Email security - Active monitoring & response

overview.txt

🟢 🟡 🔴

Since May 2025, having DMARC set correctly for your domain is no longer optional.

Microsoft, Google, and Yahoo are now making it a requirement for senders to be properly authenticated. Senders without full authentication in place are at risk of being marked as spam, and even being blacklisted.

When you have properly configured SPF, DKIM, and DMARC records — industry-standard email authentication protocols — you take control of your domain and prevent abuse.

Avoid these threats

Business disruption caused by mopping up the mess caused by employees being caught out malicious emails.
Poor deliverability: real emails flagged as spam or blocked altogether
Phishing attacks: fake emails sent from “you” to trick recipients by spoofing your domain name.

Monitoring gives total visibility

You have visibility into the degree of spoofing attacks your domain Is undergoing.
Monitoring and reporting will alert you to out-of-process changes to the sending sources or domains. If your SPF and DKIM records for some reason were not updated, then legitimate email will be blocked.
Monitoring lets you determine the attack vector of spam received internally. Has an internal account been breached, or is an external attempt which has slipped through. Being able to diagnose the root of spam and phishing emails is key.
