Email Spoofing & Impersonation Protection: How to Protect Your Business
Email is one of the most common ways cybercriminals target businesses.
A fraudulent message may look like it came from your CEO, an employee, a customer, a vendor—or even from your own email address. These attacks are commonly known as email spoofing, impersonation, and phishing.
Effective email spoofing & impersonation protection combines employee awareness with technologies such as SPF, DKIM, DMARC, MFA, and anti-phishing security.
The goal of these attacks is usually simple: trick someone into clicking a link, sharing a password, changing payment information, sending money, or providing sensitive information.
What Is Email Spoofing?
Email spoofing happens when an attacker makes a message appear to come from a legitimate email address or business domain.
For example, an employee may receive an email that appears to come from the company president even though the president never sent it.
What Is Email Impersonation?
Email impersonation occurs when an attacker creates an email address or domain that looks very similar to a legitimate one.
An employee may see the CEO's name in the sender field but fail to notice that the actual email address is slightly different.
That small difference can lead to a costly mistake.
What Employees Should Do When They Receive a Suspicious Email
When an email involves money, passwords, account changes, or sensitive information:
Check the full sender email address.
Be cautious with unexpected links and attachments.
Verify unusual financial requests by phone.
Use a phone number you already know instead of one listed in the suspicious email.
Report suspicious messages to your IT provider.
Never provide passwords or MFA verification codes by email.
Most importantly, don't assume an email is legitimate just because you recognize the sender's name.
How Email Spoofing & Impersonation Protection Helps Protect Your Business
Employees are an important part of cybersecurity, but businesses should not rely on employees to identify every attack.
Strong email spoofing & impersonation protection uses multiple layers of security to help reduce the risk of fraudulent messages reaching employees, customers, and business partners.
SPF
SPF helps identify which email servers are authorized to send email using your company's domain.
DKIM
DKIM digitally signs outgoing email so receiving systems can verify that the message is associated with an authorized sender.
DMARC
DMARC works with SPF and DKIM to help prevent unauthorized systems from sending email that appears to come from your domain.
Depending on how it is configured, suspicious email can be monitored, quarantined, or rejected.
Don't Forget Your Other Email Systems
Your Microsoft 365 account may not be the only system sending email for your company.
Email can also come from:
Website contact forms
Newsletters
CRM systems
Accounting applications
Appointment systems
Marketing platforms
Other third-party services
These systems need to be properly identified and authorized before stronger email security policies are implemented.
