GLOSSARY

Cybersecurity Glossary

Clear, no-nonsense definitions of the terms that come up most in security and compliance conversations.

Browse by category

Compliance & Governance

Compliance vocabulary causes more confusion in Greek mid-market security projects than any other category, largely because the terms overlap without meaning the same thing.

Threats & Attack Types

Most attacks that reach a mid-market company are not novel.

Security Operations & Detection

This is the category where acronyms are most often used as if they were interchangeable, and they are not.

Identity & Access

Identity has quietly become the primary control plane in most breaches.

Infrastructure, Data & Exposure

Everything in this category answers one of two questions: what is exposed, and what happens when something gets through.
