Mail Server Security

Anti-spam

Now using an enhanced, award-winning engine with improved performance, this essential component filters all spam emails and keeps user mailboxes free of unsolicited or undesired messages.

Anti-malware

Our second layer of protection built into ESET Mail Security provides detection of suspicious or malicious attachments to prevent users from being infected.

Anti-phishing

Prevents users from accessing phishing websites by filtering emails with malicious links. It can detect links with homoglyphs encoded in Punycode, where letters are swapped with similar-looking deceptive ones from different alphabets to impersonate well-known brands. These emails are flagged as phishing to protect users.

Rules

ESET’s comprehensive rule system allows administrators to manually define email filtering conditions and actions to take with the filtered emails.

Microsoft 365 mailbox scan

Enables businesses with a hybrid Exchange environment to scan Microsoft 365 remote mailboxes and public folders, similar to a traditional mailbox database scan. It also supports scanning remote mailboxes outside of the hybrid setup without requiring a connection to the local Active Directory.

Web-based quarantine

Emails are automatically provided to users about their spam emails that were quarantined.
