About Intrusion INC

Intrusion Inc. (ticker INTZ) is a U.S.-based cybersecurity company listed on the NASDAQ Capital Market in the United States. For French-speaking investors, it is best viewed as a small-cap technology name focused on cyberattack prevention, with a business model centered on detecting, filtering, and blocking malicious network connections in real time. The company was founded in Texas in September 1983 and later reincorporated in Delaware in October 1995. Its headquarters are in Plano, Texas, placing it within one of the major technology corridors in the southern United States. Intrusion’s history is notable for an initial long phase serving government customers with its TraceCop and Savant solutions, followed by a commercial expansion that began with the launch of INTRUSION Shield in 2021. Shield is positioned as a Zero Trust, reputation-based security product that leverages the company’s proprietary threat intelligence database, which it says contains more than 8.5 billion IP addresses and domain names. The core value proposition is straightforward: help organizations identify and stop known malicious or unknown risky connections before they can enter or leave a network. This is particularly relevant for use cases such as ransomware defense and protection against zero-day attacks. The company’s product set is therefore relatively focused: threat intelligence, network security, and proactive prevention solutions for businesses of all sizes and industries. That narrow specialization gives Intrusion a clear niche, but it also means the company competes against much larger and better-capitalized cybersecurity vendors. In competitive terms, Intrusion is not trying to be a broad platform provider; rather, it differentiates itself through proprietary intelligence and a practical, reputation-based blocking approach that can be layered into existing infrastructure. Geographically, Intrusion remains primarily U.S.-centric, with operations anchored in Texas and a market opportunity that can extend beyond the domestic market through software delivery. Recent corporate developments indicate that the company continues to prioritize financing and balance-sheet management: in 2025 it completed equity-related capital raises, including a registered direct offering and an at-the-market program, and in April 2026 it entered into a secured note transaction with Streeterville Capital. Recent quarterly filings also show continued net losses, underscoring that this remains a development-stage cybersecurity company rather than a mature, consistently profitable business. For investors, the story is one of a niche cyber-prevention specialist with a long operating history, a distinct technical database asset, and ongoing execution and financing risk.
