Intrusion

Intrusion is a cybersecurity company that provides network threat protection solutions using IP reputation intelligence. The company's platform, branded as "Intrusion Shield," is built around a Global Threat Engine that maintains reputation data on 8.5 billion IP addresses, sourced from intelligence used by the U.S. government over more than 30 years of operation. The company offers products across multiple deployment models: - On-Premise Network Protection: A physical appliance (Shield) that monitors all inbound and outbound network traffic and automatically blocks malicious or unknown connections without requiring traffic sampling or baselining. - Cloud Network Security: Shield Cloud, a gateway solution that sits between a virtual private cloud (VPC) and the public internet to enforce network security policies in cloud environments. - Endpoint Protection: Shield Endpoint, which enables secure remote connectivity and web browsing from any device, extending network protection to endpoints outside the corporate perimeter. - Threat Hunting & Consulting: A professional services offering where Intrusion's analysts conduct in-depth network analysis, threat intelligence reporting, and provide strategic guidance. The core technology approach, called Autonomous Network Enforcement, focuses on real-time identification and blocking of malicious connections based on IP reputation rather than behavioral baselining. The platform is designed to integrate into existing security architectures with minimal infrastructure changes and covers communications from unmanaged, unpatched, and legacy devices that cannot run endpoint software agents.
