Email security
The layer that inspects inbound and outbound mail for phishing, malware, impersonation, and data leakage.
Modern filtering goes well beyond spam scoring. It rewrites links so they can be checked at the moment of click rather than at delivery, detonates attachments, checks sender authentication, and flags messages that impersonate internal staff.
The gap it cannot close is a legitimate account that has been taken over, because the mail is genuinely from who it says. That is why mailbox behavior monitoring sits alongside filtering rather than being replaced by it.
Where this comes up
Email security sits inside our cybersecurity and threats work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
