Trend Micro is to offer the InterCloud Security Service, a "Botnet" control service for ISPs and other large network service providers.
The service uses in-house-developed software called the Behavioral Analysis Security Engine (BASE). This is bundled with a hardware appliance and per-seat pricing.
According to Trend's press release, "InterCloud Security Service specifically addresses the mounting threat posed by botnets—networks of compromised machines that can be remotely controlled by an attacker. Threats associated with botnets include click-fraud, distributed denial-of-service attacks (DDoS), spam, identity theft via phishing and pharming techniques and other crimeware-related activity. "
