Email is still one of the most common ways that businesses communicate. But it’s also the number-one destination for crooks finding levers to pry on. Email threats, including phishing, malware, and business email compromise (BEC), are increasing and can lead to financial loss, reputation damage, and data breaches.
Leveraging best practices in email security should be a top priority for organizations to address these concerns. Here, in this post we’ll look at some of the best methods that businesses, Search for: Home Technology Enhanced Search for: Technology Top Email Security Best Practices for Your Business Enhanced It’s All It reports in a paper about the email security best practices.A Hacker can do much damage to a Business with just a single email. One of these, Mimecast, has garnered great praise for its strong email security. Though Mimecast can be an essential element in a strong security program, there are other important steps that businesses should take to maintain the safety of their user.
Email is an essential means of communication for businesses today, but its ubiquity makes it a popular target for attackers. Email security gaps are what cybercriminals use to get in and cause a range of damage, from rampant run-of-the-please-click-here phishing to ransomware delivery. The impact of succumbing to such attacks are grave, resulting in financial loss, legal implications, and a tarnished reputation for the institutions.
Without email security, businesses open themselves up to these dangers. This is where providers such as Mimecast can help, providing a proactive solution for keeping business communication safe.
Mimecast is a pioneer in cloud-based email security services. It provides a large number of features to help protect businesses from the many threats that they face via email. Whether you need email encryption, email continuity, archiving to the cloud or email spam filter, Mimecast has you covered.
It’s AI-driven email filtering tech is a great way to stop the bad emails finding their way into your team’s mailbox – goodbye phishing attempts and malware. Mimecast also offers deep threat intel, which is essential for identifying new threats on the fly. With the combination of Mimecast’s extensive security offerings, organizations are prepared to be one step ahead of malicious actors and protect their email traffic.
That said, as useful as Mimecast is, it is not a silver bullet. Like other email security tools, it should be used in addition to other methods of email security to offer a layered defense against the host of cyber threats that an organization may face.
Multi-factor authentication (MFA) is a fundamental step in bolstering email security. By requiring users to provide two or more verification factors (such as a password and a fingerprint or a code sent to their mobile device), MFA significantly reduces the chances of unauthorized access to email accounts.
MFA is particularly important for protecting sensitive business communication, as attackers often target email accounts to gain access to corporate systems or data. While Mimecast provides excellent protection against email-based threats, MFA adds an extra layer of security to prevent attackers from accessing email accounts even if they have managed to obtain login credentials through a breach.
Human error remains one of the leading causes of email security breaches. Employees may unknowingly open phishing emails, click on malicious links, or download infected attachments, all of which can lead to a security compromise. Regularly training staff on email security best practices is essential to reduce this risk.
A comprehensive training program should cover topics such as identifying phishing attempts, recognizing suspicious attachments, and understanding the risks associated with clicking on links from unknown sources. By fostering a security-conscious culture within the organization, businesses can empower employees to recognize and avoid potential threats before they escalate.
Mimecast plays an essential role in this process by providing educational resources and user-friendly security alerts to help employees identify dangerous emails. However, a combination of both technical safeguards and employee training creates a stronger defense against email-related cyber threats.
Weak passwords are a significant vulnerability in email security. Many people use simple passwords that are easy to guess or reuse the same password across multiple accounts, making it easier for attackers to gain unauthorized access to email accounts.
To mitigate this risk, businesses should enforce strong password policies that require employees to use complex, unique passwords for each account. Passwords should be a mix of uppercase and lowercase letters, numbers, and special characters, and they should be changed regularly. Additionally, businesses can consider using password managers to help employees securely store and manage their passwords.
When paired with Mimecast’s advanced email filtering and threat detection capabilities, strong passwords significantly enhance the security of business communications.
Email encryption is a crucial measure for protecting sensitive data and communications from unauthorized access. It ensures that any email content, including attachments, is securely encrypted during transit, making it unreadable to anyone without the proper decryption key.
For businesses that handle sensitive customer data, financial information, or proprietary intellectual property, email encryption is a non-negotiable security best practice. Mimecast’s encryption features offer an easy and seamless way to ensure that all outgoing emails are encrypted, reducing the risk of data breaches and ensuring compliance with data protection regulations.
Encryption also plays a vital role in protecting businesses from man-in-the-middle attacks, where cybercriminals intercept emails in transit to steal or alter the information being sent. By encrypting emails end-to-end, businesses can significantly reduce the likelihood of such attacks succeeding.
Spam emails and malicious attachments are common vehicles for phishing attacks and malware. Email filtering services, such as those offered by Mimecast, can help block these harmful emails before they reach employees’ inboxes. These filters scan incoming emails for known threats, suspicious attachments, and harmful URLs, quarantining anything deemed dangerous.
While spam filters are essential, they are not foolproof. Businesses should also encourage employees to be cautious when opening emails from unknown senders and to report suspicious emails to the IT department for further investigation.
By combining email filtering technologies with employee awareness and caution, businesses can significantly reduce the chances of a successful attack.
Data loss is a real concern for businesses, especially when dealing with malicious attacks such as ransomware, which can encrypt or delete email data. Regularly backing up email data is essential for ensuring that valuable information can be recovered in the event of an attack.
Mimecast provides email archiving solutions that allow businesses to back up their email data securely in the cloud. This ensures that even if an attacker manages to compromise a business’s email system, the data can be restored quickly, minimizing downtime and preventing significant loss of information.
Regularly scheduled backups, combined with encryption and other security measures, provide businesses with a robust data protection strategy that enhances overall email security.
Outdated software and systems are prime targets for cybercriminals, as they often contain known vulnerabilities that attackers can exploit. To ensure the highest level of security, businesses should regularly update their email servers, software applications, and security systems with the latest patches and fixes.
Mimecast’s cloud-based email security solutions help businesses stay ahead of emerging threats by automatically updating their systems with the latest security features and threat intelligence. This minimizes the risk of exploitation and helps ensure that email security remains as effective as possible.
Proactively monitoring email activity can help businesses detect unusual behavior and potential security threats. Monitoring tools allow companies to track inbound and outbound email traffic, flagging any suspicious activity such as unexpected file attachments or emails sent to a large number of recipients.
Mimecast’s threat intelligence features help businesses monitor email traffic in real-time, analyzing potential risks and providing alerts when abnormal activity is detected. By continuously monitoring email behavior, businesses can respond quickly to potential threats, mitigating the damage before it escalates.
Email security is a critical aspect of any business’s cybersecurity strategy. While solutions like Mimecast offer powerful protection against email-based threats, businesses must also implement additional best practices to ensure comprehensive security. By combining technologies like email filtering, encryption, and advanced threat intelligence with strong policies and employee training, businesses can build a robust defense against the growing array of cyber threats targeting email.
Ultimately, email security is not a one-time effort, but an ongoing commitment to protecting sensitive data and maintaining secure communication channels. By staying vigilant, adopting best practices, and leveraging the right tools, businesses can safeguard themselves against the ever-evolving landscape of cyber threats.
