What Sensitive and Confidential Information Is

Not all the information we handle every day has the same level of importance, and learning to distinguish what's sensitive or confidential is the first step to protecting it properly. Sensitive information usually refers to data that, if exposed, can cause direct harm to a person, such as health data, financial situation, ethnic origin or beliefs, while confidential information more broadly covers any data that the organization or a person decides not to make public, such as business strategies or internal contracts. A common mistake is assuming that only documents explicitly marked as confidential require care, when in reality much sensitive data circulates in everyday conversations, improvised spreadsheets or emails that were never formally labeled. Learning to identify this type of information the moment you receive or generate it, and not after it has already leaked, is what makes it possible to apply the right protections from the start, instead of reacting when the damage is already done.
