CounterTack, which provides information about and protection against targeted attacks against commercial and government networks, says it’s taken another $5 million in investment money to continue scaling its business.

The new funding comes from Razor’s Edge Ventures and brings the CounterTack’s total investment take to $34.5 million.

“CounterTack’s innovative approach to endpoint threat detection and response helps significantly close the time delta between breach and remediation,” said Mark Spoto, managing director, Razor’s Edge Ventures.

“Legacy endpoint solutions are completely ineffective against the current cyber threat landscape such as advanced persistent threats and zero-day exploits.”

The endpoint threat detection and response market is all about detecting advanced threats and responding intelligently so that security teams can prioritize incidents.

Waltham, Massachusetts-based CounterTack competes with Mandiant, the other major player in the space.

CounterTack says it’s been experiencing unprecedented growth in 2014, driven by rising demand for its enterprise-class endpoint security platform, CounterTack Sentinel.
