What is enterprise email security?
Enterprise email security is the combination of filtering, authentication, detection and user controls that protect an organization from email-borne threats such as phishing, malware, impersonation and business email compromise (BEC), where attackers impersonate executives or suppliers to redirect payments.
SPF, DKIM and DMARC are DNS-based standards that prove which servers may send email for your domain and tell receivers what to do with messages that fail checks.

Email security FAQs
Common questions about securing business email.
What is business email compromise?
A scam where attackers use a compromised or spoofed email account to impersonate executives, staff or suppliers and trick victims into sending money or data.
What is DMARC and why does it matter?
DMARC tells receiving mail servers how to handle messages that fail SPF and DKIM checks for your domain. Enforcing DMARC prevents attackers from spoofing your exact domain and is now expected by major mailbox providers for bulk senders.
Do we need Defender for Office 365 Plan 2?
Plan 1 covers Safe Links, Safe Attachments and advanced anti-phishing. Plan 2 adds threat investigation and response tools and attack simulation training. Plan 2 is included in Microsoft 365 E5.
Is Microsoft 365 built-in email security enough?
Exchange Online Protection provides baseline filtering. Most organizations need Defender for Office 365, proper configuration and domain authentication for strong protection.
Can you help after a BEC incident?
Yes. We investigate the compromise, remove attacker access and rules, identify affected messages and harden the tenant to prevent recurrence.
