Plixer works with IP host reputation data collected from US government agencies and service providers to track Emerging Threats data from around the world. Each Scrutinizer installation monitors for traffic to and from these hosts which include Distributed Command and Control and other types of malware. The data is updated several times per day to help ensure the highest potential network threat awareness.
