What is Email Security?

Email security is all about protecting the messages you send and receive, ensuring that no one can read, change, or use them without your permission. This includes blocking spam, stopping viruses, and keeping your login details private.

If you’re running a business, it’s likely you use email every day to communicate with customers, send files, or handle orders. Without the right protection, anyone could hack into your email, steal important information, or send fake messages pretending to be you. That’s where email security tips step in. It adds layers of protection to stop that from happening.

Why Email Security Matters for Small Businesses

Many small businesses think hackers only target large companies. But that’s not true. Hackers often target small businesses because they know the security may be weaker. Almost half of all cyberattacks hit small businesses.

According to CISA, over 90% of successful cyberattacks start with an email. If your email gets hacked, it can cause serious problems. Someone might steal money, leak private data, or damage your reputation. For example, a hacker could send fake emails to your clients asking for payments. If a client falls for it, not only do you lose money, but your customer may also stop trusting you.

IBM’s 2024 Cost of a Data Breach Report also found that the average breach costs businesses about $4.88 million. For many companies, a major attack could threaten their survival.

That’s why email security isn’t something to skip. It keeps your team safe, your business running smoothly, and your customers confident that you’re protecting their information.

Common Email Security Threats

Below are the most common email threats that small businesses are facing:

• Phishing Attacks: Attackers trick users into clicking fake links or sharing sensitive data by pretending to be trusted sources.
• Malware & Ransomware: Harmful software sent through email can steal data or lock files, demanding payment to restore access.
• Business Email Compromise (BEC): Hackers impersonate business owners or partners to request fake payments or sensitive information.
• Insider Threats: Employees may accidentally or intentionally expose email data, making internal monitoring and training essential.
• Account Takeovers: Attackers use stolen or guessed passwords to access accounts, send fake emails, or steal information.

Now you understand what email security is and why it’s so important to avoid possible threats, here are some tried-and-tested email security tips.

Let’s discuss each of them to explore email security tips:

Awareness & Best Practices

Educate Your Team

Your team is the first line of defense against email threats. That’s why you need to create awareness of email security tips so they can recognize and respond to suspicious emails.

Start with regular training sessions and use real-life examples to show:

• How phishing scams work.
• How malware can hide in attachments.
• How unauthorized access can compromise sensitive data.

You can also educate your employees about social engineering tactics, as cybercriminals use these tactics to trick employees into revealing information. They can pretend to be a trusted colleague or a known vendor.

So, train your team to verify email requests, especially those requesting financial information, login details, or urgent actions. Also, encourage everyone to confirm requests through trusted channels before responding.

Next, create clear email policies. Define what is and isn’t acceptable when using company email. Include guidelines on handling attachments, links, and requests for personal information. Outline steps for reporting fishy emails so employees know what to do if they spot a potential threat.

Preventing Phishing Attempts

Phishing scams are common email threats. They often resemble legitimate emails but are designed to steal your information. To avoid these scams, teach your employees/team about how to spot red flags, such as:

• Unexpected links.
• Suspicious attachments.
• Unfamiliar sender addresses.

If they find any of these, tell them to pause and think before clicking. They may also call the sender or use a verified website to confirm the request. This extra step can prevent costly mistakes.

Don’t Click Unverified Email Links

Links in emails can easily redirect you to fake, unsecured websites that are designed to steal your information. Before clicking, hover over the link to see where it is directed. If it doesn’t match the expected destination, don’t click it. Instead, go directly to the website’s original URL. This method ensures you’re visiting a legitimate site, not a phishing page.

Separate Business & Personal Email

Mixing personal and work emails can create security risks. That’s why it’s essential to keep business emails on work accounts and personal emails on your personal accounts.

This separation reduces the chances of sensitive work data ending up in unsecured personal inboxes. Also, avoid forwarding work emails to personal accounts because this could expose confidential data to less secure networks or devices.

Password & Access Management

Always use passphrases to strengthen account protection because passwords are a major target for cybercriminals. A passphrase is a combination of unrelated words that are easy to remember but hard to crack, for example, RedPandaPizzaSky. Additionally, you can use a combination of upper and lower-case letters, numbers, and special characters (#$%@!). Never use common phrases or numbers, such as birthdays, names, or easy patterns (e.g., 123456).

Also, create strong and unique passwords for each account. Why? When you reuse passwords across different accounts, it increases the risk of a breach. If one account gets compromised, others can be accessed.

We recommend using a password manager for maintaining unique passwords across various accounts. These tools store passwords securely and generate complex ones that are difficult to guess.

Password Change Policies

Frequent password changes can either strengthen security or lead to weaker passwords if users choose simple patterns. Here, you need to assess whether regular changes are necessary depending on your business requirements.

Implement systems to monitor for compromised credentials. If a breach is detected, notify users immediately and require a password update. This approach ensures that password changes are made only when necessary and for valid reasons.

Enable MFA/2FA

Multi-Factor Authentication (MFA) and two-factor authentication (2FA) strengthen account protection by adding an extra verification step. Encourage your team to enable MFA or at least 2FA for all critical systems, especially email, cloud storage, and financial platforms, to reduce the risk of unauthorized access even if a password is compromised.

Those who enable MFA/2FA will need to enter the correct password and verify their identity through an additional method, such as receiving a text code.

Restrict Device Access

Limit email access to approved devices only. This way, you can control which devices connect to your business accounts. Ensure that all devices, whether laptops, tablets, or phones, have updated antivirus software and operating systems.

This is important because regular updates resolve security vulnerabilities and keep devices secure. Also, implementing a device management policy can help you monitor access and reduce the risk of unauthorized logins.

Always Log Out After Email Sessions

Never leave your email account open, especially on shared or public devices. If you do so and another person gets access to the device, they could easily access your emails and steal sensitive information.

To prevent unauthorized access, log out after each session. Also, enable automatic logout features. These settings log users out after a period of inactivity, reducing the risk of anyone accessing your email without your permission.

Email Security Tools & Protocols

Implement email authenticity protocols that act as a protective shield for your emails. Three essential protocols are:

1. Sender Policy Framework (SPF)
2. DomainKeys Identified Mail (DKIM)
3. Domain-Based Message Authentication, Reporting & Conformance (DMARC)

SPF verifies the sender’s identity to prevent fake emails. DKIM protocol adds a digital signature to confirm the email’s origin. However, DMARC helps prevent email spoofing by aligning SPF and DKIM records.

Ensure you regularly review and update these settings to strengthen email security. Also, monitoring these protocols ensures that unauthorized senders can’t pretend to be your business.

Use Advanced Security Tools

Basic security measures aren’t always enough. Implementing advanced security tips and tools is a practical email security tip to protect your business from sophisticated threats.

Email spam filters and malware scanners automatically detect and block harmful emails. They can identify suspicious attachments, links, and content before they reach your inbox.

Monitoring email traffic is another important step. Analyze patterns to find unusual activities, such as multiple login attempts or unexpected email forwarding. This helps you catch potential breaches early and respond quickly.

Use Encryption

When you send an email, it travels through multiple servers before reaching the recipient. If the email isn’t encrypted, hackers can intercept it and steal sensitive data. That’s why encrypting emails that contain confidential information is compulsory.

Choose email hosting services that offer end-to-end encryption. This means your emails stay protected from the moment you hit Send until they reach the recipient.

Network Safety & Device Usage

Public Wi-Fi may seem convenient, but it’s also risky because hackers can easily intercept data on unsecured networks. If you’re checking emails on public Wi-Fi, your login credentials, attachments, and sensitive messages may be exposed.

One of the essential email security tips for accessing email on public Wi-Fi is to use a Virtual Private Network (VPN) that creates a secure tunnel for your data, making it much harder for attackers to intercept your communication.

Data Management & Recovery

Don’t forget to implement email archiving and backup solutions because accidental deletion or malicious attacks can wipe out important emails. Email archiving automatically stores copies of all emails, making it easy to recover lost messages. However, backups ensure you can restore critical data if your primary email system is compromised.

Tools/Services for Enhanced Email Security

Using the right tools and services can make a difference to keeping your business email safe. To get started, look for email security tools that offer strong protection against spam, phishing, and malware.

They should scan attachments, block suspicious links, and help you spot fake emails before they cause harm. The best tools work in the background, so you don’t need to be a tech expert to use them.

For small businesses, budget is also important. You want something that offers strong protection without being too expensive. For this, trusted options that are easy to manage and affordable include:

• Google Workspace security features
• Microsoft Defender for Office 365
• SpamTitan
• Barracuda Email Protection.

Many of these also offer free trials, allowing you to test them before making a purchase. Once you pick a tool, ensure it works well with your existing email system. Whether you use Gmail, Outlook, or another provider, the tool should connect smoothly and not slow your site. Look for features:

• Quick setup
• Automatic updates
• A dashboard that shows real-time activity.

This facilitates managing everything in one place, getting alerts quickly, and staying on top of threats without switching between different apps.
