The ThreatSmart™ Intrusion Detection system is a Perimeter owned proprietary technology.

ThreatSmart™ was designed to detect sophisticated intrusion attempts and to identify the activities of professional attackers. ThreatSmart™ uses sophisticated threat detection capabilities and integrates both signature-based intrusion detection technologies (which operate with real-time speed but only detect previously defined attacks) with analysis-based intrusion detection (which can detect network activity that is generally anomalous, but is slower and requires greater interpretation on the part of the security engineer) thus, creating Multi-Method Attack Detection. This allows ThreatSmart™ managed intrusion defense services to take advantage of the strengths of both detection capabilities without suffering the limitations of either.
