ESET Smart Security's Personal firewall provides bidirectional, stateful firewall protection with intrusion detection features. The three operational modes are:
All modes provide protocol filtering and intrusion detection.
A powerful feature of ESET Smart Security's Personal firewall is the ability to mark specific programs as being network-aware, in addition to web browsers such as Microsoft Internet Explorer and Mozilla Firefox.

The Antispam feature provides a highly reliable defense against annoying spam, as well as protection against email-borne threats that share many traits with normal spam.
Antispam utilizes both client- and server-based rules to provide up-to-the-minute spam prevention not attainable by other solutions requiring a continuous stream of downloads for detection.
