CounterTack, a provider of cyber security technology, disclosed in a new filing with the Securities and Exchange Commission that it has raised $4.35 million in venture capital. Nine separate investors participated in the offering.

CounterTack is the industry's first and only in-progress attack intelligence and response solution that enables enterprise and government organizations to combat advanced targeted attacks with a new line of defense.

CounterTack offers the fastest detection and deepest attack intelligence available, which allows customers to actively engage with the attacker and take control over the impact of the attack - even while it's happening.

Founded as NeuralIQ, the company re-launched as CounterTack in 2011, building upon the vision and innovation of NeuralIQ. Based in Waltham, MA, the privately held company is backed by Fairhaven Capital and a group of private investors.
