Third Brigade is a privately-held security and compliance software company headquartered in Ottawa, Canada. Trend Micro bought the business to accelerate its dynamic datacenter security strategy, and to provide customers with access to critical security and compliance software and vulnerability response services. These all contribute to protecting physical, virtual and cloud servers, and corporate endpoints, from sophisticated malware and malicious activity.
