INTRUSION Provides Information Refuting Negative Claims in Recently Published Short Report

PLANO, Texas, April 22, 2021 (GLOBE NEWSWIRE) — INTRUSION, Inc. (NASDAQ: INTZ), a leading provider of cyberattack prevention solutions including Zero-Days, was the subject of a short report issued on April 14, 2021.

As a result of the publication of this short report, several law firms have announced purported investigations into INTRUSION, with one firm filing a class action suit in the Eastern District of Texas on April 16, 2021 naming the Company’s chief executive officer and chief financial officer as defendants. This suit primarily repeats the allegations set forth in the short report.

INTRUSION believes the claims in the lawsuit are utterly without merit and intends to defend itself vigorously.

At this time, INTRUSION wishes to offer the following facts in contradiction of the findings of the short report and the allegations contained in the lawsuit:

• INTRUSION Shield is protected by two patents on existing technology: 8,291,058 and 8,472,449. In addition, the Company filed additional patents for Shield on August 20, 2020 which are currently pending.
• The Shield application – including the logic for Shield’s high-speed packet capture; connection reassembly; traffic decoding and analysis; patented packet file system; patented accumulators for performance; and kill logic – is proprietary INTRUSION-developed software containing over 1.1 million lines of code. The Shield application runs on a standard server hardware platform. The platform is based on certain open-source technologies such as the Linux operating system and uses open-source databases and libraries for data storage and secure communication layers, which is very common in security appliances.
• Shield is separate and distinct from its INTRUSION TraceCop offering. Shield leverages the TraceCop database to train Shield’s AI engine and drive its accuracy.
• Shield is in the early stage of its customer rollout and various companies, including Kimberly-Clark, Lippert Components, NovaTech, and others have entered into multi-year agreements for Shield.
• INTRUSION has the required certifications to ship Shield to every jurisdiction where it is being sold.
• Shield is categorized as a Network Defense and Response (NDR) product designed to kill malicious connections on a network as opposed to creating alerts about suspicious traffic that tend to overwhelm IT departments and provide notifications often after damage is done to a company’s network and data.
