Nature of Operations [Text Block]	1. Description of Business We develop, market, and support a family of entity identification, data mining, regulated information compliance and data privacy protection. Our product families include: TraceCop for identity identification, Savant for data mining and advanced persistent threat detection and Compliance Commander for regulated information and data privacy protection. Intrusion’s products help protect critical information assets by quickly detecting, protecting, analyzing and reporting attacks or misuse of classified, private and regulated information for government and enterprise networks. We market and distribute our products through a direct sales force to end-users, distributors and numerous system integrators, managed service providers and value-added resellers. Our end-user customers include banks, credit unions, other financial institutions, U.S. federal government entities, foreign government entities, hospitals and other healthcare providers. Essentially, our end-users can be defined as end-users requiring network security solutions for protecting their mission critical data. References to the “Company”, “we”, “us”, “our”, “Intrusion” or “Intrusion Inc.” refer to Intrusion Inc. and its subsidiaries. Compliance Commander™ and TraceCop™ are registered trademarks of Intrusion Inc. As of December 31, 2019, we had cash and cash equivalents of approximately $3,334,000, up from approximately $1,652,000 as of December 31, 2018. We generated a net income of $4,465,000 for the year ended December 31, 2019 compared to a net income of $2,287,000 for the year ended December 31, 2018. We are obligated to make payments of accrued dividends on all our outstanding shares of preferred stock that will reduce our available cash resources. Based on the current forecast for the year 2020, we believe that we will have sufficient cash resources to finance our operations and expected capital expenditures through March 31, 2021. As of October 24, 2019, our funding available from the CEO Note terminated. Our management will be assessing whether to replace this borrowing base and assessing what terms may be available to the Company, including whether any such terms available are acceptable to the Company, if at all (the “Potential Replacement Facility”). Any equity or debt financings, if available at all, may be on terms which are not favorable to us and, in the case of equity financings, may result in dilution to our stockholders. We expect to fund our operations through anticipated Company profits, possibly additional investments of private equity and debt, which, if we are able to obtain, will have the effect of diluting our existing common stockholders, perhaps significantly, and a possible Potential Replacement Facility. 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.
