Following a surge in demand, CounterTack added $3 million in venture capital funding from the Venture Capital unit of Siemens to round off its Series B funding at $15 million. CounterTack's Sentinel platform provides real-time security threat detection for enterprise clients. Enterprise security teams can use the platform not only to respond to current threats, but also identify trends and characteristics of attacker behavior to defend against future threats. After securing the venture capital funding, CounterTack also received an undisclosed amount of additional funding from OnPoint Technologies, a venture capital fund by the U.S. Department of Defense to develop products that interest the U.S. Army.
