Spam and Malware Protection
Gateway filtering that blocks spam, malware and phishing before delivery.
"Gateway email filtering for organisations needing dependable pre-delivery protection against spam, phishing and viruses."
Block spam and malware before they reach mailboxes
High volumes of unsolicited email increase the risk of malware, phishing and ransomware entering corporate systems and interrupting workflows. Spam, malicious attachments and risky links create routine operational strain and raise the chance of user compromise.
Hornetsecurity's service scans and filters mail at the gateway to stop threats before delivery. Suspicious items are quarantined for admin review, attachments are inspected (including nested archives), links are rewritten through a secure gateway and live tracking provides immediate visibility into mail flow.
Where Spam and Malware Protection is used
Filter inbound and outbound mail to stop spam, viruses and phishing at the gateway while keeping quarantine volumes small and manageable. Administrators can apply policy-based attachment controls, nested-archive inspection and configurable compliance rules.
Use URL rewriting to reduce successful phishing clicks, enable advanced routing for distributed mail servers, and rely on live email tracking and searchable logs for rapid investigation and operational oversight.
