INTRUSION INC

Intrusion Inc. (Nasdaq: INTZ) is a cybersecurity company that develops threat intelligence and network security solutions. The company maintains its corporate presence at www.intrusion.com and operates with a focus on identifying and preventing malicious network activity through proprietary data and advanced analytics.

The company's core offerings include the INTRUSION Shield family of products, a zero-trust reputation-based software-as-a-service platform that inspects network connections and blocks malicious traffic by analyzing IP addresses, domain information, and port utilization. INTRUSION Shield comprises three primary solutions: Shield On-Premise for data center deployment, Shield Cloud for protecting infrastructure-as-a-service and platform-as-a-service environments, and Shield Endpoint for remote workers and mobile devices. The company also offers INTRUSION TraceCop, a big data forensics tool containing reputation information on over 8.5 billion IP addresses accumulated over more than 20 years of internet intelligence gathering, and INTRUSION Savant, a network monitoring solution that identifies suspicious traffic in real-time.

Intrusion generates revenue through direct sales to government entities and indirect channels including system integrators, value-added resellers, and distributors. For the fiscal year ended December 31, 2025, the company generated revenues of approximately $7.1 million, with 94.6 percent derived from U.S. government customers. TraceCop represented 43.2 percent of existing revenues at $3.1 million. The company employs 52 people, including four part-time employees, and maintains operations in Plano, Texas, with additional remote personnel across multiple states.

The company's competitive advantages stem from its proprietary and comprehensive internet database developed over more than 25 years, which competitors would find extremely difficult to replicate. Intrusion holds two patents and has applied for additional patent protection for its INTRUSION Shield solutions. The company competes in the data mining and advanced persistent threat detection markets against established players including Darktrace, Trellix, and Recorded Future.
