cybersecuritytechnical
Cybersecurity involves protecting computers, networks, and digital information from theft, damage, or unauthorized access. It is essential for safeguarding sensitive data and maintaining trust in digital systems, which matters to investors because strong cybersecurity reduces the risk of costly breaches and disruptions that can impact a company’s performance and reputation. Think of it as locking and safeguarding valuable information much like securing a safe to prevent theft.
information securitytechnical
Information security is the practice of protecting digital data and the systems that store, process, or transmit it from theft, damage, or unauthorized access. For investors it matters because breaches can lead to financial loss, legal penalties, operational disruption and damage to reputation—similar to a physical store losing inventory or customer trust—so stronger protections reduce risk and help preserve a company’s value.
cyber risk managementtechnical
Cyber risk management is the set of actions an organization takes to find, reduce and respond to threats from hackers, data breaches and system outages—like installing locks, alarms and emergency plans for a digital home. Investors care because effective cyber risk management lowers the chance of costly disruptions, regulatory fines and reputational damage that can hit revenue, increase expenses and make a company a riskier or less valuable investment.
threat detectiontechnical
Threat detection is the process of spotting signs that something harmful or unwanted is happening or about to happen to an organization—such as a cyberattack, fraud, data leak, product safety issue, or regulatory noncompliance. Think of it as a building’s smoke detector: it alerts managers early so they can stop damage, preserve operations and reputation, and avoid costly fines or loss of investor trust.
data loss preventiontechnical
A set of tools, policies and practices designed to stop sensitive information from being lost, stolen or sent outside an organization without permission. Think of it like locks, alarms and rules for a house that keep valuables inside; for investors, effective data loss prevention reduces the risk of costly data breaches, regulatory fines and reputational damage that can hurt revenue, increase expenses and lower a company’s market value.
