Counter Link 

Counter Link provides communications interception solutions for IP networks.

Probes are provided for network speeds up to 200G.  The probes passively examine network traffic, looking for previously provisioned identifiers. Technologies include broadband intercept, multimedia VoIP, wireless, and RCS.  Intercepted information is passed to law-enforcement collection systems, formatted in several U.S. and international electronic-surveillance handover standards.  An extensive number of optional capabilities include intercept buffering, email alerting, content filtering, and tunneled inputs such as ERSPAN, VXLAN, GENEVE, EoMPLS, and others.

Counter Link also provides mediation software for active interception.  Support includes Nokia-based IMS's, Ribbon (Sonus, Genband) VoIP networks, Cataleya VoIP networks, and Arista Networks routers. 

For cloud-based services, Counter Link provides a virtualized intercept solution.  A software product called the VETapTM passively resides in the virtual servers of cloud service providers, tapping the network traffic and sending it through a private channel to a probe that is typically running as another virtual machine in the same cloud environment.

Counter Link is based in Cedar Mill, Oregon and was founded by the founder and CEO of RadiSys and IP Fabrics.
