Reference excerpt

Intrusion Inc. (ticker: INTZ) is a cybersecurity company based in Plano, Texas. It provides cybersecurity solutions, including network intrusion detection and prevention systems.

History Intrusion Inc. was founded in 1983 as Optical Data Systems by G. Ward Paxton Jr. and Joe Head.

1990s In the early 1990s, Optical Data Systems was formed to provide network security products. In 1992, Optical Data Systems (ticker: ODSI) held its initial public offering, raising $17.1 million with a valuation of $99 million. In the mid-1990s, Intrusion had two business units: the Essential Communications division and the company's LAN division. Products included:

ODS Infiniti series switches, which supported Ethernet, ATM25, Token Ring and FDDI switching modules ODS GSN 6400 switches capable of transferring 6400 megabits per second per port for an aggregate switch bandwidth of 512 gigabits per second In 1998, ODS Networks acquired Essential Communications Corporation, a producer of switches and Ethernet products. In 1999, ODS Networks formed Intrusion.com Inc., a wholly owned subsidiary with a focus on the information security business.

2000s On June 1, 2000, the name changed from ODS Networks Inc. to Intrusion.com, Inc., and its ticker symbol from ODSI to INTZ. On November 1, 2001, the company changed its name again from Intrusion.com, Inc. to Intrusion Inc. Intrusion announced a $800,000 contract with Fort Hood to deploy Infinity flow-enabled switching products to provide insider threat protection.

2020s In 2020, Jack Blount was appointed CEO and changed the focus toward developing a new network detection and response product named Intrusion Shield. The company relocated its headquarters from Richardson, Texas to Plano, Texas. Blount resigned as CEO in 2021 amid SEC allegations of false and misleading claims. In 2021, Tony Scott, a former Chief Information Officer of the United States, was appointed President and CEO of the company.

Worked examples

Example 1 — a first encounter with Intrusion Inc.

Start with the simplest possible case. Write down what Intrusion Inc. claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Intrusion Inc. before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Intrusion Inc. ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Intrusion Inc.

In research: Intrusion Inc. appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Intrusion Inc. in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Intrusion Inc. is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network security, Computer security companies, Intrusion detection systems, so understanding it makes those chapters shorter.
In everyday life: Look for Intrusion Inc. outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
