Terminology

Cybersecurity terms, explained clearly for all experience levels

The cybersecurity world is full of acronyms, jargon, and terms that evolve as fast as the threats themselves. This glossary cuts through the complexity, offering plain-language explanations for both foundational and advanced security terms.
Whether you’re reading a compliance report, building a risk strategy, or trying to explain a term to your board or development team-this is your go-to reference.

It’s built for clarity, accuracy, and utility-because clear understanding is the first layer of defense.
