Protecting enterprise networks and cloud services

Invisinet products are used in enterprises, government networks, cloud environments, and the Industrial Internet of Things (IIoT).  Invisinet was initially funded by the U.S. Department of Defense in 2010 to commercialize our patented network security technologies.

A New Zero Trust Approach to Network and IIoT Security & Cyber Defense

Underlying Invisinet Transport Access Control (TAC) is our patented First Packet Authentication™ which conveys and authenticates identity in the first packet of a TCP network session request. This fundamental invention addresses a security gap in how TCP/IP operates: the inability to authenticate network traffic sources. TCP/IP runs the internet and was designed for connectivity not security. Without authenticating a TCP session, unidentified and unauthorized users and devices can scan, probe and access networks and cloud services. This inherent weakness is exploited in all cyber-attacks through the process of network scanning and reconnaissance, and it has been further exposed and magnified by cloud services, mobile connectivity, and the Internet of Things (IoT).

Deployed in enterprise & operational networks, and by cloud service providers to:


Isolate, and protect servers and cloud services from unidentified and unauthorized users.


Stop cyber-attacks by blocking scanning and reconnaissance – you can’t attack what you can’t see.


Segment networks and isolate IT and IIoT systems and devices to reduce risk and meet compliance requirements.
