efficient, it’s also fun and engaging.
Using strong, unique passwords for every account helps protect against unauthorized access. Encourage employees to create memorable passphrases instead of complex, hard-to-remember passwords.
Additionally, they should avoid password reuse to reduce the risk if one account is compromised. Regularly updating passwords and using password managers can help maintain email security practices.
2FA or MFA adds an extra layer of protection to boost your cybersecurity defenses. They ensure that malicious actors won’t get through, even if they manage to steal a user’s password.
This way, there will always be a second step that needs to be completed before a user can log into their email account. This could be, for example, a one-time password sent via text message or a unique code generated in an authentication application. Using a strong password is great, having 2FA or MFA in place is better.
Occasionally, we all get them – those predatory emails that pop up in our inbox alongside the legit ones. Some of them are so sophisticated, it’s hard to tell that they are phishing emails. Knowing what signs to look for is an essential part of keeping your organization safe from a phishing attack.
Keeping business and private email separate can help protect both your business and private information. Data breaches can happen to anyone at any given time. They can also lead to serious implications for businesses.
If your personal email is compromised in a data breach, attackers have a greater chance of gaining access to sensitive information. They can then use it to access your business email or network. By keeping business and private email separate, you mitigate the risk of a data breach spreading across both areas.
Email often contains sensitive or confidential information. When email encryption is employed, it provides the essential security needed to protect that information. Sending encrypted emails with Mimecast is as easy as selecting a checkbox. Learn more about email encryption and how to send encrypted email with Mimecast.
One of the simplest yet most overlooked email security practices is logging out of accounts when using shared or public devices. Failing to do so leaves the door open for unauthorized access. Make it a habit to log out of your email system every time you finish a session, especially when using devices that are not personally owned.
Is email secure? Not unless you adopt and implement advanced security techniques. When you're looking for ways to make email more secure, there are a few critical email security tips that can help.

Most IT teams are constantly sharing email security tips with employees in the hope that they will spot, delete, and report emails containing these types of threats.
But clearly, email security tips aren't enough to keep your organization safe. Even after training to spot attacks, 23% of phishing or spear-phishing emails are still opened by users. It's no wonder that major security breaches among Fortune 1000 companies continue to fill the headlines month after month.
That's why savvy organizations protect their data and their users by augmenting email security tips with powerful email security solutions from Mimecast.
Relying on a single security measure is no longer sufficient. Organizations should integrate multiple layers of protection to safeguard their email system. This includes using a secure email gateway (SEG), firewalls, and antivirus software to monitor and block malicious threats.
Regular updates to your email server settings and anti-malware databases are also essential to address new vulnerabilities as they arise. Combining different security technologies significantly reduces the chances of unauthorized access.
