Whether it’s through phishing scams, malware, or ransomware, protecting your email system should be a top priority for any business. In this blog, we’ll walk through the best email protection practices to help keep your business secure, while ensuring your team can work efficiently.
Email security is a vast topic, but we’ll break it down into actionable steps that small businesses can easily implement with the help of IT support services.
Understanding the Threats to Small Businesses
Before diving into protection methods, it’s crucial to understand the most common email-based threats that small businesses face. Hackers frequently focus on small businesses, as these organisations often lack the robust cybersecurity measures that larger firms typically have in place. The most common threats include:
- Phishing Attacks – Cybercriminals often impersonate reputable organisations to trick employees into giving up sensitive information, such as login credentials.
- Malware and Ransomware – Malicious attachments or links in emails can infect your systems, stealing data or locking files until a ransom is paid.
- Business Email Compromise (BEC) – This attack involves impersonating executives or high-level employees to deceive others within the company into authorising fraudulent payments.
Now that we understand the threats, let’s look at some best practices to protect your small business from these dangers.
1. Implement Email Filtering Solutions
One of the first steps in protecting your business from email-based threats is implementing a strong email filtering solution. Email filters can block suspicious messages before they even reach your inbox, preventing phishing attempts, malware, and other harmful content. Many email service providers offer built-in filters, but it’s essential to ensure they are activated and configured correctly.
Advanced filtering tools can scan attachments, URLs, and the email’s metadata for signs of malicious activity, providing an additional layer of protection. For small businesses, investing in a third-party email security solution may be a wise decision for an extra level of defence.
2. Use Multi-Factor Authentication (MFA)
Multi-factor authentication (MFA) is an effective method of securing your email accounts. Even if a hacker manages to steal a password, MFA requires them to provide additional information, such as a text message code or fingerprint, before they can access the account.
By implementing multiple layers of verification beyond just a password, multi-factor authentication (MFA) greatly lowers the chances of unauthorised individuals accessing confidential business data. Enabling MFA for every employee, especially for accounts with access to critical data or financial transactions, should be a habit.
3. Train Employees on Email Security
In fact, many email-related breaches occur due to employees inadvertently clicking on malicious links or opening infected attachments. For this reason, offering consistent training on email safety is essential to keeping staff informed and reducing security risks.
Here are a few key lessons to include in your training:
- Recognise Phishing Attempts: Teach employees how to spot suspicious emails. Common signs include strange sender addresses, urgent requests, or generic greetings.
- Safe Handling of Attachments and Links: Encourage employees to avoid clicking on links or opening attachments unless they’re confident about the sender.
- How to Report Suspicious Emails: Make sure your team knows how to report any suspicious emails to the IT support team or IT helpdesk support, so that the threat can be analysed.
Regular training will ensure that your employees are equipped to spot threats and handle emails safely, reducing the risk of falling victim to cyberattacks.
4. Regularly Update Your Email System
Outdated software is an easy target for cybercriminals. Ensure that your email system and related applications are always up-to-date with the latest security patches. Many email systems have automatic update features, but it’s still essential to periodically check that updates are installed properly.
This goes beyond just your email provider. Ensure that all the apps and plugins integrated with your email system are updated too, as they may also have vulnerabilities that hackers could exploit.
5. Employ Strong Email Encryption
Email encryption is a fundamental practice that protects sensitive information from being intercepted by cybercriminals.
For businesses handling sensitive customer information, such as financial data or personal details, email encryption is crucial. This can be achieved through tools that encrypt emails automatically or by using secure email services designed for confidential communication.
If you’re working with external partners or clients, consider using secure portals or encrypted messaging services for sharing important documents instead of relying on regular email.
6. Use Robust Passwords
A strong password policy is one of the most basic yet essential methods of securing email accounts. Encourage employees to use complex passwords that include a mix of uppercase and lowercase letters, numbers, and symbols.
Additionally, avoid reusing passwords across multiple platforms and accounts. Password management tools can help store and generate secure passwords for your team members, ensuring that they don’t use weak or easily guessable passwords.
IT support small businesses can assist in setting up these systems, so your team doesn’t have to worry about managing passwords on their own.
7. Back-Up Your Email Data Regularly
Even with the best protection practices, sometimes things go wrong. Cybercriminals may still manage to infiltrate your systems, and email data could be lost or corrupted. Regularly backing up your email data ensures that, in the event of a breach, you can quickly restore your important information.
Cloud-based backup solutions can make this process seamless and more secure, providing automatic backups at scheduled intervals. This will also protect your business in the event of a ransomware attack, as you can restore data from a clean backup.
8. Monitor Email Traffic for Unusual Activity
Constantly monitoring email traffic for unusual patterns is crucial for detecting potential threats early. Look for signs such as an increased volume of emails from unknown addresses, multiple failed login attempts, or unusual attachment types.
You can set up automated alerts to notify you of these suspicious activities, allowing you to act swiftly before the situation escalates. Partnering with an IT support small businesses provider can help set up these monitoring systems effectively.
Conclusion
Email security is a critical component of your small business’s overall cybersecurity strategy. By implementing strong email filtering, using MFA, providing employee training, keeping your system updated, encrypting your communications, and more, you can safeguard your business against common email-related threats.
Remember, email protection is an ongoing process. Regular updates, training, and monitoring are essential to keep your business secure from evolving cyber threats. With the right support, such as IT helpdesk support, your small business can navigate these challenges effectively.
