The result
Safer email, every day
Three layers working together.
Cleaner inboxes
Dangerous messages get caught and flagged before your team acts on them.
Verified sender
SPF, DKIM and DMARC help prove your emails really come from you.
A trained team
Phishing practice builds the habit of checking before clicking.
Do you work with Microsoft 365?
Yes. InboxGuard adds onto Microsoft 365 to catch the phishing and impersonation email that gets through Microsoft Defender, and we help secure Microsoft 365 email accounts and logins.
What is business email compromise?
Business email compromise is when criminals impersonate an owner, employee or vendor by email to steal money or data. The FBI reports $3.05 billion lost to business email compromise in 2025.
What are SPF, DKIM and DMARC?
They are email settings that prove your messages really come from your business. Set up correctly, they make it much harder for criminals to send email pretending to be you.
