Hunt Or Be Hunted

AI-Driven Detection For Threat Hunting

What We Do

coun•ter•flow  \ˈkau̇n-tər-flō \ verb - an action made in opposition to a network threat.  


:: Threat Hunting Is The New Black

Threat hunting is the emerging modis operandi in cybersecurity. Industry experts concede that eliminating threats entirely is impossible and breaches are inevitable. Defense-in-depth systems likes firewalls and intrusion detection are necessary; but, they are not sufficient.  As a result, security analysts are shifting from a passive "wait-and-see" mindset to an active "search-and-destroy" strategy.  

:: Network Forensics Is Alive And Well 

We are a highly motivated start-up with a mission to introduce the next generation of network forensics platform designed specifically for threat hunting.  We believe that threat hunting requires continuous analysis of forensic data like flow records, meta-data, and packets.  However, we recognize that the industry is challenged by the confluence of three concerns: 

  • Staggering volume of threat alerts
  • Increasing sophistication of attackers
  • Continuing shortage of talented cybersecurity analysts

In response, we propose that utilizing Machine Learning (ML) technologies to detect, discover, and deter threats is no longer a novel option.  It is a functional requirement that enables analysts to drastically reduce time to detection.

:: This Is Not Our First Rodeo

The founding team of CounterFlow is well-qualified and experienced in the field of network forensics and data science. We have diligently assembled an engineering team consisting of experts in the fields of packet processing, threat detection, data science, and visualization. We are hard at work implementing and introducing AI-driven solutions for threat hunting in Q4 of 2017.  The portfolio will consist of two products: CounterFlow Threat Sensors (including enterprise manager) and CounterFlow Intelligence Platform.
