Description of Business	1. Description of Business Intrusion, Inc. (together with its consolidated subsidiaries, the “Company”, Intrusion”, “Intrusion Inc.”, “we”, “us”, “our”, or similar terms) was organized in Texas in September 1983 and reincorporated in Delaware in October 1995. Our principal executive offices are located at 101 East Park Boulevard, Suite 1200, Plano, Texas 75074, and our telephone number is (972) 234-6400. Our website URL is www.intrusion.com. We develop, sell and support products that protect any-sized company or government organization by fusing advanced threat intelligence with real-time mitigation to kill cyberattacks as they occur – including Zero-Days. We market and distribute our solutions through a direct sales force and value-added resellers. Our end-user customers include U.S. federal government entities, state and local government entities, and companies ranging in size from mid-market to large enterprises. *Current Market Environment* In March 2020, the World Health Organization declared the ongoing coronavirus (COVID-19) outbreak a pandemic and recommended containment and mitigation measures worldwide. Our customers were forced to allocate scarce and competing resources and balance budgetary demands placed upon them as a result of the effects of the coronavirus, mandatory quarantines, decreased travel, interruptions in workforce populations, scarcity of commodities, and similar economic and operational effects of the virus upon their own constituencies. These adverse effects resulted in decreased demand by many of our customers for our product offerings and cybersecurity solutions, negatively affecting revenue levels for the Company. We anticipate that our customers will continue to budget conservatively in the coming months, particularly as uncertainty remains about new strains and variants of the COVID-19 virus and potential future restrictions, slow-downs, or lock-downs. As of December 31, 2021, we had cash and cash equivalents of approximately $4,100,000, compared to approximately $16,704,000 as of December 31, 2020. We generated a net loss of $18,802,000 for the year ended December 31, 2021, compared to a net loss of $6,518,000 for the year ended December 31, 2020. Under our at-the-market offering, since January 1, 2022, we have received proceeds of approximately $1,000,000 net of fees from the sale of our common stock related to this program. Since the inception of the program in 2021, we have received proceeds of approximately $6,600,000 net of fees from the sale of our common stock related to this program. On March 10, 2022, we entered into and debt securities agreement that provides $10,000,000 in funds through two separate fundings throughout 2022. Based on the current forecast for the year 2022, we believe that we will have sufficient cash resources to finance our operations and expected capital expenditures through March 18, 2023. We will continue to streamline our sales and marketing departments to better align expenses with revenue and build the customer base for our new INTRUSION Shield product. If our operations do not generate positive cash flow in the upcoming year, or if we are not able to obtain additional debt or equity financing on terms and conditions acceptable to us, if at all, we may be unable to implement our business plan, fund our liquidity needs or even continue our operations. *TraceCop “(TraceCop™”)* and Savant (*“Savant™”) are registered trademarks of Intrusion Inc.
