For Those Managing Domains
to Protect Their Brand
Even Domains That Don't Use Email
Are Being Targeted
Simply registering a domain isn't enough to prevent email spoofing. Attackers can still send emails impersonating your company. "GMO Spoofed Email Block" stops these emails from reaching recipients and gives you visibility into spoofing activity.
Is Someone Impersonating
Your Company
Without Your Knowledge?
Email spoofing can put your business
at risk in several ways.
Risk 1
Business Email Compromise (BEC)
Fraudulent emails impersonating company executives can cause financial losses for your business and its partners.
Risk 2
Phishing Attacks
Targeting CustomersAttackers impersonate your brand in emails to trick customers into visiting phishing websites.
Risk 3
Damage to Your Brand
If customers begin to distrust emails associated with your company, years of hard-earned trust can be lost.
Email spoofing puts both recipients and
the reputation of the impersonated company at risk.
Why Are Unused Domains
Vulnerable to
Email Spoofing?
Email sender addresses can be forged. Without authentication measures such as SPF and DMARC,
attackers can send emails that appear to come from your domain.
Receiving mail servers may be unable to identify and block these fraudulent messages.
1The Sender Address Is Spoofed
A third party sends an email using your company’s domain as the sender address.
2Unchecked Delivery Due to Lack of Authentication
Without SPF and DMARC, receiving mail servers may be unable to verify whether the email is legitimate.
3The Email Reaches the Recipient
The spoofed email is delivered directly to the recipient's inbox.
Without email authentication,
spoofed emails may be delivered directly to recipients.
Stop Dangerous Emails
Before They Reach Recipients
GMO Spoofed Email Block combines two approaches to combat email spoofing.
APPROACH 01 — BLOCKING

Spoofed Email Delivery
We configure SPF and DMARC (p=reject) for your protected domains to significantly reduce the risk of spoofed emails reaching recipients.
APPROACH 02 — MONITORING
