Intrusion Inc. is a cybersecurity company headquartered in Plano, Texas that provides threat intelligence-driven security solutions. The company maintains a proprietary database containing historical data, known associations, and reputational behavior of over 8,500,000,000 Internet Protocol addresses. It leverages this intelligence to deliver products such as INTRUSION Shield, INTRUSION TraceCop, and INTRUSION Savant to protect networks and data. Its core mission is to enable organizations to stop sophisticated cyber threats before they cause damage by leveraging deep IP reputation insights.

Intrusion Inc. generates revenue primarily through the sale of its cybersecurity solutions, including software licenses, SaaS subscriptions, hardware appliances, and associated support and maintenance services. Revenue is derived from both direct sales to end users and indirect sales via system integrators, value-added resellers, and distributors. In 2024, sales to U. S. government entities accounted for 83.8% of total revenue, reflecting a strong reliance on federal, state, and local government contracts. The remaining revenue comes from commercial customers across industries such as manufacturing, conglomerates, and critical infrastructure, as well as modest foreign sales. The company also generates modest revenue from professional services such as deployment assistance, training, and custom threat analysis.

The company operates through the following segments:

• INTRUSION Shield: This segment provides a Zero Trust reputation-based Software as a Service solution that inspects and blocks malicious inbound and outbound network connections, available as Shield On-Premise, Shield Cloud, and Shield End-Point offerings. It continuously updates its threat intelligence to adapt to evolving attack techniques.

• INTRUSION TraceCop: This segment offers a big data tool with an extensive IP intelligence repository that supports forensic investigations by providing historical data on IP addresses, domain names, DNS resolutions, and network attributes. The tool also includes web-server surveys, OS fingerprints, and threat reputation histories for hostnames and IP addresses.

• INTRUSION Savant: This segment delivers a network monitoring solution that leverages TraceCop data to identify suspicious traffic in real-time, enabling forensic analysts to detect and investigate potential threats. Savant uses patented techniques to characterize network flows and allows users to create custom rules for packet header analysis.

Intrusion Inc. competes in the highly competitive network and data protection security market alongside firms such as Darktrace, Trellix, and Recorded Future. Its competitive advantage stems from the proprietary, historically enriched threat intelligence database that is difficult for rivals to replicate, creating a significant barrier to entry. The company positions its solutions as complementary to existing customer security stacks, emphasizing unique capabilities in detecting zero-day and malware-free compromises. Ongoing investment in research and development ensures that the threat database expands regularly with new IP associations and behavioral patterns.

Intrusion Inc. serves a diverse customer base that includes U. S. federal, state, and local government agencies, large conglomerates, manufacturing firms, and critical infrastructure operators. In 2024, sales to U. S. government entities represented 83.8% of revenue, with three individual government customers each exceeding 10% of total sales. The remaining business comes from commercial enterprises across various sectors and a small portion of foreign sales, which accounted for 4.7% of revenue in the same year. The company relies on direct sales channels as well as indirect channels through system integrators and resellers to reach its customers. This concentration in government sales creates revenue concentration risk, although the long-standing relationships provide a stable base for future growth.
