BlackICE products provide Intrusion Detection, personal firewall, and application protection all in one easy to use package. Our patent pending technology goes beyond scanning files to actually monitor ongoing system activity and communications across the Internet and automatically stop suspect activity before it can harm your system. BlackICE technology:

* Protects individual PCs by scrutinizing all traffic into and out from a computer, constantly on the lookout for suspicious activity and ready to aggressively defend against attack
* Blocks malicious activity from the source of the attack and denies improper access while leaving legitimate traffic unaffected
* Alerts users to attempted attacks and logs all suspicious activity so that sophisticated users or service providers can identify and neutralize the threat at its source
* Secures dial-up, DSL, or cable modem Internet connections 24 hours a day, 365 days a year
